We divide 78725251 by 561
We want to figure out the number of times 78725251 can be divided by 561.

Moving on to step 1:
When dividing 7 by 561, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 561

Going ahead to step 2:
The number 561 fits into 78 0 times, leaving a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Take the next digit (7) from the dividend and append it to 78, then repeat: 787 / 561

Let's proceed to step 3:
If we divide 787 by 561, we get 1 and a remainder of 226.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 561 from 787, we get 226.
Grab the next digit (2) from the dividend, add it to 226, then carry on: 2262 / 561

Let's proceed to step 4:
561 can be fit into 2262 4 times, resulting in a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
The remainder is 18 after subtracting 2244 from 2262.
Grab the next digit (5) from the dividend, add it to 18, then carry on: 185 / 561

Advancing to step 5:
If we divide 185 by 561, we get 0 and a remainder of 185.
Write down 0 as next digit of the result. 
Result so far: 140.0
If we take 0 away from 185, we end up with 185.
Fetch the next digit (2) from the dividend, attach it to 185 and continue: 1852 / 561

Going ahead to step 6:
The number 561 fits into 1852 3 times, leaving a remainder of 169.
The number 3 becomes the next digit in our result. 
Result so far: 1403.0
If we take 1683 away from 1852, we end up with 169.
Take the next digit (5) from the dividend and append it to 169, then repeat: 1695 / 561

On to step 7:
561 goes into 1695 3 times with a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 14033.0
The remainder is 12 after subtracting 1683 from 1695.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 561

Step 8:
121 divided by 561 is 0 with a remainder of 121.
Write down 0 as next digit of the result. 
Result so far: 140330.0
Subtracting 0 from 121 leaves us with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Moving on to step 9:
When dividing 1210 by 561, we get 2 with a remainder of 88.
Write down 2 as next digit of the result. 
Result so far: 140330.2
If we take 1122 away from 1210, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 10:
When dividing 880 by 561, we get 1 with a remainder of 319.
Put 1 as the next digit of the answer. 
Result so far: 140330.21
If we subtract 561 from 880, we get 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Let's proceed to step 11:
561 can be fit into 3190 5 times, resulting in a remainder of 385.
Record the quotient 5 as the next digit in the result. 
Result so far: 140330.215
Subtract 2805 from 3190 to get 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Advancing to step 12:
3850 divided by 561 is 6 with a remainder of 484.
Record the quotient 6 as the next digit in the result. 
Result so far: 140330.2156
If we take 3366 away from 3850, we end up with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Going ahead to step 13:
561 goes into 4840 8 times with a remainder of 352.
The number 8 becomes the next digit in our result. 
Result so far: 140330.21568
If we subtract 4488 from 4840, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

On to step 14:
The number 561 fits into 3520 6 times, leaving a remainder of 154.
Put 6 as the next digit of the answer. 
Result so far: 140330.215686
The remainder is 154 after subtracting 3366 from 3520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Advancing to step 15:
The number 561 fits into 1540 2 times, leaving a remainder of 418.
Record the quotient 2 as the next digit in the result. 
Result so far: 140330.2156862
The remainder is 418 after subtracting 1122 from 1540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Step 16:
The number 561 fits into 4180 7 times, leaving a remainder of 253.
The number 7 becomes the next digit in our result. 
Result so far: 140330.21568627
Deduct 3927 from 4180 and we're left with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

In conclusion, the division gives 140330.21568627 with a balance of 2.53e-07.
