We divide 78572233 by 561
We want to divide 78572233 by 561.

Step 1:
561 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 561

Going ahead to step 2:
78 divided by 561 is 0 with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Fetch the next digit (5) from the dividend, attach it to 78 and continue: 785 / 561

Moving on to step 3:
If we divide 785 by 561, we get 1 and a remainder of 224.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 561 from 785 to get 224.
Grab the next digit (7) from the dividend, add it to 224, then carry on: 2247 / 561

Let's proceed to step 4:
561 can be fit into 2247 4 times, resulting in a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we subtract 2244 from 2247, we get 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 561

Going ahead to step 5:
When dividing 32 by 561, we get 0 with a remainder of 32.
Use 0 as the next digit of our solution. 
Result so far: 140.0
Subtracting 0 from 32 leaves us with 32.
Take the next digit (2) from the dividend and append it to 32, then repeat: 322 / 561

Step 6:
561 can be fit into 322 0 times, resulting in a remainder of 322.
Use 0 as the next digit of our solution. 
Result so far: 1400.0
The remainder is 322 after subtracting 0 from 322.
Fetch the next digit (3) from the dividend, attach it to 322 and continue: 3223 / 561

On to step 7:
561 can be fit into 3223 5 times, resulting in a remainder of 418.
Use 5 as the next digit of our solution. 
Result so far: 14005.0
Subtracting 2805 from 3223 leaves us with 418.
Fetch the next digit (3) from the dividend, attach it to 418 and continue: 4183 / 561

Moving on to step 8:
When dividing 4183 by 561, we get 7 with a remainder of 256.
The next digit of our result is 7. 
Result so far: 140057.0
Subtract 3927 from 4183 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 9:
When dividing 2560 by 561, we get 4 with a remainder of 316.
Record the quotient 4 as the next digit in the result. 
Result so far: 140057.4
The remainder is 316 after subtracting 2244 from 2560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

On to step 10:
When dividing 3160 by 561, we get 5 with a remainder of 355.
Put 5 as the next digit of the answer. 
Result so far: 140057.45
Subtracting 2805 from 3160 leaves us with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Step 11:
The number 561 fits into 3550 6 times, leaving a remainder of 184.
The number 6 becomes the next digit in our result. 
Result so far: 140057.456
If we take 3366 away from 3550, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Let's proceed to step 12:
If we divide 1840 by 561, we get 3 and a remainder of 157.
Write down 3 as next digit of the result. 
Result so far: 140057.4563
The remainder is 157 after subtracting 1683 from 1840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Going ahead to step 13:
When dividing 1570 by 561, we get 2 with a remainder of 448.
Write down 2 as next digit of the result. 
Result so far: 140057.45632
Subtracting 1122 from 1570 leaves us with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Step 14:
561 goes into 4480 7 times with a remainder of 553.
Write down 7 as next digit of the result. 
Result so far: 140057.456327
If we take 3927 away from 4480, we end up with 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

Let's proceed to step 15:
The number 561 fits into 5530 9 times, leaving a remainder of 481.
The next digit of our result is 9. 
Result so far: 140057.4563279
Subtract 5049 from 5530 to get 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

Moving on to step 16:
561 can be fit into 4810 8 times, resulting in a remainder of 322.
Use 8 as the next digit of our solution. 
Result so far: 140057.45632798
If we subtract 4488 from 4810, we get 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

The quotient of the division is 140057.45632798, and the remainder is 3.22e-07.
