We divide 78809038 by 561
Our goal is to divide 78809038 by 561.

Going ahead to step 1:
When dividing 7 by 561, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 561

Advancing to step 2:
561 can be fit into 78 0 times, resulting in a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Fetch the next digit (8) from the dividend, attach it to 78 and continue: 788 / 561

On to step 3:
561 can be fit into 788 1 times, resulting in a remainder of 227.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 561 from 788 and we're left with 227.
Fetch the next digit (0) from the dividend, attach it to 227 and continue: 2270 / 561

Let's proceed to step 4:
561 can be fit into 2270 4 times, resulting in a remainder of 26.
The next digit of our result is 4. 
Result so far: 14.0
Subtracting 2244 from 2270 leaves us with 26.
Take the next digit (9) from the dividend and append it to 26, then repeat: 269 / 561

Moving on to step 5:
If we divide 269 by 561, we get 0 and a remainder of 269.
Use 0 as the next digit of our solution. 
Result so far: 140.0
Subtract 0 from 269 to get 269.
Take the next digit (0) from the dividend and append it to 269, then repeat: 2690 / 561

Advancing to step 6:
The number 561 fits into 2690 4 times, leaving a remainder of 446.
Write down 4 as next digit of the result. 
Result so far: 1404.0
If we take 2244 away from 2690, we end up with 446.
Take the next digit (3) from the dividend and append it to 446, then repeat: 4463 / 561

Advancing to step 7:
4463 divided by 561 is 7 with a remainder of 536.
Write down 7 as next digit of the result. 
Result so far: 14047.0
If we take 3927 away from 4463, we end up with 536.
Take the next digit (8) from the dividend and append it to 536, then repeat: 5368 / 561

Step 8:
561 can be fit into 5368 9 times, resulting in a remainder of 319.
Write down 9 as next digit of the result. 
Result so far: 140479.0
The remainder is 319 after subtracting 5049 from 5368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Step 9:
The number 561 fits into 3190 5 times, leaving a remainder of 385.
Use 5 as the next digit of our solution. 
Result so far: 140479.5
The remainder is 385 after subtracting 2805 from 3190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

On to step 10:
The number 561 fits into 3850 6 times, leaving a remainder of 484.
Write down 6 as next digit of the result. 
Result so far: 140479.56
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.

On to step 11:
561 goes into 4840 8 times with a remainder of 352.
Record the quotient 8 as the next digit in the result. 
Result so far: 140479.568
Subtract 4488 from 4840 to 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 12:
When dividing 3520 by 561, we get 6 with a remainder of 154.
The number 6 becomes the next digit in our result. 
Result so far: 140479.5686
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 13:
If we divide 1540 by 561, we get 2 and a remainder of 418.
The next digit of our result is 2. 
Result so far: 140479.56862
If we take 1122 away from 1540, we end up with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

On to step 14:
The number 561 fits into 4180 7 times, leaving a remainder of 253.
Use 7 as the next digit of our solution. 
Result so far: 140479.568627
The remainder is 253 after subtracting 3927 from 4180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Let's proceed to step 15:
When dividing 2530 by 561, we get 4 with a remainder of 286.
Put 4 as the next digit of the answer. 
Result so far: 140479.5686274
Subtract 2244 from 2530 to get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Moving on to step 16:
561 goes into 2860 5 times with a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 140479.56862745
Subtracting 2805 from 2860 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The final outcome is 140479.56862745, with a leftover of 5.5e-08.
