88099467 divided by 561 
Our goal is to divide 88099467 by 561.

On to step 1:
561 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 561

On to step 2:
When dividing 88 by 561, we get 0 with a remainder of 88.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 88 after subtracting 0 from 88.
Grab the next digit (0) from the dividend, add it to 88, then carry on: 880 / 561

On to step 3:
561 can be fit into 880 1 times, resulting in a remainder of 319.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 319 after subtracting 561 from 880.
Include the next digit (9) from the dividend after 319, then repeat: 3199 / 561

On to step 4:
If we divide 3199 by 561, we get 5 and a remainder of 394.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 2805 from 3199 and we're left with 394.
Include the next digit (9) from the dividend after 394, then repeat: 3949 / 561

Moving on to step 5:
3949 divided by 561 is 7 with a remainder of 22.
Record the quotient 7 as the next digit in the result. 
Result so far: 157.0
If we subtract 3927 from 3949, we get 22.
Bring next digit (4) of the dividend behind the 22 and repeat the process: 224 / 561

Step 6:
The number 561 fits into 224 0 times, leaving a remainder of 224.
The next digit of our result is 0. 
Result so far: 1570.0
If we take 0 away from 224, we end up with 224.
Take the next digit (6) from the dividend and append it to 224, then repeat: 2246 / 561

On to step 7:
If we divide 2246 by 561, we get 4 and a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 15704.0
Deduct 2244 from 2246 and we're left with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 561

Let's proceed to step 8:
If we divide 27 by 561, we get 0 and a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 157040.0
Subtract 0 from 27 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 9:
270 divided by 561 is 0 with a remainder of 270.
Put 0 as the next digit of the answer. 
Result so far: 157040.0
Subtract 0 from 270 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Advancing to step 10:
561 can be fit into 2700 4 times, resulting in a remainder of 456.
Record the quotient 4 as the next digit in the result. 
Result so far: 157040.04
Subtract 2244 from 2700 to get 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Advancing to step 11:
4560 divided by 561 is 8 with a remainder of 72.
The next digit of our result is 8. 
Result so far: 157040.048
If we subtract 4488 from 4560, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 12:
561 goes into 720 1 times with a remainder of 159.
The next digit of our result is 1. 
Result so far: 157040.0481
If we take 561 away from 720, we end up with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

On to step 13:
561 can be fit into 1590 2 times, resulting in a remainder of 468.
Put 2 as the next digit of the answer. 
Result so far: 157040.04812
Subtract 1122 from 1590 to get 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

On to step 14:
If we divide 4680 by 561, we get 8 and a remainder of 192.
The number 8 becomes the next digit in our result. 
Result so far: 157040.048128
Deduct 4488 from 4680 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Let's proceed to step 15:
1920 divided by 561 is 3 with a remainder of 237.
The next digit of our result is 3. 
Result so far: 157040.0481283
If we subtract 1683 from 1920, we get 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Moving on to step 16:
The number 561 fits into 2370 4 times, leaving a remainder of 126.
The next digit of our result is 4. 
Result so far: 157040.04812834
If we take 2244 away from 2370, we end up with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

The final result is 157040.04812834 with a remainder of 1.26e-07.
