We're dividing 81561899 by 751 
Let's see how many times 751 fits into 81561899.

Advancing to step 1:
The number 751 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 751

Going ahead to step 2:
81 divided by 751 is 0 with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Bring next digit (5) of the dividend behind the 81 and repeat the process: 815 / 751

Going ahead to step 3:
The number 751 fits into 815 1 times, leaving a remainder of 64.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 751 from 815 leaves us with 64.
Include the next digit (6) from the dividend after 64, then repeat: 646 / 751

Let's proceed to step 4:
If we divide 646 by 751, we get 0 and a remainder of 646.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 646, we end up with 646.
Append the next digit (1) from the dividend to 646 and continue with: 6461 / 751

On to step 5:
751 goes into 6461 8 times with a remainder of 453.
The number 8 becomes the next digit in our result. 
Result so far: 108.0
The remainder is 453 after subtracting 6008 from 6461.
Bring next digit (8) of the dividend behind the 453 and repeat the process: 4538 / 751

Advancing to step 6:
If we divide 4538 by 751, we get 6 and a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 1086.0
Subtracting 4506 from 4538 leaves us with 32.
Grab the next digit (9) from the dividend, add it to 32, then carry on: 329 / 751

On to step 7:
The number 751 fits into 329 0 times, leaving a remainder of 329.
Write down 0 as next digit of the result. 
Result so far: 10860.0
Subtracting 0 from 329 leaves us with 329.
Include the next digit (9) from the dividend after 329, then repeat: 3299 / 751

Advancing to step 8:
3299 divided by 751 is 4 with a remainder of 295.
Record the quotient 4 as the next digit in the result. 
Result so far: 108604.0
If we subtract 3004 from 3299, we get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Let's proceed to step 9:
When dividing 2950 by 751, we get 3 with a remainder of 697.
Use 3 as the next digit of our solution. 
Result so far: 108604.3
The remainder is 697 after subtracting 2253 from 2950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6970, and continue the process.

Moving on to step 10:
6970 divided by 751 is 9 with a remainder of 211.
The next digit of our result is 9. 
Result so far: 108604.39
Deduct 6759 from 6970 and we're left with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

On to step 11:
2110 divided by 751 is 2 with a remainder of 608.
The number 2 becomes the next digit in our result. 
Result so far: 108604.392
If we subtract 1502 from 2110, we get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Let's proceed to step 12:
The number 751 fits into 6080 8 times, leaving a remainder of 72.
Use 8 as the next digit of our solution. 
Result so far: 108604.3928
The remainder is 72 after subtracting 6008 from 6080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 13:
If we divide 720 by 751, we get 0 and a remainder of 720.
Write down 0 as next digit of the result. 
Result so far: 108604.3928
The remainder is 720 after subtracting 0 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Advancing to step 14:
751 can be fit into 7200 9 times, resulting in a remainder of 441.
Write down 9 as next digit of the result. 
Result so far: 108604.392809
Subtracting 6759 from 7200 leaves us with 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

Let's proceed to step 15:
The number 751 fits into 4410 5 times, leaving a remainder of 655.
The next digit of our result is 5. 
Result so far: 108604.3928095
If we take 3755 away from 4410, we end up with 655.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

Moving on to step 16:
751 can be fit into 6550 8 times, resulting in a remainder of 542.
Record the quotient 8 as the next digit in the result. 
Result so far: 108604.39280958
Deduct 6008 from 6550 and we're left with 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Our division results in 108604.39280958 with a remaining 5.42e-07.
