80659901 ÷ 951 
We're looking to find how many times 951 goes into 80659901.

Advancing to step 1:
If we divide 8 by 951, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 951

Advancing to step 2:
80 divided by 951 is 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Fetch the next digit (6) from the dividend, attach it to 80 and continue: 806 / 951

Advancing to step 3:
The number 951 fits into 806 0 times, leaving a remainder of 806.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 806 leaves us with 806.
Include the next digit (5) from the dividend after 806, then repeat: 8065 / 951

Step 4:
8065 divided by 951 is 8 with a remainder of 457.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 7608 from 8065 to get 457.
Grab the next digit (9) from the dividend, add it to 457, then carry on: 4579 / 951

Advancing to step 5:
When dividing 4579 by 951, we get 4 with a remainder of 775.
Write down 4 as next digit of the result. 
Result so far: 84.0
Subtracting 3804 from 4579 leaves us with 775.
Grab the next digit (9) from the dividend, add it to 775, then carry on: 7759 / 951

Step 6:
When dividing 7759 by 951, we get 8 with a remainder of 151.
Write down 8 as next digit of the result. 
Result so far: 848.0
Deduct 7608 from 7759 and we're left with 151.
Take the next digit (0) from the dividend and append it to 151, then repeat: 1510 / 951

Advancing to step 7:
951 goes into 1510 1 times with a remainder of 559.
Record the quotient 1 as the next digit in the result. 
Result so far: 8481.0
Subtracting 951 from 1510 leaves us with 559.
Take the next digit (1) from the dividend and append it to 559, then repeat: 5591 / 951

On to step 8:
The number 951 fits into 5591 5 times, leaving a remainder of 836.
The number 5 becomes the next digit in our result. 
Result so far: 84815.0
If we take 4755 away from 5591, we end up with 836.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8360, and continue the process.

Moving on to step 9:
951 goes into 8360 8 times with a remainder of 752.
The number 8 becomes the next digit in our result. 
Result so far: 84815.8
Subtracting 7608 from 8360 leaves us with 752.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

Moving on to step 10:
951 goes into 7520 7 times with a remainder of 863.
Write down 7 as next digit of the result. 
Result so far: 84815.87
Subtract 6657 from 7520 to get 863.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8630, and continue the process.

Step 11:
951 goes into 8630 9 times with a remainder of 71.
Record the quotient 9 as the next digit in the result. 
Result so far: 84815.879
The remainder is 71 after subtracting 8559 from 8630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 12:
951 goes into 710 0 times with a remainder of 710.
Record the quotient 0 as the next digit in the result. 
Result so far: 84815.879
If we take 0 away from 710, we end up with 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Going ahead to step 13:
951 goes into 7100 7 times with a remainder of 443.
The number 7 becomes the next digit in our result. 
Result so far: 84815.87907
If we take 6657 away from 7100, we end up with 443.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

Going ahead to step 14:
The number 951 fits into 4430 4 times, leaving a remainder of 626.
Record the quotient 4 as the next digit in the result. 
Result so far: 84815.879074
Subtract 3804 from 4430 to get 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

On to step 15:
951 can be fit into 6260 6 times, resulting in a remainder of 554.
Put 6 as the next digit of the answer. 
Result so far: 84815.8790746
Subtracting 5706 from 6260 leaves us with 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Moving on to step 16:
The number 951 fits into 5540 5 times, leaving a remainder of 785.
The next digit of our result is 5. 
Result so far: 84815.87907465
Subtracting 4755 from 5540 leaves us with 785.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7850, and continue the process.

The final outcome is 84815.87907465, with a leftover of 7.85e-07.
