96687128 ÷ 129 
We want to divide 96687128 by 129.

Going ahead to step 1:
9 divided by 129 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 129

Let's proceed to step 2:
The number 129 fits into 96 0 times, leaving a remainder of 96.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 96 and we're left with 96.
Append the next digit (6) from the dividend to 96 and continue with: 966 / 129

On to step 3:
966 divided by 129 is 7 with a remainder of 63.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 903 away from 966, we end up with 63.
Fetch the next digit (8) from the dividend, attach it to 63 and continue: 638 / 129

Step 4:
638 divided by 129 is 4 with a remainder of 122.
Record the quotient 4 as the next digit in the result. 
Result so far: 74.0
Deduct 516 from 638 and we're left with 122.
Take the next digit (7) from the dividend and append it to 122, then repeat: 1227 / 129

On to step 5:
The number 129 fits into 1227 9 times, leaving a remainder of 66.
Put 9 as the next digit of the answer. 
Result so far: 749.0
Deduct 1161 from 1227 and we're left with 66.
Take the next digit (1) from the dividend and append it to 66, then repeat: 661 / 129

Advancing to step 6:
The number 129 fits into 661 5 times, leaving a remainder of 16.
Write down 5 as next digit of the result. 
Result so far: 7495.0
The remainder is 16 after subtracting 645 from 661.
Append the next digit (2) from the dividend to 16 and continue with: 162 / 129

Step 7:
162 divided by 129 is 1 with a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 74951.0
If we take 129 away from 162, we end up with 33.
Take the next digit (8) from the dividend and append it to 33, then repeat: 338 / 129

Let's proceed to step 8:
If we divide 338 by 129, we get 2 and a remainder of 80.
The number 2 becomes the next digit in our result. 
Result so far: 749512.0
Subtract 258 from 338 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 9:
If we divide 800 by 129, we get 6 and a remainder of 26.
Write down 6 as next digit of the result. 
Result so far: 749512.6
Deduct 774 from 800 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 10:
When dividing 260 by 129, we get 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 749512.62
Deduct 258 from 260 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 11:
20 divided by 129 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 749512.62
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
The number 129 fits into 200 1 times, leaving a remainder of 71.
The next digit of our result is 1. 
Result so far: 749512.6201
The remainder is 71 after subtracting 129 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 13:
710 divided by 129 is 5 with a remainder of 65.
The next digit of our result is 5. 
Result so far: 749512.62015
Deduct 645 from 710 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 14:
129 goes into 650 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 749512.620155
Deduct 645 from 650 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 749512.620155 and a remainder of 5e-07.
