Let's divide 87656749 by 129
We want to divide 87656749 by 129.

On to step 1:
The number 129 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 129

Going ahead to step 2:
129 goes into 87 0 times with a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Fetch the next digit (6) from the dividend, attach it to 87 and continue: 876 / 129

Step 3:
The number 129 fits into 876 6 times, leaving a remainder of 102.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 774 from 876 and we're left with 102.
Include the next digit (5) from the dividend after 102, then repeat: 1025 / 129

Advancing to step 4:
When dividing 1025 by 129, we get 7 with a remainder of 122.
Put 7 as the next digit of the answer. 
Result so far: 67.0
The remainder is 122 after subtracting 903 from 1025.
Fetch the next digit (6) from the dividend, attach it to 122 and continue: 1226 / 129

Step 5:
1226 divided by 129 is 9 with a remainder of 65.
The number 9 becomes the next digit in our result. 
Result so far: 679.0
Subtracting 1161 from 1226 leaves us with 65.
Append the next digit (7) from the dividend to 65 and continue with: 657 / 129

Advancing to step 6:
If we divide 657 by 129, we get 5 and a remainder of 12.
The next digit of our result is 5. 
Result so far: 6795.0
The remainder is 12 after subtracting 645 from 657.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 129

Advancing to step 7:
If we divide 124 by 129, we get 0 and a remainder of 124.
Put 0 as the next digit of the answer. 
Result so far: 67950.0
If we subtract 0 from 124, we get 124.
Bring next digit (9) of the dividend behind the 124 and repeat the process: 1249 / 129

Going ahead to step 8:
When dividing 1249 by 129, we get 9 with a remainder of 88.
Use 9 as the next digit of our solution. 
Result so far: 679509.0
If we take 1161 away from 1249, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 9:
If we divide 880 by 129, we get 6 and a remainder of 106.
The number 6 becomes the next digit in our result. 
Result so far: 679509.6
Deduct 774 from 880 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

On to step 10:
The number 129 fits into 1060 8 times, leaving a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 679509.68
Deduct 1032 from 1060 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 11:
129 goes into 280 2 times with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 679509.682
Deduct 258 from 280 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 12:
The number 129 fits into 220 1 times, leaving a remainder of 91.
The number 1 becomes the next digit in our result. 
Result so far: 679509.6821
Subtracting 129 from 220 leaves us with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Step 13:
When dividing 910 by 129, we get 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 679509.68217
If we take 903 away from 910, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 14:
70 divided by 129 is 0 with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 679509.68217
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 15:
If we divide 700 by 129, we get 5 and a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 679509.6821705
Subtract 645 from 700 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 16:
550 divided by 129 is 4 with a remainder of 34.
The next digit of our result is 4. 
Result so far: 679509.68217054
If we take 516 away from 550, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

After the division, we end up with 679509.68217054 and a remainder of 3.4e-08.
