129611 ÷ 87 
We want to divide 129611 by 87.

On to step 1:
1 divided by 87 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 87

On to step 2:
87 goes into 12 0 times with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 87

Let's proceed to step 3:
When dividing 129 by 87, we get 1 with a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 42 after subtracting 87 from 129.
Include the next digit (6) from the dividend after 42, then repeat: 426 / 87

Advancing to step 4:
The number 87 fits into 426 4 times, leaving a remainder of 78.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we subtract 348 from 426, we get 78.
Append the next digit (1) from the dividend to 78 and continue with: 781 / 87

Advancing to step 5:
781 divided by 87 is 8 with a remainder of 85.
Use 8 as the next digit of our solution. 
Result so far: 148.0
If we subtract 696 from 781, we get 85.
Include the next digit (1) from the dividend after 85, then repeat: 851 / 87

On to step 6:
87 can be fit into 851 9 times, resulting in a remainder of 68.
Write down 9 as next digit of the result. 
Result so far: 1489.0
If we take 783 away from 851, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 7:
87 can be fit into 680 7 times, resulting in a remainder of 71.
Write down 7 as next digit of the result. 
Result so far: 1489.7
Subtracting 609 from 680 leaves us with 71.
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 8:
87 can be fit into 710 8 times, resulting in a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 1489.78
Subtract 696 from 710 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
The number 87 fits into 140 1 times, leaving a remainder of 53.
The number 1 becomes the next digit in our result. 
Result so far: 1489.781
Deduct 87 from 140 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 10:
87 can be fit into 530 6 times, resulting in a remainder of 8.
The next digit of our result is 6. 
Result so far: 1489.7816
Deduct 522 from 530 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
80 divided by 87 is 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 1489.7816
Subtract 0 from 80 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.

Advancing to step 12:
The number 87 fits into 800 9 times, leaving a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 1489.781609
The remainder is 17 after subtracting 783 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 13:
87 goes into 170 1 times with a remainder of 83.
Use 1 as the next digit of our solution. 
Result so far: 1489.7816091
If we subtract 87 from 170, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 14:
87 can be fit into 830 9 times, resulting in a remainder of 47.
Use 9 as the next digit of our solution. 
Result so far: 1489.78160919
Deduct 783 from 830 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The quotient of the division is 1489.78160919, and the remainder is 4.7e-08.
