Let's divide 903661 by 87
We're looking to find how many times 87 goes into 903661.

Moving on to step 1:
When dividing 9 by 87, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 87

Step 2:
87 can be fit into 90 1 times, resulting in a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 87 from 90 leaves us with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 87

On to step 3:
33 divided by 87 is 0 with a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 33 after subtracting 0 from 33.
Include the next digit (6) from the dividend after 33, then repeat: 336 / 87

Going ahead to step 4:
If we divide 336 by 87, we get 3 and a remainder of 75.
Record the quotient 3 as the next digit in the result. 
Result so far: 103.0
If we subtract 261 from 336, we get 75.
Take the next digit (6) from the dividend and append it to 75, then repeat: 756 / 87

On to step 5:
756 divided by 87 is 8 with a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 1038.0
Subtracting 696 from 756 leaves us with 60.
Bring next digit (1) of the dividend behind the 60 and repeat the process: 601 / 87

Step 6:
If we divide 601 by 87, we get 6 and a remainder of 79.
Write down 6 as next digit of the result. 
Result so far: 10386.0
The remainder is 79 after subtracting 522 from 601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 7:
The number 87 fits into 790 9 times, leaving a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 10386.9
Subtract 783 from 790 to get 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 8:
If we divide 70 by 87, we get 0 and a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 10386.9
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.

Step 9:
700 divided by 87 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 10386.908
The remainder is 4 after subtracting 696 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
If we divide 40 by 87, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 10386.908
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
87 can be fit into 400 4 times, resulting in a remainder of 52.
The next digit of our result is 4. 
Result so far: 10386.90804
Subtracting 348 from 400 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 12:
520 divided by 87 is 5 with a remainder of 85.
The next digit of our result is 5. 
Result so far: 10386.908045
Deduct 435 from 520 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 13:
The number 87 fits into 850 9 times, leaving a remainder of 67.
Put 9 as the next digit of the answer. 
Result so far: 10386.9080459
Deduct 783 from 850 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 14:
87 can be fit into 670 7 times, resulting in a remainder of 61.
Record the quotient 7 as the next digit in the result. 
Result so far: 10386.90804597
Subtracting 609 from 670 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

The quotient of the division is 10386.90804597, and the remainder is 6.1e-08.
