Let's divide 839299 by 87
We want to figure out the number of times 839299 can be divided by 87.

On to step 1:
If we divide 8 by 87, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 87

Let's proceed to step 2:
87 goes into 83 0 times with a remainder of 83.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Grab the next digit (9) from the dividend, add it to 83, then carry on: 839 / 87

Step 3:
The number 87 fits into 839 9 times, leaving a remainder of 56.
The next digit of our result is 9. 
Result so far: 9.0
If we take 783 away from 839, we end up with 56.
Bring next digit (2) of the dividend behind the 56 and repeat the process: 562 / 87

On to step 4:
87 can be fit into 562 6 times, resulting in a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
Deduct 522 from 562 and we're left with 40.
Fetch the next digit (9) from the dividend, attach it to 40 and continue: 409 / 87

Advancing to step 5:
The number 87 fits into 409 4 times, leaving a remainder of 61.
The next digit of our result is 4. 
Result so far: 964.0
If we subtract 348 from 409, we get 61.
Take the next digit (9) from the dividend and append it to 61, then repeat: 619 / 87

Advancing to step 6:
When dividing 619 by 87, we get 7 with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 9647.0
Deduct 609 from 619 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
87 can be fit into 100 1 times, resulting in a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 9647.1
Subtracting 87 from 100 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 8:
87 can be fit into 130 1 times, resulting in a remainder of 43.
Write down 1 as next digit of the result. 
Result so far: 9647.11
If we take 87 away from 130, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

The final result is 9647.11 with a remainder of 0.043.
