Let's divide 857937 by 87
We want to figure out the number of times 857937 can be divided by 87.

Step 1:
87 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 87

Going ahead to step 2:
The number 87 fits into 85 0 times, leaving a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Take the next digit (7) from the dividend and append it to 85, then repeat: 857 / 87

Advancing to step 3:
87 goes into 857 9 times with a remainder of 74.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 783 from 857 to get 74.
Include the next digit (9) from the dividend after 74, then repeat: 749 / 87

Advancing to step 4:
The number 87 fits into 749 8 times, leaving a remainder of 53.
The next digit of our result is 8. 
Result so far: 98.0
If we subtract 696 from 749, we get 53.
Fetch the next digit (3) from the dividend, attach it to 53 and continue: 533 / 87

Step 5:
533 divided by 87 is 6 with a remainder of 11.
The next digit of our result is 6. 
Result so far: 986.0
Deduct 522 from 533 and we're left with 11.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 87

Step 6:
When dividing 117 by 87, we get 1 with a remainder of 30.
The next digit of our result is 1. 
Result so far: 9861.0
If we take 87 away from 117, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 7:
The number 87 fits into 300 3 times, leaving a remainder of 39.
The next digit of our result is 3. 
Result so far: 9861.3
The remainder is 39 after subtracting 261 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 8:
87 goes into 390 4 times with a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 9861.34
Subtract 348 from 390 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 9:
If we divide 420 by 87, we get 4 and a remainder of 72.
Use 4 as the next digit of our solution. 
Result so far: 9861.344
Subtracting 348 from 420 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

After the division, we end up with 9861.344 and a remainder of 0.0072.
