857689 divided by 87 
Let's see how many times 87 fits into 857689.

Step 1:
8 divided by 87 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 87

Step 2:
85 divided by 87 is 0 with a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Grab the next digit (7) from the dividend, add it to 85, then carry on: 857 / 87

Moving on to step 3:
When dividing 857 by 87, we get 9 with a remainder of 74.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 783 from 857 to get 74.
Include the next digit (6) from the dividend after 74, then repeat: 746 / 87

Let's proceed to step 4:
If we divide 746 by 87, we get 8 and a remainder of 50.
Put 8 as the next digit of the answer. 
Result so far: 98.0
If we take 696 away from 746, we end up with 50.
Append the next digit (8) from the dividend to 50 and continue with: 508 / 87

Moving on to step 5:
The number 87 fits into 508 5 times, leaving a remainder of 73.
The next digit of our result is 5. 
Result so far: 985.0
Subtract 435 from 508 to get 73.
Include the next digit (9) from the dividend after 73, then repeat: 739 / 87

Going ahead to step 6:
When dividing 739 by 87, we get 8 with a remainder of 43.
Put 8 as the next digit of the answer. 
Result so far: 9858.0
Subtracting 696 from 739 leaves us 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.

Advancing to step 7:
87 goes into 430 4 times with a remainder of 82.
Put 4 as the next digit of the answer. 
Result so far: 9858.4
Subtracting 348 from 430 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 8:
When dividing 820 by 87, we get 9 with a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 9858.49
Subtracting 783 from 820 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 9:
87 can be fit into 370 4 times, resulting in a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 9858.494
Deduct 348 from 370 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.

On to step 10:
The number 87 fits into 220 2 times, leaving a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 9858.4942
Subtracting 174 from 220 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 11:
87 goes into 460 5 times with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 9858.49425
If we subtract 435 from 460, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 12:
87 can be fit into 250 2 times, resulting in a remainder of 76.
Write down 2 as next digit of the result. 
Result so far: 9858.494252
Subtracting 174 from 250 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 13:
87 goes into 760 8 times with a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 9858.4942528
The remainder is 64 after subtracting 696 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 14:
640 divided by 87 is 7 with a remainder of 31.
Record the quotient 7 as the next digit in the result. 
Result so far: 9858.49425287
Deduct 609 from 640 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The final result is 9858.49425287 with a remainder of 3.1e-08.
