We're dividing 85601388 by 987 
We want to divide 85601388 by 987.

Going ahead to step 1:
When dividing 8 by 987, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 987

Moving on to step 2:
If we divide 85 by 987, we get 0 and a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Grab the next digit (6) from the dividend, add it to 85, then carry on: 856 / 987

Let's proceed to step 3:
987 goes into 856 0 times with a remainder of 856.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 856, we end up with 856.
Append the next digit (0) from the dividend to 856 and continue with: 8560 / 987

Step 4:
If we divide 8560 by 987, we get 8 and a remainder of 664.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 7896 from 8560 and we're left with 664.
Take the next digit (1) from the dividend and append it to 664, then repeat: 6641 / 987

Going ahead to step 5:
6641 divided by 987 is 6 with a remainder of 719.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
The remainder is 719 after subtracting 5922 from 6641.
Append the next digit (3) from the dividend to 719 and continue with: 7193 / 987

Let's proceed to step 6:
987 can be fit into 7193 7 times, resulting in a remainder of 284.
Record the quotient 7 as the next digit in the result. 
Result so far: 867.0
Subtract 6909 from 7193 to get 284.
Fetch the next digit (8) from the dividend, attach it to 284 and continue: 2848 / 987

On to step 7:
2848 divided by 987 is 2 with a remainder of 874.
Record the quotient 2 as the next digit in the result. 
Result so far: 8672.0
The remainder is 874 after subtracting 1974 from 2848.
Include the next digit (8) from the dividend after 874, then repeat: 8748 / 987

Going ahead to step 8:
987 goes into 8748 8 times with a remainder of 852.
Put 8 as the next digit of the answer. 
Result so far: 86728.0
The remainder is 852 after subtracting 7896 from 8748.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8520, and continue the process.

On to step 9:
The number 987 fits into 8520 8 times, leaving a remainder of 624.
Record the quotient 8 as the next digit in the result. 
Result so far: 86728.8
Subtracting 7896 from 8520 leaves us with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Advancing to step 10:
If we divide 6240 by 987, we get 6 and a remainder of 318.
The number 6 becomes the next digit in our result. 
Result so far: 86728.86
Subtract 5922 from 6240 to get 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Going ahead to step 11:
987 can be fit into 3180 3 times, resulting in a remainder of 219.
Use 3 as the next digit of our solution. 
Result so far: 86728.863
If we subtract 2961 from 3180, we get 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

On to step 12:
When dividing 2190 by 987, we get 2 with a remainder of 216.
The next digit of our result is 2. 
Result so far: 86728.8632
Deduct 1974 from 2190 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Let's proceed to step 13:
The number 987 fits into 2160 2 times, leaving a remainder of 186.
Write down 2 as next digit of the result. 
Result so far: 86728.86322
Subtract 1974 from 2160 to get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

The final result is 86728.86322 with a remainder of 0.000186.
