87385 divided by 90 
We want to divide 87385 by 90.

Going ahead to step 1:
90 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 90

Going ahead to step 2:
If we divide 87 by 90, we get 0 and a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Fetch the next digit (3) from the dividend, attach it to 87 and continue: 873 / 90

On to step 3:
When dividing 873 by 90, we get 9 with a remainder of 63.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 810 away from 873, we end up with 63.
Bring next digit (8) of the dividend behind the 63 and repeat the process: 638 / 90

On to step 4:
If we divide 638 by 90, we get 7 and a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 97.0
If we subtract 630 from 638, we get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 90

Step 5:
If we divide 85 by 90, we get 0 and a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 970.0
Subtracting 0 from 85 leaves us 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 6:
850 divided by 90 is 9 with a remainder of 40.
Record the quotient 9 as the next digit in the result. 
Result so far: 970.9
Deduct 810 from 850 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 7:
400 divided by 90 is 4 with a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 970.94
Subtracting 360 from 400 leaves us 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.

Step 8:
90 goes into 400 4 times with a remainder of 40.
The next digit of our result is 4. 
Result so far: 970.944
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 970.944, with a leftover of 0.004.
