We divide 863141 by 90
Let's see how many times 90 fits into 863141.

Moving on to step 1:
The number 90 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 90

On to step 2:
90 goes into 86 0 times with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Append the next digit (3) from the dividend to 86 and continue with: 863 / 90

Going ahead to step 3:
863 divided by 90 is 9 with a remainder of 53.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 810 from 863 to get 53.
Bring next digit (1) of the dividend behind the 53 and repeat the process: 531 / 90

Going ahead to step 4:
90 goes into 531 5 times with a remainder of 81.
Put 5 as the next digit of the answer. 
Result so far: 95.0
If we take 450 away from 531, we end up with 81.
Fetch the next digit (4) from the dividend, attach it to 81 and continue: 814 / 90

Step 5:
90 goes into 814 9 times with a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 959.0
Deduct 810 from 814 and we're left with 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 90

Advancing to step 6:
The number 90 fits into 41 0 times, leaving a remainder of 41.
The next digit of our result is 0. 
Result so far: 9590.0
Deduct 0 from 41 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 7:
90 goes into 410 4 times with a remainder of 50.
Record the quotient 4 as the next digit in the result. 
Result so far: 9590.4
Subtracting 360 from 410 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
When dividing 500 by 90, we get 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 9590.45
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 9:
If we divide 500 by 90, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 9590.455
If we subtract 450 from 500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

In conclusion, the division gives 9590.455 with a balance of 0.005.
