Let's divide 868633 by 90
Let's see how many times 90 fits into 868633.

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
Deduct 0 from 8 and we're left with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 90

Going ahead to step 2:
90 goes into 86 0 times with a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Grab the next digit (8) from the dividend, add it to 86, then carry on: 868 / 90

Let's proceed to step 3:
90 can be fit into 868 9 times, resulting in a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 58 after subtracting 810 from 868.
Append the next digit (6) from the dividend to 58 and continue with: 586 / 90

Advancing to step 4:
90 goes into 586 6 times with a remainder of 46.
The number 6 becomes the next digit in our result. 
Result so far: 96.0
The remainder is 46 after subtracting 540 from 586.
Fetch the next digit (3) from the dividend, attach it to 46 and continue: 463 / 90

Going ahead to step 5:
463 divided by 90 is 5 with a remainder of 13.
Write down 5 as next digit of the result. 
Result so far: 965.0
If we take 450 away from 463, we end up with 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 90

Going ahead to step 6:
When dividing 133 by 90, we get 1 with a remainder of 43.
The number 1 becomes the next digit in our result. 
Result so far: 9651.0
The remainder is 43 after subtracting 90 from 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 7:
When dividing 430 by 90, we get 4 with a remainder of 70.
Record the quotient 4 as the next digit in the result. 
Result so far: 9651.4
The remainder is 70 after subtracting 360 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 8:
700 divided by 90 is 7 with a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 9651.47
The remainder is 70 after subtracting 630 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 9:
700 divided by 90 is 7 with a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 9651.477
Subtract 630 from 700 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 9651.477 with a remaining 0.007.
