Let's divide 636028 by 90
We're looking to find how many times 90 goes into 636028.

Going ahead to step 1:
6 divided by 90 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 90

Moving on to step 2:
90 goes into 63 0 times with a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Fetch the next digit (6) from the dividend, attach it to 63 and continue: 636 / 90

On to step 3:
90 goes into 636 7 times with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 6 after subtracting 630 from 636.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 90

Step 4:
90 goes into 60 0 times with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
The remainder is 60 after subtracting 0 from 60.
Append the next digit (2) from the dividend to 60 and continue with: 602 / 90

Moving on to step 5:
602 divided by 90 is 6 with a remainder of 62.
Record the quotient 6 as the next digit in the result. 
Result so far: 706.0
If we take 540 away from 602, we end up with 62.
Append the next digit (8) from the dividend to 62 and continue with: 628 / 90

Advancing to step 6:
90 goes into 628 6 times with a remainder of 88.
Use 6 as the next digit of our solution. 
Result so far: 7066.0
The remainder is 88 after subtracting 540 from 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 7:
When dividing 880 by 90, we get 9 with a remainder of 70.
Write down 9 as next digit of the result. 
Result so far: 7066.9
If we take 810 away from 880, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 8:
The number 90 fits into 700 7 times, leaving a remainder of 70.
Record the quotient 7 as the next digit in the result. 
Result so far: 7066.97
Deduct 630 from 700 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

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: 7066.977
If we subtract 630 from 700, we 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.

The final outcome is 7066.977, with a leftover of 0.007.
