Let's divide 636906 by 90
We want to figure out the number of times 636906 can be divided by 90.

Going ahead to step 1:
If we divide 6 by 90, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 90

Advancing to step 2:
The number 90 fits into 63 0 times, leaving a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Append the next digit (6) from the dividend to 63 and continue with: 636 / 90

Advancing to step 3:
90 goes into 636 7 times with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 630 from 636 and we're left with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 90

Going ahead to step 4:
69 divided by 90 is 0 with a remainder of 69.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
If we take 0 away from 69, we end up with 69.
Fetch the next digit (0) from the dividend, attach it to 69 and continue: 690 / 90

Moving on to step 5:
690 divided by 90 is 7 with a remainder of 60.
Write down 7 as next digit of the result. 
Result so far: 707.0
Deduct 630 from 690 and we're left with 60.
Include the next digit (6) from the dividend after 60, then repeat: 606 / 90

Going ahead to step 6:
90 goes into 606 6 times with a remainder of 66.
The next digit of our result is 6. 
Result so far: 7076.0
The remainder is 66 after subtracting 540 from 606.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 7:
If we divide 660 by 90, we get 7 and a remainder of 30.
Put 7 as the next digit of the answer. 
Result so far: 7076.7
If we subtract 630 from 660, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
If we divide 300 by 90, we get 3 and a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 7076.73
Subtract 270 from 300 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
The number 90 fits into 300 3 times, leaving a remainder of 30.
The next digit of our result is 3. 
Result so far: 7076.733
If we take 270 away from 300, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 7076.733 and a remainder of 0.003.
