We're dividing 746396 by 90 
Our goal is to divide 746396 by 90.

Step 1:
If we divide 7 by 90, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 90

Going ahead to step 2:
When dividing 74 by 90, we get 0 with a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 74 to get 74.
Append the next digit (6) from the dividend to 74 and continue with: 746 / 90

On to step 3:
If we divide 746 by 90, we get 8 and a remainder of 26.
The next digit of our result is 8. 
Result so far: 8.0
If we take 720 away from 746, we end up with 26.
Append the next digit (3) from the dividend to 26 and continue with: 263 / 90

Advancing to step 4:
90 goes into 263 2 times with a remainder of 83.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
Deduct 180 from 263 and we're left with 83.
Grab the next digit (9) from the dividend, add it to 83, then carry on: 839 / 90

On to step 5:
When dividing 839 by 90, we get 9 with a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 829.0
If we subtract 810 from 839, we get 29.
Grab the next digit (6) from the dividend, add it to 29, then carry on: 296 / 90

On to step 6:
296 divided by 90 is 3 with a remainder of 26.
Write down 3 as next digit of the result. 
Result so far: 8293.0
If we take 270 away from 296, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 7:
90 goes into 260 2 times with a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 8293.2
Subtract 180 from 260 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 8:
The number 90 fits into 800 8 times, leaving a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 8293.28
If we subtract 720 from 800, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 9:
When dividing 800 by 90, we get 8 with a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 8293.288
If we take 720 away from 800, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final result is 8293.288 with a remainder of 0.008.
