Let's divide 748610 by 90
We want to divide 748610 by 90.

Moving on to step 1:
90 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 90

Going ahead to step 2:
74 divided by 90 is 0 with a remainder of 74.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 74 after subtracting 0 from 74.
Bring next digit (8) of the dividend behind the 74 and repeat the process: 748 / 90

Advancing to step 3:
The number 90 fits into 748 8 times, leaving a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 720 from 748 leaves us with 28.
Include the next digit (6) from the dividend after 28, then repeat: 286 / 90

On to step 4:
90 can be fit into 286 3 times, resulting in a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 83.0
Deduct 270 from 286 and we're left with 16.
Take the next digit (1) from the dividend and append it to 16, then repeat: 161 / 90

Let's proceed to step 5:
90 goes into 161 1 times with a remainder of 71.
Put 1 as the next digit of the answer. 
Result so far: 831.0
Deduct 90 from 161 and we're left with 71.
Grab the next digit (0) from the dividend, add it to 71, then carry on: 710 / 90

Let's proceed to step 6:
90 can be fit into 710 7 times, resulting in a remainder of 80.
Record the quotient 7 as the next digit in the result. 
Result so far: 8317.0
Deduct 630 from 710 and we're left 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.

On to step 7:
90 can be fit into 800 8 times, resulting in a remainder of 80.
The next digit of our result is 8. 
Result so far: 8317.8
Subtracting 720 from 800 leaves us 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.

Step 8:
800 divided by 90 is 8 with a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 8317.88
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.

The final outcome is 8317.88, with a leftover of 0.08.
