745079 ÷ 90 
We want to divide 745079 by 90.

On to step 1:
The number 90 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 90

Going ahead to step 2:
74 divided by 90 is 0 with a remainder of 74.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Fetch the next digit (5) from the dividend, attach it to 74 and continue: 745 / 90

Going ahead to step 3:
90 goes into 745 8 times with a remainder of 25.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 720 away from 745, we end up with 25.
Bring next digit (0) of the dividend behind the 25 and repeat the process: 250 / 90

Step 4:
When dividing 250 by 90, we get 2 with a remainder of 70.
Use 2 as the next digit of our solution. 
Result so far: 82.0
The remainder is 70 after subtracting 180 from 250.
Bring next digit (7) of the dividend behind the 70 and repeat the process: 707 / 90

Going ahead to step 5:
When dividing 707 by 90, we get 7 with a remainder of 77.
The next digit of our result is 7. 
Result so far: 827.0
Deduct 630 from 707 and we're left with 77.
Append the next digit (9) from the dividend to 77 and continue with: 779 / 90

Step 6:
If we divide 779 by 90, we get 8 and a remainder of 59.
Use 8 as the next digit of our solution. 
Result so far: 8278.0
If we take 720 away from 779, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 7:
90 goes into 590 6 times with a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 8278.6
Subtract 540 from 590 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
90 goes into 500 5 times with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 8278.65
If we take 450 away from 500, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
When dividing 500 by 90, we get 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 8278.655
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final outcome is 8278.655, with a leftover of 0.005.
