We look at the division of 747599 by 90 
We're looking to find how many times 90 goes into 747599.

Step 1:
The number 90 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 90

Step 2:
If we divide 74 by 90, we get 0 and a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Append the next digit (7) from the dividend to 74 and continue with: 747 / 90

Going ahead to step 3:
When dividing 747 by 90, we get 8 with a remainder of 27.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 720 from 747 to get 27.
Grab the next digit (5) from the dividend, add it to 27, then carry on: 275 / 90

Advancing to step 4:
If we divide 275 by 90, we get 3 and a remainder of 5.
The next digit of our result is 3. 
Result so far: 83.0
If we subtract 270 from 275, we get 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 90

Advancing to step 5:
The number 90 fits into 59 0 times, leaving a remainder of 59.
Use 0 as the next digit of our solution. 
Result so far: 830.0
Deduct 0 from 59 and we're left with 59.
Take the next digit (9) from the dividend and append it to 59, then repeat: 599 / 90

On to step 6:
90 can be fit into 599 6 times, resulting in a remainder of 59.
The number 6 becomes the next digit in our result. 
Result so far: 8306.0
The remainder is 59 after subtracting 540 from 599.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 7:
When dividing 590 by 90, we get 6 with a remainder of 50.
Use 6 as the next digit of our solution. 
Result so far: 8306.6
Subtracting 540 from 590 leaves us 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.

Let's proceed to step 8:
90 goes into 500 5 times with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 8306.65
Deduct 450 from 500 and we're left 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.

On to step 9:
The number 90 fits into 500 5 times, leaving a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 8306.655
The remainder is 50 after subtracting 450 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The quotient of the division is 8306.655, and the remainder is 0.005.
