We look at the division of 754598 by 90 
We want to figure out the number of times 754598 can be divided by 90.

Advancing to step 1:
The number 90 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 90

Going ahead to step 2:
The number 90 fits into 75 0 times, leaving a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Fetch the next digit (4) from the dividend, attach it to 75 and continue: 754 / 90

Advancing to step 3:
The number 90 fits into 754 8 times, leaving a remainder of 34.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 720 from 754, we get 34.
Fetch the next digit (5) from the dividend, attach it to 34 and continue: 345 / 90

Advancing to step 4:
The number 90 fits into 345 3 times, leaving a remainder of 75.
Use 3 as the next digit of our solution. 
Result so far: 83.0
If we take 270 away from 345, we end up with 75.
Grab the next digit (9) from the dividend, add it to 75, then carry on: 759 / 90

Moving on to step 5:
759 divided by 90 is 8 with a remainder of 39.
Record the quotient 8 as the next digit in the result. 
Result so far: 838.0
Deduct 720 from 759 and we're left with 39.
Bring next digit (8) of the dividend behind the 39 and repeat the process: 398 / 90

Let's proceed to step 6:
When dividing 398 by 90, we get 4 with a remainder of 38.
Write down 4 as next digit of the result. 
Result so far: 8384.0
If we take 360 away from 398, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 7:
The number 90 fits into 380 4 times, leaving a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 8384.4
If we take 360 away from 380, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
When dividing 200 by 90, we get 2 with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 8384.42
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
If we divide 200 by 90, we get 2 and a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 8384.422
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 8384.422 with a remainder of 0.002.
