We look at the division of 916598 by 90 
We want to figure out the number of times 916598 can be divided by 90.

Advancing to step 1:
The number 90 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 90

Moving on to step 2:
91 divided by 90 is 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 90 from 91, we get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 90

On to step 3:
90 can be fit into 16 0 times, resulting in a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 16 leaves us with 16.
Grab the next digit (5) from the dividend, add it to 16, then carry on: 165 / 90

Let's proceed to step 4:
165 divided by 90 is 1 with a remainder of 75.
Write down 1 as next digit of the result. 
Result so far: 101.0
Deduct 90 from 165 and we're left with 75.
Fetch the next digit (9) from the dividend, attach it to 75 and continue: 759 / 90

Going ahead to step 5:
When dividing 759 by 90, we get 8 with a remainder of 39.
The next digit of our result is 8. 
Result so far: 1018.0
Subtract 720 from 759 to get 39.
Fetch the next digit (8) from the dividend, attach it to 39 and continue: 398 / 90

Step 6:
90 goes into 398 4 times with a remainder of 38.
Record the quotient 4 as the next digit in the result. 
Result so far: 10184.0
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:
380 divided by 90 is 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 10184.4
The remainder is 20 after subtracting 360 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
200 divided by 90 is 2 with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 10184.42
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
When dividing 200 by 90, we get 2 with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 10184.422
The remainder is 20 after subtracting 180 from 200.
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 outcome is 10184.422, with a leftover of 0.002.
