We're dividing 983422 by 90 
We're looking to find how many times 90 goes into 983422.

Step 1:
The number 90 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 90

Step 2:
If we divide 98 by 90, we get 1 and a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 90 from 98 leaves us with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 90

Moving on to step 3:
The number 90 fits into 83 0 times, leaving a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 83 leaves us with 83.
Include the next digit (4) from the dividend after 83, then repeat: 834 / 90

Advancing to step 4:
834 divided by 90 is 9 with a remainder of 24.
The number 9 becomes the next digit in our result. 
Result so far: 109.0
Deduct 810 from 834 and we're left with 24.
Take the next digit (2) from the dividend and append it to 24, then repeat: 242 / 90

Going ahead to step 5:
242 divided by 90 is 2 with a remainder of 62.
The next digit of our result is 2. 
Result so far: 1092.0
Deduct 180 from 242 and we're left with 62.
Append the next digit (2) from the dividend to 62 and continue with: 622 / 90

Moving on to step 6:
The number 90 fits into 622 6 times, leaving a remainder of 82.
Write down 6 as next digit of the result. 
Result so far: 10926.0
Subtract 540 from 622 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 7:
90 goes into 820 9 times with a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 10926.9
If we subtract 810 from 820, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
100 divided by 90 is 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 10926.91
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
If we divide 100 by 90, we get 1 and a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 10926.911
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 10926.911 with a remaining 0.001.
