89422 divided by 90 
Let's see how many times 90 fits into 89422.

Moving on to step 1:
8 divided by 90 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 90

Step 2:
When dividing 89 by 90, we get 0 with a remainder of 89.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 89 after subtracting 0 from 89.
Take the next digit (4) from the dividend and append it to 89, then repeat: 894 / 90

Step 3:
When dividing 894 by 90, we get 9 with a remainder of 84.
The next digit of our result is 9. 
Result so far: 9.0
If we take 810 away from 894, we end up with 84.
Grab the next digit (2) from the dividend, add it to 84, then carry on: 842 / 90

Going ahead to step 4:
90 can be fit into 842 9 times, resulting in a remainder of 32.
Use 9 as the next digit of our solution. 
Result so far: 99.0
Subtracting 810 from 842 leaves us with 32.
Include the next digit (2) from the dividend after 32, then repeat: 322 / 90

Going ahead to step 5:
322 divided by 90 is 3 with a remainder of 52.
Use 3 as the next digit of our solution. 
Result so far: 993.0
Subtracting 270 from 322 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 6:
If we divide 520 by 90, we get 5 and a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 993.5
If we take 450 away from 520, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 7:
700 divided by 90 is 7 with a remainder of 70.
The next digit of our result is 7. 
Result so far: 993.57
If we subtract 630 from 700, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 8:
700 divided by 90 is 7 with a remainder of 70.
Write down 7 as next digit of the result. 
Result so far: 993.577
If we subtract 630 from 700, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The quotient of the division is 993.577, and the remainder is 0.007.
