Let's divide 822621 by 90
We want to figure out the number of times 822621 can be divided by 90.

Moving on to step 1:
When dividing 8 by 90, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 90

Let's proceed to step 2:
The number 90 fits into 82 0 times, leaving a remainder of 82.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 82 leaves us with 82.
Include the next digit (2) from the dividend after 82, then repeat: 822 / 90

Advancing to step 3:
If we divide 822 by 90, we get 9 and a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 12 after subtracting 810 from 822.
Bring next digit (6) of the dividend behind the 12 and repeat the process: 126 / 90

On to step 4:
90 can be fit into 126 1 times, resulting in a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 91.0
The remainder is 36 after subtracting 90 from 126.
Fetch the next digit (2) from the dividend, attach it to 36 and continue: 362 / 90

Advancing to step 5:
When dividing 362 by 90, we get 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 914.0
Subtract 360 from 362 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 90

Going ahead to step 6:
If we divide 21 by 90, we get 0 and a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 9140.0
Subtracting 0 from 21 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 7:
90 can be fit into 210 2 times, resulting in a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 9140.2
If we subtract 180 from 210, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
90 can be fit into 300 3 times, resulting in a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 9140.23
Deduct 270 from 300 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 9:
90 can be fit into 300 3 times, resulting in a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 9140.233
If we subtract 270 from 300, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Our division results in 9140.233 with a remaining 0.003.
