Let's divide 921606 by 90
Let's see how many times 90 fits into 921606.

On to step 1:
If we divide 9 by 90, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 90

On to step 2:
The number 90 fits into 92 1 times, leaving a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 90 from 92, we get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 90

Let's proceed to step 3:
21 divided by 90 is 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 21 after subtracting 0 from 21.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 90

On to step 4:
90 can be fit into 216 2 times, resulting in a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 102.0
If we subtract 180 from 216, we get 36.
Append the next digit (0) from the dividend to 36 and continue with: 360 / 90

On to step 5:
The number 90 fits into 360 4 times, leaving a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 1024.0
If we take 360 away from 360, we end up with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 90

Advancing to step 6:
If we divide 6 by 90, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 10240.0
Deduct 0 from 6 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
60 divided by 90 is 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 10240.0
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 8:
600 divided by 90 is 6 with a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 10240.06
If we take 540 away from 600, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
600 divided by 90 is 6 with a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 10240.066
Subtracting 540 from 600 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

After the division, we end up with 10240.066 and a remainder of 0.006.
