990223 divided by 90 
We want to figure out the number of times 990223 can be divided by 90.

On to step 1:
90 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 90

Moving on to step 2:
90 can be fit into 99 1 times, resulting in a remainder of 9.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 90 from 99 to get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 90

Going ahead to step 3:
90 goes into 90 1 times with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 90 from 90, we get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 90

Moving on to step 4:
If we divide 2 by 90, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 110.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 90

On to step 5:
When dividing 22 by 90, we get 0 with a remainder of 22.
Use 0 as the next digit of our solution. 
Result so far: 1100.0
If we take 0 away from 22, we end up with 22.
Bring next digit (3) of the dividend behind the 22 and repeat the process: 223 / 90

On to step 6:
When dividing 223 by 90, we get 2 with a remainder of 43.
The next digit of our result is 2. 
Result so far: 11002.0
If we take 180 away from 223, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 7:
If we divide 430 by 90, we get 4 and a remainder of 70.
Record the quotient 4 as the next digit in the result. 
Result so far: 11002.4
Deduct 360 from 430 and we're left 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 8:
When dividing 700 by 90, we get 7 with a remainder of 70.
Record the quotient 7 as the next digit in the result. 
Result so far: 11002.47
Subtract 630 from 700 to 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.

Moving on to step 9:
90 can be fit into 700 7 times, resulting in a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 11002.477
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.

After the division, we end up with 11002.477 and a remainder of 0.007.
