We divide 122273 by 90
We want to figure out the number of times 122273 can be divided by 90.

Step 1:
If we divide 1 by 90, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 90

Step 2:
90 goes into 12 0 times with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 90

Going ahead to step 3:
90 goes into 122 1 times with a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 90 from 122 and we're left with 32.
Append the next digit (2) from the dividend to 32 and continue with: 322 / 90

On to step 4:
90 can be fit into 322 3 times, resulting in a remainder of 52.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 52 after subtracting 270 from 322.
Bring next digit (7) of the dividend behind the 52 and repeat the process: 527 / 90

Going ahead to step 5:
When dividing 527 by 90, we get 5 with a remainder of 77.
Put 5 as the next digit of the answer. 
Result so far: 135.0
Subtract 450 from 527 to get 77.
Include the next digit (3) from the dividend after 77, then repeat: 773 / 90

Advancing to step 6:
When dividing 773 by 90, we get 8 with a remainder of 53.
The number 8 becomes the next digit in our result. 
Result so far: 1358.0
If we take 720 away from 773, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 7:
The number 90 fits into 530 5 times, leaving a remainder of 80.
Put 5 as the next digit of the answer. 
Result so far: 1358.5
Subtracting 450 from 530 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 8:
The number 90 fits into 800 8 times, leaving a remainder of 80.
The next digit of our result is 8. 
Result so far: 1358.58
Subtracting 720 from 800 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 9:
90 can be fit into 800 8 times, resulting in a remainder of 80.
Put 8 as the next digit of the answer. 
Result so far: 1358.588
If we subtract 720 from 800, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final result is 1358.588 with a remainder of 0.008.
