We divide 122248 by 90
Our goal is to divide 122248 by 90.

Step 1:
The number 90 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 90

Going ahead to step 2:
90 can be fit into 12 0 times, resulting in a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Grab the next digit (2) from the dividend, add it to 12, then carry on: 122 / 90

Let's proceed to step 3:
If we divide 122 by 90, we get 1 and a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 32 after subtracting 90 from 122.
Bring next digit (2) of the dividend behind the 32 and repeat the process: 322 / 90

On to step 4:
When dividing 322 by 90, we get 3 with a remainder of 52.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we subtract 270 from 322, we get 52.
Include the next digit (4) from the dividend after 52, then repeat: 524 / 90

Moving on to step 5:
When dividing 524 by 90, we get 5 with a remainder of 74.
Use 5 as the next digit of our solution. 
Result so far: 135.0
Deduct 450 from 524 and we're left with 74.
Include the next digit (8) from the dividend after 74, then repeat: 748 / 90

Going ahead to step 6:
90 goes into 748 8 times with a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 1358.0
Subtracting 720 from 748 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 7:
The number 90 fits into 280 3 times, leaving a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 1358.3
If we subtract 270 from 280, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
90 can be fit into 100 1 times, resulting in a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 1358.31
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
100 divided by 90 is 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1358.311
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 1358.311, with a leftover of 0.001.
