Let's divide 122524 by 90
We want to figure out the number of times 122524 can be divided by 90.

Moving on to step 1:
90 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 90

On to step 2:
90 goes into 12 0 times with 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.
Fetch the next digit (2) from the dividend, attach it to 12 and continue: 122 / 90

Step 3:
90 goes into 122 1 times with a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 90 from 122, we get 32.
Take the next digit (5) from the dividend and append it to 32, then repeat: 325 / 90

Advancing to step 4:
The number 90 fits into 325 3 times, leaving a remainder of 55.
Use 3 as the next digit of our solution. 
Result so far: 13.0
The remainder is 55 after subtracting 270 from 325.
Append the next digit (2) from the dividend to 55 and continue with: 552 / 90

Moving on to step 5:
The number 90 fits into 552 6 times, leaving a remainder of 12.
The next digit of our result is 6. 
Result so far: 136.0
Deduct 540 from 552 and we're left with 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 90

Going ahead to step 6:
124 divided by 90 is 1 with a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 1361.0
Subtract 90 from 124 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 7:
When dividing 340 by 90, we get 3 with a remainder of 70.
Use 3 as the next digit of our solution. 
Result so far: 1361.3
Deduct 270 from 340 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.

On to step 8:
700 divided by 90 is 7 with a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 1361.37
Subtracting 630 from 700 leaves us 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.

Moving on to step 9:
90 goes into 700 7 times with a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 1361.377
Subtracting 630 from 700 leaves us 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.

After the division, we end up with 1361.377 and a remainder of 0.007.
