122954 ÷ 90 
We want to figure out the number of times 122954 can be divided by 90.

Advancing to step 1:
If we divide 1 by 90, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 90

On to step 2:
If we divide 12 by 90, we get 0 and a remainder of 12.
The next digit of our result is 0. 
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

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
If we take 90 away from 122, we end up with 32.
Grab the next digit (9) from the dividend, add it to 32, then carry on: 329 / 90

Advancing to step 4:
329 divided by 90 is 3 with a remainder of 59.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we take 270 away from 329, we end up with 59.
Include the next digit (5) from the dividend after 59, then repeat: 595 / 90

Going ahead to step 5:
The number 90 fits into 595 6 times, leaving a remainder of 55.
Write down 6 as next digit of the result. 
Result so far: 136.0
If we subtract 540 from 595, we get 55.
Take the next digit (4) from the dividend and append it to 55, then repeat: 554 / 90

Step 6:
The number 90 fits into 554 6 times, leaving a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 1366.0
Subtracting 540 from 554 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
90 can be fit into 140 1 times, resulting in a remainder of 50.
The next digit of our result is 1. 
Result so far: 1366.1
The remainder is 50 after subtracting 90 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
The number 90 fits into 500 5 times, leaving a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 1366.15
Subtracting 450 from 500 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 9:
90 goes into 500 5 times with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 1366.155
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 1366.155 and a remainder of 0.005.
