122264 ÷ 90 
We're looking to find how many times 90 goes into 122264.

Going ahead to step 1:
The number 90 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 90

Let's proceed to step 2:
The number 90 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 90

Going ahead to step 3:
The number 90 fits into 122 1 times, leaving a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 90 from 122, we get 32.
Bring next digit (2) of the dividend behind the 32 and repeat the process: 322 / 90

Going ahead to step 4:
The number 90 fits into 322 3 times, leaving a remainder of 52.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 270 from 322 leaves us with 52.
Take the next digit (6) from the dividend and append it to 52, then repeat: 526 / 90

On to step 5:
90 can be fit into 526 5 times, resulting in a remainder of 76.
Use 5 as the next digit of our solution. 
Result so far: 135.0
Subtract 450 from 526 to get 76.
Bring next digit (4) of the dividend behind the 76 and repeat the process: 764 / 90

Advancing to step 6:
90 goes into 764 8 times with a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 1358.0
If we subtract 720 from 764, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 7:
The number 90 fits into 440 4 times, leaving a remainder of 80.
Put 4 as the next digit of the answer. 
Result so far: 1358.4
If we take 360 away from 440, we end up 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.

Going ahead to step 8:
If we divide 800 by 90, we get 8 and a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 1358.48
Deduct 720 from 800 and we're left 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.

Moving on to step 9:
90 can be fit into 800 8 times, resulting in a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 1358.488
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 outcome is 1358.488, with a leftover of 0.008.
