We divide 120750 by 90
We want to divide 120750 by 90.

Step 1:
1 divided by 90 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
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:
90 goes into 12 0 times with 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 (0) from the dividend to 12 and continue with: 120 / 90

On to step 3:
The number 90 fits into 120 1 times, leaving a remainder of 30.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 90 from 120 and we're left with 30.
Grab the next digit (7) from the dividend, add it to 30, then carry on: 307 / 90

Advancing to step 4:
90 can be fit into 307 3 times, resulting in a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtract 270 from 307 to get 37.
Take the next digit (5) from the dividend and append it to 37, then repeat: 375 / 90

Going ahead to step 5:
The number 90 fits into 375 4 times, leaving a remainder of 15.
Record the quotient 4 as the next digit in the result. 
Result so far: 134.0
If we take 360 away from 375, we end up with 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 90

Let's proceed to step 6:
90 goes into 150 1 times with a remainder of 60.
Record the quotient 1 as the next digit in the result. 
Result so far: 1341.0
If we take 90 away from 150, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 7:
90 can be fit into 600 6 times, resulting in a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 1341.6
If we take 540 away from 600, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 8:
600 divided by 90 is 6 with a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 1341.66
Deduct 540 from 600 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Our division results in 1341.66 with a remaining 0.06.
