126330 ÷ 90 
We want to figure out the number of times 126330 can be divided by 90.

Moving on to step 1:
When dividing 1 by 90, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 90

On to step 2:
12 divided by 90 is 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Bring next digit (6) of the dividend behind the 12 and repeat the process: 126 / 90

Moving on to step 3:
90 goes into 126 1 times with a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 90 from 126 and we're left with 36.
Take the next digit (3) from the dividend and append it to 36, then repeat: 363 / 90

Going ahead to step 4:
90 goes into 363 4 times with a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 14.0
The remainder is 3 after subtracting 360 from 363.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 90

Advancing to step 5:
33 divided by 90 is 0 with a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 140.0
Subtracting 0 from 33 leaves us with 33.
Take the next digit (0) from the dividend and append it to 33, then repeat: 330 / 90

Moving on to step 6:
The number 90 fits into 330 3 times, leaving a remainder of 60.
Use 3 as the next digit of our solution. 
Result so far: 1403.0
If we subtract 270 from 330, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 7:
When dividing 600 by 90, we get 6 with a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 1403.6
If we subtract 540 from 600, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
The number 90 fits into 600 6 times, leaving a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 1403.66
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.

After the division, we end up with 1403.66 and a remainder of 0.06.
