We look at the division of 120012 by 89 
Our goal is to divide 120012 by 89.

Let's proceed to step 1:
89 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 89

Moving on to step 2:
If we divide 12 by 89, we get 0 and a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 89

Moving on to step 3:
The number 89 fits into 120 1 times, leaving a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 89 from 120 and we're left with 31.
Take the next digit (0) from the dividend and append it to 31, then repeat: 310 / 89

Advancing to step 4:
89 goes into 310 3 times with a remainder of 43.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 43 after subtracting 267 from 310.
Take the next digit (1) from the dividend and append it to 43, then repeat: 431 / 89

On to step 5:
431 divided by 89 is 4 with a remainder of 75.
The next digit of our result is 4. 
Result so far: 134.0
Subtract 356 from 431 to get 75.
Take the next digit (2) from the dividend and append it to 75, then repeat: 752 / 89

On to step 6:
The number 89 fits into 752 8 times, leaving a remainder of 40.
The next digit of our result is 8. 
Result so far: 1348.0
Subtracting 712 from 752 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 7:
When dividing 400 by 89, we get 4 with a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 1348.4
Deduct 356 from 400 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 8:
If we divide 440 by 89, we get 4 and a remainder of 84.
The number 4 becomes the next digit in our result. 
Result so far: 1348.44
The remainder is 84 after subtracting 356 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The quotient of the division is 1348.44, and the remainder is 0.084.
