We look at the division of 31112179 by 120 
Let's see how many times 120 fits into 31112179.

Moving on to step 1:
When dividing 3 by 120, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 120

Moving on to step 2:
When dividing 31 by 120, we get 0 with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Take the next digit (1) from the dividend and append it to 31, then repeat: 311 / 120

Advancing to step 3:
120 goes into 311 2 times with a remainder of 71.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 240 from 311 leaves us with 71.
Fetch the next digit (1) from the dividend, attach it to 71 and continue: 711 / 120

Going ahead to step 4:
711 divided by 120 is 5 with a remainder of 111.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Subtracting 600 from 711 leaves us with 111.
Grab the next digit (2) from the dividend, add it to 111, then carry on: 1112 / 120

Advancing to step 5:
If we divide 1112 by 120, we get 9 and a remainder of 32.
Use 9 as the next digit of our solution. 
Result so far: 259.0
Deduct 1080 from 1112 and we're left with 32.
Take the next digit (1) from the dividend and append it to 32, then repeat: 321 / 120

On to step 6:
The number 120 fits into 321 2 times, leaving a remainder of 81.
Use 2 as the next digit of our solution. 
Result so far: 2592.0
Deduct 240 from 321 and we're left with 81.
Take the next digit (7) from the dividend and append it to 81, then repeat: 817 / 120

Advancing to step 7:
The number 120 fits into 817 6 times, leaving a remainder of 97.
The number 6 becomes the next digit in our result. 
Result so far: 25926.0
If we take 720 away from 817, we end up with 97.
Bring next digit (9) of the dividend behind the 97 and repeat the process: 979 / 120

Going ahead to step 8:
979 divided by 120 is 8 with a remainder of 19.
Record the quotient 8 as the next digit in the result. 
Result so far: 259268.0
If we take 960 away from 979, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 9:
190 divided by 120 is 1 with a remainder of 70.
Put 1 as the next digit of the answer. 
Result so far: 259268.1
Subtract 120 from 190 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 10:
The number 120 fits into 700 5 times, leaving a remainder of 100.
Write down 5 as next digit of the result. 
Result so far: 259268.15
Deduct 600 from 700 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 11:
120 can be fit into 1000 8 times, resulting in a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 259268.158
Subtract 960 from 1000 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
120 can be fit into 400 3 times, resulting in a remainder of 40.
The next digit of our result is 3. 
Result so far: 259268.1583
If we take 360 away from 400, we end up 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.

On to step 13:
When dividing 400 by 120, we get 3 with a remainder of 40.
Use 3 as the next digit of our solution. 
Result so far: 259268.15833
Deduct 360 from 400 and we're left 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.

The final outcome is 259268.15833, with a leftover of 4e-05.
