Let's divide 31142758 by 120
Let's see how many times 120 fits into 31142758.

Advancing to step 1:
120 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 120

On to step 2:
The number 120 fits into 31 0 times, leaving a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Grab the next digit (1) from the dividend, add it to 31, then carry on: 311 / 120

Step 3:
311 divided by 120 is 2 with a remainder of 71.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 240 from 311, we get 71.
Fetch the next digit (4) from the dividend, attach it to 71 and continue: 714 / 120

Let's proceed to step 4:
120 goes into 714 5 times with a remainder of 114.
Use 5 as the next digit of our solution. 
Result so far: 25.0
If we take 600 away from 714, we end up with 114.
Bring next digit (2) of the dividend behind the 114 and repeat the process: 1142 / 120

Let's proceed to step 5:
1142 divided by 120 is 9 with a remainder of 62.
Use 9 as the next digit of our solution. 
Result so far: 259.0
Subtracting 1080 from 1142 leaves us with 62.
Fetch the next digit (7) from the dividend, attach it to 62 and continue: 627 / 120

Moving on to step 6:
If we divide 627 by 120, we get 5 and a remainder of 27.
Put 5 as the next digit of the answer. 
Result so far: 2595.0
The remainder is 27 after subtracting 600 from 627.
Grab the next digit (5) from the dividend, add it to 27, then carry on: 275 / 120

Advancing to step 7:
The number 120 fits into 275 2 times, leaving a remainder of 35.
Put 2 as the next digit of the answer. 
Result so far: 25952.0
If we take 240 away from 275, we end up with 35.
Fetch the next digit (8) from the dividend, attach it to 35 and continue: 358 / 120

Going ahead to step 8:
When dividing 358 by 120, we get 2 with a remainder of 118.
Use 2 as the next digit of our solution. 
Result so far: 259522.0
Subtract 240 from 358 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Advancing to step 9:
If we divide 1180 by 120, we get 9 and a remainder of 100.
The number 9 becomes the next digit in our result. 
Result so far: 259522.9
If we take 1080 away from 1180, we end up 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.

Advancing to step 10:
120 can be fit into 1000 8 times, resulting in a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 259522.98
The remainder is 40 after subtracting 960 from 1000.
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 11:
400 divided by 120 is 3 with a remainder of 40.
The next digit of our result is 3. 
Result so far: 259522.983
If we subtract 360 from 400, we 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 number 3 becomes the next digit in our result. 
Result so far: 259522.9833
Subtracting 360 from 400 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.

The final outcome is 259522.9833, with a leftover of 0.0004.
