We're dividing 140931 by 12 
The aim is to understand the frequency of 12 in 140931.

On to step 1:
12 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 12

Advancing to step 2:
The number 12 fits into 14 1 times, leaving a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 2 after subtracting 12 from 14.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 12

On to step 3:
20 divided by 12 is 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 12 from 20, we get 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 12

Going ahead to step 4:
12 can be fit into 89 7 times, resulting in a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 117.0
Subtract 84 from 89 to get 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 12

Going ahead to step 5:
12 can be fit into 53 4 times, resulting in a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 1174.0
Deduct 48 from 53 and we're left with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 12

Moving on to step 6:
12 can be fit into 51 4 times, resulting in a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 11744.0
The remainder is 3 after subtracting 48 from 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
12 goes into 30 2 times with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 11744.2
If we take 24 away from 30, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
When dividing 60 by 12, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 11744.25
The remainder is 0 after subtracting 60 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
When dividing 0 by 12, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 11744.25
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
12 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 11744.25
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 11744.25 with a remainder of 0.0.
