We divide 981712 by 12
The aim is to understand the frequency of 12 in 981712.

Step 1:
When dividing 9 by 12, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 12

Let's proceed to step 2:
98 divided by 12 is 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 2 after subtracting 96 from 98.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 12

Advancing to step 3:
12 goes into 21 1 times with a remainder of 9.
The next digit of our result is 1. 
Result so far: 81.0
Deduct 12 from 21 and we're left with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 12

Advancing to step 4:
The number 12 fits into 97 8 times, leaving a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 818.0
The remainder is 1 after subtracting 96 from 97.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 12

On to step 5:
The number 12 fits into 11 0 times, leaving a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 8180.0
If we subtract 0 from 11, we get 11.
Fetch the next digit (2) from the dividend, attach it to 11 and continue: 112 / 12

On to step 6:
112 divided by 12 is 9 with a remainder of 4.
The next digit of our result is 9. 
Result so far: 81809.0
If we subtract 108 from 112, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
If we divide 40 by 12, we get 3 and a remainder of 4.
The next digit of our result is 3. 
Result so far: 81809.3
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
12 goes into 40 3 times with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 81809.33
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 81809.33 with a remaining 0.004.
