We divide 83218 by 12
The aim is to understand the frequency of 12 in 83218.

On to step 1:
12 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 12

Going ahead to step 2:
83 divided by 12 is 6 with a remainder of 11.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 11 after subtracting 72 from 83.
Append the next digit (2) from the dividend to 11 and continue with: 112 / 12

Advancing to step 3:
If we divide 112 by 12, we get 9 and a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 69.0
Subtracting 108 from 112 leaves us with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 12

Moving on to step 4:
12 can be fit into 41 3 times, resulting in a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 693.0
Subtracting 36 from 41 leaves us with 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 12

Step 5:
12 goes into 58 4 times with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 6934.0
Deduct 48 from 58 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 6:
When dividing 100 by 12, we get 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 6934.8
Subtracting 96 from 100 leaves us with 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:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 6934.83
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.

On to step 8:
When dividing 40 by 12, we get 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 6934.833
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.

The quotient of the division is 6934.833, and the remainder is 0.0004.
