920636 ÷ 12 
The aim is to understand the frequency of 12 in 920636.

Advancing to step 1:
9 divided by 12 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (2) of the dividend behind the 9 and repeat the process: 92 / 12

Going ahead to step 2:
12 goes into 92 7 times with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 84 from 92, we get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 12

Moving on to step 3:
12 goes into 80 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 76.0
Deduct 72 from 80 and we're left with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 12

Let's proceed to step 4:
86 divided by 12 is 7 with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 767.0
If we subtract 84 from 86, we get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 12

Moving on to step 5:
The number 12 fits into 23 1 times, leaving a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 7671.0
The remainder is 11 after subtracting 12 from 23.
Grab the next digit (6) from the dividend, add it to 11, then carry on: 116 / 12

Let's proceed to step 6:
12 goes into 116 9 times with a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 76719.0
If we subtract 108 from 116, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
80 divided by 12 is 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 76719.6
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
12 goes into 80 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 76719.66
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 76719.66 and a remainder of 0.008.
