Let's divide 908317 by 12
The aim is to understand the frequency of 12 in 908317.

On to step 1:
9 divided by 12 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 12

Step 2:
The number 12 fits into 90 7 times, leaving a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 6 after subtracting 84 from 90.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 12

Let's proceed to step 3:
68 divided by 12 is 5 with a remainder of 8.
Write down 5 as next digit of the result. 
Result so far: 75.0
If we subtract 60 from 68, we get 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 12

On to step 4:
If we divide 83 by 12, we get 6 and a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 756.0
The remainder is 11 after subtracting 72 from 83.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 12

Step 5:
When dividing 111 by 12, we get 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 7569.0
Deduct 108 from 111 and we're left with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 12

Moving on to step 6:
37 divided by 12 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 75693.0
Subtracting 36 from 37 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
12 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 75693.0
If we take 0 away from 10, we end up 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.

Step 8:
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: 75693.08
If we subtract 96 from 100, 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.

Going ahead to step 9:
When dividing 40 by 12, we get 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 75693.083
If we take 36 away from 40, we end up 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.

Moving on to step 10:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 75693.0833
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.

After the division, we end up with 75693.0833 and a remainder of 4e-05.
