We're dividing 753856 by 12 
The aim is to understand the frequency of 12 in 753856.

Advancing to step 1:
The number 12 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 12

Step 2:
The number 12 fits into 75 6 times, leaving a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 72 away from 75, we end up with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 12

Going ahead to step 3:
If we divide 33 by 12, we get 2 and a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 62.0
If we subtract 24 from 33, we get 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 12

Moving on to step 4:
12 goes into 98 8 times with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 628.0
If we take 96 away from 98, we end up with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 12

Going ahead to step 5:
The number 12 fits into 25 2 times, leaving a remainder of 1.
The next digit of our result is 2. 
Result so far: 6282.0
If we subtract 24 from 25, we get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 12

Step 6:
16 divided by 12 is 1 with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 62821.0
If we take 12 away from 16, 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.

Step 7:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 62821.3
Deduct 36 from 40 and we're left 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 8:
40 divided by 12 is 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 62821.33
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.

The final result is 62821.33 with a remainder of 0.004.
