We look at the division of 742341 by 12 
The aim is to understand the frequency of 12 in 742341.

Moving on 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
Subtract 0 from 7 to get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 12

Step 2:
If we divide 74 by 12, we get 6 and a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 72 from 74, we get 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 12

On to step 3:
22 divided by 12 is 1 with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 61.0
If we take 12 away from 22, we end up with 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 12

Step 4:
When dividing 103 by 12, we get 8 with a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 618.0
Subtract 96 from 103 to get 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 12

Step 5:
12 can be fit into 74 6 times, resulting in a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 6186.0
Subtracting 72 from 74 leaves us with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 12

On to step 6:
21 divided by 12 is 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 61861.0
If we take 12 away from 21, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
12 goes into 90 7 times with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 61861.7
Subtract 84 from 90 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
60 divided by 12 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 61861.75
Subtracting 60 from 60 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
If we divide 0 by 12, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 61861.75
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
12 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 61861.75
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 61861.75 with a remaining 0.0.
