We're dividing 749820 by 12 
The aim is to understand the frequency of 12 in 749820.

Step 1:
The number 12 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 12

Going ahead to step 2:
12 can be fit into 74 6 times, resulting in a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 72 from 74 leaves us with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 12

Going ahead to step 3:
When dividing 29 by 12, we get 2 with a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 62.0
If we take 24 away from 29, we end up with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 12

Step 4:
If we divide 58 by 12, we get 4 and a remainder of 10.
The next digit of our result is 4. 
Result so far: 624.0
If we take 48 away from 58, we end up with 10.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 12

Advancing to step 5:
If we divide 102 by 12, we get 8 and a remainder of 6.
The next digit of our result is 8. 
Result so far: 6248.0
Subtract 96 from 102 to get 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 12

Advancing to step 6:
The number 12 fits into 60 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 62485.0
If we subtract 60 from 60, 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 7:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 62485.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
If we divide 0 by 12, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 62485.0
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.

The final result is 62485.0 with a remainder of 0.0.
