702420 divided by 12 
The aim is to understand the frequency of 12 in 702420.

On to step 1:
12 goes into 7 0 times with 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 (0) from the dividend and append it to 7, then repeat: 70 / 12

Going ahead to step 2:
If we divide 70 by 12, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 60 from 70 to get 10.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 12

Going ahead to step 3:
12 can be fit into 102 8 times, resulting in a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 58.0
Subtracting 96 from 102 leaves us with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 12

Going ahead to step 4:
When dividing 64 by 12, we get 5 with a remainder of 4.
The next digit of our result is 5. 
Result so far: 585.0
The remainder is 4 after subtracting 60 from 64.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 12

Going ahead to step 5:
The number 12 fits into 42 3 times, leaving a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 5853.0
Subtract 36 from 42 to get 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 12

Let's proceed to step 6:
When dividing 60 by 12, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 58535.0
If we take 60 away from 60, we end up 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.

Step 7:
When dividing 0 by 12, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 58535.0
If we take 0 away from 0, we end up 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.

On to step 8:
0 divided by 12 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 58535.0
If we take 0 away from 0, we end up 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.

In conclusion, the division gives 58535.0 with a balance of 0.0.
