We divide 802870 by 12
The aim is to understand the frequency of 12 in 802870.

Step 1:
12 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 12

Step 2:
When dividing 80 by 12, we get 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 72 from 80 to get 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 12

Moving on to step 3:
If we divide 82 by 12, we get 6 and a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 66.0
If we take 72 away from 82, we end up with 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 12

Step 4:
When dividing 108 by 12, we get 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 669.0
If we take 108 away from 108, we end up with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 12

Advancing to step 5:
When dividing 7 by 12, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 6690.0
If we subtract 0 from 7, we get 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 12

Let's proceed to step 6:
When dividing 70 by 12, we get 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 66905.0
If we subtract 60 from 70, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
12 goes into 100 8 times with a remainder of 4.
The next digit of our result is 8. 
Result so far: 66905.8
If we take 96 away from 100, 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 8:
12 can be fit into 40 3 times, resulting in a remainder of 4.
The next digit of our result is 3. 
Result so far: 66905.83
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.

On to step 9:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 66905.833
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.

The final outcome is 66905.833, with a leftover of 0.0004.
