We divide 802943 by 12
The aim is to understand the frequency of 12 in 802943.

Moving on to step 1:
12 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 12

Advancing to step 2:
12 goes into 80 6 times with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 72 from 80 to get 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 12

Going ahead to step 3:
The number 12 fits into 82 6 times, leaving a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 66.0
If we take 72 away from 82, we end up with 10.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 12

On to step 4:
12 can be fit into 109 9 times, resulting in a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 669.0
Subtract 108 from 109 to get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 12

Moving on to step 5:
If we divide 14 by 12, we get 1 and a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 6691.0
If we subtract 12 from 14, we get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 12

Moving on to step 6:
12 goes into 23 1 times with a remainder of 11.
The next digit of our result is 1. 
Result so far: 66911.0
Deduct 12 from 23 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
12 goes into 110 9 times with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 66911.9
Deduct 108 from 110 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
When dividing 20 by 12, we get 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 66911.91
Subtracting 12 from 20 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
80 divided by 12 is 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 66911.916
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
The number 12 fits into 80 6 times, leaving a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 66911.9166
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 66911.9166 with a remaining 8e-05.
