We're dividing 873241 by 12 
The aim is to understand the frequency of 12 in 873241.

Moving on to step 1:
The number 12 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 12

Advancing to step 2:
The number 12 fits into 87 7 times, leaving a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 3 after subtracting 84 from 87.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 12

Let's proceed to step 3:
12 goes into 33 2 times with a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 72.0
Subtract 24 from 33 to get 9.
Bring next digit (2) of the dividend behind the 9 and repeat the process: 92 / 12

Going ahead to step 4:
If we divide 92 by 12, we get 7 and a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 727.0
If we take 84 away from 92, we end up with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 12

On to step 5:
The number 12 fits into 84 7 times, leaving a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 7277.0
Subtract 84 from 84 to get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 12

On to step 6:
12 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 72770.0
Subtract 0 from 1 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
12 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 72770.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
12 goes into 100 8 times with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 72770.08
If we subtract 96 from 100, 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.

Moving on to step 9:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 72770.083
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
40 divided by 12 is 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 72770.0833
If we take 36 away from 40, 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.

The final outcome is 72770.0833, with a leftover of 4e-05.
