872184 divided by 12 
The aim is to understand the frequency of 12 in 872184.

Step 1:
If we divide 8 by 12, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 12

Let's proceed to step 2:
When dividing 87 by 12, we get 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 84 from 87 to get 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 12

Going ahead to step 3:
The number 12 fits into 32 2 times, leaving a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 72.0
Deduct 24 from 32 and we're left with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 12

Let's proceed to step 4:
12 goes into 81 6 times with a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 726.0
If we subtract 72 from 81, we get 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 12

On to step 5:
If we divide 98 by 12, we get 8 and a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 7268.0
Deduct 96 from 98 and we're left with 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 12

Moving on to step 6:
12 goes into 24 2 times with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 72682.0
If we subtract 24 from 24, 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.

Step 7:
If we divide 0 by 12, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 72682.0
Subtract 0 from 0 to 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.

Moving on to step 8:
0 divided by 12 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 72682.0
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.

The quotient of the division is 72682.0, and the remainder is 0.0.
