8787376 ÷ 12 
The aim is to understand the frequency of 12 in 8787376.

Going ahead to step 1:
If we divide 8 by 12, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 12

Step 2:
When dividing 87 by 12, we get 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 84 from 87 to get 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 12

On to step 3:
38 divided by 12 is 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 73.0
The remainder is 2 after subtracting 36 from 38.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 12

On to step 4:
The number 12 fits into 27 2 times, leaving a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 732.0
Subtracting 24 from 27 leaves us with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 12

Moving on to step 5:
33 divided by 12 is 2 with a remainder of 9.
The next digit of our result is 2. 
Result so far: 7322.0
Subtract 24 from 33 to get 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 12

Moving on to step 6:
When dividing 97 by 12, we get 8 with a remainder of 1.
The next digit of our result is 8. 
Result so far: 73228.0
If we take 96 away from 97, we end up with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 12

Advancing to step 7:
If we divide 16 by 12, we get 1 and a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 732281.0
If we take 12 away from 16, 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:
When dividing 40 by 12, we get 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 732281.3
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.

Advancing to step 9:
12 goes into 40 3 times with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 732281.33
Subtracting 36 from 40 leaves us 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 quotient of the division is 732281.33, and the remainder is 0.004.
