883290 divided by 12 
The aim is to understand the frequency of 12 in 883290.

On to step 1:
8 divided by 12 is 0 with 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.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 12

Let's proceed to step 2:
If we divide 88 by 12, we get 7 and a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 4 after subtracting 84 from 88.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 12

Advancing to step 3:
43 divided by 12 is 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 73.0
Deduct 36 from 43 and we're left with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 12

Advancing to step 4:
When dividing 72 by 12, we get 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 736.0
The remainder is 0 after subtracting 72 from 72.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 12

Advancing to step 5:
When dividing 9 by 12, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 7360.0
Subtract 0 from 9 to get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 12

Moving on to step 6:
When dividing 90 by 12, we get 7 with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 73607.0
The remainder is 6 after subtracting 84 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
60 divided by 12 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 73607.5
The remainder is 0 after subtracting 60 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
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: 73607.5
Subtracting 0 from 0 leaves us 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.

On to step 9:
0 divided by 12 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 73607.5
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 final result is 73607.5 with a remainder of 0.0.
