128633 ÷ 12 
The aim is to understand the frequency of 12 in 128633.

Advancing to step 1:
1 divided by 12 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 12

Step 2:
If we divide 12 by 12, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 12 from 12 to get 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 12

Advancing to step 3:
12 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 12

Going ahead to step 4:
When dividing 86 by 12, we get 7 with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 107.0
Deduct 84 from 86 and we're left with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 12

Advancing to step 5:
When dividing 23 by 12, we get 1 with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 1071.0
If we take 12 away from 23, we end up with 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 12

Moving on to step 6:
12 goes into 113 9 times with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 10719.0
Subtracting 108 from 113 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
If we divide 50 by 12, we get 4 and a remainder of 2.
The next digit of our result is 4. 
Result so far: 10719.4
Subtract 48 from 50 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
The number 12 fits into 20 1 times, leaving a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 10719.41
If we subtract 12 from 20, we 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.

Step 9:
80 divided by 12 is 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 10719.416
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
The number 12 fits into 80 6 times, leaving a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 10719.4166
The remainder is 8 after subtracting 72 from 80.
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 10719.4166 with a remaining 8e-05.
