Let's divide 881606 by 12
The aim is to understand the frequency of 12 in 881606.

Let's proceed to step 1:
If we divide 8 by 12, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 12

On to step 2:
The number 12 fits into 88 7 times, leaving a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 84 from 88 to get 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 12

On to step 3:
When dividing 41 by 12, we get 3 with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 73.0
If we take 36 away from 41, we end up with 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 12

Moving on to step 4:
The number 12 fits into 56 4 times, leaving a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 734.0
Deduct 48 from 56 and we're left with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 12

Moving on to step 5:
80 divided by 12 is 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 7346.0
Deduct 72 from 80 and we're left with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 12

Going ahead to step 6:
If we divide 86 by 12, we get 7 and a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 73467.0
Subtract 84 from 86 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.

On to step 7:
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: 73467.1
If we take 12 away from 20, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 73467.16
Deduct 72 from 80 and we're left with 8.
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 9:
12 goes into 80 6 times with a remainder of 8.
The next digit of our result is 6. 
Result so far: 73467.166
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 73467.166 and a remainder of 0.0008.
