456160 ÷ 12 
The aim is to understand the frequency of 12 in 456160.

On to step 1:
The number 12 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 12

Going ahead to step 2:
12 can be fit into 45 3 times, resulting in a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 36 from 45 to get 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 12

Going ahead to step 3:
12 can be fit into 96 8 times, resulting in a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
Subtracting 96 from 96 leaves us with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 12

Going ahead to step 4:
When dividing 1 by 12, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 380.0
If we subtract 0 from 1, we get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 12

Going ahead to step 5:
If we divide 16 by 12, we get 1 and a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 3801.0
If we subtract 12 from 16, we get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 12

Step 6:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 38013.0
Deduct 36 from 40 and we're left 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.

Going ahead to step 7:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 38013.3
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.

Going ahead to step 8:
12 goes into 40 3 times with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 38013.33
Subtract 36 from 40 to 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.

The quotient of the division is 38013.33, and the remainder is 0.004.
