51697 ÷ 12 
The aim is to understand the frequency of 12 in 51697.

Advancing to step 1:
12 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 12

Let's proceed to step 2:
12 can be fit into 51 4 times, resulting in a remainder of 3.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 48 from 51 to get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 12

Advancing to step 3:
12 can be fit into 36 3 times, resulting in a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 43.0
Subtract 36 from 36 to get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 12

Advancing to step 4:
The number 12 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 430.0
If we subtract 0 from 9, we get 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 12

Going ahead to step 5:
12 goes into 97 8 times with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 4308.0
Subtracting 96 from 97 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 6:
When dividing 10 by 12, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 4308.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
12 can be fit into 100 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 4308.08
Subtracting 96 from 100 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.

Advancing to step 8:
40 divided by 12 is 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 4308.083
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.

Advancing to step 9:
40 divided by 12 is 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 4308.0833
If we take 36 away from 40, 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.

After the division, we end up with 4308.0833 and a remainder of 4e-05.
