131427 ÷ 1 
The aim is to understand the frequency of 1 in 131427.

Step 1:
1 can be fit into 1 1 times, resulting in a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 1 from 1 to get 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 1

Moving on to step 2:
When dividing 3 by 1, we get 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 13.0
The remainder is 0 after subtracting 3 from 3.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 1

Step 3:
1 can be fit into 1 1 times, resulting in a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 131.0
The remainder is 0 after subtracting 1 from 1.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 1

Let's proceed to step 4:
4 divided by 1 is 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 1314.0
Subtract 4 from 4 to get 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 1

Moving on to step 5:
1 can be fit into 2 2 times, resulting in a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 13142.0
The remainder is 0 after subtracting 2 from 2.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 1

Advancing to step 6:
1 goes into 7 7 times with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 131427.0
Subtracting 7 from 7 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.

Step 7:
If we divide 0 by 1, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 131427.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 131427.0
Deduct 0 from 0 and we're left 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 quotient of the division is 131427.0, and the remainder is 0.0.
