We're dividing 344415 by 31 
The aim is to understand the frequency of 31 in 344415.

Step 1:
31 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 31

Step 2:
31 can be fit into 34 1 times, resulting in a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 31 from 34 leaves us with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 31

Going ahead to step 3:
31 goes into 34 1 times with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 31 away from 34, we end up with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 31

Let's proceed to step 4:
The number 31 fits into 34 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 111.0
Deduct 31 from 34 and we're left with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 31

Step 5:
If we divide 31 by 31, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1111.0
Deduct 31 from 31 and we're left with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 31

Moving on to step 6:
When dividing 5 by 31, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 11110.0
Deduct 0 from 5 and we're left 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.

Going ahead to step 7:
50 divided by 31 is 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 11110.1
If we take 31 away from 50, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 8:
If we divide 190 by 31, we get 6 and a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 11110.16
Deduct 186 from 190 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.

Let's proceed to step 9:
When dividing 40 by 31, we get 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 11110.161
The remainder is 9 after subtracting 31 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 10:
When dividing 90 by 31, we get 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 11110.1612
Deduct 62 from 90 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 11:
31 goes into 280 9 times with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 11110.16129
If we take 279 away from 280, we end up 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.

Step 12:
If we divide 10 by 31, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 11110.16129
If we subtract 0 from 10, we 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.

Moving on to step 13:
The number 31 fits into 100 3 times, leaving a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 11110.1612903
If we take 93 away from 100, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 14:
When dividing 70 by 31, we get 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 11110.16129032
The remainder is 8 after subtracting 62 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 11110.16129032, and the remainder is 8e-09.
