254129 ÷ 31 
The aim is to understand the frequency of 31 in 254129.

Advancing to step 1:
If we divide 2 by 31, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 31

Let's proceed to step 2:
31 goes into 25 0 times with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Bring next digit (4) of the dividend behind the 25 and repeat the process: 254 / 31

Step 3:
31 goes into 254 8 times with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 248 from 254 to get 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 31

Advancing to step 4:
31 goes into 61 1 times with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
If we subtract 31 from 61, we get 30.
Grab the next digit (2) from the dividend, add it to 30, then carry on: 302 / 31

Step 5:
When dividing 302 by 31, we get 9 with a remainder of 23.
The next digit of our result is 9. 
Result so far: 819.0
If we subtract 279 from 302, we get 23.
Take the next digit (9) from the dividend and append it to 23, then repeat: 239 / 31

Let's proceed to step 6:
31 can be fit into 239 7 times, resulting in a remainder of 22.
Record the quotient 7 as the next digit in the result. 
Result so far: 8197.0
The remainder is 22 after subtracting 217 from 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 7:
When dividing 220 by 31, we get 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 8197.7
Deduct 217 from 220 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 8:
The number 31 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 8197.7
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 9:
When dividing 300 by 31, we get 9 with a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 8197.709
Subtracting 279 from 300 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 10:
When dividing 210 by 31, we get 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 8197.7096
Subtracting 186 from 210 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 11:
240 divided by 31 is 7 with a remainder of 23.
The next digit of our result is 7. 
Result so far: 8197.70967
If we take 217 away from 240, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 12:
If we divide 230 by 31, we get 7 and a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 8197.709677
If we subtract 217 from 230, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final outcome is 8197.709677, with a leftover of 1.3e-06.
