We're dividing 929137 by 31 
The aim is to understand the frequency of 31 in 929137.

Moving on to step 1:
The number 31 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 31

On to step 2:
31 can be fit into 92 2 times, resulting in a remainder of 30.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 62 from 92 leaves us with 30.
Include the next digit (9) from the dividend after 30, then repeat: 309 / 31

Moving on to step 3:
When dividing 309 by 31, we get 9 with a remainder of 30.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
Subtracting 279 from 309 leaves us with 30.
Include the next digit (1) from the dividend after 30, then repeat: 301 / 31

Moving on to step 4:
When dividing 301 by 31, we get 9 with a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 299.0
Subtracting 279 from 301 leaves us with 22.
Take the next digit (3) from the dividend and append it to 22, then repeat: 223 / 31

Going ahead to step 5:
The number 31 fits into 223 7 times, leaving a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 2997.0
Deduct 217 from 223 and we're left with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 31

Moving on to step 6:
31 goes into 67 2 times with a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 29972.0
If we subtract 62 from 67, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
The number 31 fits into 50 1 times, leaving a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 29972.1
If we subtract 31 from 50, we get 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:
The number 31 fits into 190 6 times, leaving a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 29972.16
The remainder is 4 after subtracting 186 from 190.
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:
31 goes into 40 1 times with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 29972.161
If we take 31 away from 40, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 10:
When dividing 90 by 31, we get 2 with a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 29972.1612
Subtract 62 from 90 to get 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:
When dividing 280 by 31, we get 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 29972.16129
Subtracting 279 from 280 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.

On to step 12:
The number 31 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 29972.16129
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
100 divided by 31 is 3 with a remainder of 7.
The next digit of our result is 3. 
Result so far: 29972.1612903
Deduct 93 from 100 and we're left 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.

Advancing to step 14:
The number 31 fits into 70 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 29972.16129032
If we take 62 away from 70, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 29972.16129032 with a balance of 8e-09.
