235248 divided by 31 
The aim is to understand the frequency of 31 in 235248.

Moving on to step 1:
31 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 31

Moving on to step 2:
31 goes into 23 0 times with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Grab the next digit (5) from the dividend, add it to 23, then carry on: 235 / 31

Advancing to step 3:
31 goes into 235 7 times with a remainder of 18.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 217 from 235, we get 18.
Fetch the next digit (2) from the dividend, attach it to 18 and continue: 182 / 31

Let's proceed to step 4:
182 divided by 31 is 5 with a remainder of 27.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
Subtracting 155 from 182 leaves us with 27.
Include the next digit (4) from the dividend after 27, then repeat: 274 / 31

Step 5:
If we divide 274 by 31, we get 8 and a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 758.0
Deduct 248 from 274 and we're left with 26.
Take the next digit (8) from the dividend and append it to 26, then repeat: 268 / 31

Advancing to step 6:
31 can be fit into 268 8 times, resulting in a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 7588.0
Subtracting 248 from 268 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 7:
The number 31 fits into 200 6 times, leaving a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 7588.6
If we subtract 186 from 200, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
31 can be fit into 140 4 times, resulting in a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 7588.64
Subtract 124 from 140 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
The number 31 fits into 160 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 7588.645
Subtract 155 from 160 to 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 10:
50 divided by 31 is 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 7588.6451
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.

Going ahead to step 11:
If we divide 190 by 31, we get 6 and a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 7588.64516
Subtracting 186 from 190 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.

Moving on to step 12:
The number 31 fits into 40 1 times, leaving a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 7588.645161
Subtract 31 from 40 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 13:
90 divided by 31 is 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 7588.6451612
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.

On to step 14:
If we divide 280 by 31, we get 9 and a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 7588.64516129
If we subtract 279 from 280, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 7588.64516129 with a balance of 1e-09.
