We're dividing 310035 by 23 
The aim is to understand the frequency of 23 in 310035.

On to step 1:
When dividing 3 by 23, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 23

Advancing to step 2:
31 divided by 23 is 1 with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 23 away from 31, we end up with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 23

Step 3:
80 divided by 23 is 3 with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we subtract 69 from 80, we get 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 23

Advancing to step 4:
If we divide 110 by 23, we get 4 and a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 134.0
Deduct 92 from 110 and we're left with 18.
Include the next digit (3) from the dividend after 18, then repeat: 183 / 23

Going ahead to step 5:
When dividing 183 by 23, we get 7 with a remainder of 22.
Record the quotient 7 as the next digit in the result. 
Result so far: 1347.0
Subtract 161 from 183 to get 22.
Fetch the next digit (5) from the dividend, attach it to 22 and continue: 225 / 23

Going ahead to step 6:
23 goes into 225 9 times with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 13479.0
Subtract 207 from 225 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 7:
180 divided by 23 is 7 with a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 13479.7
If we take 161 away from 180, 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:
23 goes into 190 8 times with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 13479.78
Subtracting 184 from 190 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 9:
The number 23 fits into 60 2 times, leaving a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 13479.782
Subtracting 46 from 60 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 10:
When dividing 140 by 23, we get 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 13479.7826
If we subtract 138 from 140, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 11:
The number 23 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 13479.7826
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
The number 23 fits into 200 8 times, leaving a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 13479.782608
The remainder is 16 after subtracting 184 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
When dividing 160 by 23, we get 6 with a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 13479.7826086
Subtracting 138 from 160 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 14:
23 can be fit into 220 9 times, resulting in a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 13479.78260869
Deduct 207 from 220 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

In conclusion, the division gives 13479.78260869 with a balance of 1.3e-08.
