Let's divide 404235 by 23
The aim is to understand the frequency of 23 in 404235.

On to step 1:
The number 23 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 23

Advancing to step 2:
23 can be fit into 40 1 times, resulting in a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 23 away from 40, we end up with 17.
Append the next digit (4) from the dividend to 17 and continue with: 174 / 23

Moving on to step 3:
174 divided by 23 is 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Deduct 161 from 174 and we're left with 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 23

Moving on to step 4:
If we divide 132 by 23, we get 5 and a remainder of 17.
The next digit of our result is 5. 
Result so far: 175.0
If we subtract 115 from 132, we get 17.
Fetch the next digit (3) from the dividend, attach it to 17 and continue: 173 / 23

On to step 5:
When dividing 173 by 23, we get 7 with a remainder of 12.
The next digit of our result is 7. 
Result so far: 1757.0
If we take 161 away from 173, we end up with 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 23

Moving on to step 6:
125 divided by 23 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 17575.0
The remainder is 10 after subtracting 115 from 125.
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 7:
100 divided by 23 is 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 17575.4
Subtract 92 from 100 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
23 goes into 80 3 times with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 17575.43
Subtract 69 from 80 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
110 divided by 23 is 4 with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 17575.434
If we take 92 away from 110, we end up with 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 10:
If we divide 180 by 23, we get 7 and a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 17575.4347
The remainder is 19 after subtracting 161 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 11:
190 divided by 23 is 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 17575.43478
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.

On to step 12:
60 divided by 23 is 2 with a remainder of 14.
The next digit of our result is 2. 
Result so far: 17575.434782
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.

Going ahead to step 13:
140 divided by 23 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 17575.4347826
The remainder is 2 after subtracting 138 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 14:
The number 23 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 17575.4347826
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 17575.4347826, and the remainder is 2e-08.
