We're dividing 613719 by 23 
The aim is to understand the frequency of 23 in 613719.

Let's proceed to step 1:
If we divide 6 by 23, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 23

Going ahead to step 2:
When dividing 61 by 23, we get 2 with a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 46 from 61 leaves us with 15.
Include the next digit (3) from the dividend after 15, then repeat: 153 / 23

On to step 3:
If we divide 153 by 23, we get 6 and a remainder of 15.
The next digit of our result is 6. 
Result so far: 26.0
Subtract 138 from 153 to get 15.
Append the next digit (7) from the dividend to 15 and continue with: 157 / 23

Advancing to step 4:
When dividing 157 by 23, we get 6 with a remainder of 19.
Write down 6 as next digit of the result. 
Result so far: 266.0
The remainder is 19 after subtracting 138 from 157.
Append the next digit (1) from the dividend to 19 and continue with: 191 / 23

Advancing to step 5:
191 divided by 23 is 8 with a remainder of 7.
The next digit of our result is 8. 
Result so far: 2668.0
The remainder is 7 after subtracting 184 from 191.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 23

Advancing to step 6:
The number 23 fits into 79 3 times, leaving a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 26683.0
If we subtract 69 from 79, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
100 divided by 23 is 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 26683.4
Deduct 92 from 100 and we're left 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.

On to step 8:
The number 23 fits into 80 3 times, leaving a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 26683.43
If we subtract 69 from 80, we 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.

Step 9:
23 can be fit into 110 4 times, resulting in a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 26683.434
If we subtract 92 from 110, we 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.

On to step 10:
When dividing 180 by 23, we get 7 with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 26683.4347
Subtracting 161 from 180 leaves us 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.

Advancing to step 11:
The number 23 fits into 190 8 times, leaving a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 26683.43478
If we subtract 184 from 190, we get 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 12:
If we divide 60 by 23, we get 2 and a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 26683.434782
Deduct 46 from 60 and we're left 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.

Let's proceed to step 13:
The number 23 fits into 140 6 times, leaving a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 26683.4347826
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.

Step 14:
The number 23 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 26683.4347826
Deduct 0 from 20 and we're left 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.

After the division, we end up with 26683.4347826 and a remainder of 2e-08.
