We look at the division of 783924 by 23 
The aim is to understand the frequency of 23 in 783924.

Let's proceed to step 1:
23 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 23

Let's proceed to step 2:
The number 23 fits into 78 3 times, leaving a remainder of 9.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 9 after subtracting 69 from 78.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 23

On to step 3:
If we divide 93 by 23, we get 4 and a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 34.0
Subtract 92 from 93 to get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 23

On to step 4:
The number 23 fits into 19 0 times, leaving a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 340.0
If we take 0 away from 19, we end up with 19.
Fetch the next digit (2) from the dividend, attach it to 19 and continue: 192 / 23

Going ahead to step 5:
If we divide 192 by 23, we get 8 and a remainder of 8.
The next digit of our result is 8. 
Result so far: 3408.0
Subtract 184 from 192 to get 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 23

Let's proceed to step 6:
84 divided by 23 is 3 with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 34083.0
If we take 69 away from 84, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
23 goes into 150 6 times with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 34083.6
Subtracting 138 from 150 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
If we divide 120 by 23, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 34083.65
Deduct 115 from 120 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 9:
If we divide 50 by 23, we get 2 and a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 34083.652
If we subtract 46 from 50, we get 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 10:
The number 23 fits into 40 1 times, leaving a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 34083.6521
If we subtract 23 from 40, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 11:
The number 23 fits into 170 7 times, leaving a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 34083.65217
The remainder is 9 after subtracting 161 from 170.
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 12:
The number 23 fits into 90 3 times, leaving a remainder of 21.
The next digit of our result is 3. 
Result so far: 34083.652173
Deduct 69 from 90 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 13:
210 divided by 23 is 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 34083.6521739
The remainder is 3 after subtracting 207 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 14:
23 goes into 30 1 times with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 34083.65217391
If we take 23 away from 30, we end up 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.

The quotient of the division is 34083.65217391, and the remainder is 7e-09.
