53517367 divided by 23 
The aim is to understand the frequency of 23 in 53517367.

Step 1:
If we divide 5 by 23, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 23

Going ahead to step 2:
23 can be fit into 53 2 times, resulting in a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 46 from 53 and we're left with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 23

Moving on to step 3:
When dividing 75 by 23, we get 3 with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
If we take 69 away from 75, we end up with 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 23

Advancing to step 4:
The number 23 fits into 61 2 times, leaving a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 232.0
Subtracting 46 from 61 leaves us with 15.
Fetch the next digit (7) from the dividend, attach it to 15 and continue: 157 / 23

On to step 5:
When dividing 157 by 23, we get 6 with a remainder of 19.
The number 6 becomes the next digit in our result. 
Result so far: 2326.0
Subtracting 138 from 157 leaves us with 19.
Append the next digit (3) from the dividend to 19 and continue with: 193 / 23

Let's proceed to step 6:
193 divided by 23 is 8 with a remainder of 9.
Put 8 as the next digit of the answer. 
Result so far: 23268.0
Subtract 184 from 193 to get 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 23

Going ahead to step 7:
When dividing 96 by 23, we get 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 232684.0
Subtracting 92 from 96 leaves us with 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 23

On to step 8:
If we divide 47 by 23, we get 2 and a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2326842.0
If we take 46 away from 47, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
10 divided by 23 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 2326842.0
Subtracting 0 from 10 leaves us with 10.
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 10:
100 divided by 23 is 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 2326842.04
If we take 92 away from 100, we end up 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 11:
23 goes into 80 3 times with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 2326842.043
Deduct 69 from 80 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 12:
110 divided by 23 is 4 with a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 2326842.0434
Subtract 92 from 110 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.

Moving on to step 13:
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: 2326842.04347
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.

Advancing to step 14:
If we divide 190 by 23, we get 8 and a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 2326842.043478
The remainder is 6 after subtracting 184 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 15:
60 divided by 23 is 2 with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 2326842.0434782
The remainder is 14 after subtracting 46 from 60.
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 16:
When dividing 140 by 23, we get 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 2326842.04347826
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.

The final outcome is 2326842.04347826, with a leftover of 2e-09.
