53525371 divided by 23 
The aim is to understand the frequency of 23 in 53525371.

Moving on to step 1:
If we divide 5 by 23, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 23

Moving on to step 2:
The number 23 fits into 53 2 times, leaving a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 7 after subtracting 46 from 53.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 23

Moving on to step 3:
75 divided by 23 is 3 with a remainder of 6.
The next digit of our result is 3. 
Result so far: 23.0
Deduct 69 from 75 and we're left with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 23

Moving on to step 4:
If we divide 62 by 23, we get 2 and a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 232.0
Subtract 46 from 62 to get 16.
Take the next digit (5) from the dividend and append it to 16, then repeat: 165 / 23

Advancing to step 5:
When dividing 165 by 23, we get 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 2327.0
Subtracting 161 from 165 leaves us with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 23

Let's proceed to step 6:
23 can be fit into 43 1 times, resulting in a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 23271.0
Deduct 23 from 43 and we're left with 20.
Include the next digit (7) from the dividend after 20, then repeat: 207 / 23

Moving on to step 7:
23 can be fit into 207 9 times, resulting in a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 232719.0
Subtracting 207 from 207 leaves us with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 23

Moving on to step 8:
1 divided by 23 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 2327190.0
Subtracting 0 from 1 leaves us 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.

Going ahead to step 9:
The number 23 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 2327190.0
Deduct 0 from 10 and we're left 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.

Going ahead to step 10:
23 goes into 100 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 2327190.04
If we subtract 92 from 100, we 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.

Moving on to step 11:
The number 23 fits into 80 3 times, leaving a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 2327190.043
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.

Step 12:
23 goes into 110 4 times with a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 2327190.0434
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 13:
23 goes into 180 7 times with a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 2327190.04347
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.

Let's proceed to step 14:
190 divided by 23 is 8 with a remainder of 6.
The next digit of our result is 8. 
Result so far: 2327190.043478
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.

Advancing to step 15:
23 can be fit into 60 2 times, resulting in a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 2327190.0434782
If we subtract 46 from 60, we get 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 16:
23 can be fit into 140 6 times, resulting in a remainder of 2.
The next digit of our result is 6. 
Result so far: 2327190.04347826
If we take 138 away from 140, we end up with 2.
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 2327190.04347826, with a leftover of 2e-09.
