54837081 divided by 23 
The aim is to understand the frequency of 23 in 54837081.

On to step 1:
When dividing 5 by 23, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 23

Going ahead to step 2:
54 divided by 23 is 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 46 away from 54, we end up with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 23

Advancing to step 3:
If we divide 88 by 23, we get 3 and a remainder of 19.
The next digit of our result is 3. 
Result so far: 23.0
Subtracting 69 from 88 leaves us with 19.
Fetch the next digit (3) from the dividend, attach it to 19 and continue: 193 / 23

On to step 4:
23 goes into 193 8 times with a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 238.0
Deduct 184 from 193 and we're left with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 23

Let's proceed to step 5:
If we divide 97 by 23, we get 4 and a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 2384.0
The remainder is 5 after subtracting 92 from 97.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 23

Moving on to step 6:
When dividing 50 by 23, we get 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 23842.0
If we subtract 46 from 50, we get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 23

On to step 7:
If we divide 48 by 23, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 238422.0
Deduct 46 from 48 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 23

Let's proceed to step 8:
The number 23 fits into 21 0 times, leaving a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 2384220.0
If we take 0 away from 21, we end up 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.

On to step 9:
When dividing 210 by 23, we get 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 2384220.9
Subtracting 207 from 210 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 10:
30 divided by 23 is 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 2384220.91
Subtracting 23 from 30 leaves us 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.

On to step 11:
23 goes into 70 3 times with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 2384220.913
Subtracting 69 from 70 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.

Let's proceed to step 12:
23 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 2384220.913
If we subtract 0 from 10, 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.

Let's proceed to step 13:
If we divide 100 by 23, we get 4 and a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 2384220.91304
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.

Let's proceed to step 14:
23 can be fit into 80 3 times, resulting in a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 2384220.913043
Subtracting 69 from 80 leaves us 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.

Moving on to step 15:
23 goes into 110 4 times with a remainder of 18.
The next digit of our result is 4. 
Result so far: 2384220.9130434
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.

Step 16:
23 can be fit into 180 7 times, resulting in a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 2384220.91304347
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.

The quotient of the division is 2384220.91304347, and the remainder is 1.9e-08.
