54917297 ÷ 13 
The aim is to understand the frequency of 13 in 54917297.

On to step 1:
13 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 13

Going ahead to step 2:
13 goes into 54 4 times with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 52 away from 54, we end up with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 13

Let's proceed to step 3:
13 goes into 29 2 times with a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Deduct 26 from 29 and we're left with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 13

On to step 4:
13 can be fit into 31 2 times, resulting in a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 422.0
Subtract 26 from 31 to get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 13

Advancing to step 5:
57 divided by 13 is 4 with a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 4224.0
Subtract 52 from 57 to get 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 13

Advancing to step 6:
When dividing 52 by 13, we get 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 42244.0
If we take 52 away from 52, we end up with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 13

On to step 7:
13 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 422440.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 13

Moving on to step 8:
The number 13 fits into 97 7 times, leaving a remainder of 6.
The next digit of our result is 7. 
Result so far: 4224407.0
If we subtract 91 from 97, 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.

Step 9:
13 goes into 60 4 times with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 4224407.4
The remainder is 8 after subtracting 52 from 60.
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 10:
When dividing 80 by 13, we get 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 4224407.46
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 11:
13 goes into 20 1 times with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 4224407.461
If we subtract 13 from 20, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 12:
If we divide 70 by 13, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 4224407.4615
The remainder is 5 after subtracting 65 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 13:
50 divided by 13 is 3 with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 4224407.46153
If we take 39 away from 50, we end up 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 14:
13 can be fit into 110 8 times, resulting in a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 4224407.461538
The remainder is 6 after subtracting 104 from 110.
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 15:
13 can be fit into 60 4 times, resulting in a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 4224407.4615384
If we take 52 away from 60, 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.

Advancing to step 16:
13 goes into 80 6 times with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 4224407.46153846
If we subtract 78 from 80, we get 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 result is 4224407.46153846 with a remainder of 2e-09.
