We look at the division of 747257 by 13 
The aim is to understand the frequency of 13 in 747257.

Let's proceed to step 1:
13 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 13

Moving on to step 2:
The number 13 fits into 74 5 times, leaving a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 9 after subtracting 65 from 74.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 13

Going ahead to step 3:
When dividing 97 by 13, we get 7 with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 57.0
If we take 91 away from 97, we end up with 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 13

Moving on to step 4:
When dividing 62 by 13, we get 4 with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 574.0
The remainder is 10 after subtracting 52 from 62.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 13

Advancing to step 5:
13 goes into 105 8 times with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 5748.0
Deduct 104 from 105 and we're left with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 13

Going ahead to step 6:
13 can be fit into 17 1 times, resulting in a remainder of 4.
The next digit of our result is 1. 
Result so far: 57481.0
Subtracting 13 from 17 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
13 can be fit into 40 3 times, resulting in a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 57481.3
Subtracting 39 from 40 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.

On to step 8:
13 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 57481.3
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.

Let's proceed to step 9:
If we divide 100 by 13, we get 7 and a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 57481.307
Subtracting 91 from 100 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 10:
13 goes into 90 6 times with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 57481.3076
If we subtract 78 from 90, we get 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 11:
The number 13 fits into 120 9 times, leaving a remainder of 3.
The next digit of our result is 9. 
Result so far: 57481.30769
Subtracting 117 from 120 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.

Going ahead to step 12:
30 divided by 13 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 57481.307692
If we subtract 26 from 30, 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.

Step 13:
The number 13 fits into 40 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 57481.3076923
Deduct 39 from 40 and we're left 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.

Step 14:
10 divided by 13 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 57481.3076923
If we take 0 away from 10, we end up 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.

The quotient of the division is 57481.3076923, and the remainder is 1e-08.
