We look at the division of 534377 by 13 
The aim is to understand the frequency of 13 in 534377.

Moving on to step 1:
If we divide 5 by 13, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 13

Moving on to step 2:
13 goes into 53 4 times with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 1 after subtracting 52 from 53.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 13

On to step 3:
If we divide 14 by 13, we get 1 and a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 41.0
Deduct 13 from 14 and we're left with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 13

On to step 4:
If we divide 13 by 13, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 411.0
If we subtract 13 from 13, we get 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 13

Moving on to step 5:
13 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 4110.0
If we take 0 away from 7, we end up with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 13

Step 6:
If we divide 77 by 13, we get 5 and a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 41105.0
Subtract 65 from 77 to 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.

Advancing to step 7:
13 goes into 120 9 times with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 41105.9
If we subtract 117 from 120, we get 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 8:
The number 13 fits into 30 2 times, leaving a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 41105.92
Subtract 26 from 30 to 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 9:
40 divided by 13 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 41105.923
The remainder is 1 after subtracting 39 from 40.
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 10:
13 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 41105.923
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.

Step 11:
13 can be fit into 100 7 times, resulting in a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 41105.92307
Subtract 91 from 100 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 12:
13 goes into 90 6 times with a remainder of 12.
The next digit of our result is 6. 
Result so far: 41105.923076
The remainder is 12 after subtracting 78 from 90.
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 13:
13 can be fit into 120 9 times, resulting in a remainder of 3.
The next digit of our result is 9. 
Result so far: 41105.9230769
Subtract 117 from 120 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 14:
When dividing 30 by 13, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 41105.92307692
The remainder is 4 after subtracting 26 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 41105.92307692, and the remainder is 4e-09.
