We divide 69377 by 13
The aim is to understand the frequency of 13 in 69377.

Let's proceed to step 1:
6 divided by 13 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 13

On to step 2:
The number 13 fits into 69 5 times, leaving a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 65 from 69 leaves us with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 13

Advancing to step 3:
When dividing 43 by 13, we get 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 53.0
If we take 39 away from 43, we end up with 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 13

Let's proceed to step 4:
If we divide 47 by 13, we get 3 and a remainder of 8.
The next digit of our result is 3. 
Result so far: 533.0
The remainder is 8 after subtracting 39 from 47.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 13

Going ahead to step 5:
13 goes into 87 6 times with a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 5336.0
Deduct 78 from 87 and we're left 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.

Moving on to step 6:
13 goes into 90 6 times with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 5336.6
If we take 78 away from 90, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 7:
13 goes into 120 9 times with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 5336.69
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.

Advancing to step 8:
13 can be fit into 30 2 times, resulting in a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 5336.692
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.

Going ahead to step 9:
13 goes into 40 3 times with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 5336.6923
Subtract 39 from 40 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing 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: 5336.6923
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.

Going ahead to step 11:
100 divided by 13 is 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 5336.692307
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.

Let's proceed to step 12:
13 can be fit into 90 6 times, resulting in a remainder of 12.
The next digit of our result is 6. 
Result so far: 5336.6923076
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.

Advancing to step 13:
13 can be fit into 120 9 times, resulting in a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 5336.69230769
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.

The final outcome is 5336.69230769, with a leftover of 3e-09.
