We're dividing 755592 by 13 
The aim is to understand the frequency of 13 in 755592.

Going ahead to step 1:
13 goes into 7 0 times with 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.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 13

Step 2:
The number 13 fits into 75 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 65 from 75 and we're left with 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 13

On to step 3:
When dividing 105 by 13, we get 8 with a remainder of 1.
The next digit of our result is 8. 
Result so far: 58.0
Deduct 104 from 105 and we're left with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 13

Advancing to step 4:
15 divided by 13 is 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 581.0
If we subtract 13 from 15, we get 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 13

On to step 5:
If we divide 29 by 13, we get 2 and a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 5812.0
If we subtract 26 from 29, we get 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 13

Let's proceed to step 6:
13 can be fit into 32 2 times, resulting in a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 58122.0
Deduct 26 from 32 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
13 can be fit into 60 4 times, resulting in a remainder of 8.
The next digit of our result is 4. 
Result so far: 58122.4
Subtracting 52 from 60 leaves us 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.

Step 8:
13 goes into 80 6 times with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 58122.46
Subtracting 78 from 80 leaves us with 2.
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 9:
13 can be fit into 20 1 times, resulting in a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 58122.461
Subtract 13 from 20 to 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.

Moving on to step 10:
13 can be fit into 70 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 58122.4615
Subtracting 65 from 70 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 11:
The number 13 fits into 50 3 times, leaving a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 58122.46153
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.

Step 12:
The number 13 fits into 110 8 times, leaving a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 58122.461538
Subtract 104 from 110 to 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.

On to step 13:
If we divide 60 by 13, we get 4 and a remainder of 8.
The next digit of our result is 4. 
Result so far: 58122.4615384
Deduct 52 from 60 and we're left 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.

Moving on to step 14:
The number 13 fits into 80 6 times, leaving a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 58122.46153846
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 quotient of the division is 58122.46153846, and the remainder is 2e-09.
