We're dividing 933185 by 13 
The aim is to understand the frequency of 13 in 933185.

Advancing to step 1:
9 divided by 13 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 13

On to step 2:
The number 13 fits into 93 7 times, leaving a remainder of 2.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 91 from 93 and we're left with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 13

Moving on to step 3:
23 divided by 13 is 1 with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 71.0
Subtract 13 from 23 to get 10.
Grab the next digit (1) from the dividend, add it to 10, then carry on: 101 / 13

Advancing to step 4:
101 divided by 13 is 7 with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 717.0
If we subtract 91 from 101, we get 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 13

Advancing to step 5:
When dividing 108 by 13, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 7178.0
The remainder is 4 after subtracting 104 from 108.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 13

Moving on to step 6:
The number 13 fits into 45 3 times, leaving a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 71783.0
Subtracting 39 from 45 leaves us 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.

Step 7:
When dividing 60 by 13, we get 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 71783.4
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.
Put 6 as the next digit of the answer. 
Result so far: 71783.46
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.

Step 9:
20 divided by 13 is 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 71783.461
The remainder is 7 after subtracting 13 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 10:
13 can be fit into 70 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 71783.4615
Subtract 65 from 70 to get 5.
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 11:
If we divide 50 by 13, we get 3 and a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 71783.46153
The remainder is 11 after subtracting 39 from 50.
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:
13 goes into 110 8 times with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 71783.461538
Subtracting 104 from 110 leaves us 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.

Advancing to step 13:
The number 13 fits into 60 4 times, leaving a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 71783.4615384
If we subtract 52 from 60, we get 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 14:
13 can be fit into 80 6 times, resulting in a remainder of 2.
The next digit of our result is 6. 
Result so far: 71783.46153846
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.

The final outcome is 71783.46153846, with a leftover of 2e-09.
