We look at the division of 941994 by 13 
The aim is to understand the frequency of 13 in 941994.

Moving on to step 1:
9 divided by 13 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 13

Step 2:
13 goes into 94 7 times with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 91 from 94 and we're left with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 13

Moving on to step 3:
The number 13 fits into 31 2 times, leaving a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 72.0
Deduct 26 from 31 and we're left with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 13

Let's proceed to step 4:
The number 13 fits into 59 4 times, leaving a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 724.0
Subtract 52 from 59 to get 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 13

Let's proceed to step 5:
The number 13 fits into 79 6 times, leaving a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 7246.0
The remainder is 1 after subtracting 78 from 79.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 13

Advancing to step 6:
The number 13 fits into 14 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 72461.0
Subtracting 13 from 14 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.

Let's proceed to step 7:
13 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 72461.0
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.

On to step 8:
The number 13 fits into 100 7 times, leaving a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 72461.07
Deduct 91 from 100 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.

On to step 9:
13 goes into 90 6 times with a remainder of 12.
The next digit of our result is 6. 
Result so far: 72461.076
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.

Step 10:
13 can be fit into 120 9 times, resulting in a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 72461.0769
Deduct 117 from 120 and we're left 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.

Let's proceed to step 11:
The number 13 fits into 30 2 times, leaving a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 72461.07692
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.

Advancing to step 12:
13 can be fit into 40 3 times, resulting in a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 72461.076923
If we subtract 39 from 40, we 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.

Let's proceed to step 13:
If we divide 10 by 13, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 72461.076923
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.

On to step 14:
If we divide 100 by 13, we get 7 and a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 72461.07692307
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.

In conclusion, the division gives 72461.07692307 with a balance of 9e-09.
