Let's divide 949938 by 13
The aim is to understand the frequency of 13 in 949938.

On to step 1:
If we divide 9 by 13, we get 0 and 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.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 13

Going ahead to step 2:
94 divided by 13 is 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 91 from 94 to get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 13

Let's proceed to step 3:
The number 13 fits into 39 3 times, leaving a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 73.0
Subtracting 39 from 39 leaves us with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 13

Step 4:
13 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 730.0
If we subtract 0 from 9, we get 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 13

Going ahead to step 5:
13 goes into 93 7 times with a remainder of 2.
The next digit of our result is 7. 
Result so far: 7307.0
Deduct 91 from 93 and we're left with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 13

Going ahead to step 6:
The number 13 fits into 28 2 times, leaving a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 73072.0
Subtracting 26 from 28 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.

Advancing to step 7:
20 divided by 13 is 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 73072.1
If we take 13 away from 20, we end up with 7.
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 8:
If we divide 70 by 13, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 73072.15
If we subtract 65 from 70, we 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 9:
13 goes into 50 3 times with a remainder of 11.
The next digit of our result is 3. 
Result so far: 73072.153
Subtract 39 from 50 to get 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 10:
110 divided by 13 is 8 with a remainder of 6.
The next digit of our result is 8. 
Result so far: 73072.1538
If we take 104 away from 110, we end up 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 11:
If we divide 60 by 13, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 73072.15384
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.

On to step 12:
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: 73072.153846
If we take 78 away from 80, we end up 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 13:
20 divided by 13 is 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 73072.1538461
Subtracting 13 from 20 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 14:
The number 13 fits into 70 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 73072.15384615
The remainder is 5 after subtracting 65 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 73072.15384615, and the remainder is 5e-09.
