968518 ÷ 13 
The aim is to understand the frequency of 13 in 968518.

Going ahead to step 1:
13 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 13

Going ahead to step 2:
96 divided by 13 is 7 with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 91 away from 96, we end up with 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 13

On to step 3:
13 goes into 58 4 times with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 74.0
Deduct 52 from 58 and we're left with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 13

On to step 4:
When dividing 65 by 13, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 745.0
If we subtract 65 from 65, we get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 13

Going ahead to step 5:
13 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 7450.0
If we subtract 0 from 1, we get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 13

Advancing to step 6:
18 divided by 13 is 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 74501.0
Subtracting 13 from 18 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.

Advancing to step 7:
The number 13 fits into 50 3 times, leaving a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 74501.3
Deduct 39 from 50 and we're left 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.

On to step 8:
13 goes into 110 8 times with a remainder of 6.
The next digit of our result is 8. 
Result so far: 74501.38
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.

Moving on to step 9:
13 goes into 60 4 times with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 74501.384
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.

Going ahead to step 10:
13 goes into 80 6 times with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 74501.3846
The remainder is 2 after subtracting 78 from 80.
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 11:
20 divided by 13 is 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 74501.38461
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 12:
The number 13 fits into 70 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 74501.384615
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.

Step 13:
13 can be fit into 50 3 times, resulting in a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 74501.3846153
If we subtract 39 from 50, we 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.

Moving on to step 14:
13 can be fit into 110 8 times, resulting in a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 74501.38461538
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.

Our division results in 74501.38461538 with a remaining 6e-09.
