We divide 686626 by 13
The aim is to understand the frequency of 13 in 686626.

Let's proceed to step 1:
13 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 13

Advancing to step 2:
When dividing 68 by 13, we get 5 with a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 65 from 68 to get 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 13

Step 3:
13 goes into 36 2 times with a remainder of 10.
The next digit of our result is 2. 
Result so far: 52.0
Deduct 26 from 36 and we're left with 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 13

Advancing to step 4:
When dividing 106 by 13, we get 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 528.0
Deduct 104 from 106 and we're left with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 13

Advancing to step 5:
If we divide 22 by 13, we get 1 and a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 5281.0
If we subtract 13 from 22, we get 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 13

Let's proceed to step 6:
If we divide 96 by 13, we get 7 and a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 52817.0
Subtract 91 from 96 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.

Advancing to step 7:
The number 13 fits into 50 3 times, leaving a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 52817.3
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.

Step 8:
If we divide 110 by 13, we get 8 and a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 52817.38
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.

Going ahead to step 9:
13 goes into 60 4 times with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 52817.384
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:
80 divided by 13 is 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 52817.3846
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.

Going ahead 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: 52817.38461
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.

Let's proceed to step 12:
13 goes into 70 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 52817.384615
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.

On to step 13:
50 divided by 13 is 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 52817.3846153
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.

Let's proceed to step 14:
110 divided by 13 is 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 52817.38461538
If we subtract 104 from 110, we 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.

The quotient of the division is 52817.38461538, and the remainder is 6e-09.
