348622 divided by 13 
The aim is to understand the frequency of 13 in 348622.

On to step 1:
The number 13 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 13

Advancing to step 2:
If we divide 34 by 13, we get 2 and a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 26 from 34 leaves us with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 13

Advancing to step 3:
The number 13 fits into 88 6 times, leaving a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
If we take 78 away from 88, we end up with 10.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 13

Going ahead to step 4:
When dividing 106 by 13, we get 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 268.0
Subtract 104 from 106 to get 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 13

Step 5:
The number 13 fits into 22 1 times, leaving a remainder of 9.
The next digit of our result is 1. 
Result so far: 2681.0
Deduct 13 from 22 and we're left with 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 13

Moving on to step 6:
If we divide 92 by 13, we get 7 and a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 26817.0
Subtracting 91 from 92 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.

Step 7:
13 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 26817.0
Subtracting 0 from 10 leaves us 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.

Advancing to step 8:
13 goes into 100 7 times with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 26817.07
Subtract 91 from 100 to get 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 can be fit into 90 6 times, resulting in a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 26817.076
Subtracting 78 from 90 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 10:
The number 13 fits into 120 9 times, leaving a remainder of 3.
The next digit of our result is 9. 
Result so far: 26817.0769
If we subtract 117 from 120, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 11:
13 can be fit into 30 2 times, resulting in a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 26817.07692
The remainder is 4 after subtracting 26 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 12:
If we divide 40 by 13, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 26817.076923
Subtracting 39 from 40 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 13:
If we divide 10 by 13, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 26817.076923
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.

Advancing to step 14:
13 can be fit into 100 7 times, resulting in a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 26817.07692307
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.

The final result is 26817.07692307 with a remainder of 9e-09.
