84913626 ÷ 13 
The aim is to understand the frequency of 13 in 84913626.

Advancing to step 1:
When dividing 8 by 13, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 13

On to step 2:
84 divided by 13 is 6 with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 78 from 84 and we're left with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 13

Moving on to step 3:
69 divided by 13 is 5 with a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 65.0
Subtract 65 from 69 to get 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 13

Step 4:
13 goes into 41 3 times with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 653.0
If we take 39 away from 41, we end up with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 13

Let's proceed to step 5:
13 goes into 23 1 times with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 6531.0
The remainder is 10 after subtracting 13 from 23.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 13

Let's proceed to step 6:
The number 13 fits into 106 8 times, leaving a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 65318.0
Subtracting 104 from 106 leaves us with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 13

Moving on to step 7:
13 can be fit into 22 1 times, resulting in a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 653181.0
The remainder is 9 after subtracting 13 from 22.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 13

Going ahead to step 8:
13 goes into 96 7 times with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 6531817.0
If we subtract 91 from 96, 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.

Going ahead to step 9:
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: 6531817.3
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.

On to step 10:
110 divided by 13 is 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 6531817.38
Subtract 104 from 110 to 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.

On to step 11:
60 divided by 13 is 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 6531817.384
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.

Moving on to step 12:
The number 13 fits into 80 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 6531817.3846
Subtracting 78 from 80 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 13:
The number 13 fits into 20 1 times, leaving a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 6531817.38461
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 14:
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: 6531817.384615
Deduct 65 from 70 and we're left 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.

Going ahead to step 15:
If we divide 50 by 13, we get 3 and a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 6531817.3846153
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.

Step 16:
13 goes into 110 8 times with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 6531817.38461538
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.

The final outcome is 6531817.38461538, with a leftover of 6e-09.
