We divide 436291 by 13
The aim is to understand the frequency of 13 in 436291.

Let's proceed to step 1:
If we divide 4 by 13, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 13

Going ahead to step 2:
If we divide 43 by 13, we get 3 and a remainder of 4.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 4 after subtracting 39 from 43.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 13

Advancing to step 3:
The number 13 fits into 46 3 times, leaving a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 33.0
The remainder is 7 after subtracting 39 from 46.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 13

Advancing to step 4:
13 can be fit into 72 5 times, resulting in a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 335.0
If we take 65 away from 72, we end up with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 13

Advancing to step 5:
13 goes into 79 6 times with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 3356.0
If we take 78 away from 79, we end up with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 13

Going ahead to step 6:
11 divided by 13 is 0 with a remainder of 11.
The next digit of our result is 0. 
Result so far: 33560.0
If we subtract 0 from 11, 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.

Let's proceed to step 7:
13 goes into 110 8 times with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 33560.8
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 8:
13 goes into 60 4 times with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 33560.84
If we subtract 52 from 60, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
When dividing 80 by 13, we get 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 33560.846
Deduct 78 from 80 and we're left 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.

Moving on to step 10:
When dividing 20 by 13, we get 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 33560.8461
If we subtract 13 from 20, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 11:
70 divided by 13 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 33560.84615
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.

Step 12:
13 can be fit into 50 3 times, resulting in a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 33560.846153
Subtracting 39 from 50 leaves us 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.

Moving on to step 13:
If we divide 110 by 13, we get 8 and a remainder of 6.
The next digit of our result is 8. 
Result so far: 33560.8461538
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.

Advancing to step 14:
13 can be fit into 60 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 33560.84615384
If we take 52 away from 60, we end up 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.

The final outcome is 33560.84615384, with a leftover of 8e-09.
