786336 ÷ 13 
The aim is to understand the frequency of 13 in 786336.

Moving on to step 1:
13 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 13

On to step 2:
When dividing 78 by 13, we get 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 78 from 78 leaves us with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 13

Going ahead to step 3:
If we divide 6 by 13, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 60.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 13

Step 4:
13 can be fit into 63 4 times, resulting in a remainder of 11.
The next digit of our result is 4. 
Result so far: 604.0
Subtracting 52 from 63 leaves us with 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 13

Let's proceed to step 5:
13 goes into 113 8 times with a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 6048.0
Subtracting 104 from 113 leaves us with 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 13

On to step 6:
If we divide 96 by 13, we get 7 and a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 60487.0
Deduct 91 from 96 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.

Let's proceed to step 7:
13 can be fit into 50 3 times, resulting in a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 60487.3
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.

Advancing to step 8:
13 can be fit into 110 8 times, resulting in a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 60487.38
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.

Step 9:
When dividing 60 by 13, we get 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 60487.384
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:
If we divide 80 by 13, we get 6 and a remainder of 2.
The next digit of our result is 6. 
Result so far: 60487.3846
Subtract 78 from 80 to 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.

Moving on to step 11:
If we divide 20 by 13, we get 1 and a remainder of 7.
The next digit of our result is 1. 
Result so far: 60487.38461
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.

Advancing to step 12:
70 divided by 13 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 60487.384615
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 13:
If we divide 50 by 13, we get 3 and a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 60487.3846153
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 14:
The number 13 fits into 110 8 times, leaving a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 60487.38461538
The remainder is 6 after subtracting 104 from 110.
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 60487.38461538, with a leftover of 6e-09.
