793836 ÷ 13 
The aim is to understand the frequency of 13 in 793836.

Step 1:
13 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 13

Advancing to step 2:
13 can be fit into 79 6 times, resulting in a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 78 from 79, we get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 13

On to step 3:
13 divided by 13 is 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 61.0
Subtract 13 from 13 to get 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 13

Advancing to step 4:
13 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 610.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 13

Moving on to step 5:
13 can be fit into 83 6 times, resulting in a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 6106.0
Deduct 78 from 83 and we're left with 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 13

On to step 6:
When dividing 56 by 13, we get 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 61064.0
If we subtract 52 from 56, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
When dividing 40 by 13, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 61064.3
Subtract 39 from 40 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 8:
If we divide 10 by 13, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 61064.3
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.

On to step 9:
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: 61064.307
If we subtract 91 from 100, we 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.

Advancing to step 10:
13 can be fit into 90 6 times, resulting in a remainder of 12.
The next digit of our result is 6. 
Result so far: 61064.3076
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 11:
When dividing 120 by 13, we get 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 61064.30769
Deduct 117 from 120 and we're left with 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 12:
13 can be fit into 30 2 times, resulting in a remainder of 4.
The next digit of our result is 2. 
Result so far: 61064.307692
Subtract 26 from 30 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 13:
When dividing 40 by 13, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 61064.3076923
If we subtract 39 from 40, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 14:
13 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 61064.3076923
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 61064.3076923 and a remainder of 1e-08.
