Let's divide 653790 by 13
The aim is to understand the frequency of 13 in 653790.

Moving on to step 1:
When dividing 6 by 13, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 13

Advancing to step 2:
When dividing 65 by 13, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 0 after subtracting 65 from 65.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 13

Moving on to step 3:
If we divide 3 by 13, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 50.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 13

Moving on to step 4:
13 can be fit into 37 2 times, resulting in a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 502.0
Subtracting 26 from 37 leaves us with 11.
Grab the next digit (9) from the dividend, add it to 11, then carry on: 119 / 13

Going ahead to step 5:
119 divided by 13 is 9 with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 5029.0
Subtracting 117 from 119 leaves us with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 13

On to step 6:
If we divide 20 by 13, we get 1 and a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 50291.0
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.

Moving on to step 7:
If we divide 70 by 13, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 50291.5
If we take 65 away from 70, we end up 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.

Moving on to step 8:
The number 13 fits into 50 3 times, leaving a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 50291.53
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 9:
If we divide 110 by 13, we get 8 and a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 50291.538
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.

On to step 10:
The number 13 fits into 60 4 times, leaving a remainder of 8.
The next digit of our result is 4. 
Result so far: 50291.5384
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.

Going ahead to step 11:
80 divided by 13 is 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 50291.53846
If we subtract 78 from 80, we 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.

On to step 12:
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: 50291.538461
Subtracting 13 from 20 leaves us 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.

Moving on to step 13:
13 goes into 70 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 50291.5384615
The remainder is 5 after subtracting 65 from 70.
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 14:
13 goes into 50 3 times with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 50291.53846153
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.

The final result is 50291.53846153 with a remainder of 1.1e-08.
