We divide 839506 by 13
The aim is to understand the frequency of 13 in 839506.

On to step 1:
13 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 13

Step 2:
When dividing 83 by 13, we get 6 with a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 78 from 83 to get 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 13

Step 3:
13 goes into 59 4 times with a remainder of 7.
The next digit of our result is 4. 
Result so far: 64.0
Deduct 52 from 59 and we're left with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 13

Moving on to step 4:
13 can be fit into 75 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 645.0
If we take 65 away from 75, we end up with 10.
Grab the next digit (0) from the dividend, add it to 10, then carry on: 100 / 13

On to step 5:
100 divided by 13 is 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 6457.0
Subtracting 91 from 100 leaves us with 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 13

Step 6:
When dividing 96 by 13, we get 7 with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 64577.0
If we take 91 away from 96, 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.

Advancing to step 7:
13 can be fit into 50 3 times, resulting in a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 64577.3
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.

Going ahead to step 8:
13 can be fit into 110 8 times, resulting in a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 64577.38
Deduct 104 from 110 and we're left 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.

Moving on to step 9:
13 goes into 60 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 64577.384
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 10:
80 divided by 13 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 64577.3846
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.

Moving on to step 11:
13 goes into 20 1 times with a remainder of 7.
The next digit of our result is 1. 
Result so far: 64577.38461
Deduct 13 from 20 and we're left 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.

Going ahead to step 12:
13 goes into 70 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 64577.384615
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.

Let's proceed to step 13:
The number 13 fits into 50 3 times, leaving a remainder of 11.
The next digit of our result is 3. 
Result so far: 64577.3846153
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:
If we divide 110 by 13, we get 8 and a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 64577.38461538
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.

The final result is 64577.38461538 with a remainder of 6e-09.
