We divide 764389 by 13
The aim is to understand the frequency of 13 in 764389.

Advancing to step 1:
If we divide 7 by 13, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 13

Going ahead to step 2:
13 goes into 76 5 times with a remainder of 11.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 65 from 76, we get 11.
Grab the next digit (4) from the dividend, add it to 11, then carry on: 114 / 13

Step 3:
114 divided by 13 is 8 with a remainder of 10.
The next digit of our result is 8. 
Result so far: 58.0
If we subtract 104 from 114, we get 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 13

On to step 4:
If we divide 103 by 13, we get 7 and a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 587.0
Subtracting 91 from 103 leaves us with 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 13

Let's proceed to step 5:
13 goes into 128 9 times with a remainder of 11.
The next digit of our result is 9. 
Result so far: 5879.0
If we subtract 117 from 128, we get 11.
Include the next digit (9) from the dividend after 11, then repeat: 119 / 13

Moving on to step 6:
13 can be fit into 119 9 times, resulting in a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 58799.0
Subtracting 117 from 119 leaves us 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.

On to step 7:
If we divide 20 by 13, we get 1 and a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 58799.1
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.

Moving on to step 8:
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: 58799.15
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 9:
If we divide 50 by 13, we get 3 and a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 58799.153
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 10:
13 goes into 110 8 times with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 58799.1538
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 11:
13 goes into 60 4 times with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 58799.15384
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.

Let's proceed to step 12:
When dividing 80 by 13, we get 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 58799.153846
If we take 78 away from 80, we end up 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.

Going ahead to step 13:
20 divided by 13 is 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 58799.1538461
Subtract 13 from 20 to 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 14:
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: 58799.15384615
Subtracting 65 from 70 leaves us 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.

The quotient of the division is 58799.15384615, and the remainder is 5e-09.
