We divide 709971 by 13
The aim is to understand the frequency of 13 in 709971.

Let's proceed to step 1:
13 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 13

Let's proceed to step 2:
When dividing 70 by 13, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 65 away from 70, we end up with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 13

Let's proceed to step 3:
The number 13 fits into 59 4 times, leaving a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 54.0
If we subtract 52 from 59, we get 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 13

On to step 4:
If we divide 79 by 13, we get 6 and a remainder of 1.
The next digit of our result is 6. 
Result so far: 546.0
The remainder is 1 after subtracting 78 from 79.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 13

On to step 5:
13 goes into 17 1 times with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 5461.0
If we take 13 away from 17, we end up with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 13

Let's proceed to step 6:
41 divided by 13 is 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 54613.0
If we take 39 away from 41, 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 7:
20 divided by 13 is 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 54613.1
If we take 13 away from 20, we end up 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:
When dividing 70 by 13, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 54613.15
If we subtract 65 from 70, we get 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 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: 54613.153
If we take 39 away from 50, we end up 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 10:
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: 54613.1538
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.

Let's proceed to step 11:
When dividing 60 by 13, we get 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 54613.15384
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 12:
If we divide 80 by 13, we get 6 and a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 54613.153846
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 13:
The number 13 fits into 20 1 times, leaving a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 54613.1538461
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.

Let's proceed to step 14:
If we divide 70 by 13, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 54613.15384615
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 final outcome is 54613.15384615, with a leftover of 5e-09.
