We divide 981413 by 13
The aim is to understand the frequency of 13 in 981413.

Moving on to step 1:
9 divided by 13 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 13

Moving on to step 2:
13 goes into 98 7 times with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 91 from 98 leaves us with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 13

On to step 3:
When dividing 71 by 13, we get 5 with a remainder of 6.
The next digit of our result is 5. 
Result so far: 75.0
If we take 65 away from 71, we end up with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 13

Moving on to step 4:
13 goes into 64 4 times with a remainder of 12.
The next digit of our result is 4. 
Result so far: 754.0
Subtracting 52 from 64 leaves us with 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 13

Step 5:
If we divide 121 by 13, we get 9 and a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 7549.0
Subtracting 117 from 121 leaves us with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 13

Let's proceed to step 6:
13 can be fit into 43 3 times, resulting in a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 75493.0
The remainder is 4 after subtracting 39 from 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
The number 13 fits into 40 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 75493.3
Subtracting 39 from 40 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 8:
The number 13 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 75493.3
If we take 0 away from 10, we end up 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.

Step 9:
13 goes into 100 7 times with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 75493.307
The remainder is 9 after subtracting 91 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 10:
If we divide 90 by 13, we get 6 and a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 75493.3076
If we take 78 away from 90, we end up 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.

On to step 11:
13 can be fit into 120 9 times, resulting in a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 75493.30769
If we subtract 117 from 120, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 12:
13 goes into 30 2 times with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 75493.307692
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.

Step 13:
The number 13 fits into 40 3 times, leaving a remainder of 1.
The next digit of our result is 3. 
Result so far: 75493.3076923
If we take 39 away from 40, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 14:
If we divide 10 by 13, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 75493.3076923
The remainder is 10 after subtracting 0 from 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 75493.3076923 and a remainder of 1e-08.
