We divide 98368046 by 13
The aim is to understand the frequency of 13 in 98368046.

On to step 1:
When dividing 9 by 13, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 13

Going ahead to step 2:
98 divided by 13 is 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 91 from 98, we get 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 13

Let's proceed to step 3:
When dividing 73 by 13, we get 5 with a remainder of 8.
The next digit of our result is 5. 
Result so far: 75.0
Deduct 65 from 73 and we're left with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 13

Going ahead to step 4:
When dividing 86 by 13, we get 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 756.0
The remainder is 8 after subtracting 78 from 86.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 13

Moving on to step 5:
When dividing 88 by 13, we get 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 7566.0
Subtract 78 from 88 to get 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 13

Moving on to step 6:
The number 13 fits into 100 7 times, leaving a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 75667.0
Deduct 91 from 100 and we're left with 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 13

Going ahead to step 7:
If we divide 94 by 13, we get 7 and a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 756677.0
If we subtract 91 from 94, we get 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 13

On to step 8:
When dividing 36 by 13, we get 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 7566772.0
Subtracting 26 from 36 leaves us 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.

Moving on to step 9:
When dividing 100 by 13, we get 7 with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 7566772.7
Subtracting 91 from 100 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to 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: 7566772.76
Subtracting 78 from 90 leaves us 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.

Going ahead to step 11:
120 divided by 13 is 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 7566772.769
If we take 117 away from 120, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 12:
13 can be fit into 30 2 times, resulting in a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 7566772.7692
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.

Advancing to step 13:
13 can be fit into 40 3 times, resulting in a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 7566772.76923
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.
Put 0 as the next digit of the answer. 
Result so far: 7566772.76923
Subtracting 0 from 10 leaves us 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.

On to step 15:
13 can be fit into 100 7 times, resulting in a remainder of 9.
The next digit of our result is 7. 
Result so far: 7566772.7692307
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.

Let's proceed to step 16:
90 divided by 13 is 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 7566772.76923076
If we subtract 78 from 90, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 7566772.76923076 with a remaining 1.2e-08.
