We divide 98191606 by 13
The aim is to understand the frequency of 13 in 98191606.

Going ahead to step 1:
When dividing 9 by 13, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 13

Step 2:
13 goes into 98 7 times with a remainder of 7.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 91 from 98, we get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 13

Let's proceed to step 3:
When dividing 71 by 13, we get 5 with a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 75.0
The remainder is 6 after subtracting 65 from 71.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 13

Advancing to step 4:
69 divided by 13 is 5 with a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 755.0
Subtract 65 from 69 to get 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 13

Step 5:
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: 7553.0
If we take 39 away from 41, we end up with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 13

Going ahead to step 6:
When dividing 26 by 13, we get 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 75532.0
Subtract 26 from 26 to get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 13

On to step 7:
0 divided by 13 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 755320.0
Deduct 0 from 0 and we're left with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 13

Advancing to step 8:
13 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 7553200.0
Subtracting 0 from 6 leaves us 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.

Going ahead to step 9:
The number 13 fits into 60 4 times, leaving a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 7553200.4
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.

Step 10:
If we divide 80 by 13, we get 6 and a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 7553200.46
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.

On to step 11:
20 divided by 13 is 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 7553200.461
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 12:
If we divide 70 by 13, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 7553200.4615
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.

Step 13:
50 divided by 13 is 3 with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 7553200.46153
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.

Going ahead to step 14:
110 divided by 13 is 8 with a remainder of 6.
The next digit of our result is 8. 
Result so far: 7553200.461538
Subtracting 104 from 110 leaves us 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.

Going ahead to step 15:
If we divide 60 by 13, we get 4 and a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 7553200.4615384
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.

Moving on to step 16:
The number 13 fits into 80 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 7553200.46153846
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 7553200.46153846, and the remainder is 2e-09.
