We look at the division of 808995 by 49 
The aim is to understand the frequency of 49 in 808995.

Going ahead to step 1:
The number 49 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 49

Advancing to step 2:
80 divided by 49 is 1 with a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 49 from 80, we get 31.
Grab the next digit (8) from the dividend, add it to 31, then carry on: 318 / 49

Step 3:
The number 49 fits into 318 6 times, leaving a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtract 294 from 318 to get 24.
Include the next digit (9) from the dividend after 24, then repeat: 249 / 49

Going ahead to step 4:
If we divide 249 by 49, we get 5 and a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 165.0
Subtract 245 from 249 to get 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 49

Going ahead to step 5:
The number 49 fits into 49 1 times, leaving a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1651.0
Subtracting 49 from 49 leaves us with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 49

Going ahead to step 6:
49 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 16510.0
Subtracting 0 from 5 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.

Going ahead to step 7:
49 can be fit into 50 1 times, resulting in a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 16510.1
Subtracting 49 from 50 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.

Step 8:
10 divided by 49 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 16510.1
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
49 goes into 100 2 times with a remainder of 2.
The next digit of our result is 2. 
Result so far: 16510.102
If we subtract 98 from 100, we 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.

Going ahead to step 10:
49 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 16510.102
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
When dividing 200 by 49, we get 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 16510.10204
The remainder is 4 after subtracting 196 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 12:
If we divide 40 by 49, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 16510.10204
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 13:
When dividing 400 by 49, we get 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 16510.1020408
Deduct 392 from 400 and we're left 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.

Advancing to step 14:
When dividing 80 by 49, we get 1 with a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 16510.10204081
Subtract 49 from 80 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The final outcome is 16510.10204081, with a leftover of 3.1e-08.
