We look at the division of 165935 by 49 
The aim is to understand the frequency of 49 in 165935.

Advancing to step 1:
49 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 49

Step 2:
If we divide 16 by 49, we get 0 and a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Take the next digit (5) from the dividend and append it to 16, then repeat: 165 / 49

On to step 3:
165 divided by 49 is 3 with a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 147 from 165, we get 18.
Append the next digit (9) from the dividend to 18 and continue with: 189 / 49

Moving on to step 4:
49 can be fit into 189 3 times, resulting in a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
The remainder is 42 after subtracting 147 from 189.
Bring next digit (3) of the dividend behind the 42 and repeat the process: 423 / 49

On to step 5:
The number 49 fits into 423 8 times, leaving a remainder of 31.
Record the quotient 8 as the next digit in the result. 
Result so far: 338.0
Subtracting 392 from 423 leaves us with 31.
Include the next digit (5) from the dividend after 31, then repeat: 315 / 49

On to step 6:
315 divided by 49 is 6 with a remainder of 21.
Write down 6 as next digit of the result. 
Result so far: 3386.0
Subtracting 294 from 315 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 7:
When dividing 210 by 49, we get 4 with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 3386.4
If we take 196 away from 210, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
49 can be fit into 140 2 times, resulting in a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 3386.42
The remainder is 42 after subtracting 98 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 9:
When dividing 420 by 49, we get 8 with a remainder of 28.
The next digit of our result is 8. 
Result so far: 3386.428
If we subtract 392 from 420, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 10:
49 goes into 280 5 times with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 3386.4285
The remainder is 35 after subtracting 245 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 11:
49 can be fit into 350 7 times, resulting in a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 3386.42857
If we subtract 343 from 350, we 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.

Advancing to step 12:
49 can be fit into 70 1 times, resulting in a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 3386.428571
If we subtract 49 from 70, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 13:
If we divide 210 by 49, we get 4 and a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 3386.4285714
If we take 196 away from 210, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 14:
If we divide 140 by 49, we get 2 and a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 3386.42857142
Deduct 98 from 140 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Our division results in 3386.42857142 with a remaining 4.2e-08.
