We look at the division of 100680 by 49 
The aim is to understand the frequency of 49 in 100680.

Let's proceed to step 1:
The number 49 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 49

On to step 2:
The number 49 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 49

On to step 3:
If we divide 100 by 49, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 98 from 100 leaves us with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 49

Step 4:
If we divide 26 by 49, we get 0 and a remainder of 26.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Deduct 0 from 26 and we're left with 26.
Take the next digit (8) from the dividend and append it to 26, then repeat: 268 / 49

Advancing to step 5:
49 goes into 268 5 times with a remainder of 23.
The number 5 becomes the next digit in our result. 
Result so far: 205.0
Subtracting 245 from 268 leaves us with 23.
Take the next digit (0) from the dividend and append it to 23, then repeat: 230 / 49

On to step 6:
The number 49 fits into 230 4 times, leaving a remainder of 34.
The next digit of our result is 4. 
Result so far: 2054.0
If we subtract 196 from 230, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 7:
If we divide 340 by 49, we get 6 and a remainder of 46.
Use 6 as the next digit of our solution. 
Result so far: 2054.6
Subtracting 294 from 340 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 8:
When dividing 460 by 49, we get 9 with a remainder of 19.
The next digit of our result is 9. 
Result so far: 2054.69
If we take 441 away from 460, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 9:
The number 49 fits into 190 3 times, leaving a remainder of 43.
The number 3 becomes the next digit in our result. 
Result so far: 2054.693
If we take 147 away from 190, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 10:
49 can be fit into 430 8 times, resulting in a remainder of 38.
The next digit of our result is 8. 
Result so far: 2054.6938
The remainder is 38 after subtracting 392 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 11:
When dividing 380 by 49, we get 7 with a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 2054.69387
If we subtract 343 from 380, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 12:
The number 49 fits into 370 7 times, leaving a remainder of 27.
The next digit of our result is 7. 
Result so far: 2054.693877
Deduct 343 from 370 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Our division results in 2054.693877 with a remaining 2.7e-06.
