We look at the division of 109807 by 49 
The aim is to understand the frequency of 49 in 109807.

On to step 1:
1 divided by 49 is 0 with 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.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 49

Going ahead to step 2:
If we divide 10 by 49, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 49

Advancing to step 3:
49 goes into 109 2 times with a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 98 from 109 and we're left with 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 49

Let's proceed to step 4:
The number 49 fits into 118 2 times, leaving a remainder of 20.
The next digit of our result is 2. 
Result so far: 22.0
If we subtract 98 from 118, we get 20.
Grab the next digit (0) from the dividend, add it to 20, then carry on: 200 / 49

Advancing to step 5:
49 can be fit into 200 4 times, resulting in a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 224.0
The remainder is 4 after subtracting 196 from 200.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 49

Step 6:
The number 49 fits into 47 0 times, leaving a remainder of 47.
The number 0 becomes the next digit in our result. 
Result so far: 2240.0
Subtracting 0 from 47 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 7:
49 goes into 470 9 times with a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 2240.9
If we take 441 away from 470, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 8:
If we divide 290 by 49, we get 5 and a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 2240.95
If we take 245 away from 290, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 9:
450 divided by 49 is 9 with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 2240.959
Subtracting 441 from 450 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.

Step 10:
The number 49 fits into 90 1 times, leaving a remainder of 41.
The next digit of our result is 1. 
Result so far: 2240.9591
If we subtract 49 from 90, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 11:
49 can be fit into 410 8 times, resulting in a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 2240.95918
Subtract 392 from 410 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 12:
49 goes into 180 3 times with a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 2240.959183
If we take 147 away from 180, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 13:
If we divide 330 by 49, we get 6 and a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 2240.9591836
If we take 294 away from 330, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 14:
49 goes into 360 7 times with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 2240.95918367
If we subtract 343 from 360, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Our division results in 2240.95918367 with a remaining 1.7e-08.
