Let's divide 100615 by 49
The aim is to understand the frequency of 49 in 100615.

Let's proceed to step 1:
If we divide 1 by 49, we get 0 and a remainder of 1.
The next digit of our result is 0. 
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

Moving on to step 2:
10 divided by 49 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Grab the next digit (0) from the dividend, add it to 10, then carry on: 100 / 49

Advancing to step 3:
100 divided by 49 is 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 2.0
If we take 98 away from 100, we end up with 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 49

Let's proceed to step 4:
The number 49 fits into 26 0 times, leaving a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Deduct 0 from 26 and we're left with 26.
Take the next digit (1) from the dividend and append it to 26, then repeat: 261 / 49

Step 5:
If we divide 261 by 49, we get 5 and a remainder of 16.
The number 5 becomes the next digit in our result. 
Result so far: 205.0
Subtracting 245 from 261 leaves us with 16.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 49

Step 6:
49 goes into 165 3 times with a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 2053.0
Subtracting 147 from 165 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 7:
If we divide 180 by 49, we get 3 and a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 2053.3
The remainder is 33 after subtracting 147 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 8:
49 goes into 330 6 times with a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 2053.36
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.

Moving on to step 9:
When dividing 360 by 49, we get 7 with a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 2053.367
Subtract 343 from 360 to 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.

Let's proceed to step 10:
When dividing 170 by 49, we get 3 with a remainder of 23.
The next digit of our result is 3. 
Result so far: 2053.3673
The remainder is 23 after subtracting 147 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 11:
The number 49 fits into 230 4 times, leaving a remainder of 34.
The next digit of our result is 4. 
Result so far: 2053.36734
Deduct 196 from 230 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 12:
When dividing 340 by 49, we get 6 with a remainder of 46.
Write down 6 as next digit of the result. 
Result so far: 2053.367346
The remainder is 46 after subtracting 294 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 13:
When dividing 460 by 49, we get 9 with a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 2053.3673469
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.

Moving on to step 14:
49 can be fit into 190 3 times, resulting in a remainder of 43.
The number 3 becomes the next digit in our result. 
Result so far: 2053.36734693
If we subtract 147 from 190, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

The final outcome is 2053.36734693, with a leftover of 4.3e-08.
