Let's divide 501525 by 49
The aim is to understand the frequency of 49 in 501525.

Advancing to step 1:
49 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 49

On to step 2:
The number 49 fits into 50 1 times, leaving a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 1 after subtracting 49 from 50.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 49

Moving on to step 3:
When dividing 11 by 49, we get 0 with a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 11, we get 11.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 49

Step 4:
49 can be fit into 115 2 times, resulting in a remainder of 17.
The next digit of our result is 2. 
Result so far: 102.0
If we subtract 98 from 115, we get 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 49

Going ahead to step 5:
If we divide 172 by 49, we get 3 and a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 1023.0
If we subtract 147 from 172, we get 25.
Append the next digit (5) from the dividend to 25 and continue with: 255 / 49

Advancing to step 6:
255 divided by 49 is 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 10235.0
Subtract 245 from 255 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 7:
If we divide 100 by 49, we get 2 and a remainder of 2.
The next digit of our result is 2. 
Result so far: 10235.2
The remainder is 2 after subtracting 98 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
The number 49 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 10235.2
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
200 divided by 49 is 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 10235.204
If we subtract 196 from 200, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
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: 10235.204
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
49 can be fit into 400 8 times, resulting in a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 10235.20408
If we subtract 392 from 400, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
The number 49 fits into 80 1 times, leaving a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 10235.204081
If we take 49 away from 80, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 13:
If we divide 310 by 49, we get 6 and a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 10235.2040816
If we subtract 294 from 310, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 14:
When dividing 160 by 49, we get 3 with a remainder of 13.
The next digit of our result is 3. 
Result so far: 10235.20408163
Subtract 147 from 160 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Our division results in 10235.20408163 with a remaining 1.3e-08.
