We're dividing 407015 by 49 
The aim is to understand the frequency of 49 in 407015.

Going ahead to step 1:
When dividing 4 by 49, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 49

Step 2:
40 divided by 49 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Bring next digit (7) of the dividend behind the 40 and repeat the process: 407 / 49

On to step 3:
49 goes into 407 8 times with a remainder of 15.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 392 from 407, we get 15.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 49

Moving on to step 4:
49 can be fit into 150 3 times, resulting in a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 83.0
If we take 147 away from 150, we end up with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 49

Let's proceed to step 5:
The number 49 fits into 31 0 times, leaving a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 830.0
The remainder is 31 after subtracting 0 from 31.
Fetch the next digit (5) from the dividend, attach it to 31 and continue: 315 / 49

Step 6:
315 divided by 49 is 6 with a remainder of 21.
Use 6 as the next digit of our solution. 
Result so far: 8306.0
If we take 294 away from 315, we end up 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.

Going ahead to step 7:
49 can be fit into 210 4 times, resulting in a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 8306.4
Subtract 196 from 210 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
The number 49 fits into 140 2 times, leaving a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 8306.42
If we subtract 98 from 140, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 9:
49 goes into 420 8 times with a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 8306.428
The remainder is 28 after subtracting 392 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 10:
280 divided by 49 is 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 8306.4285
Subtracting 245 from 280 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 11:
The number 49 fits into 350 7 times, leaving a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 8306.42857
Subtracting 343 from 350 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 12:
70 divided by 49 is 1 with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 8306.428571
Subtracting 49 from 70 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.

Advancing to step 13:
49 can be fit into 210 4 times, resulting in a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 8306.4285714
If we subtract 196 from 210, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 14:
49 can be fit into 140 2 times, resulting in a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 8306.42857142
Subtracting 98 from 140 leaves us 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.

The final result is 8306.42857142 with a remainder of 4.2e-08.
