We look at the division of 801255 by 49 
The aim is to understand the frequency of 49 in 801255.

Moving on to step 1:
The number 49 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 49

On to step 2:
49 goes into 80 1 times with a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 49 from 80 leaves us with 31.
Bring next digit (1) of the dividend behind the 31 and repeat the process: 311 / 49

Moving on to step 3:
The number 49 fits into 311 6 times, leaving a remainder of 17.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we subtract 294 from 311, we get 17.
Append the next digit (2) from the dividend to 17 and continue with: 172 / 49

On to step 4:
If we divide 172 by 49, we get 3 and a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 163.0
Subtracting 147 from 172 leaves us with 25.
Include the next digit (5) from the dividend after 25, then repeat: 255 / 49

Let's proceed to step 5:
255 divided by 49 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 1635.0
The remainder is 10 after subtracting 245 from 255.
Grab the next digit (5) from the dividend, add it to 10, then carry on: 105 / 49

On to step 6:
When dividing 105 by 49, we get 2 with a remainder of 7.
The next digit of our result is 2. 
Result so far: 16352.0
Subtract 98 from 105 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
49 goes into 70 1 times with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 16352.1
The remainder is 21 after subtracting 49 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 8:
49 goes into 210 4 times with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 16352.14
If we take 196 away from 210, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
49 goes into 140 2 times with a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 16352.142
Subtract 98 from 140 to 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.

Advancing to step 10:
49 can be fit into 420 8 times, resulting in a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 16352.1428
If we take 392 away from 420, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 11:
49 can be fit into 280 5 times, resulting in a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 16352.14285
Subtract 245 from 280 to get 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 12:
49 can be fit into 350 7 times, resulting in a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 16352.142857
If we take 343 away from 350, we end up 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.

Going ahead to step 13:
49 can be fit into 70 1 times, resulting in a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 16352.1428571
If we take 49 away from 70, 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.

On to step 14:
49 can be fit into 210 4 times, resulting in a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 16352.14285714
Deduct 196 from 210 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 16352.14285714 with a remaining 1.4e-08.
