We divide 623317 by 49
The aim is to understand the frequency of 49 in 623317.

On to step 1:
49 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 49

Step 2:
49 can be fit into 62 1 times, resulting in a remainder of 13.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 49 from 62 and we're left with 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 49

Moving on to step 3:
133 divided by 49 is 2 with a remainder of 35.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 98 from 133 leaves us with 35.
Include the next digit (3) from the dividend after 35, then repeat: 353 / 49

Step 4:
49 can be fit into 353 7 times, resulting in a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 127.0
If we subtract 343 from 353, we get 10.
Grab the next digit (1) from the dividend, add it to 10, then carry on: 101 / 49

Let's proceed to step 5:
The number 49 fits into 101 2 times, leaving a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 1272.0
Subtracting 98 from 101 leaves us with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 49

Moving on to step 6:
49 goes into 37 0 times with a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 12720.0
The remainder is 37 after subtracting 0 from 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 7:
The number 49 fits into 370 7 times, leaving a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 12720.7
If we subtract 343 from 370, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 8:
49 goes into 270 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 12720.75
Subtract 245 from 270 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 9:
If we divide 250 by 49, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 12720.755
Deduct 245 from 250 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 12720.755 with a remainder of 0.0005.
