We're dividing 810855 by 49 
The aim is to understand the frequency of 49 in 810855.

Going ahead to step 1:
8 divided by 49 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 49

Let's proceed to step 2:
81 divided by 49 is 1 with a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 32 after subtracting 49 from 81.
Fetch the next digit (0) from the dividend, attach it to 32 and continue: 320 / 49

Let's proceed to step 3:
49 goes into 320 6 times with a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtract 294 from 320 to get 26.
Grab the next digit (8) from the dividend, add it to 26, then carry on: 268 / 49

Advancing to step 4:
49 goes into 268 5 times with a remainder of 23.
The number 5 becomes the next digit in our result. 
Result so far: 165.0
If we subtract 245 from 268, we get 23.
Include the next digit (5) from the dividend after 23, then repeat: 235 / 49

Step 5:
When dividing 235 by 49, we get 4 with a remainder of 39.
Record the quotient 4 as the next digit in the result. 
Result so far: 1654.0
Subtract 196 from 235 to get 39.
Take the next digit (5) from the dividend and append it to 39, then repeat: 395 / 49

Moving on to step 6:
The number 49 fits into 395 8 times, leaving a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 16548.0
Subtracting 392 from 395 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
If we divide 30 by 49, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 16548.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
When dividing 300 by 49, we get 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 16548.06
Deduct 294 from 300 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
The number 49 fits into 60 1 times, leaving a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 16548.061
If we subtract 49 from 60, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 10:
The number 49 fits into 110 2 times, leaving a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 16548.0612
If we subtract 98 from 110, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 11:
49 goes into 120 2 times with a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 16548.06122
Subtracting 98 from 120 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

After the division, we end up with 16548.06122 and a remainder of 2.2e-05.
