516835 divided by 49 
The aim is to understand the frequency of 49 in 516835.

Step 1:
5 divided by 49 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 49

Advancing to step 2:
If we divide 51 by 49, we get 1 and a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 49 away from 51, we end up with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 49

Going ahead to step 3:
26 divided by 49 is 0 with a remainder of 26.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 26, we get 26.
Include the next digit (8) from the dividend after 26, then repeat: 268 / 49

Advancing to step 4:
268 divided by 49 is 5 with a remainder of 23.
Record the quotient 5 as the next digit in the result. 
Result so far: 105.0
Deduct 245 from 268 and we're left with 23.
Take the next digit (3) from the dividend and append it to 23, then repeat: 233 / 49

Moving on to step 5:
49 goes into 233 4 times with a remainder of 37.
The next digit of our result is 4. 
Result so far: 1054.0
Deduct 196 from 233 and we're left with 37.
Append the next digit (5) from the dividend to 37 and continue with: 375 / 49

Step 6:
49 can be fit into 375 7 times, resulting in a remainder of 32.
Record the quotient 7 as the next digit in the result. 
Result so far: 10547.0
If we subtract 343 from 375, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 7:
49 can be fit into 320 6 times, resulting in a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 10547.6
Subtract 294 from 320 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 8:
49 can be fit into 260 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 10547.65
If we take 245 away from 260, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
150 divided by 49 is 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 10547.653
Deduct 147 from 150 and we're left 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.

On to step 10:
The number 49 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 10547.653
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
The number 49 fits into 300 6 times, leaving a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 10547.65306
If we subtract 294 from 300, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 12:
The number 49 fits into 60 1 times, leaving a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 10547.653061
Subtract 49 from 60 to 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.

Moving on to step 13:
If we divide 110 by 49, we get 2 and a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 10547.6530612
Subtracting 98 from 110 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 14:
49 goes into 120 2 times with a remainder of 22.
The next digit of our result is 2. 
Result so far: 10547.65306122
If we take 98 away from 120, we end up 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.

The quotient of the division is 10547.65306122, and the remainder is 2.2e-08.
