We look at the division of 49103713 by 73 
The aim is to understand the frequency of 73 in 49103713.

On to step 1:
73 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 73

On to step 2:
49 divided by 73 is 0 with a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 49 leaves us with 49.
Take the next digit (1) from the dividend and append it to 49, then repeat: 491 / 73

Let's proceed to step 3:
The number 73 fits into 491 6 times, leaving a remainder of 53.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 438 from 491, we get 53.
Fetch the next digit (0) from the dividend, attach it to 53 and continue: 530 / 73

On to step 4:
530 divided by 73 is 7 with a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 67.0
If we take 511 away from 530, we end up with 19.
Append the next digit (3) from the dividend to 19 and continue with: 193 / 73

Moving on to step 5:
If we divide 193 by 73, we get 2 and a remainder of 47.
Use 2 as the next digit of our solution. 
Result so far: 672.0
If we take 146 away from 193, we end up with 47.
Include the next digit (7) from the dividend after 47, then repeat: 477 / 73

On to step 6:
477 divided by 73 is 6 with a remainder of 39.
The number 6 becomes the next digit in our result. 
Result so far: 6726.0
Deduct 438 from 477 and we're left with 39.
Fetch the next digit (1) from the dividend, attach it to 39 and continue: 391 / 73

Step 7:
If we divide 391 by 73, we get 5 and a remainder of 26.
Write down 5 as next digit of the result. 
Result so far: 67265.0
The remainder is 26 after subtracting 365 from 391.
Bring next digit (3) of the dividend behind the 26 and repeat the process: 263 / 73

Advancing to step 8:
73 can be fit into 263 3 times, resulting in a remainder of 44.
The next digit of our result is 3. 
Result so far: 672653.0
Subtracting 219 from 263 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 9:
The number 73 fits into 440 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 672653.6
Deduct 438 from 440 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 10:
73 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 672653.6
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
When dividing 200 by 73, we get 2 with a remainder of 54.
Write down 2 as next digit of the result. 
Result so far: 672653.602
The remainder is 54 after subtracting 146 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 12:
When dividing 540 by 73, we get 7 with a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 672653.6027
Deduct 511 from 540 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 13:
73 can be fit into 290 3 times, resulting in a remainder of 71.
The next digit of our result is 3. 
Result so far: 672653.60273
The remainder is 71 after subtracting 219 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 14:
73 goes into 710 9 times with a remainder of 53.
Record the quotient 9 as the next digit in the result. 
Result so far: 672653.602739
If we subtract 657 from 710, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 15:
When dividing 530 by 73, we get 7 with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 672653.6027397
Deduct 511 from 530 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 16:
73 can be fit into 190 2 times, resulting in a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 672653.60273972
Subtracting 146 from 190 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Our division results in 672653.60273972 with a remaining 4.4e-08.
