We're dividing 50143363 by 743 
The aim is to understand the frequency of 743 in 50143363.

Let's proceed to step 1:
743 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 743

Advancing to step 2:
If we divide 50 by 743, we get 0 and a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 50 and we're left with 50.
Include the next digit (1) from the dividend after 50, then repeat: 501 / 743

Moving on to step 3:
When dividing 501 by 743, we get 0 with a remainder of 501.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 501, we get 501.
Fetch the next digit (4) from the dividend, attach it to 501 and continue: 5014 / 743

Moving on to step 4:
743 can be fit into 5014 6 times, resulting in a remainder of 556.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 4458 from 5014 leaves us with 556.
Bring next digit (3) of the dividend behind the 556 and repeat the process: 5563 / 743

On to step 5:
743 can be fit into 5563 7 times, resulting in a remainder of 362.
Use 7 as the next digit of our solution. 
Result so far: 67.0
If we subtract 5201 from 5563, we get 362.
Fetch the next digit (3) from the dividend, attach it to 362 and continue: 3623 / 743

Moving on to step 6:
3623 divided by 743 is 4 with a remainder of 651.
Record the quotient 4 as the next digit in the result. 
Result so far: 674.0
Subtracting 2972 from 3623 leaves us with 651.
Bring next digit (6) of the dividend behind the 651 and repeat the process: 6516 / 743

Moving on to step 7:
743 can be fit into 6516 8 times, resulting in a remainder of 572.
Use 8 as the next digit of our solution. 
Result so far: 6748.0
If we take 5944 away from 6516, we end up with 572.
Append the next digit (3) from the dividend to 572 and continue with: 5723 / 743

Advancing to step 8:
The number 743 fits into 5723 7 times, leaving a remainder of 522.
Use 7 as the next digit of our solution. 
Result so far: 67487.0
Subtract 5201 from 5723 to get 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

On to step 9:
5220 divided by 743 is 7 with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 67487.7
Deduct 5201 from 5220 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.

On to step 10:
190 divided by 743 is 0 with a remainder of 190.
The next digit of our result is 0. 
Result so far: 67487.7
Subtract 0 from 190 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 11:
743 can be fit into 1900 2 times, resulting in a remainder of 414.
The next digit of our result is 2. 
Result so far: 67487.702
Subtracting 1486 from 1900 leaves us with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Let's proceed to step 12:
4140 divided by 743 is 5 with a remainder of 425.
Put 5 as the next digit of the answer. 
Result so far: 67487.7025
Subtract 3715 from 4140 to get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Let's proceed to step 13:
If we divide 4250 by 743, we get 5 and a remainder of 535.
Record the quotient 5 as the next digit in the result. 
Result so far: 67487.70255
If we subtract 3715 from 4250, we get 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

After the division, we end up with 67487.70255 and a remainder of 0.000535.
