We're dividing 50410198 by 424 
The aim is to understand the frequency of 424 in 50410198.

On to step 1:
If we divide 5 by 424, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 424

Advancing to step 2:
424 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 50, we get 50.
Fetch the next digit (4) from the dividend, attach it to 50 and continue: 504 / 424

Step 3:
When dividing 504 by 424, we get 1 with a remainder of 80.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 424 from 504 to get 80.
Append the next digit (1) from the dividend to 80 and continue with: 801 / 424

Advancing to step 4:
When dividing 801 by 424, we get 1 with a remainder of 377.
The next digit of our result is 1. 
Result so far: 11.0
Deduct 424 from 801 and we're left with 377.
Bring next digit (0) of the dividend behind the 377 and repeat the process: 3770 / 424

Step 5:
When dividing 3770 by 424, we get 8 with a remainder of 378.
The next digit of our result is 8. 
Result so far: 118.0
Subtracting 3392 from 3770 leaves us with 378.
Append the next digit (1) from the dividend to 378 and continue with: 3781 / 424

Going ahead to step 6:
When dividing 3781 by 424, we get 8 with a remainder of 389.
The number 8 becomes the next digit in our result. 
Result so far: 1188.0
Subtract 3392 from 3781 to get 389.
Append the next digit (9) from the dividend to 389 and continue with: 3899 / 424

On to step 7:
When dividing 3899 by 424, we get 9 with a remainder of 83.
Record the quotient 9 as the next digit in the result. 
Result so far: 11889.0
Subtracting 3816 from 3899 leaves us with 83.
Take the next digit (8) from the dividend and append it to 83, then repeat: 838 / 424

On to step 8:
When dividing 838 by 424, we get 1 with a remainder of 414.
Use 1 as the next digit of our solution. 
Result so far: 118891.0
Subtract 424 from 838 to get 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

On to step 9:
When dividing 4140 by 424, we get 9 with a remainder of 324.
Put 9 as the next digit of the answer. 
Result so far: 118891.9
If we subtract 3816 from 4140, we get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Advancing to step 10:
When dividing 3240 by 424, we get 7 with a remainder of 272.
Put 7 as the next digit of the answer. 
Result so far: 118891.97
Subtracting 2968 from 3240 leaves us with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Step 11:
2720 divided by 424 is 6 with a remainder of 176.
The number 6 becomes the next digit in our result. 
Result so far: 118891.976
If we take 2544 away from 2720, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 12:
424 can be fit into 1760 4 times, resulting in a remainder of 64.
The next digit of our result is 4. 
Result so far: 118891.9764
Subtracting 1696 from 1760 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 13:
When dividing 640 by 424, we get 1 with a remainder of 216.
Record the quotient 1 as the next digit in the result. 
Result so far: 118891.97641
If we take 424 away from 640, we end up with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Moving on to step 14:
When dividing 2160 by 424, we get 5 with a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 118891.976415
If we subtract 2120 from 2160, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 15:
424 can be fit into 400 0 times, resulting in a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 118891.976415
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 16:
424 goes into 4000 9 times with a remainder of 184.
Write down 9 as next digit of the result. 
Result so far: 118891.97641509
The remainder is 184 after subtracting 3816 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

The final result is 118891.97641509 with a remainder of 1.84e-07.
