50187356 ÷ 355 
The aim is to understand the frequency of 355 in 50187356.

Let's proceed to step 1:
If we divide 5 by 355, we get 0 and 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.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 355

On to step 2:
If we divide 50 by 355, we get 0 and a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 50, we get 50.
Include the next digit (1) from the dividend after 50, then repeat: 501 / 355

Let's proceed to step 3:
When dividing 501 by 355, we get 1 with a remainder of 146.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 355 from 501 and we're left with 146.
Grab the next digit (8) from the dividend, add it to 146, then carry on: 1468 / 355

Going ahead to step 4:
1468 divided by 355 is 4 with a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 1420 from 1468, we get 48.
Include the next digit (7) from the dividend after 48, then repeat: 487 / 355

On to step 5:
If we divide 487 by 355, we get 1 and a remainder of 132.
The next digit of our result is 1. 
Result so far: 141.0
Deduct 355 from 487 and we're left with 132.
Include the next digit (3) from the dividend after 132, then repeat: 1323 / 355

Let's proceed to step 6:
355 goes into 1323 3 times with a remainder of 258.
The number 3 becomes the next digit in our result. 
Result so far: 1413.0
If we subtract 1065 from 1323, we get 258.
Bring next digit (5) of the dividend behind the 258 and repeat the process: 2585 / 355

On to step 7:
2585 divided by 355 is 7 with a remainder of 100.
Write down 7 as next digit of the result. 
Result so far: 14137.0
Subtract 2485 from 2585 to get 100.
Bring next digit (6) of the dividend behind the 100 and repeat the process: 1006 / 355

Going ahead to step 8:
355 can be fit into 1006 2 times, resulting in a remainder of 296.
Use 2 as the next digit of our solution. 
Result so far: 141372.0
If we subtract 710 from 1006, we get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Advancing to step 9:
2960 divided by 355 is 8 with a remainder of 120.
The number 8 becomes the next digit in our result. 
Result so far: 141372.8
If we subtract 2840 from 2960, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 10:
355 goes into 1200 3 times with a remainder of 135.
The number 3 becomes the next digit in our result. 
Result so far: 141372.83
Subtracting 1065 from 1200 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

On to step 11:
If we divide 1350 by 355, we get 3 and a remainder of 285.
Record the quotient 3 as the next digit in the result. 
Result so far: 141372.833
Subtracting 1065 from 1350 leaves us with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Our division results in 141372.833 with a remaining 0.0285.
