50187858 ÷ 237 
The aim is to understand the frequency of 237 in 50187858.

Moving on to step 1:
When dividing 5 by 237, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 237

Advancing to step 2:
If we divide 50 by 237, we get 0 and a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 50 and we're left with 50.
Grab the next digit (1) from the dividend, add it to 50, then carry on: 501 / 237

Going ahead to step 3:
501 divided by 237 is 2 with a remainder of 27.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 474 from 501, we get 27.
Bring next digit (8) of the dividend behind the 27 and repeat the process: 278 / 237

Let's proceed to step 4:
237 goes into 278 1 times with a remainder of 41.
The next digit of our result is 1. 
Result so far: 21.0
If we subtract 237 from 278, we get 41.
Append the next digit (7) from the dividend to 41 and continue with: 417 / 237

On to step 5:
The number 237 fits into 417 1 times, leaving a remainder of 180.
Put 1 as the next digit of the answer. 
Result so far: 211.0
If we subtract 237 from 417, we get 180.
Take the next digit (8) from the dividend and append it to 180, then repeat: 1808 / 237

Advancing to step 6:
The number 237 fits into 1808 7 times, leaving a remainder of 149.
The next digit of our result is 7. 
Result so far: 2117.0
The remainder is 149 after subtracting 1659 from 1808.
Append the next digit (5) from the dividend to 149 and continue with: 1495 / 237

Let's proceed to step 7:
237 can be fit into 1495 6 times, resulting in a remainder of 73.
The next digit of our result is 6. 
Result so far: 21176.0
Deduct 1422 from 1495 and we're left with 73.
Grab the next digit (8) from the dividend, add it to 73, then carry on: 738 / 237

Advancing to step 8:
738 divided by 237 is 3 with a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 211763.0
If we subtract 711 from 738, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 9:
237 goes into 270 1 times with a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 211763.1
Subtracting 237 from 270 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 10:
330 divided by 237 is 1 with a remainder of 93.
Write down 1 as next digit of the result. 
Result so far: 211763.11
Subtract 237 from 330 to get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

After the division, we end up with 211763.11 and a remainder of 0.093.
