5043084 ÷ 387 
The aim is to understand the frequency of 387 in 5043084.

Step 1:
If we divide 5 by 387, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 387

Step 2:
The number 387 fits into 50 0 times, leaving a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 50, we end up with 50.
Include the next digit (4) from the dividend after 50, then repeat: 504 / 387

Going ahead to step 3:
387 goes into 504 1 times with a remainder of 117.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 387 from 504 to get 117.
Fetch the next digit (3) from the dividend, attach it to 117 and continue: 1173 / 387

Going ahead to step 4:
387 goes into 1173 3 times with a remainder of 12.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 1161 from 1173 leaves us with 12.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 387

Advancing to step 5:
387 can be fit into 120 0 times, resulting in a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 130.0
If we subtract 0 from 120, we get 120.
Bring next digit (8) of the dividend behind the 120 and repeat the process: 1208 / 387

Moving on to step 6:
When dividing 1208 by 387, we get 3 with a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 1303.0
Subtract 1161 from 1208 to get 47.
Append the next digit (4) from the dividend to 47 and continue with: 474 / 387

Going ahead to step 7:
474 divided by 387 is 1 with a remainder of 87.
The number 1 becomes the next digit in our result. 
Result so far: 13031.0
The remainder is 87 after subtracting 387 from 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 8:
When dividing 870 by 387, we get 2 with a remainder of 96.
The next digit of our result is 2. 
Result so far: 13031.2
Subtracting 774 from 870 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 9:
387 goes into 960 2 times with a remainder of 186.
Write down 2 as next digit of the result. 
Result so far: 13031.22
If we take 774 away from 960, we end up with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Our division results in 13031.22 with a remaining 0.186.
