Let's divide 4878309 by 186
The aim is to understand the frequency of 186 in 4878309.

Step 1:
186 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 186

Going ahead to step 2:
186 can be fit into 48 0 times, resulting in a remainder of 48.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 48 to get 48.
Fetch the next digit (7) from the dividend, attach it to 48 and continue: 487 / 186

On to step 3:
If we divide 487 by 186, we get 2 and a remainder of 115.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 372 from 487 to get 115.
Append the next digit (8) from the dividend to 115 and continue with: 1158 / 186

Advancing to step 4:
1158 divided by 186 is 6 with a remainder of 42.
Use 6 as the next digit of our solution. 
Result so far: 26.0
Subtract 1116 from 1158 to get 42.
Grab the next digit (3) from the dividend, add it to 42, then carry on: 423 / 186

Going ahead to step 5:
423 divided by 186 is 2 with a remainder of 51.
Write down 2 as next digit of the result. 
Result so far: 262.0
Deduct 372 from 423 and we're left with 51.
Append the next digit (0) from the dividend to 51 and continue with: 510 / 186

Going ahead to step 6:
When dividing 510 by 186, we get 2 with a remainder of 138.
Write down 2 as next digit of the result. 
Result so far: 2622.0
If we subtract 372 from 510, we get 138.
Bring next digit (9) of the dividend behind the 138 and repeat the process: 1389 / 186

Going ahead to step 7:
The number 186 fits into 1389 7 times, leaving a remainder of 87.
Use 7 as the next digit of our solution. 
Result so far: 26227.0
The remainder is 87 after subtracting 1302 from 1389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Step 8:
If we divide 870 by 186, we get 4 and a remainder of 126.
Put 4 as the next digit of the answer. 
Result so far: 26227.4
Subtract 744 from 870 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

On to step 9:
If we divide 1260 by 186, we get 6 and a remainder of 144.
The number 6 becomes the next digit in our result. 
Result so far: 26227.46
If we take 1116 away from 1260, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 10:
If we divide 1440 by 186, we get 7 and a remainder of 138.
The next digit of our result is 7. 
Result so far: 26227.467
Subtract 1302 from 1440 to get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Advancing to step 11:
The number 186 fits into 1380 7 times, leaving a remainder of 78.
The next digit of our result is 7. 
Result so far: 26227.4677
The remainder is 78 after subtracting 1302 from 1380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Our division results in 26227.4677 with a remaining 0.00078.
