Let's divide 20145885 by 366
The aim is to understand the frequency of 366 in 20145885.

Advancing to step 1:
2 divided by 366 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 366

Moving on to step 2:
20 divided by 366 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Grab the next digit (1) from the dividend, add it to 20, then carry on: 201 / 366

Step 3:
201 divided by 366 is 0 with a remainder of 201.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 201 to get 201.
Fetch the next digit (4) from the dividend, attach it to 201 and continue: 2014 / 366

Going ahead to step 4:
When dividing 2014 by 366, we get 5 with a remainder of 184.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 1830 from 2014 leaves us with 184.
Bring next digit (5) of the dividend behind the 184 and repeat the process: 1845 / 366

Moving on to step 5:
If we divide 1845 by 366, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 55.0
Subtract 1830 from 1845 to get 15.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 366

Moving on to step 6:
When dividing 158 by 366, we get 0 with a remainder of 158.
Record the quotient 0 as the next digit in the result. 
Result so far: 550.0
Subtract 0 from 158 to get 158.
Include the next digit (8) from the dividend after 158, then repeat: 1588 / 366

Step 7:
366 goes into 1588 4 times with a remainder of 124.
Record the quotient 4 as the next digit in the result. 
Result so far: 5504.0
Subtract 1464 from 1588 to get 124.
Include the next digit (5) from the dividend after 124, then repeat: 1245 / 366

Going ahead to step 8:
366 goes into 1245 3 times with a remainder of 147.
Write down 3 as next digit of the result. 
Result so far: 55043.0
The remainder is 147 after subtracting 1098 from 1245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Step 9:
1470 divided by 366 is 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 55043.4
Subtract 1464 from 1470 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 10:
If we divide 60 by 366, we get 0 and a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 55043.4
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 11:
If we divide 600 by 366, we get 1 and a remainder of 234.
Use 1 as the next digit of our solution. 
Result so far: 55043.401
If we take 366 away from 600, we end up with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Step 12:
2340 divided by 366 is 6 with a remainder of 144.
Record the quotient 6 as the next digit in the result. 
Result so far: 55043.4016
Subtracting 2196 from 2340 leaves us 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.

Let's proceed to step 13:
366 goes into 1440 3 times with a remainder of 342.
Write down 3 as next digit of the result. 
Result so far: 55043.40163
Deduct 1098 from 1440 and we're left with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Step 14:
If we divide 3420 by 366, we get 9 and a remainder of 126.
Record the quotient 9 as the next digit in the result. 
Result so far: 55043.401639
If we take 3294 away from 3420, we end up with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Let's proceed to step 15:
1260 divided by 366 is 3 with a remainder of 162.
Record the quotient 3 as the next digit in the result. 
Result so far: 55043.4016393
Subtracting 1098 from 1260 leaves us with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Advancing to step 16:
If we divide 1620 by 366, we get 4 and a remainder of 156.
Put 4 as the next digit of the answer. 
Result so far: 55043.40163934
The remainder is 156 after subtracting 1464 from 1620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

After the division, we end up with 55043.40163934 and a remainder of 1.56e-07.
