We're dividing 66039473 by 366 
The aim is to understand the frequency of 366 in 66039473.

Let's proceed to step 1:
366 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 366

Step 2:
66 divided by 366 is 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Fetch the next digit (0) from the dividend, attach it to 66 and continue: 660 / 366

Advancing to step 3:
660 divided by 366 is 1 with a remainder of 294.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 366 from 660, we get 294.
Grab the next digit (3) from the dividend, add it to 294, then carry on: 2943 / 366

Let's proceed to step 4:
The number 366 fits into 2943 8 times, leaving a remainder of 15.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Subtract 2928 from 2943 to get 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 366

Step 5:
If we divide 159 by 366, we get 0 and a remainder of 159.
The number 0 becomes the next digit in our result. 
Result so far: 180.0
Deduct 0 from 159 and we're left with 159.
Fetch the next digit (4) from the dividend, attach it to 159 and continue: 1594 / 366

Step 6:
366 can be fit into 1594 4 times, resulting in a remainder of 130.
Record the quotient 4 as the next digit in the result. 
Result so far: 1804.0
Subtract 1464 from 1594 to get 130.
Take the next digit (7) from the dividend and append it to 130, then repeat: 1307 / 366

Moving on to step 7:
If we divide 1307 by 366, we get 3 and a remainder of 209.
The next digit of our result is 3. 
Result so far: 18043.0
Subtracting 1098 from 1307 leaves us with 209.
Append the next digit (3) from the dividend to 209 and continue with: 2093 / 366

On to step 8:
2093 divided by 366 is 5 with a remainder of 263.
Write down 5 as next digit of the result. 
Result so far: 180435.0
Deduct 1830 from 2093 and we're left with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Advancing to step 9:
2630 divided by 366 is 7 with a remainder of 68.
Put 7 as the next digit of the answer. 
Result so far: 180435.7
Subtracting 2562 from 2630 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 10:
366 can be fit into 680 1 times, resulting in a remainder of 314.
The number 1 becomes the next digit in our result. 
Result so far: 180435.71
Subtracting 366 from 680 leaves us with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

On to step 11:
3140 divided by 366 is 8 with a remainder of 212.
The next digit of our result is 8. 
Result so far: 180435.718
Deduct 2928 from 3140 and we're left with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Let's proceed to step 12:
The number 366 fits into 2120 5 times, leaving a remainder of 290.
The number 5 becomes the next digit in our result. 
Result so far: 180435.7185
Deduct 1830 from 2120 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Going ahead to step 13:
When dividing 2900 by 366, we get 7 with a remainder of 338.
Write down 7 as next digit of the result. 
Result so far: 180435.71857
Subtract 2562 from 2900 to get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Advancing to step 14:
When dividing 3380 by 366, we get 9 with a remainder of 86.
The number 9 becomes the next digit in our result. 
Result so far: 180435.718579
Deduct 3294 from 3380 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 15:
The number 366 fits into 860 2 times, leaving a remainder of 128.
Record the quotient 2 as the next digit in the result. 
Result so far: 180435.7185792
Subtracting 732 from 860 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 16:
366 can be fit into 1280 3 times, resulting in a remainder of 182.
The number 3 becomes the next digit in our result. 
Result so far: 180435.71857923
Subtracting 1098 from 1280 leaves us with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

The quotient of the division is 180435.71857923, and the remainder is 1.82e-07.
