We're dividing 66157690 by 365 
The aim is to understand the frequency of 365 in 66157690.

On to step 1:
365 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 365

Advancing to step 2:
365 goes into 66 0 times with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Include the next digit (1) from the dividend after 66, then repeat: 661 / 365

Moving on to step 3:
365 goes into 661 1 times with a remainder of 296.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 365 from 661 to get 296.
Take the next digit (5) from the dividend and append it to 296, then repeat: 2965 / 365

Moving on to step 4:
365 can be fit into 2965 8 times, resulting in a remainder of 45.
The next digit of our result is 8. 
Result so far: 18.0
If we take 2920 away from 2965, we end up with 45.
Bring next digit (7) of the dividend behind the 45 and repeat the process: 457 / 365

Moving on to step 5:
457 divided by 365 is 1 with a remainder of 92.
Put 1 as the next digit of the answer. 
Result so far: 181.0
If we take 365 away from 457, we end up with 92.
Grab the next digit (6) from the dividend, add it to 92, then carry on: 926 / 365

Step 6:
926 divided by 365 is 2 with a remainder of 196.
Write down 2 as next digit of the result. 
Result so far: 1812.0
If we subtract 730 from 926, we get 196.
Take the next digit (9) from the dividend and append it to 196, then repeat: 1969 / 365

Step 7:
365 goes into 1969 5 times with a remainder of 144.
The number 5 becomes the next digit in our result. 
Result so far: 18125.0
Subtracting 1825 from 1969 leaves us with 144.
Take the next digit (0) from the dividend and append it to 144, then repeat: 1440 / 365

Let's proceed to step 8:
1440 divided by 365 is 3 with a remainder of 345.
Write down 3 as next digit of the result. 
Result so far: 181253.0
Deduct 1095 from 1440 and we're left with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

On to step 9:
When dividing 3450 by 365, we get 9 with a remainder of 165.
Write down 9 as next digit of the result. 
Result so far: 181253.9
Deduct 3285 from 3450 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Advancing to step 10:
365 can be fit into 1650 4 times, resulting in a remainder of 190.
Put 4 as the next digit of the answer. 
Result so far: 181253.94
The remainder is 190 after subtracting 1460 from 1650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 11:
The number 365 fits into 1900 5 times, leaving a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 181253.945
Deduct 1825 from 1900 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 12:
The number 365 fits into 750 2 times, leaving a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 181253.9452
The remainder is 20 after subtracting 730 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 13:
The number 365 fits into 200 0 times, leaving a remainder of 200.
The next digit of our result is 0. 
Result so far: 181253.9452
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 14:
When dividing 2000 by 365, we get 5 with a remainder of 175.
The next digit of our result is 5. 
Result so far: 181253.945205
Deduct 1825 from 2000 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

On to step 15:
When dividing 1750 by 365, we get 4 with a remainder of 290.
Record the quotient 4 as the next digit in the result. 
Result so far: 181253.9452054
Deduct 1460 from 1750 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.

Step 16:
If we divide 2900 by 365, we get 7 and a remainder of 345.
Use 7 as the next digit of our solution. 
Result so far: 181253.94520547
Subtracting 2555 from 2900 leaves us with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Our division results in 181253.94520547 with a remaining 3.45e-07.
