81644415 divided by 365 
The aim is to understand the frequency of 365 in 81644415.

Advancing to step 1:
365 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 365

Step 2:
365 goes into 81 0 times with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Take the next digit (6) from the dividend and append it to 81, then repeat: 816 / 365

Step 3:
365 goes into 816 2 times with a remainder of 86.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 730 from 816 leaves us with 86.
Take the next digit (4) from the dividend and append it to 86, then repeat: 864 / 365

On to step 4:
If we divide 864 by 365, we get 2 and a remainder of 134.
Use 2 as the next digit of our solution. 
Result so far: 22.0
The remainder is 134 after subtracting 730 from 864.
Fetch the next digit (4) from the dividend, attach it to 134 and continue: 1344 / 365

On to step 5:
365 can be fit into 1344 3 times, resulting in a remainder of 249.
The next digit of our result is 3. 
Result so far: 223.0
If we take 1095 away from 1344, we end up with 249.
Append the next digit (4) from the dividend to 249 and continue with: 2494 / 365

Moving on to step 6:
If we divide 2494 by 365, we get 6 and a remainder of 304.
Use 6 as the next digit of our solution. 
Result so far: 2236.0
Deduct 2190 from 2494 and we're left with 304.
Take the next digit (1) from the dividend and append it to 304, then repeat: 3041 / 365

On to step 7:
365 goes into 3041 8 times with a remainder of 121.
The next digit of our result is 8. 
Result so far: 22368.0
Subtract 2920 from 3041 to get 121.
Grab the next digit (5) from the dividend, add it to 121, then carry on: 1215 / 365

Advancing to step 8:
365 goes into 1215 3 times with a remainder of 120.
Write down 3 as next digit of the result. 
Result so far: 223683.0
The remainder is 120 after subtracting 1095 from 1215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 9:
The number 365 fits into 1200 3 times, leaving a remainder of 105.
The next digit of our result is 3. 
Result so far: 223683.3
If we take 1095 away from 1200, we end up with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Step 10:
365 goes into 1050 2 times with a remainder of 320.
Write down 2 as next digit of the result. 
Result so far: 223683.32
The remainder is 320 after subtracting 730 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 11:
When dividing 3200 by 365, we get 8 with a remainder of 280.
Use 8 as the next digit of our solution. 
Result so far: 223683.328
Subtracting 2920 from 3200 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 12:
When dividing 2800 by 365, we get 7 with a remainder of 245.
The number 7 becomes the next digit in our result. 
Result so far: 223683.3287
If we take 2555 away from 2800, we end up with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

On to step 13:
The number 365 fits into 2450 6 times, leaving a remainder of 260.
Record the quotient 6 as the next digit in the result. 
Result so far: 223683.32876
Subtract 2190 from 2450 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 14:
When dividing 2600 by 365, we get 7 with a remainder of 45.
The number 7 becomes the next digit in our result. 
Result so far: 223683.328767
The remainder is 45 after subtracting 2555 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 15:
365 goes into 450 1 times with a remainder of 85.
The next digit of our result is 1. 
Result so far: 223683.3287671
The remainder is 85 after subtracting 365 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 16:
When dividing 850 by 365, we get 2 with a remainder of 120.
Put 2 as the next digit of the answer. 
Result so far: 223683.32876712
Deduct 730 from 850 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The final result is 223683.32876712 with a remainder of 1.2e-07.
