53340858 divided by 365 
The aim is to understand the frequency of 365 in 53340858.

Step 1:
When dividing 5 by 365, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 365

On to step 2:
If we divide 53 by 365, we get 0 and a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Fetch the next digit (3) from the dividend, attach it to 53 and continue: 533 / 365

Going ahead to step 3:
The number 365 fits into 533 1 times, leaving a remainder of 168.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 365 from 533 and we're left with 168.
Grab the next digit (4) from the dividend, add it to 168, then carry on: 1684 / 365

Let's proceed to step 4:
The number 365 fits into 1684 4 times, leaving a remainder of 224.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Deduct 1460 from 1684 and we're left with 224.
Include the next digit (0) from the dividend after 224, then repeat: 2240 / 365

On to step 5:
365 goes into 2240 6 times with a remainder of 50.
The next digit of our result is 6. 
Result so far: 146.0
If we subtract 2190 from 2240, we get 50.
Include the next digit (8) from the dividend after 50, then repeat: 508 / 365

Going ahead to step 6:
The number 365 fits into 508 1 times, leaving a remainder of 143.
Write down 1 as next digit of the result. 
Result so far: 1461.0
Deduct 365 from 508 and we're left with 143.
Grab the next digit (5) from the dividend, add it to 143, then carry on: 1435 / 365

Going ahead to step 7:
365 can be fit into 1435 3 times, resulting in a remainder of 340.
Use 3 as the next digit of our solution. 
Result so far: 14613.0
If we subtract 1095 from 1435, we get 340.
Fetch the next digit (8) from the dividend, attach it to 340 and continue: 3408 / 365

Let's proceed to step 8:
When dividing 3408 by 365, we get 9 with a remainder of 123.
The next digit of our result is 9. 
Result so far: 146139.0
Deduct 3285 from 3408 and we're left with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Going ahead to step 9:
1230 divided by 365 is 3 with a remainder of 135.
Write down 3 as next digit of the result. 
Result so far: 146139.3
Subtracting 1095 from 1230 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Advancing to step 10:
If we divide 1350 by 365, we get 3 and a remainder of 255.
Use 3 as the next digit of our solution. 
Result so far: 146139.33
Subtract 1095 from 1350 to get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

The final result is 146139.33 with a remainder of 0.255.
