We look at the division of 802409 by 54 
We're looking to find how many times 54 goes into 802409.

Step 1:
If we divide 8 by 54, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 54

Advancing to step 2:
If we divide 80 by 54, we get 1 and a remainder of 26.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 26 after subtracting 54 from 80.
Fetch the next digit (2) from the dividend, attach it to 26 and continue: 262 / 54

Moving on to step 3:
When dividing 262 by 54, we get 4 with a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we subtract 216 from 262, we get 46.
Take the next digit (4) from the dividend and append it to 46, then repeat: 464 / 54

Step 4:
54 can be fit into 464 8 times, resulting in a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 148.0
The remainder is 32 after subtracting 432 from 464.
Append the next digit (0) from the dividend to 32 and continue with: 320 / 54

Step 5:
54 goes into 320 5 times with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 1485.0
Subtracting 270 from 320 leaves us with 50.
Bring next digit (9) of the dividend behind the 50 and repeat the process: 509 / 54

Going ahead to step 6:
When dividing 509 by 54, we get 9 with a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 14859.0
Subtracting 486 from 509 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
The number 54 fits into 230 4 times, leaving a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 14859.4
Subtract 216 from 230 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
54 can be fit into 140 2 times, resulting in a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 14859.42
The remainder is 32 after subtracting 108 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 9:
If we divide 320 by 54, we get 5 and a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 14859.425
If we subtract 270 from 320, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 10:
54 can be fit into 500 9 times, resulting in a remainder of 14.
The next digit of our result is 9. 
Result so far: 14859.4259
Subtracting 486 from 500 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 11:
54 can be fit into 140 2 times, resulting in a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 14859.42592
Subtract 108 from 140 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 12:
If we divide 320 by 54, we get 5 and a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 14859.425925
The remainder is 50 after subtracting 270 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 13:
When dividing 500 by 54, we get 9 with a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 14859.4259259
Subtract 486 from 500 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 14:
The number 54 fits into 140 2 times, leaving a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 14859.42592592
If we subtract 108 from 140, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 14859.42592592 with a remaining 3.2e-08.
