We look at the division of 863599 by 54 
Let's see how many times 54 fits into 863599.

Advancing to step 1:
If we divide 8 by 54, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 54

Step 2:
86 divided by 54 is 1 with a remainder of 32.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 32 after subtracting 54 from 86.
Grab the next digit (3) from the dividend, add it to 32, then carry on: 323 / 54

On to step 3:
323 divided by 54 is 5 with a remainder of 53.
The next digit of our result is 5. 
Result so far: 15.0
If we subtract 270 from 323, we get 53.
Bring next digit (5) of the dividend behind the 53 and repeat the process: 535 / 54

Moving on to step 4:
When dividing 535 by 54, we get 9 with a remainder of 49.
The number 9 becomes the next digit in our result. 
Result so far: 159.0
Subtracting 486 from 535 leaves us with 49.
Include the next digit (9) from the dividend after 49, then repeat: 499 / 54

Moving on to step 5:
54 can be fit into 499 9 times, resulting in a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 1599.0
Subtract 486 from 499 to get 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 54

Advancing to step 6:
139 divided by 54 is 2 with a remainder of 31.
The number 2 becomes the next digit in our result. 
Result so far: 15992.0
The remainder is 31 after subtracting 108 from 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 7:
54 can be fit into 310 5 times, resulting in a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 15992.5
If we subtract 270 from 310, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 8:
54 goes into 400 7 times with a remainder of 22.
Write down 7 as next digit of the result. 
Result so far: 15992.57
If we take 378 away from 400, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 9:
54 can be fit into 220 4 times, resulting in a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 15992.574
Subtract 216 from 220 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
54 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 15992.574
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
When dividing 400 by 54, we get 7 with a remainder of 22.
The number 7 becomes the next digit in our result. 
Result so far: 15992.57407
Deduct 378 from 400 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 12:
54 can be fit into 220 4 times, resulting in a remainder of 4.
The next digit of our result is 4. 
Result so far: 15992.574074
The remainder is 4 after subtracting 216 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 13:
The number 54 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 15992.574074
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 14:
400 divided by 54 is 7 with a remainder of 22.
The number 7 becomes the next digit in our result. 
Result so far: 15992.57407407
If we take 378 away from 400, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

In conclusion, the division gives 15992.57407407 with a balance of 2.2e-08.
