We're dividing 815386 by 54 
Our goal is to divide 815386 by 54.

Going ahead to step 1:
The number 54 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 54

Advancing to step 2:
81 divided by 54 is 1 with a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 27 after subtracting 54 from 81.
Include the next digit (5) from the dividend after 27, then repeat: 275 / 54

Step 3:
54 can be fit into 275 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 5 after subtracting 270 from 275.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 54

Advancing to step 4:
53 divided by 54 is 0 with a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 150.0
Deduct 0 from 53 and we're left with 53.
Bring next digit (8) of the dividend behind the 53 and repeat the process: 538 / 54

Advancing to step 5:
54 goes into 538 9 times with a remainder of 52.
Use 9 as the next digit of our solution. 
Result so far: 1509.0
The remainder is 52 after subtracting 486 from 538.
Bring next digit (6) of the dividend behind the 52 and repeat the process: 526 / 54

On to step 6:
54 goes into 526 9 times with a remainder of 40.
Write down 9 as next digit of the result. 
Result so far: 15099.0
Deduct 486 from 526 and we're left 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.

Let's proceed to step 7:
When dividing 400 by 54, we get 7 with a remainder of 22.
The next digit of our result is 7. 
Result so far: 15099.7
If we subtract 378 from 400, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 8:
54 goes into 220 4 times with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 15099.74
Subtracting 216 from 220 leaves us with 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 9:
40 divided by 54 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 15099.74
The remainder is 40 after subtracting 0 from 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 10:
400 divided by 54 is 7 with a remainder of 22.
Record the quotient 7 as the next digit in the result. 
Result so far: 15099.7407
Subtracting 378 from 400 leaves us 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 11:
54 can be fit into 220 4 times, resulting in a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 15099.74074
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.

Moving on to step 12:
The number 54 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 15099.74074
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.

Let's proceed to step 13:
54 can be fit into 400 7 times, resulting in a remainder of 22.
Record the quotient 7 as the next digit in the result. 
Result so far: 15099.7407407
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.

Going ahead to step 14:
54 goes into 220 4 times with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 15099.74074074
Deduct 216 from 220 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 15099.74074074 with a balance of 4e-09.
