858405 divided by 54 
Our goal is to divide 858405 by 54.

Going ahead to step 1:
54 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 54

On to step 2:
54 goes into 85 1 times with a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 54 away from 85, we end up with 31.
Take the next digit (8) from the dividend and append it to 31, then repeat: 318 / 54

Going ahead to step 3:
When dividing 318 by 54, we get 5 with a remainder of 48.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 270 from 318 leaves us with 48.
Fetch the next digit (4) from the dividend, attach it to 48 and continue: 484 / 54

On to step 4:
If we divide 484 by 54, we get 8 and a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 158.0
If we take 432 away from 484, we end up with 52.
Grab the next digit (0) from the dividend, add it to 52, then carry on: 520 / 54

On to step 5:
54 can be fit into 520 9 times, resulting in a remainder of 34.
Write down 9 as next digit of the result. 
Result so far: 1589.0
The remainder is 34 after subtracting 486 from 520.
Bring next digit (5) of the dividend behind the 34 and repeat the process: 345 / 54

Going ahead to step 6:
345 divided by 54 is 6 with a remainder of 21.
Put 6 as the next digit of the answer. 
Result so far: 15896.0
Deduct 324 from 345 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 7:
54 goes into 210 3 times with a remainder of 48.
Write down 3 as next digit of the result. 
Result so far: 15896.3
The remainder is 48 after subtracting 162 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 8:
54 can be fit into 480 8 times, resulting in a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 15896.38
Deduct 432 from 480 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
When dividing 480 by 54, we get 8 with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 15896.388
If we subtract 432 from 480, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 15896.388 and a remainder of 0.0048.
