We're dividing 355470 by 54 
Let's see how many times 54 fits into 355470.

Let's proceed to step 1:
3 divided by 54 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 54

On to step 2:
When dividing 35 by 54, we get 0 with a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Grab the next digit (5) from the dividend, add it to 35, then carry on: 355 / 54

Moving on to step 3:
The number 54 fits into 355 6 times, leaving a remainder of 31.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 324 from 355, we get 31.
Take the next digit (4) from the dividend and append it to 31, then repeat: 314 / 54

Let's proceed to step 4:
The number 54 fits into 314 5 times, leaving a remainder of 44.
Put 5 as the next digit of the answer. 
Result so far: 65.0
The remainder is 44 after subtracting 270 from 314.
Append the next digit (7) from the dividend to 44 and continue with: 447 / 54

Let's proceed to step 5:
54 can be fit into 447 8 times, resulting in a remainder of 15.
Put 8 as the next digit of the answer. 
Result so far: 658.0
The remainder is 15 after subtracting 432 from 447.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 54

On to step 6:
54 goes into 150 2 times with a remainder of 42.
Use 2 as the next digit of our solution. 
Result so far: 6582.0
The remainder is 42 after subtracting 108 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 7:
54 goes into 420 7 times with a remainder of 42.
Use 7 as the next digit of our solution. 
Result so far: 6582.7
If we take 378 away from 420, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 8:
420 divided by 54 is 7 with a remainder of 42.
The next digit of our result is 7. 
Result so far: 6582.77
If we subtract 378 from 420, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

After the division, we end up with 6582.77 and a remainder of 0.042.
