186339 divided by 54 
We want to divide 186339 by 54.

Advancing to step 1:
54 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 54

Going ahead to step 2:
18 divided by 54 is 0 with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 54

Going ahead to step 3:
186 divided by 54 is 3 with a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 162 from 186 leaves us with 24.
Include the next digit (3) from the dividend after 24, then repeat: 243 / 54

Moving on to step 4:
If we divide 243 by 54, we get 4 and a remainder of 27.
Use 4 as the next digit of our solution. 
Result so far: 34.0
Deduct 216 from 243 and we're left with 27.
Fetch the next digit (3) from the dividend, attach it to 27 and continue: 273 / 54

Step 5:
When dividing 273 by 54, we get 5 with a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 345.0
If we subtract 270 from 273, we get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 54

On to step 6:
When dividing 39 by 54, we get 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 3450.0
Deduct 0 from 39 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 7:
54 goes into 390 7 times with a remainder of 12.
The next digit of our result is 7. 
Result so far: 3450.7
Subtracting 378 from 390 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 8:
54 can be fit into 120 2 times, resulting in a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 3450.72
The remainder is 12 after subtracting 108 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
120 divided by 54 is 2 with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 3450.722
Subtracting 108 from 120 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 3450.722 and a remainder of 0.0012.
