We're dividing 149145 by 54 
We want to figure out the number of times 149145 can be divided by 54.

Let's proceed to step 1:
The number 54 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 54

Advancing to step 2:
The number 54 fits into 14 0 times, leaving a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Append the next digit (9) from the dividend to 14 and continue with: 149 / 54

On to step 3:
54 goes into 149 2 times with a remainder of 41.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 108 from 149, we get 41.
Take the next digit (1) from the dividend and append it to 41, then repeat: 411 / 54

Going ahead to step 4:
54 goes into 411 7 times with a remainder of 33.
Write down 7 as next digit of the result. 
Result so far: 27.0
If we take 378 away from 411, we end up with 33.
Include the next digit (4) from the dividend after 33, then repeat: 334 / 54

Moving on to step 5:
54 goes into 334 6 times with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 276.0
The remainder is 10 after subtracting 324 from 334.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 54

On to step 6:
105 divided by 54 is 1 with a remainder of 51.
The number 1 becomes the next digit in our result. 
Result so far: 2761.0
Subtract 54 from 105 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 7:
510 divided by 54 is 9 with a remainder of 24.
Put 9 as the next digit of the answer. 
Result so far: 2761.9
The remainder is 24 after subtracting 486 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 8:
If we divide 240 by 54, we get 4 and a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 2761.94
The remainder is 24 after subtracting 216 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 9:
240 divided by 54 is 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 2761.944
Subtracting 216 from 240 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 2761.944 with a remainder of 0.0024.
