We're dividing 661665 by 54 
Our goal is to divide 661665 by 54.

Let's proceed to step 1:
If we divide 6 by 54, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 54

Let's proceed to step 2:
54 goes into 66 1 times with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 12 after subtracting 54 from 66.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 54

Step 3:
54 goes into 121 2 times with a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 108 from 121 to get 13.
Grab the next digit (6) from the dividend, add it to 13, then carry on: 136 / 54

Step 4:
54 goes into 136 2 times with a remainder of 28.
The next digit of our result is 2. 
Result so far: 122.0
Deduct 108 from 136 and we're left with 28.
Take the next digit (6) from the dividend and append it to 28, then repeat: 286 / 54

Advancing to step 5:
54 can be fit into 286 5 times, resulting in a remainder of 16.
Use 5 as the next digit of our solution. 
Result so far: 1225.0
Subtracting 270 from 286 leaves us with 16.
Fetch the next digit (5) from the dividend, attach it to 16 and continue: 165 / 54

Step 6:
The number 54 fits into 165 3 times, leaving a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 12253.0
Deduct 162 from 165 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
If we divide 30 by 54, we get 0 and a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 12253.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
54 can be fit into 300 5 times, resulting in a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 12253.05
Subtracting 270 from 300 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
The number 54 fits into 300 5 times, leaving a remainder of 30.
The next digit of our result is 5. 
Result so far: 12253.055
If we take 270 away from 300, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

In conclusion, the division gives 12253.055 with a balance of 0.003.
