666456 ÷ 54 
Let's see how many times 54 fits into 666456.

Let's proceed to step 1:
The number 54 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 54

On to step 2:
If we divide 66 by 54, we get 1 and a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 54 away from 66, we end up with 12.
Fetch the next digit (6) from the dividend, attach it to 12 and continue: 126 / 54

Step 3:
When dividing 126 by 54, we get 2 with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 108 from 126, we get 18.
Take the next digit (4) from the dividend and append it to 18, then repeat: 184 / 54

Step 4:
The number 54 fits into 184 3 times, leaving a remainder of 22.
The next digit of our result is 3. 
Result so far: 123.0
If we take 162 away from 184, we end up with 22.
Take the next digit (5) from the dividend and append it to 22, then repeat: 225 / 54

On to step 5:
225 divided by 54 is 4 with a remainder of 9.
The next digit of our result is 4. 
Result so far: 1234.0
If we subtract 216 from 225, we get 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 54

Advancing to step 6:
54 goes into 96 1 times with a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 12341.0
If we subtract 54 from 96, 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.

Let's proceed to step 7:
When dividing 420 by 54, we get 7 with a remainder of 42.
Record the quotient 7 as the next digit in the result. 
Result so far: 12341.7
Subtracting 378 from 420 leaves us 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.

Let's proceed to step 8:
54 goes into 420 7 times with a remainder of 42.
Record the quotient 7 as the next digit in the result. 
Result so far: 12341.77
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.

The quotient of the division is 12341.77, and the remainder is 0.042.
