424254 divided by 66 
We want to divide 424254 by 66.

Moving on to step 1:
66 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 66

Let's proceed to step 2:
If we divide 42 by 66, we get 0 and a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Grab the next digit (4) from the dividend, add it to 42, then carry on: 424 / 66

Step 3:
424 divided by 66 is 6 with a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 396 from 424, we get 28.
Fetch the next digit (2) from the dividend, attach it to 28 and continue: 282 / 66

Advancing to step 4:
The number 66 fits into 282 4 times, leaving a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
The remainder is 18 after subtracting 264 from 282.
Bring next digit (5) of the dividend behind the 18 and repeat the process: 185 / 66

Let's proceed to step 5:
The number 66 fits into 185 2 times, leaving a remainder of 53.
The next digit of our result is 2. 
Result so far: 642.0
If we subtract 132 from 185, we get 53.
Grab the next digit (4) from the dividend, add it to 53, then carry on: 534 / 66

Step 6:
66 goes into 534 8 times with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 6428.0
If we subtract 528 from 534, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
66 can be fit into 60 0 times, resulting in a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 6428.0
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 8:
66 goes into 600 9 times with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 6428.09
The remainder is 6 after subtracting 594 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
If we divide 60 by 66, we get 0 and a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 6428.09
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 10:
If we divide 600 by 66, we get 9 and a remainder of 6.
The next digit of our result is 9. 
Result so far: 6428.0909
If we take 594 away from 600, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 11:
60 divided by 66 is 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 6428.0909
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 12:
When dividing 600 by 66, we get 9 with a remainder of 6.
The next digit of our result is 9. 
Result so far: 6428.090909
Deduct 594 from 600 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 13:
The number 66 fits into 60 0 times, leaving a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 6428.090909
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 14:
66 can be fit into 600 9 times, resulting in a remainder of 6.
The next digit of our result is 9. 
Result so far: 6428.09090909
Deduct 594 from 600 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 6428.09090909 with a remainder of 6e-09.
