We look at the division of 423744 by 66 
Let's see how many times 66 fits into 423744.

Going ahead to step 1:
66 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 66

Let's proceed to step 2:
If we divide 42 by 66, we get 0 and a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Grab the next digit (3) from the dividend, add it to 42, then carry on: 423 / 66

Advancing to step 3:
If we divide 423 by 66, we get 6 and a remainder of 27.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 27 after subtracting 396 from 423.
Grab the next digit (7) from the dividend, add it to 27, then carry on: 277 / 66

On to step 4:
66 can be fit into 277 4 times, resulting in a remainder of 13.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
Subtract 264 from 277 to get 13.
Fetch the next digit (4) from the dividend, attach it to 13 and continue: 134 / 66

Going ahead to step 5:
When dividing 134 by 66, we get 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 642.0
Deduct 132 from 134 and we're left with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 66

On to step 6:
66 can be fit into 24 0 times, resulting in a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 6420.0
If we take 0 away from 24, we end up 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.

Moving on to step 7:
If we divide 240 by 66, we get 3 and a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 6420.3
Subtracting 198 from 240 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.

Step 8:
66 can be fit into 420 6 times, resulting in a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 6420.36
Subtract 396 from 420 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
If we divide 240 by 66, we get 3 and a remainder of 42.
The next digit of our result is 3. 
Result so far: 6420.363
Deduct 198 from 240 and we're left 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.

Step 10:
66 goes into 420 6 times with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 6420.3636
If we take 396 away from 420, we end up 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.

Going ahead to step 11:
66 goes into 240 3 times with a remainder of 42.
The next digit of our result is 3. 
Result so far: 6420.36363
Deduct 198 from 240 and we're left 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.

Going ahead to step 12:
420 divided by 66 is 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 6420.363636
If we take 396 away from 420, we end up 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.

Going ahead to step 13:
66 can be fit into 240 3 times, resulting in a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 6420.3636363
Subtract 198 from 240 to 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 14:
If we divide 420 by 66, we get 6 and a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 6420.36363636
If we subtract 396 from 420, we get 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 quotient of the division is 6420.36363636, and the remainder is 2.4e-08.
