427940 divided by 66 
We want to figure out the number of times 427940 can be divided by 66.

Step 1:
4 divided by 66 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 66

Let's proceed to step 2:
When dividing 42 by 66, we get 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Bring next digit (7) of the dividend behind the 42 and repeat the process: 427 / 66

Going ahead to step 3:
If we divide 427 by 66, we get 6 and a remainder of 31.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 396 from 427, we get 31.
Bring next digit (9) of the dividend behind the 31 and repeat the process: 319 / 66

Going ahead to step 4:
319 divided by 66 is 4 with a remainder of 55.
Write down 4 as next digit of the result. 
Result so far: 64.0
The remainder is 55 after subtracting 264 from 319.
Bring next digit (4) of the dividend behind the 55 and repeat the process: 554 / 66

Going ahead to step 5:
When dividing 554 by 66, we get 8 with a remainder of 26.
Write down 8 as next digit of the result. 
Result so far: 648.0
If we subtract 528 from 554, we get 26.
Append the next digit (0) from the dividend to 26 and continue with: 260 / 66

Moving on to step 6:
The number 66 fits into 260 3 times, leaving a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 6483.0
Deduct 198 from 260 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 7:
66 goes into 620 9 times with a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 6483.9
The remainder is 26 after subtracting 594 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 8:
66 goes into 260 3 times with a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 6483.93
Deduct 198 from 260 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 9:
The number 66 fits into 620 9 times, leaving a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 6483.939
Subtract 594 from 620 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 10:
66 can be fit into 260 3 times, resulting in a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 6483.9393
If we subtract 198 from 260, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 11:
66 goes into 620 9 times with a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 6483.93939
If we subtract 594 from 620, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 12:
When dividing 260 by 66, we get 3 with a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 6483.939393
If we take 198 away from 260, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 13:
If we divide 620 by 66, we get 9 and a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 6483.9393939
Subtracting 594 from 620 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 14:
When dividing 260 by 66, we get 3 with a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 6483.93939393
If we take 198 away from 260, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

After the division, we end up with 6483.93939393 and a remainder of 6.2e-08.
