We divide 422639 by 66
We're looking to find how many times 66 goes into 422639.

On to step 1:
The number 66 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 66

Going ahead to step 2:
When dividing 42 by 66, we get 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Grab the next digit (2) from the dividend, add it to 42, then carry on: 422 / 66

Going ahead to step 3:
66 goes into 422 6 times with a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 396 from 422, we get 26.
Bring next digit (6) of the dividend behind the 26 and repeat the process: 266 / 66

Step 4:
266 divided by 66 is 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 64.0
The remainder is 2 after subtracting 264 from 266.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 66

Moving on to step 5:
23 divided by 66 is 0 with a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 640.0
Deduct 0 from 23 and we're left with 23.
Include the next digit (9) from the dividend after 23, then repeat: 239 / 66

Step 6:
If we divide 239 by 66, we get 3 and a remainder of 41.
The number 3 becomes the next digit in our result. 
Result so far: 6403.0
If we subtract 198 from 239, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 7:
66 goes into 410 6 times with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 6403.6
Subtract 396 from 410 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
66 goes into 140 2 times with a remainder of 8.
The next digit of our result is 2. 
Result so far: 6403.62
If we subtract 132 from 140, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
The number 66 fits into 80 1 times, leaving a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 6403.621
If we take 66 away from 80, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 10:
140 divided by 66 is 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 6403.6212
The remainder is 8 after subtracting 132 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
66 can be fit into 80 1 times, resulting in a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 6403.62121
Subtracting 66 from 80 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 12:
66 can be fit into 140 2 times, resulting in a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 6403.621212
The remainder is 8 after subtracting 132 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 13:
When dividing 80 by 66, we get 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 6403.6212121
If we take 66 away from 80, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 14:
140 divided by 66 is 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 6403.62121212
Subtract 132 from 140 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 6403.62121212 with a remainder of 8e-09.
