642084 divided by 66 
We're looking to find how many times 66 goes into 642084.

Step 1:
66 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 66

Step 2:
When dividing 64 by 66, we get 0 with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Take the next digit (2) from the dividend and append it to 64, then repeat: 642 / 66

Step 3:
66 goes into 642 9 times with a remainder of 48.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 594 from 642 and we're left with 48.
Append the next digit (0) from the dividend to 48 and continue with: 480 / 66

Step 4:
66 can be fit into 480 7 times, resulting in a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 97.0
If we take 462 away from 480, we end up with 18.
Append the next digit (8) from the dividend to 18 and continue with: 188 / 66

Advancing to step 5:
If we divide 188 by 66, we get 2 and a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 972.0
If we take 132 away from 188, we end up with 56.
Bring next digit (4) of the dividend behind the 56 and repeat the process: 564 / 66

Advancing to step 6:
When dividing 564 by 66, we get 8 with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 9728.0
Subtracting 528 from 564 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 7:
66 goes into 360 5 times with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 9728.5
Subtracting 330 from 360 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
The number 66 fits into 300 4 times, leaving a remainder of 36.
The next digit of our result is 4. 
Result so far: 9728.54
If we take 264 away from 300, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 9:
The number 66 fits into 360 5 times, leaving a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 9728.545
The remainder is 30 after subtracting 330 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
The number 66 fits into 300 4 times, leaving a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 9728.5454
If we subtract 264 from 300, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 11:
66 goes into 360 5 times with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 9728.54545
If we take 330 away from 360, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 12:
300 divided by 66 is 4 with a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 9728.545454
Subtracting 264 from 300 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 13:
The number 66 fits into 360 5 times, leaving a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 9728.5454545
Deduct 330 from 360 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 14:
300 divided by 66 is 4 with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 9728.54545454
If we subtract 264 from 300, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Our division results in 9728.54545454 with a remaining 3.6e-08.
