42213 divided by 66 
We want to divide 42213 by 66.

On to step 1:
The number 66 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 66

On to step 2:
66 goes into 42 0 times with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Fetch the next digit (2) from the dividend, attach it to 42 and continue: 422 / 66

On to step 3:
The number 66 fits into 422 6 times, leaving a remainder of 26.
The next digit of our result is 6. 
Result so far: 6.0
If we take 396 away from 422, we end up with 26.
Bring next digit (1) of the dividend behind the 26 and repeat the process: 261 / 66

On to step 4:
The number 66 fits into 261 3 times, leaving a remainder of 63.
The number 3 becomes the next digit in our result. 
Result so far: 63.0
If we subtract 198 from 261, we get 63.
Take the next digit (3) from the dividend and append it to 63, then repeat: 633 / 66

On to step 5:
The number 66 fits into 633 9 times, leaving a remainder of 39.
The next digit of our result is 9. 
Result so far: 639.0
Deduct 594 from 633 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 6:
390 divided by 66 is 5 with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 639.5
The remainder is 60 after subtracting 330 from 390.
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 7:
600 divided by 66 is 9 with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 639.59
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.

Advancing to step 8:
When dividing 60 by 66, we get 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 639.59
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.

Advancing to step 9:
If we divide 600 by 66, we get 9 and a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 639.5909
If we subtract 594 from 600, 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.

Let's proceed to step 10:
66 can be fit into 60 0 times, resulting in a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 639.5909
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 11:
The number 66 fits into 600 9 times, leaving a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 639.590909
If we subtract 594 from 600, 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.

Going ahead to step 12:
The number 66 fits into 60 0 times, leaving a remainder of 60.
The next digit of our result is 0. 
Result so far: 639.590909
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.

Moving on to step 13:
600 divided by 66 is 9 with a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 639.59090909
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.

After the division, we end up with 639.59090909 and a remainder of 6e-09.
