We're dividing 66422 by 70 
We're looking to find how many times 70 goes into 66422.

Step 1:
6 divided by 70 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 70

Going ahead to step 2:
66 divided by 70 is 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Bring next digit (4) of the dividend behind the 66 and repeat the process: 664 / 70

Let's proceed to step 3:
When dividing 664 by 70, we get 9 with a remainder of 34.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 630 from 664 leaves us with 34.
Take the next digit (2) from the dividend and append it to 34, then repeat: 342 / 70

Advancing to step 4:
70 can be fit into 342 4 times, resulting in a remainder of 62.
Use 4 as the next digit of our solution. 
Result so far: 94.0
Deduct 280 from 342 and we're left with 62.
Take the next digit (2) from the dividend and append it to 62, then repeat: 622 / 70

Advancing to step 5:
70 goes into 622 8 times with a remainder of 62.
The next digit of our result is 8. 
Result so far: 948.0
Deduct 560 from 622 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.

Going ahead to step 6:
When dividing 620 by 70, we get 8 with a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 948.8
Subtracting 560 from 620 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.

On to step 7:
70 can be fit into 600 8 times, resulting in a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 948.88
Subtract 560 from 600 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 948.88, and the remainder is 0.04.
