We're dividing 491789 by 70 
We want to figure out the number of times 491789 can be divided by 70.

Moving on to step 1:
If we divide 4 by 70, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 70

Step 2:
When dividing 49 by 70, we get 0 with a remainder of 49.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 49 and we're left with 49.
Include the next digit (1) from the dividend after 49, then repeat: 491 / 70

Let's proceed to step 3:
491 divided by 70 is 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 490 away from 491, we end up with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 70

On to step 4:
If we divide 17 by 70, we get 0 and a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
Subtract 0 from 17 to get 17.
Include the next digit (8) from the dividend after 17, then repeat: 178 / 70

On to step 5:
70 goes into 178 2 times with a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 702.0
Subtracting 140 from 178 leaves us with 38.
Take the next digit (9) from the dividend and append it to 38, then repeat: 389 / 70

Step 6:
If we divide 389 by 70, we get 5 and a remainder of 39.
The number 5 becomes the next digit in our result. 
Result so far: 7025.0
The remainder is 39 after subtracting 350 from 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 7:
70 goes into 390 5 times with a remainder of 40.
The next digit of our result is 5. 
Result so far: 7025.5
Subtracting 350 from 390 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
400 divided by 70 is 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 7025.55
The remainder is 50 after subtracting 350 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The quotient of the division is 7025.55, and the remainder is 0.05.
