70017 ÷ 90 
We want to divide 70017 by 90.

Step 1:
When dividing 7 by 90, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 90

Let's proceed to step 2:
When dividing 70 by 90, we get 0 with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Append the next digit (0) from the dividend to 70 and continue with: 700 / 90

On to step 3:
The number 90 fits into 700 7 times, leaving a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 630 away from 700, we end up with 70.
Append the next digit (1) from the dividend to 70 and continue with: 701 / 90

Going ahead to step 4:
701 divided by 90 is 7 with a remainder of 71.
The number 7 becomes the next digit in our result. 
Result so far: 77.0
The remainder is 71 after subtracting 630 from 701.
Include the next digit (7) from the dividend after 71, then repeat: 717 / 90

Advancing to step 5:
90 can be fit into 717 7 times, resulting in a remainder of 87.
Record the quotient 7 as the next digit in the result. 
Result so far: 777.0
Subtract 630 from 717 to get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Let's proceed to step 6:
90 goes into 870 9 times with a remainder of 60.
Record the quotient 9 as the next digit in the result. 
Result so far: 777.9
If we subtract 810 from 870, we 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.

Going ahead to step 7:
The number 90 fits into 600 6 times, leaving a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 777.96
If we subtract 540 from 600, we 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.

Step 8:
If we divide 600 by 90, we get 6 and a remainder of 60.
The next digit of our result is 6. 
Result so far: 777.966
The remainder is 60 after subtracting 540 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final outcome is 777.966, with a leftover of 0.006.
