70168 ÷ 90 
We're looking to find how many times 90 goes into 70168.

Moving on to step 1:
When dividing 7 by 90, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 90

Let's proceed to step 2:
If we divide 70 by 90, we get 0 and a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Grab the next digit (1) from the dividend, add it to 70, then carry on: 701 / 90

Let's proceed to step 3:
701 divided by 90 is 7 with a remainder of 71.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 71 after subtracting 630 from 701.
Fetch the next digit (6) from the dividend, attach it to 71 and continue: 716 / 90

On to step 4:
716 divided by 90 is 7 with a remainder of 86.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
Subtract 630 from 716 to get 86.
Bring next digit (8) of the dividend behind the 86 and repeat the process: 868 / 90

On to step 5:
90 goes into 868 9 times with a remainder of 58.
The next digit of our result is 9. 
Result so far: 779.0
Deduct 810 from 868 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 6:
90 goes into 580 6 times with a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 779.6
If we subtract 540 from 580, we 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.

Advancing to step 7:
90 goes into 400 4 times with a remainder of 40.
The next digit of our result is 4. 
Result so far: 779.64
Subtracting 360 from 400 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:
90 goes into 400 4 times with a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 779.644
Deduct 360 from 400 and we're left 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.

The final outcome is 779.644, with a leftover of 0.004.
