We divide 702640 by 18
We're looking to find how many times 18 goes into 702640.

On to step 1:
When dividing 7 by 18, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 18

Let's proceed to step 2:
70 divided by 18 is 3 with a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 16 after subtracting 54 from 70.
Fetch the next digit (2) from the dividend, attach it to 16 and continue: 162 / 18

Moving on to step 3:
The number 18 fits into 162 9 times, leaving a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 39.0
Deduct 162 from 162 and we're left with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 18

On to step 4:
If we divide 6 by 18, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 390.0
If we subtract 0 from 6, we get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 18

On to step 5:
18 can be fit into 64 3 times, resulting in a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 3903.0
If we subtract 54 from 64, we get 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 18

On to step 6:
100 divided by 18 is 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 39035.0
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
The number 18 fits into 100 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 39035.5
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
If we divide 100 by 18, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 39035.55
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 39035.55, with a leftover of 0.01.
