708638 ÷ 18 
We're looking to find how many times 18 goes into 708638.

Advancing to step 1:
When dividing 7 by 18, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 18

Moving on to step 2:
18 goes into 70 3 times with a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 54 away from 70, we end up with 16.
Take the next digit (8) from the dividend and append it to 16, then repeat: 168 / 18

Going ahead to step 3:
18 can be fit into 168 9 times, resulting in a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
If we take 162 away from 168, we end up with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 18

On to step 4:
If we divide 66 by 18, we get 3 and a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 393.0
Subtracting 54 from 66 leaves us with 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 18

Moving on to step 5:
18 goes into 123 6 times with a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 3936.0
If we take 108 away from 123, we end up with 15.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 18

Moving on to step 6:
The number 18 fits into 158 8 times, leaving a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 39368.0
Deduct 144 from 158 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 7:
When dividing 140 by 18, we get 7 with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 39368.7
The remainder is 14 after subtracting 126 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
18 can be fit into 140 7 times, resulting in a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 39368.77
If we take 126 away from 140, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

In conclusion, the division gives 39368.77 with a balance of 0.014.
