We look at the division of 638690 by 68 
We want to divide 638690 by 68.

On to step 1:
The number 68 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 68

Advancing to step 2:
68 can be fit into 63 0 times, resulting in a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Include the next digit (8) from the dividend after 63, then repeat: 638 / 68

Step 3:
638 divided by 68 is 9 with a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 612 from 638, we get 26.
Grab the next digit (6) from the dividend, add it to 26, then carry on: 266 / 68

Advancing to step 4:
The number 68 fits into 266 3 times, leaving a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 93.0
If we subtract 204 from 266, we get 62.
Include the next digit (9) from the dividend after 62, then repeat: 629 / 68

Moving on to step 5:
629 divided by 68 is 9 with a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 939.0
If we take 612 away from 629, we end up with 17.
Append the next digit (0) from the dividend to 17 and continue with: 170 / 68

Going ahead to step 6:
If we divide 170 by 68, we get 2 and a remainder of 34.
The next digit of our result is 2. 
Result so far: 9392.0
The remainder is 34 after subtracting 136 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 7:
When dividing 340 by 68, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 9392.5
Subtracting 340 from 340 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
The number 68 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 9392.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
0 divided by 68 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9392.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 9392.5 with a remaining 0.0.
