We're dividing 638738 by 5 
We want to divide 638738 by 5.

Advancing to step 1:
5 goes into 6 1 times with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 5 away from 6, we end up with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 5

Advancing to step 2:
13 divided by 5 is 2 with a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Deduct 10 from 13 and we're left with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 5

Advancing to step 3:
If we divide 38 by 5, we get 7 and a remainder of 3.
The next digit of our result is 7. 
Result so far: 127.0
Deduct 35 from 38 and we're left with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 5

Step 4:
If we divide 37 by 5, we get 7 and a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 1277.0
If we subtract 35 from 37, we get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 5

Moving on to step 5:
When dividing 23 by 5, we get 4 with a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 12774.0
If we take 20 away from 23, we end up with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 5

Advancing to step 6:
38 divided by 5 is 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 127747.0
If we subtract 35 from 38, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
5 can be fit into 30 6 times, resulting in a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 127747.6
If we subtract 30 from 30, 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.

Let's proceed to step 8:
5 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 127747.6
If we take 0 away from 0, we end up 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 9:
0 divided by 5 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 127747.6
Deduct 0 from 0 and we're left 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.

The final result is 127747.6 with a remainder of 0.0.
