We divide 638350 by 1
Let's see how many times 1 fits into 638350.

Advancing to step 1:
1 goes into 6 6 times with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 6 from 6 to get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 1

Advancing to step 2:
1 can be fit into 3 3 times, resulting in a remainder of 0.
The next digit of our result is 3. 
Result so far: 63.0
Subtract 3 from 3 to get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 1

On to step 3:
8 divided by 1 is 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 638.0
The remainder is 0 after subtracting 8 from 8.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 1

Let's proceed to step 4:
1 can be fit into 3 3 times, resulting in a remainder of 0.
The next digit of our result is 3. 
Result so far: 6383.0
The remainder is 0 after subtracting 3 from 3.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 1

Moving on to step 5:
If we divide 5 by 1, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 63835.0
If we subtract 5 from 5, we get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 1

Let's proceed to step 6:
1 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 638350.0
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.

Advancing to step 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 638350.0
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.

On to step 8:
When dividing 0 by 1, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 638350.0
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.

In conclusion, the division gives 638350.0 with a balance of 0.0.
