638837 ÷ 10 
We want to divide 638837 by 10.

On to step 1:
The number 10 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 10

On to step 2:
The number 10 fits into 63 6 times, leaving a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 3 after subtracting 60 from 63.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 10

Advancing to step 3:
38 divided by 10 is 3 with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 63.0
Deduct 30 from 38 and we're left with 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 10

On to step 4:
88 divided by 10 is 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 638.0
The remainder is 8 after subtracting 80 from 88.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 10

Step 5:
10 can be fit into 83 8 times, resulting in a remainder of 3.
The next digit of our result is 8. 
Result so far: 6388.0
Deduct 80 from 83 and we're left with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 10

Advancing to step 6:
The number 10 fits into 37 3 times, leaving a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 63883.0
If we subtract 30 from 37, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
70 divided by 10 is 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 63883.7
The remainder is 0 after subtracting 70 from 70.
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:
0 divided by 10 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 63883.7
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.

On to step 9:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 63883.7
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.

Our division results in 63883.7 with a remaining 0.0.
