We're dividing 397638 by 10 
We want to figure out the number of times 397638 can be divided by 10.

Going ahead to step 1:
3 divided by 10 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 10

Advancing to step 2:
The number 10 fits into 39 3 times, leaving a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 30 away from 39, we end up with 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 10

On to step 3:
If we divide 97 by 10, we get 9 and a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
The remainder is 7 after subtracting 90 from 97.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 10

Advancing to step 4:
When dividing 76 by 10, we get 7 with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 397.0
Subtract 70 from 76 to get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 10

Let's proceed to step 5:
When dividing 63 by 10, we get 6 with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 3976.0
Deduct 60 from 63 and we're left with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 10

Let's proceed to step 6:
38 divided by 10 is 3 with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 39763.0
Subtract 30 from 38 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 7:
80 divided by 10 is 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 39763.8
Subtracting 80 from 80 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.

Moving on to step 8:
10 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 39763.8
Subtracting 0 from 0 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.

Let's proceed to step 9:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 39763.8
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 39763.8 and a remainder of 0.0.
