We look at the division of 634310 by 40 
Our goal is to divide 634310 by 40.

On to step 1:
6 divided by 40 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 40

Advancing to step 2:
40 goes into 63 1 times with a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 40 away from 63, we end up with 23.
Append the next digit (4) from the dividend to 23 and continue with: 234 / 40

Going ahead to step 3:
The number 40 fits into 234 5 times, leaving a remainder of 34.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Deduct 200 from 234 and we're left with 34.
Include the next digit (3) from the dividend after 34, then repeat: 343 / 40

Moving on to step 4:
When dividing 343 by 40, we get 8 with a remainder of 23.
Write down 8 as next digit of the result. 
Result so far: 158.0
If we take 320 away from 343, we end up with 23.
Append the next digit (1) from the dividend to 23 and continue with: 231 / 40

On to step 5:
40 can be fit into 231 5 times, resulting in a remainder of 31.
Write down 5 as next digit of the result. 
Result so far: 1585.0
Deduct 200 from 231 and we're left with 31.
Bring next digit (0) of the dividend behind the 31 and repeat the process: 310 / 40

Step 6:
40 goes into 310 7 times with a remainder of 30.
Put 7 as the next digit of the answer. 
Result so far: 15857.0
Subtracting 280 from 310 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 7:
40 goes into 300 7 times with a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 15857.7
The remainder is 20 after subtracting 280 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
40 goes into 200 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 15857.75
The remainder is 0 after subtracting 200 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
0 divided by 40 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 15857.75
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.

On to step 10:
If we divide 0 by 40, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 15857.75
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.

After the division, we end up with 15857.75 and a remainder of 0.0.
