636186 ÷ 40 
We want to divide 636186 by 40.

Advancing to step 1:
When dividing 6 by 40, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 40

Let's proceed to step 2:
If we divide 63 by 40, we get 1 and a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 40 from 63, we get 23.
Include the next digit (6) from the dividend after 23, then repeat: 236 / 40

On to step 3:
If we divide 236 by 40, we get 5 and a remainder of 36.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 200 from 236 and we're left with 36.
Take the next digit (1) from the dividend and append it to 36, then repeat: 361 / 40

Step 4:
If we divide 361 by 40, we get 9 and a remainder of 1.
The next digit of our result is 9. 
Result so far: 159.0
Deduct 360 from 361 and we're left with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 40

Advancing to step 5:
40 goes into 18 0 times with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 1590.0
Subtract 0 from 18 to get 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 40

On to step 6:
186 divided by 40 is 4 with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 15904.0
Deduct 160 from 186 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 7:
When dividing 260 by 40, we get 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 15904.6
Subtract 240 from 260 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
200 divided by 40 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 15904.65
Subtract 200 from 200 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.

Step 9:
0 divided by 40 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 15904.65
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 10:
40 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15904.65
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.

In conclusion, the division gives 15904.65 with a balance of 0.0.
