40690 ÷ 50 
Our goal is to divide 40690 by 50.

Advancing to step 1:
When dividing 4 by 50, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 50

On to step 2:
If we divide 40 by 50, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Fetch the next digit (6) from the dividend, attach it to 40 and continue: 406 / 50

Advancing to step 3:
50 goes into 406 8 times with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 400 from 406 and we're left with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 50

Let's proceed to step 4:
69 divided by 50 is 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 81.0
The remainder is 19 after subtracting 50 from 69.
Include the next digit (0) from the dividend after 19, then repeat: 190 / 50

Going ahead to step 5:
190 divided by 50 is 3 with a remainder of 40.
Write down 3 as next digit of the result. 
Result so far: 813.0
If we take 150 away from 190, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 6:
When dividing 400 by 50, we get 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 813.8
Deduct 400 from 400 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.

Advancing to step 7:
50 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 813.8
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.

Step 8:
0 divided by 50 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 813.8
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.

The final result is 813.8 with a remainder of 0.0.
