40693689 divided by 509 
We want to figure out the number of times 40693689 can be divided by 509.

Advancing to step 1:
4 divided by 509 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 509

Moving on to step 2:
When dividing 40 by 509, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Append the next digit (6) from the dividend to 40 and continue with: 406 / 509

Advancing to step 3:
509 can be fit into 406 0 times, resulting in a remainder of 406.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 406, we get 406.
Fetch the next digit (9) from the dividend, attach it to 406 and continue: 4069 / 509

Let's proceed to step 4:
The number 509 fits into 4069 7 times, leaving a remainder of 506.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 3563 from 4069 and we're left with 506.
Include the next digit (3) from the dividend after 506, then repeat: 5063 / 509

Let's proceed to step 5:
5063 divided by 509 is 9 with a remainder of 482.
The next digit of our result is 9. 
Result so far: 79.0
The remainder is 482 after subtracting 4581 from 5063.
Append the next digit (6) from the dividend to 482 and continue with: 4826 / 509

On to step 6:
4826 divided by 509 is 9 with a remainder of 245.
Use 9 as the next digit of our solution. 
Result so far: 799.0
The remainder is 245 after subtracting 4581 from 4826.
Include the next digit (8) from the dividend after 245, then repeat: 2458 / 509

Going ahead to step 7:
The number 509 fits into 2458 4 times, leaving a remainder of 422.
Write down 4 as next digit of the result. 
Result so far: 7994.0
The remainder is 422 after subtracting 2036 from 2458.
Bring next digit (9) of the dividend behind the 422 and repeat the process: 4229 / 509

On to step 8:
When dividing 4229 by 509, we get 8 with a remainder of 157.
Record the quotient 8 as the next digit in the result. 
Result so far: 79948.0
If we subtract 4072 from 4229, we get 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Moving on to step 9:
1570 divided by 509 is 3 with a remainder of 43.
Write down 3 as next digit of the result. 
Result so far: 79948.3
The remainder is 43 after subtracting 1527 from 1570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 10:
If we divide 430 by 509, we get 0 and a remainder of 430.
Use 0 as the next digit of our solution. 
Result so far: 79948.3
The remainder is 430 after subtracting 0 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Going ahead to step 11:
If we divide 4300 by 509, we get 8 and a remainder of 228.
The next digit of our result is 8. 
Result so far: 79948.308
The remainder is 228 after subtracting 4072 from 4300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Going ahead to step 12:
If we divide 2280 by 509, we get 4 and a remainder of 244.
Use 4 as the next digit of our solution. 
Result so far: 79948.3084
Deduct 2036 from 2280 and we're left with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Going ahead to step 13:
If we divide 2440 by 509, we get 4 and a remainder of 404.
Record the quotient 4 as the next digit in the result. 
Result so far: 79948.30844
If we take 2036 away from 2440, we end up with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

After the division, we end up with 79948.30844 and a remainder of 0.000404.
