Let's divide 43688433 by 504
We want to divide 43688433 by 504.

Advancing to step 1:
504 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 504

Going ahead to step 2:
If we divide 43 by 504, we get 0 and a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Include the next digit (6) from the dividend after 43, then repeat: 436 / 504

On to step 3:
436 divided by 504 is 0 with a remainder of 436.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 436, we get 436.
Fetch the next digit (8) from the dividend, attach it to 436 and continue: 4368 / 504

Let's proceed to step 4:
504 goes into 4368 8 times with a remainder of 336.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 4032 from 4368 and we're left with 336.
Include the next digit (8) from the dividend after 336, then repeat: 3368 / 504

Step 5:
3368 divided by 504 is 6 with a remainder of 344.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
If we take 3024 away from 3368, we end up with 344.
Fetch the next digit (4) from the dividend, attach it to 344 and continue: 3444 / 504

Moving on to step 6:
If we divide 3444 by 504, we get 6 and a remainder of 420.
The number 6 becomes the next digit in our result. 
Result so far: 866.0
If we subtract 3024 from 3444, we get 420.
Bring next digit (3) of the dividend behind the 420 and repeat the process: 4203 / 504

Going ahead to step 7:
4203 divided by 504 is 8 with a remainder of 171.
The number 8 becomes the next digit in our result. 
Result so far: 8668.0
If we subtract 4032 from 4203, we get 171.
Grab the next digit (3) from the dividend, add it to 171, then carry on: 1713 / 504

Going ahead to step 8:
The number 504 fits into 1713 3 times, leaving a remainder of 201.
Write down 3 as next digit of the result. 
Result so far: 86683.0
Subtract 1512 from 1713 to get 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

On to step 9:
The number 504 fits into 2010 3 times, leaving a remainder of 498.
The next digit of our result is 3. 
Result so far: 86683.3
Deduct 1512 from 2010 and we're left with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Going ahead to step 10:
504 goes into 4980 9 times with a remainder of 444.
Use 9 as the next digit of our solution. 
Result so far: 86683.39
Deduct 4536 from 4980 and we're left with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Moving on to step 11:
The number 504 fits into 4440 8 times, leaving a remainder of 408.
Put 8 as the next digit of the answer. 
Result so far: 86683.398
The remainder is 408 after subtracting 4032 from 4440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Let's proceed to step 12:
When dividing 4080 by 504, we get 8 with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 86683.3988
The remainder is 48 after subtracting 4032 from 4080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 86683.3988, with a leftover of 0.00048.
