40542917 ÷ 504 
We want to divide 40542917 by 504.

Let's proceed to step 1:
4 divided by 504 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 504

Step 2:
504 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Grab the next digit (5) from the dividend, add it to 40, then carry on: 405 / 504

On to step 3:
504 can be fit into 405 0 times, resulting in a remainder of 405.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 405 leaves us with 405.
Append the next digit (4) from the dividend to 405 and continue with: 4054 / 504

Advancing to step 4:
When dividing 4054 by 504, we get 8 with a remainder of 22.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 4032 from 4054, we get 22.
Grab the next digit (2) from the dividend, add it to 22, then carry on: 222 / 504

On to step 5:
When dividing 222 by 504, we get 0 with a remainder of 222.
Write down 0 as next digit of the result. 
Result so far: 80.0
Subtracting 0 from 222 leaves us with 222.
Append the next digit (9) from the dividend to 222 and continue with: 2229 / 504

Going ahead to step 6:
If we divide 2229 by 504, we get 4 and a remainder of 213.
Put 4 as the next digit of the answer. 
Result so far: 804.0
Subtract 2016 from 2229 to get 213.
Take the next digit (1) from the dividend and append it to 213, then repeat: 2131 / 504

Moving on to step 7:
504 goes into 2131 4 times with a remainder of 115.
The number 4 becomes the next digit in our result. 
Result so far: 8044.0
Subtract 2016 from 2131 to get 115.
Include the next digit (7) from the dividend after 115, then repeat: 1157 / 504

Moving on to step 8:
504 goes into 1157 2 times with a remainder of 149.
Record the quotient 2 as the next digit in the result. 
Result so far: 80442.0
Subtracting 1008 from 1157 leaves us with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Going ahead to step 9:
The number 504 fits into 1490 2 times, leaving a remainder of 482.
Use 2 as the next digit of our solution. 
Result so far: 80442.2
Deduct 1008 from 1490 and we're left with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Let's proceed to step 10:
504 can be fit into 4820 9 times, resulting in a remainder of 284.
The number 9 becomes the next digit in our result. 
Result so far: 80442.29
The remainder is 284 after subtracting 4536 from 4820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Advancing to step 11:
The number 504 fits into 2840 5 times, leaving a remainder of 320.
The number 5 becomes the next digit in our result. 
Result so far: 80442.295
The remainder is 320 after subtracting 2520 from 2840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 12:
504 can be fit into 3200 6 times, resulting in a remainder of 176.
The number 6 becomes the next digit in our result. 
Result so far: 80442.2956
If we take 3024 away from 3200, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Moving on to step 13:
504 goes into 1760 3 times with a remainder of 248.
The next digit of our result is 3. 
Result so far: 80442.29563
Deduct 1512 from 1760 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Moving on to step 14:
2480 divided by 504 is 4 with a remainder of 464.
Record the quotient 4 as the next digit in the result. 
Result so far: 80442.295634
If we subtract 2016 from 2480, we get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Going ahead to step 15:
504 can be fit into 4640 9 times, resulting in a remainder of 104.
Put 9 as the next digit of the answer. 
Result so far: 80442.2956349
The remainder is 104 after subtracting 4536 from 4640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 16:
The number 504 fits into 1040 2 times, leaving a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 80442.29563492
Deduct 1008 from 1040 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 80442.29563492 with a balance of 3.2e-08.
