43542679 divided by 504 
We want to figure out the number of times 43542679 can be divided by 504.

Advancing to step 1:
4 divided by 504 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 504

Advancing to step 2:
504 can be fit into 43 0 times, resulting in a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Append the next digit (5) from the dividend to 43 and continue with: 435 / 504

Step 3:
504 can be fit into 435 0 times, resulting in a remainder of 435.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 435, we get 435.
Grab the next digit (4) from the dividend, add it to 435, then carry on: 4354 / 504

Let's proceed to step 4:
4354 divided by 504 is 8 with a remainder of 322.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 4032 away from 4354, we end up with 322.
Take the next digit (2) from the dividend and append it to 322, then repeat: 3222 / 504

Step 5:
3222 divided by 504 is 6 with a remainder of 198.
The next digit of our result is 6. 
Result so far: 86.0
Subtract 3024 from 3222 to get 198.
Include the next digit (6) from the dividend after 198, then repeat: 1986 / 504

On to step 6:
The number 504 fits into 1986 3 times, leaving a remainder of 474.
The number 3 becomes the next digit in our result. 
Result so far: 863.0
If we take 1512 away from 1986, we end up with 474.
Fetch the next digit (7) from the dividend, attach it to 474 and continue: 4747 / 504

Moving on to step 7:
When dividing 4747 by 504, we get 9 with a remainder of 211.
The next digit of our result is 9. 
Result so far: 8639.0
If we take 4536 away from 4747, we end up with 211.
Append the next digit (9) from the dividend to 211 and continue with: 2119 / 504

Advancing to step 8:
2119 divided by 504 is 4 with a remainder of 103.
The number 4 becomes the next digit in our result. 
Result so far: 86394.0
The remainder is 103 after subtracting 2016 from 2119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Advancing to step 9:
504 goes into 1030 2 times with a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 86394.2
The remainder is 22 after subtracting 1008 from 1030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 10:
The number 504 fits into 220 0 times, leaving a remainder of 220.
Write down 0 as next digit of the result. 
Result so far: 86394.2
Subtract 0 from 220 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 11:
The number 504 fits into 2200 4 times, leaving a remainder of 184.
Write down 4 as next digit of the result. 
Result so far: 86394.204
Deduct 2016 from 2200 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 12:
When dividing 1840 by 504, we get 3 with a remainder of 328.
Use 3 as the next digit of our solution. 
Result so far: 86394.2043
If we take 1512 away from 1840, we end up with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

On to step 13:
3280 divided by 504 is 6 with a remainder of 256.
The next digit of our result is 6. 
Result so far: 86394.20436
Deduct 3024 from 3280 and we're left with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Moving on to step 14:
504 can be fit into 2560 5 times, resulting in a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 86394.204365
If we subtract 2520 from 2560, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 15:
When dividing 400 by 504, we get 0 with a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 86394.204365
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 16:
When dividing 4000 by 504, we get 7 with a remainder of 472.
Record the quotient 7 as the next digit in the result. 
Result so far: 86394.20436507
Subtract 3528 from 4000 to get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

The quotient of the division is 86394.20436507, and the remainder is 4.72e-07.
