91143664 ÷ 504 
Let's see how many times 504 fits into 91143664.

Step 1:
504 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 504

Moving on to step 2:
If we divide 91 by 504, we get 0 and a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Grab the next digit (1) from the dividend, add it to 91, then carry on: 911 / 504

Step 3:
504 can be fit into 911 1 times, resulting in a remainder of 407.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 504 from 911, we get 407.
Append the next digit (4) from the dividend to 407 and continue with: 4074 / 504

Moving on to step 4:
The number 504 fits into 4074 8 times, leaving a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtracting 4032 from 4074 leaves us with 42.
Take the next digit (3) from the dividend and append it to 42, then repeat: 423 / 504

Advancing to step 5:
504 goes into 423 0 times with a remainder of 423.
The number 0 becomes the next digit in our result. 
Result so far: 180.0
If we take 0 away from 423, we end up with 423.
Include the next digit (6) from the dividend after 423, then repeat: 4236 / 504

Step 6:
4236 divided by 504 is 8 with a remainder of 204.
The next digit of our result is 8. 
Result so far: 1808.0
If we take 4032 away from 4236, we end up with 204.
Include the next digit (6) from the dividend after 204, then repeat: 2046 / 504

Step 7:
The number 504 fits into 2046 4 times, leaving a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 18084.0
The remainder is 30 after subtracting 2016 from 2046.
Grab the next digit (4) from the dividend, add it to 30, then carry on: 304 / 504

Step 8:
504 goes into 304 0 times with a remainder of 304.
The next digit of our result is 0. 
Result so far: 180840.0
The remainder is 304 after subtracting 0 from 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

On to step 9:
504 goes into 3040 6 times with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 180840.6
Deduct 3024 from 3040 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
The number 504 fits into 160 0 times, leaving a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 180840.6
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 11:
1600 divided by 504 is 3 with a remainder of 88.
The number 3 becomes the next digit in our result. 
Result so far: 180840.603
Subtracting 1512 from 1600 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 12:
504 goes into 880 1 times with a remainder of 376.
The next digit of our result is 1. 
Result so far: 180840.6031
Deduct 504 from 880 and we're left with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Let's proceed to step 13:
The number 504 fits into 3760 7 times, leaving a remainder of 232.
The next digit of our result is 7. 
Result so far: 180840.60317
If we take 3528 away from 3760, we end up with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Let's proceed to step 14:
504 can be fit into 2320 4 times, resulting in a remainder of 304.
The next digit of our result is 4. 
Result so far: 180840.603174
If we subtract 2016 from 2320, we get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Let's proceed to step 15:
If we divide 3040 by 504, we get 6 and a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 180840.6031746
Subtracting 3024 from 3040 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 16:
504 goes into 160 0 times with a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 180840.6031746
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final outcome is 180840.6031746, with a leftover of 1.6e-07.
