Let's divide 84128464 by 504
We want to figure out the number of times 84128464 can be divided by 504.

Going ahead to step 1:
The number 504 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 504

Step 2:
504 can be fit into 84 0 times, resulting in a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Include the next digit (1) from the dividend after 84, then repeat: 841 / 504

Advancing to step 3:
504 can be fit into 841 1 times, resulting in a remainder of 337.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 504 from 841 leaves us with 337.
Take the next digit (2) from the dividend and append it to 337, then repeat: 3372 / 504

Step 4:
When dividing 3372 by 504, we get 6 with a remainder of 348.
Use 6 as the next digit of our solution. 
Result so far: 16.0
The remainder is 348 after subtracting 3024 from 3372.
Take the next digit (8) from the dividend and append it to 348, then repeat: 3488 / 504

Advancing to step 5:
3488 divided by 504 is 6 with a remainder of 464.
The next digit of our result is 6. 
Result so far: 166.0
If we subtract 3024 from 3488, we get 464.
Bring next digit (4) of the dividend behind the 464 and repeat the process: 4644 / 504

Let's proceed to step 6:
If we divide 4644 by 504, we get 9 and a remainder of 108.
Record the quotient 9 as the next digit in the result. 
Result so far: 1669.0
The remainder is 108 after subtracting 4536 from 4644.
Grab the next digit (6) from the dividend, add it to 108, then carry on: 1086 / 504

Moving on to step 7:
The number 504 fits into 1086 2 times, leaving a remainder of 78.
Record the quotient 2 as the next digit in the result. 
Result so far: 16692.0
The remainder is 78 after subtracting 1008 from 1086.
Fetch the next digit (4) from the dividend, attach it to 78 and continue: 784 / 504

Going ahead to step 8:
When dividing 784 by 504, we get 1 with a remainder of 280.
Put 1 as the next digit of the answer. 
Result so far: 166921.0
The remainder is 280 after subtracting 504 from 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 9:
When dividing 2800 by 504, we get 5 with a remainder of 280.
The next digit of our result is 5. 
Result so far: 166921.5
If we take 2520 away from 2800, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 10:
If we divide 2800 by 504, we get 5 and a remainder of 280.
Use 5 as the next digit of our solution. 
Result so far: 166921.55
If we subtract 2520 from 2800, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

The final result is 166921.55 with a remainder of 0.28.
