45467421 ÷ 504 
Our goal is to divide 45467421 by 504.

Moving on to step 1:
If we divide 4 by 504, we get 0 and 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 (5) from the dividend and append it to 4, then repeat: 45 / 504

Going ahead to step 2:
If we divide 45 by 504, we get 0 and a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Take the next digit (4) from the dividend and append it to 45, then repeat: 454 / 504

On to step 3:
When dividing 454 by 504, we get 0 with a remainder of 454.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 454 leaves us with 454.
Include the next digit (6) from the dividend after 454, then repeat: 4546 / 504

Moving on to step 4:
If we divide 4546 by 504, we get 9 and a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 4536 from 4546 to get 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 504

Let's proceed to step 5:
When dividing 107 by 504, we get 0 with a remainder of 107.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
If we take 0 away from 107, we end up with 107.
Append the next digit (4) from the dividend to 107 and continue with: 1074 / 504

Going ahead to step 6:
The number 504 fits into 1074 2 times, leaving a remainder of 66.
Record the quotient 2 as the next digit in the result. 
Result so far: 902.0
The remainder is 66 after subtracting 1008 from 1074.
Grab the next digit (2) from the dividend, add it to 66, then carry on: 662 / 504

Moving on to step 7:
504 goes into 662 1 times with a remainder of 158.
The next digit of our result is 1. 
Result so far: 9021.0
If we take 504 away from 662, we end up with 158.
Take the next digit (1) from the dividend and append it to 158, then repeat: 1581 / 504

Step 8:
504 can be fit into 1581 3 times, resulting in a remainder of 69.
The next digit of our result is 3. 
Result so far: 90213.0
If we take 1512 away from 1581, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 9:
504 goes into 690 1 times with a remainder of 186.
Use 1 as the next digit of our solution. 
Result so far: 90213.1
Deduct 504 from 690 and we're left with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Let's proceed to step 10:
If we divide 1860 by 504, we get 3 and a remainder of 348.
Write down 3 as next digit of the result. 
Result so far: 90213.13
If we take 1512 away from 1860, we end up with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Advancing to step 11:
504 goes into 3480 6 times with a remainder of 456.
The next digit of our result is 6. 
Result so far: 90213.136
Deduct 3024 from 3480 and we're left with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Advancing to step 12:
504 goes into 4560 9 times with a remainder of 24.
Put 9 as the next digit of the answer. 
Result so far: 90213.1369
The remainder is 24 after subtracting 4536 from 4560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 13:
When dividing 240 by 504, we get 0 with a remainder of 240.
Write down 0 as next digit of the result. 
Result so far: 90213.1369
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 14:
If we divide 2400 by 504, we get 4 and a remainder of 384.
The next digit of our result is 4. 
Result so far: 90213.136904
If we take 2016 away from 2400, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 15:
If we divide 3840 by 504, we get 7 and a remainder of 312.
The next digit of our result is 7. 
Result so far: 90213.1369047
Deduct 3528 from 3840 and we're left with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Let's proceed to step 16:
3120 divided by 504 is 6 with a remainder of 96.
Record the quotient 6 as the next digit in the result. 
Result so far: 90213.13690476
Deduct 3024 from 3120 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

The final result is 90213.13690476 with a remainder of 9.6e-08.
