53216021 ÷ 824 
Let's see how many times 824 fits into 53216021.

Going ahead to step 1:
When dividing 5 by 824, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 824

Moving on to step 2:
824 goes into 53 0 times with a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Include the next digit (2) from the dividend after 53, then repeat: 532 / 824

Moving on to step 3:
532 divided by 824 is 0 with a remainder of 532.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 532, we get 532.
Append the next digit (1) from the dividend to 532 and continue with: 5321 / 824

Step 4:
824 goes into 5321 6 times with a remainder of 377.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 4944 from 5321 to get 377.
Bring next digit (6) of the dividend behind the 377 and repeat the process: 3776 / 824

Advancing to step 5:
824 can be fit into 3776 4 times, resulting in a remainder of 480.
Write down 4 as next digit of the result. 
Result so far: 64.0
If we subtract 3296 from 3776, we get 480.
Append the next digit (0) from the dividend to 480 and continue with: 4800 / 824

Step 6:
The number 824 fits into 4800 5 times, leaving a remainder of 680.
Record the quotient 5 as the next digit in the result. 
Result so far: 645.0
Deduct 4120 from 4800 and we're left with 680.
Grab the next digit (2) from the dividend, add it to 680, then carry on: 6802 / 824

Going ahead to step 7:
If we divide 6802 by 824, we get 8 and a remainder of 210.
The number 8 becomes the next digit in our result. 
Result so far: 6458.0
The remainder is 210 after subtracting 6592 from 6802.
Include the next digit (1) from the dividend after 210, then repeat: 2101 / 824

Moving on to step 8:
824 can be fit into 2101 2 times, resulting in a remainder of 453.
The next digit of our result is 2. 
Result so far: 64582.0
Deduct 1648 from 2101 and we're left with 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

Going ahead to step 9:
The number 824 fits into 4530 5 times, leaving a remainder of 410.
Write down 5 as next digit of the result. 
Result so far: 64582.5
Subtract 4120 from 4530 to get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Going ahead to step 10:
4100 divided by 824 is 4 with a remainder of 804.
Write down 4 as next digit of the result. 
Result so far: 64582.54
Subtracting 3296 from 4100 leaves us with 804.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8040, and continue the process.

Step 11:
The number 824 fits into 8040 9 times, leaving a remainder of 624.
Write down 9 as next digit of the result. 
Result so far: 64582.549
The remainder is 624 after subtracting 7416 from 8040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Moving on to step 12:
The number 824 fits into 6240 7 times, leaving a remainder of 472.
Write down 7 as next digit of the result. 
Result so far: 64582.5497
If we subtract 5768 from 6240, we 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.

Advancing to step 13:
If we divide 4720 by 824, we get 5 and a remainder of 600.
The number 5 becomes the next digit in our result. 
Result so far: 64582.54975
The remainder is 600 after subtracting 4120 from 4720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 14:
6000 divided by 824 is 7 with a remainder of 232.
Record the quotient 7 as the next digit in the result. 
Result so far: 64582.549757
If we take 5768 away from 6000, 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.

On to step 15:
824 can be fit into 2320 2 times, resulting in a remainder of 672.
The next digit of our result is 2. 
Result so far: 64582.5497572
Subtract 1648 from 2320 to get 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Step 16:
824 can be fit into 6720 8 times, resulting in a remainder of 128.
Put 8 as the next digit of the answer. 
Result so far: 64582.54975728
If we subtract 6592 from 6720, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The quotient of the division is 64582.54975728, and the remainder is 1.28e-07.
