Let's divide 45342464 by 821
We want to figure out the number of times 45342464 can be divided by 821.

Advancing to step 1:
4 divided by 821 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 821

Advancing to step 2:
45 divided by 821 is 0 with a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Grab the next digit (3) from the dividend, add it to 45, then carry on: 453 / 821

Advancing to step 3:
If we divide 453 by 821, we get 0 and a remainder of 453.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 453, we get 453.
Append the next digit (4) from the dividend to 453 and continue with: 4534 / 821

Step 4:
4534 divided by 821 is 5 with a remainder of 429.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 4105 from 4534 and we're left with 429.
Take the next digit (2) from the dividend and append it to 429, then repeat: 4292 / 821

Let's proceed to step 5:
When dividing 4292 by 821, we get 5 with a remainder of 187.
Use 5 as the next digit of our solution. 
Result so far: 55.0
If we subtract 4105 from 4292, we get 187.
Bring next digit (4) of the dividend behind the 187 and repeat the process: 1874 / 821

Going ahead to step 6:
If we divide 1874 by 821, we get 2 and a remainder of 232.
Use 2 as the next digit of our solution. 
Result so far: 552.0
The remainder is 232 after subtracting 1642 from 1874.
Grab the next digit (6) from the dividend, add it to 232, then carry on: 2326 / 821

Moving on to step 7:
821 can be fit into 2326 2 times, resulting in a remainder of 684.
The number 2 becomes the next digit in our result. 
Result so far: 5522.0
Deduct 1642 from 2326 and we're left with 684.
Fetch the next digit (4) from the dividend, attach it to 684 and continue: 6844 / 821

On to step 8:
821 can be fit into 6844 8 times, resulting in a remainder of 276.
Use 8 as the next digit of our solution. 
Result so far: 55228.0
Subtracting 6568 from 6844 leaves us with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Moving on to step 9:
2760 divided by 821 is 3 with a remainder of 297.
Use 3 as the next digit of our solution. 
Result so far: 55228.3
Deduct 2463 from 2760 and we're left with 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

On to step 10:
821 can be fit into 2970 3 times, resulting in a remainder of 507.
The number 3 becomes the next digit in our result. 
Result so far: 55228.33
The remainder is 507 after subtracting 2463 from 2970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

After the division, we end up with 55228.33 and a remainder of 0.507.
