45721483 ÷ 817 
We want to divide 45721483 by 817.

Step 1:
817 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 817

Advancing to step 2:
817 can be fit into 45 0 times, resulting in a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Fetch the next digit (7) from the dividend, attach it to 45 and continue: 457 / 817

Moving on to step 3:
457 divided by 817 is 0 with a remainder of 457.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 457 to get 457.
Fetch the next digit (2) from the dividend, attach it to 457 and continue: 4572 / 817

Let's proceed to step 4:
817 goes into 4572 5 times with a remainder of 487.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 4085 from 4572, we get 487.
Take the next digit (1) from the dividend and append it to 487, then repeat: 4871 / 817

On to step 5:
4871 divided by 817 is 5 with a remainder of 786.
The next digit of our result is 5. 
Result so far: 55.0
Subtract 4085 from 4871 to get 786.
Include the next digit (4) from the dividend after 786, then repeat: 7864 / 817

Advancing to step 6:
7864 divided by 817 is 9 with a remainder of 511.
Use 9 as the next digit of our solution. 
Result so far: 559.0
Deduct 7353 from 7864 and we're left with 511.
Take the next digit (8) from the dividend and append it to 511, then repeat: 5118 / 817

Advancing to step 7:
When dividing 5118 by 817, we get 6 with a remainder of 216.
Use 6 as the next digit of our solution. 
Result so far: 5596.0
The remainder is 216 after subtracting 4902 from 5118.
Bring next digit (3) of the dividend behind the 216 and repeat the process: 2163 / 817

On to step 8:
817 can be fit into 2163 2 times, resulting in a remainder of 529.
Put 2 as the next digit of the answer. 
Result so far: 55962.0
Subtracting 1634 from 2163 leaves us with 529.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5290, and continue the process.

Moving on to step 9:
The number 817 fits into 5290 6 times, leaving a remainder of 388.
The number 6 becomes the next digit in our result. 
Result so far: 55962.6
The remainder is 388 after subtracting 4902 from 5290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Going ahead to step 10:
3880 divided by 817 is 4 with a remainder of 612.
Use 4 as the next digit of our solution. 
Result so far: 55962.64
Subtracting 3268 from 3880 leaves us with 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Advancing to step 11:
When dividing 6120 by 817, we get 7 with a remainder of 401.
Put 7 as the next digit of the answer. 
Result so far: 55962.647
Subtracting 5719 from 6120 leaves us with 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Moving on to step 12:
4010 divided by 817 is 4 with a remainder of 742.
Use 4 as the next digit of our solution. 
Result so far: 55962.6474
Subtract 3268 from 4010 to get 742.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7420, and continue the process.

Going ahead to step 13:
817 goes into 7420 9 times with a remainder of 67.
The next digit of our result is 9. 
Result so far: 55962.64749
If we take 7353 away from 7420, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 14:
If we divide 670 by 817, we get 0 and a remainder of 670.
Put 0 as the next digit of the answer. 
Result so far: 55962.64749
If we take 0 away from 670, we end up with 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Moving on to step 15:
When dividing 6700 by 817, we get 8 with a remainder of 164.
Put 8 as the next digit of the answer. 
Result so far: 55962.6474908
The remainder is 164 after subtracting 6536 from 6700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Going ahead to step 16:
1640 divided by 817 is 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 55962.64749082
Subtracting 1634 from 1640 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 55962.64749082 with a remainder of 6e-09.
