Let's divide 81721587 by 497
We want to divide 81721587 by 497.

Moving on to step 1:
497 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 497

On to step 2:
If we divide 81 by 497, we get 0 and a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Take the next digit (7) from the dividend and append it to 81, then repeat: 817 / 497

Let's proceed to step 3:
The number 497 fits into 817 1 times, leaving a remainder of 320.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 497 from 817 to get 320.
Grab the next digit (2) from the dividend, add it to 320, then carry on: 3202 / 497

Advancing to step 4:
When dividing 3202 by 497, we get 6 with a remainder of 220.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we take 2982 away from 3202, we end up with 220.
Include the next digit (1) from the dividend after 220, then repeat: 2201 / 497

Moving on to step 5:
If we divide 2201 by 497, we get 4 and a remainder of 213.
Put 4 as the next digit of the answer. 
Result so far: 164.0
If we subtract 1988 from 2201, we get 213.
Append the next digit (5) from the dividend to 213 and continue with: 2135 / 497

Let's proceed to step 6:
2135 divided by 497 is 4 with a remainder of 147.
Put 4 as the next digit of the answer. 
Result so far: 1644.0
The remainder is 147 after subtracting 1988 from 2135.
Append the next digit (8) from the dividend to 147 and continue with: 1478 / 497

Advancing to step 7:
497 goes into 1478 2 times with a remainder of 484.
Use 2 as the next digit of our solution. 
Result so far: 16442.0
Subtracting 994 from 1478 leaves us with 484.
Bring next digit (7) of the dividend behind the 484 and repeat the process: 4847 / 497

On to step 8:
4847 divided by 497 is 9 with a remainder of 374.
Write down 9 as next digit of the result. 
Result so far: 164429.0
If we subtract 4473 from 4847, we get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Going ahead to step 9:
The number 497 fits into 3740 7 times, leaving a remainder of 261.
Record the quotient 7 as the next digit in the result. 
Result so far: 164429.7
If we take 3479 away from 3740, we end up with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

On to step 10:
497 goes into 2610 5 times with a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 164429.75
Subtracting 2485 from 2610 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 11:
497 goes into 1250 2 times with a remainder of 256.
Use 2 as the next digit of our solution. 
Result so far: 164429.752
If we subtract 994 from 1250, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 12:
497 goes into 2560 5 times with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 164429.7525
Subtracting 2485 from 2560 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 13:
497 can be fit into 750 1 times, resulting in a remainder of 253.
The number 1 becomes the next digit in our result. 
Result so far: 164429.75251
Subtract 497 from 750 to get 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Advancing to step 14:
497 can be fit into 2530 5 times, resulting in a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 164429.752515
The remainder is 45 after subtracting 2485 from 2530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 15:
497 goes into 450 0 times with a remainder of 450.
Use 0 as the next digit of our solution. 
Result so far: 164429.752515
If we subtract 0 from 450, we get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 16:
If we divide 4500 by 497, we get 9 and a remainder of 27.
The next digit of our result is 9. 
Result so far: 164429.75251509
If we subtract 4473 from 4500, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The final result is 164429.75251509 with a remainder of 2.7e-08.
