We divide 81987791 by 499
Our goal is to divide 81987791 by 499.

Going ahead to step 1:
When dividing 8 by 499, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 499

Advancing to step 2:
499 goes into 81 0 times with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Take the next digit (9) from the dividend and append it to 81, then repeat: 819 / 499

Going ahead to step 3:
819 divided by 499 is 1 with a remainder of 320.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 499 from 819 leaves us with 320.
Grab the next digit (8) from the dividend, add it to 320, then carry on: 3208 / 499

Going ahead to step 4:
499 goes into 3208 6 times with a remainder of 214.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we subtract 2994 from 3208, we get 214.
Bring next digit (7) of the dividend behind the 214 and repeat the process: 2147 / 499

Let's proceed to step 5:
When dividing 2147 by 499, we get 4 with a remainder of 151.
Put 4 as the next digit of the answer. 
Result so far: 164.0
If we take 1996 away from 2147, we end up with 151.
Bring next digit (7) of the dividend behind the 151 and repeat the process: 1517 / 499

Going ahead to step 6:
1517 divided by 499 is 3 with a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 1643.0
Subtract 1497 from 1517 to get 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 499

On to step 7:
If we divide 209 by 499, we get 0 and a remainder of 209.
The next digit of our result is 0. 
Result so far: 16430.0
Subtracting 0 from 209 leaves us with 209.
Include the next digit (1) from the dividend after 209, then repeat: 2091 / 499

On to step 8:
499 can be fit into 2091 4 times, resulting in a remainder of 95.
Write down 4 as next digit of the result. 
Result so far: 164304.0
Subtract 1996 from 2091 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Step 9:
The number 499 fits into 950 1 times, leaving a remainder of 451.
Put 1 as the next digit of the answer. 
Result so far: 164304.1
Subtracting 499 from 950 leaves us with 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Let's proceed to step 10:
4510 divided by 499 is 9 with a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 164304.19
If we take 4491 away from 4510, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 11:
The number 499 fits into 190 0 times, leaving a remainder of 190.
Record the quotient 0 as the next digit in the result. 
Result so far: 164304.19
The remainder is 190 after subtracting 0 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 12:
499 can be fit into 1900 3 times, resulting in a remainder of 403.
Write down 3 as next digit of the result. 
Result so far: 164304.1903
Subtract 1497 from 1900 to get 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

On to step 13:
The number 499 fits into 4030 8 times, leaving a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 164304.19038
Subtract 3992 from 4030 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 14:
499 goes into 380 0 times with a remainder of 380.
Record the quotient 0 as the next digit in the result. 
Result so far: 164304.19038
Subtract 0 from 380 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 15:
3800 divided by 499 is 7 with a remainder of 307.
Record the quotient 7 as the next digit in the result. 
Result so far: 164304.1903807
The remainder is 307 after subtracting 3493 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Going ahead to step 16:
When dividing 3070 by 499, we get 6 with a remainder of 76.
The next digit of our result is 6. 
Result so far: 164304.19038076
Subtract 2994 from 3070 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

After the division, we end up with 164304.19038076 and a remainder of 7.6e-08.
