81709176 ÷ 486 
We want to divide 81709176 by 486.

Step 1:
8 divided by 486 is 0 with 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 / 486

Going ahead to step 2:
486 goes into 81 0 times with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Take the next digit (7) from the dividend and append it to 81, then repeat: 817 / 486

On to step 3:
When dividing 817 by 486, we get 1 with a remainder of 331.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 486 from 817 to get 331.
Include the next digit (0) from the dividend after 331, then repeat: 3310 / 486

Step 4:
486 goes into 3310 6 times with a remainder of 394.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtracting 2916 from 3310 leaves us with 394.
Include the next digit (9) from the dividend after 394, then repeat: 3949 / 486

On to step 5:
The number 486 fits into 3949 8 times, leaving a remainder of 61.
Write down 8 as next digit of the result. 
Result so far: 168.0
Subtracting 3888 from 3949 leaves us with 61.
Fetch the next digit (1) from the dividend, attach it to 61 and continue: 611 / 486

Advancing to step 6:
The number 486 fits into 611 1 times, leaving a remainder of 125.
Put 1 as the next digit of the answer. 
Result so far: 1681.0
Deduct 486 from 611 and we're left with 125.
Append the next digit (7) from the dividend to 125 and continue with: 1257 / 486

On to step 7:
486 can be fit into 1257 2 times, resulting in a remainder of 285.
The number 2 becomes the next digit in our result. 
Result so far: 16812.0
Deduct 972 from 1257 and we're left with 285.
Bring next digit (6) of the dividend behind the 285 and repeat the process: 2856 / 486

Going ahead to step 8:
486 can be fit into 2856 5 times, resulting in a remainder of 426.
The next digit of our result is 5. 
Result so far: 168125.0
If we subtract 2430 from 2856, we get 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Going ahead to step 9:
The number 486 fits into 4260 8 times, leaving a remainder of 372.
The number 8 becomes the next digit in our result. 
Result so far: 168125.8
Subtracting 3888 from 4260 leaves us with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Moving on to step 10:
486 goes into 3720 7 times with a remainder of 318.
The next digit of our result is 7. 
Result so far: 168125.87
The remainder is 318 after subtracting 3402 from 3720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

On to step 11:
3180 divided by 486 is 6 with a remainder of 264.
The number 6 becomes the next digit in our result. 
Result so far: 168125.876
Subtract 2916 from 3180 to get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Let's proceed to step 12:
486 can be fit into 2640 5 times, resulting in a remainder of 210.
The number 5 becomes the next digit in our result. 
Result so far: 168125.8765
If we take 2430 away from 2640, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 13:
When dividing 2100 by 486, we get 4 with a remainder of 156.
Record the quotient 4 as the next digit in the result. 
Result so far: 168125.87654
If we subtract 1944 from 2100, we get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Moving on to step 14:
The number 486 fits into 1560 3 times, leaving a remainder of 102.
Put 3 as the next digit of the answer. 
Result so far: 168125.876543
If we subtract 1458 from 1560, we get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 15:
If we divide 1020 by 486, we get 2 and a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 168125.8765432
The remainder is 48 after subtracting 972 from 1020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 16:
486 goes into 480 0 times with a remainder of 480.
Record the quotient 0 as the next digit in the result. 
Result so far: 168125.8765432
The remainder is 480 after subtracting 0 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

The quotient of the division is 168125.8765432, and the remainder is 4.8e-07.
