81726688 ÷ 671 
We want to divide 81726688 by 671.

On to step 1:
When dividing 8 by 671, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 671

Going ahead to step 2:
81 divided by 671 is 0 with a remainder of 81.
The number 0 becomes the next digit in our 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 / 671

On to step 3:
671 can be fit into 817 1 times, resulting in a remainder of 146.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 671 from 817 leaves us with 146.
Fetch the next digit (2) from the dividend, attach it to 146 and continue: 1462 / 671

Step 4:
If we divide 1462 by 671, we get 2 and a remainder of 120.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we take 1342 away from 1462, we end up with 120.
Grab the next digit (6) from the dividend, add it to 120, then carry on: 1206 / 671

On to step 5:
If we divide 1206 by 671, we get 1 and a remainder of 535.
Put 1 as the next digit of the answer. 
Result so far: 121.0
The remainder is 535 after subtracting 671 from 1206.
Append the next digit (6) from the dividend to 535 and continue with: 5356 / 671

Moving on to step 6:
When dividing 5356 by 671, we get 7 with a remainder of 659.
Put 7 as the next digit of the answer. 
Result so far: 1217.0
If we subtract 4697 from 5356, we get 659.
Take the next digit (8) from the dividend and append it to 659, then repeat: 6598 / 671

Advancing to step 7:
671 goes into 6598 9 times with a remainder of 559.
The number 9 becomes the next digit in our result. 
Result so far: 12179.0
Deduct 6039 from 6598 and we're left with 559.
Grab the next digit (8) from the dividend, add it to 559, then carry on: 5598 / 671

Moving on to step 8:
5598 divided by 671 is 8 with a remainder of 230.
Put 8 as the next digit of the answer. 
Result so far: 121798.0
Subtracting 5368 from 5598 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 9:
When dividing 2300 by 671, we get 3 with a remainder of 287.
Record the quotient 3 as the next digit in the result. 
Result so far: 121798.3
If we take 2013 away from 2300, we end up with 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Advancing to step 10:
671 can be fit into 2870 4 times, resulting in a remainder of 186.
Use 4 as the next digit of our solution. 
Result so far: 121798.34
Subtract 2684 from 2870 to get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

On to step 11:
671 can be fit into 1860 2 times, resulting in a remainder of 518.
Use 2 as the next digit of our solution. 
Result so far: 121798.342
Deduct 1342 from 1860 and we're left with 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Going ahead to step 12:
If we divide 5180 by 671, we get 7 and a remainder of 483.
Record the quotient 7 as the next digit in the result. 
Result so far: 121798.3427
Subtracting 4697 from 5180 leaves us with 483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

Let's proceed to step 13:
When dividing 4830 by 671, we get 7 with a remainder of 133.
The next digit of our result is 7. 
Result so far: 121798.34277
Deduct 4697 from 4830 and we're left with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

After the division, we end up with 121798.34277 and a remainder of 0.000133.
