81127644 ÷ 321 
Our goal is to divide 81127644 by 321.

Let's proceed to step 1:
When dividing 8 by 321, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 321

Going ahead to step 2:
321 can be fit into 81 0 times, resulting in a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Bring next digit (1) of the dividend behind the 81 and repeat the process: 811 / 321

Going ahead to step 3:
321 goes into 811 2 times with a remainder of 169.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 169 after subtracting 642 from 811.
Grab the next digit (2) from the dividend, add it to 169, then carry on: 1692 / 321

Moving on to step 4:
The number 321 fits into 1692 5 times, leaving a remainder of 87.
Write down 5 as next digit of the result. 
Result so far: 25.0
The remainder is 87 after subtracting 1605 from 1692.
Fetch the next digit (7) from the dividend, attach it to 87 and continue: 877 / 321

Advancing to step 5:
The number 321 fits into 877 2 times, leaving a remainder of 235.
Put 2 as the next digit of the answer. 
Result so far: 252.0
Subtract 642 from 877 to get 235.
Bring next digit (6) of the dividend behind the 235 and repeat the process: 2356 / 321

Moving on to step 6:
If we divide 2356 by 321, we get 7 and a remainder of 109.
Write down 7 as next digit of the result. 
Result so far: 2527.0
If we subtract 2247 from 2356, we get 109.
Grab the next digit (4) from the dividend, add it to 109, then carry on: 1094 / 321

On to step 7:
The number 321 fits into 1094 3 times, leaving a remainder of 131.
Use 3 as the next digit of our solution. 
Result so far: 25273.0
The remainder is 131 after subtracting 963 from 1094.
Fetch the next digit (4) from the dividend, attach it to 131 and continue: 1314 / 321

Moving on to step 8:
321 goes into 1314 4 times with a remainder of 30.
The next digit of our result is 4. 
Result so far: 252734.0
If we subtract 1284 from 1314, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
The number 321 fits into 300 0 times, leaving a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 252734.0
Deduct 0 from 300 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 10:
3000 divided by 321 is 9 with a remainder of 111.
The next digit of our result is 9. 
Result so far: 252734.09
Deduct 2889 from 3000 and we're left with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Advancing to step 11:
When dividing 1110 by 321, we get 3 with a remainder of 147.
Put 3 as the next digit of the answer. 
Result so far: 252734.093
Deduct 963 from 1110 and we're left with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Moving on to step 12:
If we divide 1470 by 321, we get 4 and a remainder of 186.
Put 4 as the next digit of the answer. 
Result so far: 252734.0934
Deduct 1284 from 1470 and we're left with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Let's proceed to step 13:
321 can be fit into 1860 5 times, resulting in a remainder of 255.
Record the quotient 5 as the next digit in the result. 
Result so far: 252734.09345
If we subtract 1605 from 1860, we get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

On to step 14:
If we divide 2550 by 321, we get 7 and a remainder of 303.
Put 7 as the next digit of the answer. 
Result so far: 252734.093457
If we take 2247 away from 2550, we end up with 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Let's proceed to step 15:
When dividing 3030 by 321, we get 9 with a remainder of 141.
Use 9 as the next digit of our solution. 
Result so far: 252734.0934579
If we subtract 2889 from 3030, we get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Advancing to step 16:
321 can be fit into 1410 4 times, resulting in a remainder of 126.
The number 4 becomes the next digit in our result. 
Result so far: 252734.09345794
The remainder is 126 after subtracting 1284 from 1410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

After the division, we end up with 252734.09345794 and a remainder of 1.26e-07.
