226640 ÷ 81 
We want to divide 226640 by 81.

Step 1:
2 divided by 81 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 81

Going ahead to step 2:
The number 81 fits into 22 0 times, leaving a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 22 after subtracting 0 from 22.
Grab the next digit (6) from the dividend, add it to 22, then carry on: 226 / 81

Let's proceed to step 3:
If we divide 226 by 81, we get 2 and a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 162 away from 226, we end up with 64.
Grab the next digit (6) from the dividend, add it to 64, then carry on: 646 / 81

Advancing to step 4:
When dividing 646 by 81, we get 7 with a remainder of 79.
Write down 7 as next digit of the result. 
Result so far: 27.0
If we take 567 away from 646, we end up with 79.
Fetch the next digit (4) from the dividend, attach it to 79 and continue: 794 / 81

Step 5:
794 divided by 81 is 9 with a remainder of 65.
Use 9 as the next digit of our solution. 
Result so far: 279.0
Subtract 729 from 794 to get 65.
Take the next digit (0) from the dividend and append it to 65, then repeat: 650 / 81

On to step 6:
If we divide 650 by 81, we get 8 and a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 2798.0
If we take 648 away from 650, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
81 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 2798.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
When dividing 200 by 81, we get 2 with a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 2798.02
If we subtract 162 from 200, we 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.

Advancing to step 9:
380 divided by 81 is 4 with a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 2798.024
Subtracting 324 from 380 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 10:
81 can be fit into 560 6 times, resulting in a remainder of 74.
The next digit of our result is 6. 
Result so far: 2798.0246
If we take 486 away from 560, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 11:
740 divided by 81 is 9 with a remainder of 11.
The next digit of our result is 9. 
Result so far: 2798.02469
Subtracting 729 from 740 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 12:
When dividing 110 by 81, we get 1 with a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 2798.024691
If we take 81 away from 110, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 13:
290 divided by 81 is 3 with a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 2798.0246913
Deduct 243 from 290 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 14:
If we divide 470 by 81, we get 5 and a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 2798.02469135
If we subtract 405 from 470, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

After the division, we end up with 2798.02469135 and a remainder of 6.5e-08.
