81228646 ÷ 242 
Our goal is to divide 81228646 by 242.

Going ahead to step 1:
8 divided by 242 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 242

Advancing to step 2:
81 divided by 242 is 0 with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Bring next digit (2) of the dividend behind the 81 and repeat the process: 812 / 242

Moving on to step 3:
The number 242 fits into 812 3 times, leaving a remainder of 86.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 726 from 812 to get 86.
Take the next digit (2) from the dividend and append it to 86, then repeat: 862 / 242

Moving on to step 4:
862 divided by 242 is 3 with a remainder of 136.
Put 3 as the next digit of the answer. 
Result so far: 33.0
If we take 726 away from 862, we end up with 136.
Grab the next digit (8) from the dividend, add it to 136, then carry on: 1368 / 242

Moving on to step 5:
When dividing 1368 by 242, we get 5 with a remainder of 158.
Write down 5 as next digit of the result. 
Result so far: 335.0
Subtract 1210 from 1368 to get 158.
Take the next digit (6) from the dividend and append it to 158, then repeat: 1586 / 242

Let's proceed to step 6:
242 goes into 1586 6 times with a remainder of 134.
Put 6 as the next digit of the answer. 
Result so far: 3356.0
Deduct 1452 from 1586 and we're left with 134.
Grab the next digit (4) from the dividend, add it to 134, then carry on: 1344 / 242

Advancing to step 7:
1344 divided by 242 is 5 with a remainder of 134.
Use 5 as the next digit of our solution. 
Result so far: 33565.0
The remainder is 134 after subtracting 1210 from 1344.
Append the next digit (6) from the dividend to 134 and continue with: 1346 / 242

Step 8:
242 can be fit into 1346 5 times, resulting in a remainder of 136.
Write down 5 as next digit of the result. 
Result so far: 335655.0
The remainder is 136 after subtracting 1210 from 1346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 9:
If we divide 1360 by 242, we get 5 and a remainder of 150.
Put 5 as the next digit of the answer. 
Result so far: 335655.5
If we subtract 1210 from 1360, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 10:
242 can be fit into 1500 6 times, resulting in a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 335655.56
If we take 1452 away from 1500, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 11:
242 can be fit into 480 1 times, resulting in a remainder of 238.
The next digit of our result is 1. 
Result so far: 335655.561
If we take 242 away from 480, we end up with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Going ahead to step 12:
242 can be fit into 2380 9 times, resulting in a remainder of 202.
Put 9 as the next digit of the answer. 
Result so far: 335655.5619
Subtracting 2178 from 2380 leaves us with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Going ahead to step 13:
If we divide 2020 by 242, we get 8 and a remainder of 84.
Record the quotient 8 as the next digit in the result. 
Result so far: 335655.56198
If we subtract 1936 from 2020, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 14:
840 divided by 242 is 3 with a remainder of 114.
The next digit of our result is 3. 
Result so far: 335655.561983
The remainder is 114 after subtracting 726 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

On to step 15:
The number 242 fits into 1140 4 times, leaving a remainder of 172.
The next digit of our result is 4. 
Result so far: 335655.5619834
If we subtract 968 from 1140, we get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Let's proceed to step 16:
If we divide 1720 by 242, we get 7 and a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 335655.56198347
Subtract 1694 from 1720 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Our division results in 335655.56198347 with a remaining 2.6e-08.
