81761968 ÷ 342 
We want to divide 81761968 by 342.

Step 1:
When dividing 8 by 342, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 342

On to step 2:
When dividing 81 by 342, we get 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Include the next digit (7) from the dividend after 81, then repeat: 817 / 342

Step 3:
If we divide 817 by 342, we get 2 and a remainder of 133.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 684 away from 817, we end up with 133.
Fetch the next digit (6) from the dividend, attach it to 133 and continue: 1336 / 342

Step 4:
The number 342 fits into 1336 3 times, leaving a remainder of 310.
Use 3 as the next digit of our solution. 
Result so far: 23.0
The remainder is 310 after subtracting 1026 from 1336.
Include the next digit (1) from the dividend after 310, then repeat: 3101 / 342

On to step 5:
342 goes into 3101 9 times with a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 239.0
If we take 3078 away from 3101, we end up with 23.
Take the next digit (9) from the dividend and append it to 23, then repeat: 239 / 342

On to step 6:
239 divided by 342 is 0 with a remainder of 239.
Record the quotient 0 as the next digit in the result. 
Result so far: 2390.0
The remainder is 239 after subtracting 0 from 239.
Take the next digit (6) from the dividend and append it to 239, then repeat: 2396 / 342

Advancing to step 7:
342 goes into 2396 7 times with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 23907.0
If we take 2394 away from 2396, we end up with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 342

Step 8:
342 can be fit into 28 0 times, resulting in a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 239070.0
Subtract 0 from 28 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 9:
342 can be fit into 280 0 times, resulting in a remainder of 280.
The number 0 becomes the next digit in our result. 
Result so far: 239070.0
Deduct 0 from 280 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 10:
When dividing 2800 by 342, we get 8 with a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 239070.08
Subtract 2736 from 2800 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 11:
If we divide 640 by 342, we get 1 and a remainder of 298.
The number 1 becomes the next digit in our result. 
Result so far: 239070.081
Deduct 342 from 640 and we're left with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Advancing to step 12:
If we divide 2980 by 342, we get 8 and a remainder of 244.
Write down 8 as next digit of the result. 
Result so far: 239070.0818
If we subtract 2736 from 2980, we get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Step 13:
If we divide 2440 by 342, we get 7 and a remainder of 46.
Write down 7 as next digit of the result. 
Result so far: 239070.08187
If we take 2394 away from 2440, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 14:
460 divided by 342 is 1 with a remainder of 118.
The next digit of our result is 1. 
Result so far: 239070.081871
Deduct 342 from 460 and we're left with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Let's proceed to step 15:
If we divide 1180 by 342, we get 3 and a remainder of 154.
Use 3 as the next digit of our solution. 
Result so far: 239070.0818713
If we subtract 1026 from 1180, we get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Step 16:
If we divide 1540 by 342, we get 4 and a remainder of 172.
Put 4 as the next digit of the answer. 
Result so far: 239070.08187134
If we subtract 1368 from 1540, 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.

The final result is 239070.08187134 with a remainder of 1.72e-07.
