342779 ÷ 86 
Let's see how many times 86 fits into 342779.

Step 1:
When dividing 3 by 86, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 86

Let's proceed to step 2:
86 goes into 34 0 times with a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Fetch the next digit (2) from the dividend, attach it to 34 and continue: 342 / 86

Moving on to step 3:
86 can be fit into 342 3 times, resulting in a remainder of 84.
The next digit of our result is 3. 
Result so far: 3.0
If we take 258 away from 342, we end up with 84.
Grab the next digit (7) from the dividend, add it to 84, then carry on: 847 / 86

Step 4:
86 goes into 847 9 times with a remainder of 73.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
If we take 774 away from 847, we end up with 73.
Fetch the next digit (7) from the dividend, attach it to 73 and continue: 737 / 86

Advancing to step 5:
86 can be fit into 737 8 times, resulting in a remainder of 49.
Put 8 as the next digit of the answer. 
Result so far: 398.0
If we subtract 688 from 737, we get 49.
Bring next digit (9) of the dividend behind the 49 and repeat the process: 499 / 86

Advancing to step 6:
When dividing 499 by 86, we get 5 with a remainder of 69.
Use 5 as the next digit of our solution. 
Result so far: 3985.0
If we subtract 430 from 499, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 7:
86 can be fit into 690 8 times, resulting in a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 3985.8
If we subtract 688 from 690, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
When dividing 20 by 86, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 3985.8
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
200 divided by 86 is 2 with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 3985.802
Deduct 172 from 200 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
If we divide 280 by 86, we get 3 and a remainder of 22.
The next digit of our result is 3. 
Result so far: 3985.8023
If we subtract 258 from 280, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 11:
When dividing 220 by 86, we get 2 with a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 3985.80232
The remainder is 48 after subtracting 172 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 12:
86 can be fit into 480 5 times, resulting in a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 3985.802325
Deduct 430 from 480 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 13:
When dividing 500 by 86, we get 5 with a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 3985.8023255
The remainder is 70 after subtracting 430 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final result is 3985.8023255 with a remainder of 7e-07.
