86205210 ÷ 342 
Let's see how many times 342 fits into 86205210.

Moving on to step 1:
8 divided by 342 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 342

Let's proceed to step 2:
The number 342 fits into 86 0 times, leaving a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Fetch the next digit (2) from the dividend, attach it to 86 and continue: 862 / 342

Let's proceed to step 3:
If we divide 862 by 342, we get 2 and a remainder of 178.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 684 from 862 and we're left with 178.
Append the next digit (0) from the dividend to 178 and continue with: 1780 / 342

Going ahead to step 4:
342 goes into 1780 5 times with a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 25.0
If we subtract 1710 from 1780, we get 70.
Grab the next digit (5) from the dividend, add it to 70, then carry on: 705 / 342

Advancing to step 5:
342 goes into 705 2 times with a remainder of 21.
Record the quotient 2 as the next digit in the result. 
Result so far: 252.0
Subtracting 684 from 705 leaves us with 21.
Append the next digit (2) from the dividend to 21 and continue with: 212 / 342

Advancing to step 6:
342 can be fit into 212 0 times, resulting in a remainder of 212.
Write down 0 as next digit of the result. 
Result so far: 2520.0
If we subtract 0 from 212, we get 212.
Fetch the next digit (1) from the dividend, attach it to 212 and continue: 2121 / 342

Step 7:
342 can be fit into 2121 6 times, resulting in a remainder of 69.
Put 6 as the next digit of the answer. 
Result so far: 25206.0
Deduct 2052 from 2121 and we're left with 69.
Bring next digit (0) of the dividend behind the 69 and repeat the process: 690 / 342

Going ahead to step 8:
The number 342 fits into 690 2 times, leaving a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 252062.0
Deduct 684 from 690 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
The number 342 fits into 60 0 times, leaving a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 252062.0
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 10:
342 can be fit into 600 1 times, resulting in a remainder of 258.
Use 1 as the next digit of our solution. 
Result so far: 252062.01
Subtracting 342 from 600 leaves us with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Advancing to step 11:
342 can be fit into 2580 7 times, resulting in a remainder of 186.
Write down 7 as next digit of the result. 
Result so far: 252062.017
Deduct 2394 from 2580 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 12:
342 can be fit into 1860 5 times, resulting in a remainder of 150.
Record the quotient 5 as the next digit in the result. 
Result so far: 252062.0175
The remainder is 150 after subtracting 1710 from 1860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 13:
The number 342 fits into 1500 4 times, leaving a remainder of 132.
Use 4 as the next digit of our solution. 
Result so far: 252062.01754
Deduct 1368 from 1500 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Moving on to step 14:
342 can be fit into 1320 3 times, resulting in a remainder of 294.
The next digit of our result is 3. 
Result so far: 252062.017543
If we take 1026 away from 1320, we end up with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Moving on to step 15:
If we divide 2940 by 342, we get 8 and a remainder of 204.
Record the quotient 8 as the next digit in the result. 
Result so far: 252062.0175438
If we subtract 2736 from 2940, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Advancing to step 16:
342 can be fit into 2040 5 times, resulting in a remainder of 330.
Record the quotient 5 as the next digit in the result. 
Result so far: 252062.01754385
Deduct 1710 from 2040 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

After the division, we end up with 252062.01754385 and a remainder of 3.3e-07.
