86070608 ÷ 342 
Our goal is to divide 86070608 by 342.

Advancing to step 1:
The number 342 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 342

Let's proceed to step 2:
342 can be fit into 86 0 times, resulting in a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Include the next digit (0) from the dividend after 86, then repeat: 860 / 342

Moving on to step 3:
860 divided by 342 is 2 with a remainder of 176.
The next digit of our result is 2. 
Result so far: 2.0
If we take 684 away from 860, we end up with 176.
Include the next digit (7) from the dividend after 176, then repeat: 1767 / 342

Moving on to step 4:
When dividing 1767 by 342, we get 5 with a remainder of 57.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
If we take 1710 away from 1767, we end up with 57.
Include the next digit (0) from the dividend after 57, then repeat: 570 / 342

Advancing to step 5:
When dividing 570 by 342, we get 1 with a remainder of 228.
Write down 1 as next digit of the result. 
Result so far: 251.0
Deduct 342 from 570 and we're left with 228.
Include the next digit (6) from the dividend after 228, then repeat: 2286 / 342

Going ahead to step 6:
When dividing 2286 by 342, we get 6 with a remainder of 234.
The next digit of our result is 6. 
Result so far: 2516.0
If we subtract 2052 from 2286, we get 234.
Bring next digit (0) of the dividend behind the 234 and repeat the process: 2340 / 342

Advancing to step 7:
The number 342 fits into 2340 6 times, leaving a remainder of 288.
Use 6 as the next digit of our solution. 
Result so far: 25166.0
If we take 2052 away from 2340, we end up with 288.
Take the next digit (8) from the dividend and append it to 288, then repeat: 2888 / 342

Step 8:
If we divide 2888 by 342, we get 8 and a remainder of 152.
Write down 8 as next digit of the result. 
Result so far: 251668.0
If we take 2736 away from 2888, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 9:
342 goes into 1520 4 times with a remainder of 152.
Write down 4 as next digit of the result. 
Result so far: 251668.4
If we subtract 1368 from 1520, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 10:
342 goes into 1520 4 times with a remainder of 152.
Record the quotient 4 as the next digit in the result. 
Result so far: 251668.44
If we subtract 1368 from 1520, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

The quotient of the division is 251668.44, and the remainder is 0.152.
