168686 ÷ 87 
We're looking to find how many times 87 goes into 168686.

On to step 1:
1 divided by 87 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 87

Advancing to step 2:
87 can be fit into 16 0 times, resulting in a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Include the next digit (8) from the dividend after 16, then repeat: 168 / 87

Moving on to step 3:
If we divide 168 by 87, we get 1 and a remainder of 81.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 81 after subtracting 87 from 168.
Bring next digit (6) of the dividend behind the 81 and repeat the process: 816 / 87

Moving on to step 4:
If we divide 816 by 87, we get 9 and a remainder of 33.
The next digit of our result is 9. 
Result so far: 19.0
If we take 783 away from 816, we end up with 33.
Bring next digit (8) of the dividend behind the 33 and repeat the process: 338 / 87

Moving on to step 5:
87 can be fit into 338 3 times, resulting in a remainder of 77.
Use 3 as the next digit of our solution. 
Result so far: 193.0
Subtract 261 from 338 to get 77.
Bring next digit (6) of the dividend behind the 77 and repeat the process: 776 / 87

Let's proceed to step 6:
The number 87 fits into 776 8 times, leaving a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 1938.0
Subtract 696 from 776 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 7:
When dividing 800 by 87, we get 9 with a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 1938.9
Subtracting 783 from 800 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 8:
170 divided by 87 is 1 with a remainder of 83.
Write down 1 as next digit of the result. 
Result so far: 1938.91
Subtracting 87 from 170 leaves us with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Going ahead to step 9:
87 goes into 830 9 times with a remainder of 47.
The next digit of our result is 9. 
Result so far: 1938.919
If we take 783 away from 830, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 10:
When dividing 470 by 87, we get 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 1938.9195
Subtracting 435 from 470 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 11:
87 can be fit into 350 4 times, resulting in a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 1938.91954
If we subtract 348 from 350, 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.

Going ahead to step 12:
87 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 1938.91954
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 13:
The number 87 fits into 200 2 times, leaving a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 1938.9195402
If we take 174 away from 200, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 14:
260 divided by 87 is 2 with a remainder of 86.
The next digit of our result is 2. 
Result so far: 1938.91954022
If we take 174 away from 260, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

After the division, we end up with 1938.91954022 and a remainder of 8.6e-08.
