We divide 186686 by 7
Our goal is to divide 186686 by 7.

Let's proceed to step 1:
If we divide 1 by 7, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 7

Going ahead to step 2:
If we divide 18 by 7, we get 2 and a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 14 from 18, we get 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 7

Advancing to step 3:
The number 7 fits into 46 6 times, leaving a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
Deduct 42 from 46 and we're left with 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 7

On to step 4:
46 divided by 7 is 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 266.0
The remainder is 4 after subtracting 42 from 46.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 7

Advancing to step 5:
7 can be fit into 48 6 times, resulting in a remainder of 6.
The next digit of our result is 6. 
Result so far: 2666.0
Subtracting 42 from 48 leaves us with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 7

Advancing to step 6:
7 can be fit into 66 9 times, resulting in a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 26669.0
If we subtract 63 from 66, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
When dividing 30 by 7, we get 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 26669.4
If we take 28 away from 30, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
7 goes into 20 2 times with a remainder of 6.
The next digit of our result is 2. 
Result so far: 26669.42
If we subtract 14 from 20, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
When dividing 60 by 7, we get 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 26669.428
If we subtract 56 from 60, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
When dividing 40 by 7, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 26669.4285
The remainder is 5 after subtracting 35 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 11:
7 goes into 50 7 times with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 26669.42857
Subtract 49 from 50 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 12:
10 divided by 7 is 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 26669.428571
If we take 7 away from 10, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 13:
7 can be fit into 30 4 times, resulting in a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 26669.4285714
If we take 28 away from 30, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 14:
The number 7 fits into 20 2 times, leaving a remainder of 6.
The next digit of our result is 2. 
Result so far: 26669.42857142
Deduct 14 from 20 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.

In conclusion, the division gives 26669.42857142 with a balance of 6e-09.
