If we divide 7 by 686, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 686

On to step 2:
686 goes into 77 0 times with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Fetch the next digit (0) from the dividend, attach it to 77 and continue: 770 / 686

Going ahead to step 3:
If we divide 770 by 686, we get 1 and a remainder of 84.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 686 from 770 and we're left with 84.
Fetch the next digit (8) from the dividend, attach it to 84 and continue: 848 / 686

Let's proceed to step 4:
When dividing 848 by 686, we get 1 with a remainder of 162.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 686 from 848 to get 162.
Bring next digit (5) of the dividend behind the 162 and repeat the process: 1625 / 686

Advancing to step 5:
The number 686 fits into 1625 2 times, leaving a remainder of 253.
Use 2 as the next digit of our solution. 
Result so far: 112.0
Deduct 1372 from 1625 and we're left with 253.
Bring next digit (1) of the dividend behind the 253 and repeat the process: 2531 / 686

On to step 6:
When dividing 2531 by 686, we get 3 with a remainder of 473.
Put 3 as the next digit of the answer. 
Result so far: 1123.0
If we subtract 2058 from 2531, we get 473.
Bring next digit (2) of the dividend behind the 473 and repeat the process: 4732 / 686

Going ahead to step 7:
If we divide 4732 by 686, we get 6 and a remainder of 616.
Record the quotient 6 as the next digit in the result. 
Result so far: 11236.0
Deduct 4116 from 4732 and we're left with 616.
Append the next digit (2) from the dividend to 616 and continue with: 6162 / 686

On to step 8:
686 goes into 6162 8 times with a remainder of 674.
Put 8 as the next digit of the answer. 
Result so far: 112368.0
If we subtract 5488 from 6162, we get 674.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6740, and continue the process.

Let's proceed to step 9:
When dividing 6740 by 686, we get 9 with a remainder of 566.
Record the quotient 9 as the next digit in the result. 
Result so far: 112368.9
The remainder is 566 after subtracting 6174 from 6740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Step 10:
When dividing 5660 by 686, we get 8 with a remainder of 172.
Write down 8 as next digit of the result. 
Result so far: 112368.98
Subtracting 5488 from 5660 leaves us with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

On to step 11:
1720 divided by 686 is 2 with a remainder of 348.
Record the quotient 2 as the next digit in the result. 
Result so far: 112368.982
If we subtract 1372 from 1720, we get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Advancing to step 12:
3480 divided by 686 is 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 112368.9825
If we subtract 3430 from 3480, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 13:
The number 686 fits into 500 0 times, leaving a remainder of 500.
The next digit of our result is 0. 
Result so far: 112368.9825
The remainder is 500 after subtracting 0 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 14:
When dividing 5000 by 686, we get 7 with a remainder of 198.
The number 7 becomes the next digit in our result. 
Result so far: 112368.982507
Subtracting 4802 from 5000 leaves us with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Let's proceed to step 15:
When dividing 1980 by 686, we get 2 with a remainder of 608.
Write down 2 as next digit of the result. 
Result so far: 112368.9825072
If we subtract 1372 from 1980, we get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

On to step 16:
If we divide 6080 by 686, we get 8 and a remainder of 592.
Record the quotient 8 as the next digit in the result. 
Result so far: 112368.98250728
The remainder is 592 after subtracting 5488 from 6080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

The final outcome is 112368.98250728, with a leftover of 5.92e-07.
