We look at the division of 687193 by 12 
Let's see how many times 12 fits into 687193.

Moving on to step 1:
When dividing 6 by 12, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 12

On to step 2:
If we divide 68 by 12, we get 5 and a remainder of 8.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 8 after subtracting 60 from 68.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 12

Going ahead to step 3:
87 divided by 12 is 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
If we subtract 84 from 87, we get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 12

Going ahead to step 4:
31 divided by 12 is 2 with a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 572.0
Subtracting 24 from 31 leaves us with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 12

On to step 5:
When dividing 79 by 12, we get 6 with a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 5726.0
Deduct 72 from 79 and we're left with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 12

Advancing to step 6:
73 divided by 12 is 6 with a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 57266.0
Subtracting 72 from 73 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
When dividing 10 by 12, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 57266.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
If we divide 100 by 12, we get 8 and a remainder of 4.
The next digit of our result is 8. 
Result so far: 57266.08
Subtract 96 from 100 to 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.

Advancing to step 9:
12 can be fit into 40 3 times, resulting in a remainder of 4.
The next digit of our result is 3. 
Result so far: 57266.083
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
12 can be fit into 40 3 times, resulting in a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 57266.0833
If we subtract 36 from 40, 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.

The quotient of the division is 57266.0833, and the remainder is 4e-05.
