We look at the division of 65423912 by 686 
We want to divide 65423912 by 686.

On to step 1:
686 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 686

Advancing to step 2:
65 divided by 686 is 0 with a remainder of 65.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 65 leaves us with 65.
Include the next digit (4) from the dividend after 65, then repeat: 654 / 686

On to step 3:
When dividing 654 by 686, we get 0 with a remainder of 654.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 654 leaves us with 654.
Grab the next digit (2) from the dividend, add it to 654, then carry on: 6542 / 686

Advancing to step 4:
The number 686 fits into 6542 9 times, leaving a remainder of 368.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 6174 from 6542 leaves us with 368.
Fetch the next digit (3) from the dividend, attach it to 368 and continue: 3683 / 686

Step 5:
The number 686 fits into 3683 5 times, leaving a remainder of 253.
Put 5 as the next digit of the answer. 
Result so far: 95.0
If we subtract 3430 from 3683, we get 253.
Append the next digit (9) from the dividend to 253 and continue with: 2539 / 686

On to step 6:
686 can be fit into 2539 3 times, resulting in a remainder of 481.
Record the quotient 3 as the next digit in the result. 
Result so far: 953.0
If we subtract 2058 from 2539, we get 481.
Fetch the next digit (1) from the dividend, attach it to 481 and continue: 4811 / 686

On to step 7:
686 can be fit into 4811 7 times, resulting in a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 9537.0
Deduct 4802 from 4811 and we're left with 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 686

Going ahead to step 8:
686 goes into 92 0 times with a remainder of 92.
Record the quotient 0 as the next digit in the result. 
Result so far: 95370.0
If we subtract 0 from 92, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 9:
If we divide 920 by 686, we get 1 and a remainder of 234.
The number 1 becomes the next digit in our result. 
Result so far: 95370.1
If we take 686 away from 920, we end up with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Moving on to step 10:
2340 divided by 686 is 3 with a remainder of 282.
The number 3 becomes the next digit in our result. 
Result so far: 95370.13
If we take 2058 away from 2340, we end up with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Moving on to step 11:
The number 686 fits into 2820 4 times, leaving a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 95370.134
Deduct 2744 from 2820 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 12:
686 goes into 760 1 times with a remainder of 74.
Use 1 as the next digit of our solution. 
Result so far: 95370.1341
If we take 686 away from 760, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 13:
686 goes into 740 1 times with a remainder of 54.
The next digit of our result is 1. 
Result so far: 95370.13411
If we take 686 away from 740, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final outcome is 95370.13411, with a leftover of 5.4e-05.
