4654885 ÷ 686 
We want to divide 4654885 by 686.

On to step 1:
4 divided by 686 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 686

On to step 2:
The number 686 fits into 46 0 times, leaving a remainder of 46.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 46 after subtracting 0 from 46.
Include the next digit (5) from the dividend after 46, then repeat: 465 / 686

Going ahead to step 3:
686 can be fit into 465 0 times, resulting in a remainder of 465.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 465 to get 465.
Bring next digit (4) of the dividend behind the 465 and repeat the process: 4654 / 686

Moving on to step 4:
The number 686 fits into 4654 6 times, leaving a remainder of 538.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 4116 away from 4654, we end up with 538.
Take the next digit (8) from the dividend and append it to 538, then repeat: 5388 / 686

Step 5:
686 can be fit into 5388 7 times, resulting in a remainder of 586.
Write down 7 as next digit of the result. 
Result so far: 67.0
Deduct 4802 from 5388 and we're left with 586.
Take the next digit (8) from the dividend and append it to 586, then repeat: 5868 / 686

Moving on to step 6:
The number 686 fits into 5868 8 times, leaving a remainder of 380.
The next digit of our result is 8. 
Result so far: 678.0
Subtracting 5488 from 5868 leaves us with 380.
Grab the next digit (5) from the dividend, add it to 380, then carry on: 3805 / 686

Let's proceed to step 7:
The number 686 fits into 3805 5 times, leaving a remainder of 375.
Record the quotient 5 as the next digit in the result. 
Result so far: 6785.0
Subtracting 3430 from 3805 leaves us with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Advancing to step 8:
3750 divided by 686 is 5 with a remainder of 320.
Put 5 as the next digit of the answer. 
Result so far: 6785.5
Subtract 3430 from 3750 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 9:
The number 686 fits into 3200 4 times, leaving a remainder of 456.
Write down 4 as next digit of the result. 
Result so far: 6785.54
The remainder is 456 after subtracting 2744 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Step 10:
The number 686 fits into 4560 6 times, leaving a remainder of 444.
Record the quotient 6 as the next digit in the result. 
Result so far: 6785.546
Subtracting 4116 from 4560 leaves us with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Going ahead to step 11:
If we divide 4440 by 686, we get 6 and a remainder of 324.
The number 6 becomes the next digit in our result. 
Result so far: 6785.5466
Deduct 4116 from 4440 and we're left with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

The final result is 6785.5466 with a remainder of 0.00324.
