646466 ÷ 68 
Our goal is to divide 646466 by 68.

Step 1:
6 divided by 68 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 68

Advancing to step 2:
If we divide 64 by 68, we get 0 and a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Bring next digit (6) of the dividend behind the 64 and repeat the process: 646 / 68

Moving on to step 3:
If we divide 646 by 68, we get 9 and a remainder of 34.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 612 from 646 leaves us with 34.
Grab the next digit (4) from the dividend, add it to 34, then carry on: 344 / 68

Moving on to step 4:
When dividing 344 by 68, we get 5 with a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 95.0
The remainder is 4 after subtracting 340 from 344.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 68

Advancing to step 5:
If we divide 46 by 68, we get 0 and a remainder of 46.
The number 0 becomes the next digit in our result. 
Result so far: 950.0
Subtracting 0 from 46 leaves us with 46.
Grab the next digit (6) from the dividend, add it to 46, then carry on: 466 / 68

Let's proceed to step 6:
The number 68 fits into 466 6 times, leaving a remainder of 58.
Record the quotient 6 as the next digit in the result. 
Result so far: 9506.0
If we take 408 away from 466, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 7:
580 divided by 68 is 8 with a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 9506.8
Deduct 544 from 580 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 8:
When dividing 360 by 68, we get 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 9506.85
Subtract 340 from 360 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
When dividing 200 by 68, we get 2 with a remainder of 64.
The next digit of our result is 2. 
Result so far: 9506.852
The remainder is 64 after subtracting 136 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 10:
68 can be fit into 640 9 times, resulting in a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 9506.8529
Subtracting 612 from 640 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 11:
68 can be fit into 280 4 times, resulting in a remainder of 8.
The next digit of our result is 4. 
Result so far: 9506.85294
Subtract 272 from 280 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 12:
68 can be fit into 80 1 times, resulting in a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 9506.852941
Deduct 68 from 80 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 13:
When dividing 120 by 68, we get 1 with a remainder of 52.
The number 1 becomes the next digit in our result. 
Result so far: 9506.8529411
If we take 68 away from 120, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

After the division, we end up with 9506.8529411 and a remainder of 5.2e-07.
