321551 ÷ 68 
Our goal is to divide 321551 by 68.

Going ahead to step 1:
68 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 68

Moving on to step 2:
32 divided by 68 is 0 with a remainder of 32.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 32, we get 32.
Grab the next digit (1) from the dividend, add it to 32, then carry on: 321 / 68

Let's proceed to step 3:
When dividing 321 by 68, we get 4 with a remainder of 49.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 272 away from 321, we end up with 49.
Append the next digit (5) from the dividend to 49 and continue with: 495 / 68

Moving on to step 4:
68 can be fit into 495 7 times, resulting in a remainder of 19.
The next digit of our result is 7. 
Result so far: 47.0
If we subtract 476 from 495, we get 19.
Append the next digit (5) from the dividend to 19 and continue with: 195 / 68

On to step 5:
195 divided by 68 is 2 with a remainder of 59.
The next digit of our result is 2. 
Result so far: 472.0
The remainder is 59 after subtracting 136 from 195.
Grab the next digit (1) from the dividend, add it to 59, then carry on: 591 / 68

Moving on to step 6:
The number 68 fits into 591 8 times, leaving a remainder of 47.
Write down 8 as next digit of the result. 
Result so far: 4728.0
If we take 544 away from 591, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 7:
If we divide 470 by 68, we get 6 and a remainder of 62.
Use 6 as the next digit of our solution. 
Result so far: 4728.6
If we take 408 away from 470, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 8:
68 goes into 620 9 times with a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 4728.69
The remainder is 8 after subtracting 612 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
80 divided by 68 is 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 4728.691
The remainder is 12 after subtracting 68 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
The number 68 fits into 120 1 times, leaving a remainder of 52.
Put 1 as the next digit of the answer. 
Result so far: 4728.6911
The remainder is 52 after subtracting 68 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Our division results in 4728.6911 with a remaining 0.00052.
