We're dividing 321810 by 48 
We want to figure out the number of times 321810 can be divided by 48.

Advancing to step 1:
If we divide 3 by 48, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 48

Moving on to step 2:
If we divide 32 by 48, we get 0 and a remainder of 32.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 32 to get 32.
Append the next digit (1) from the dividend to 32 and continue with: 321 / 48

Step 3:
If we divide 321 by 48, we get 6 and a remainder of 33.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 288 away from 321, we end up with 33.
Append the next digit (8) from the dividend to 33 and continue with: 338 / 48

Moving on to step 4:
48 goes into 338 7 times with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 67.0
Subtract 336 from 338 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 48

Moving on to step 5:
21 divided by 48 is 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 670.0
The remainder is 21 after subtracting 0 from 21.
Grab the next digit (0) from the dividend, add it to 21, then carry on: 210 / 48

Let's proceed to step 6:
The number 48 fits into 210 4 times, leaving a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 6704.0
Subtracting 192 from 210 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
The number 48 fits into 180 3 times, leaving a remainder of 36.
Put 3 as the next digit of the answer. 
Result so far: 6704.3
Subtract 144 from 180 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 8:
When dividing 360 by 48, we get 7 with a remainder of 24.
Write down 7 as next digit of the result. 
Result so far: 6704.37
The remainder is 24 after subtracting 336 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 9:
If we divide 240 by 48, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 6704.375
If we subtract 240 from 240, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
When dividing 0 by 48, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 6704.375
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
0 divided by 48 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6704.375
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 6704.375 with a remainder of 0.0.
