We look at the division of 64748100 by 321 
Let's see how many times 321 fits into 64748100.

On to step 1:
321 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 321

On to step 2:
If we divide 64 by 321, we get 0 and a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Append the next digit (7) from the dividend to 64 and continue with: 647 / 321

Moving on to step 3:
321 goes into 647 2 times with a remainder of 5.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 642 from 647 leaves us with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 321

Advancing to step 4:
54 divided by 321 is 0 with a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we subtract 0 from 54, we get 54.
Fetch the next digit (8) from the dividend, attach it to 54 and continue: 548 / 321

Let's proceed to step 5:
If we divide 548 by 321, we get 1 and a remainder of 227.
Put 1 as the next digit of the answer. 
Result so far: 201.0
If we subtract 321 from 548, we get 227.
Grab the next digit (1) from the dividend, add it to 227, then carry on: 2271 / 321

Step 6:
When dividing 2271 by 321, we get 7 with a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 2017.0
If we take 2247 away from 2271, we end up with 24.
Append the next digit (0) from the dividend to 24 and continue with: 240 / 321

On to step 7:
When dividing 240 by 321, we get 0 with a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 20170.0
Subtract 0 from 240 to get 240.
Bring next digit (0) of the dividend behind the 240 and repeat the process: 2400 / 321

Let's proceed to step 8:
321 goes into 2400 7 times with a remainder of 153.
Write down 7 as next digit of the result. 
Result so far: 201707.0
The remainder is 153 after subtracting 2247 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Advancing to step 9:
If we divide 1530 by 321, we get 4 and a remainder of 246.
The number 4 becomes the next digit in our result. 
Result so far: 201707.4
Subtract 1284 from 1530 to get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

On to step 10:
2460 divided by 321 is 7 with a remainder of 213.
Use 7 as the next digit of our solution. 
Result so far: 201707.47
Subtract 2247 from 2460 to get 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Moving on to step 11:
The number 321 fits into 2130 6 times, leaving a remainder of 204.
Put 6 as the next digit of the answer. 
Result so far: 201707.476
If we take 1926 away from 2130, we end up with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

On to step 12:
When dividing 2040 by 321, we get 6 with a remainder of 114.
Put 6 as the next digit of the answer. 
Result so far: 201707.4766
Subtracting 1926 from 2040 leaves us with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

The quotient of the division is 201707.4766, and the remainder is 0.00114.
