Let's divide 64018489 by 321
We're looking to find how many times 321 goes into 64018489.

Moving on to step 1:
321 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 321

Let's proceed to step 2:
321 can be fit into 64 0 times, resulting in a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Append the next digit (0) from the dividend to 64 and continue with: 640 / 321

Let's proceed to step 3:
640 divided by 321 is 1 with a remainder of 319.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 321 from 640, we get 319.
Bring next digit (1) of the dividend behind the 319 and repeat the process: 3191 / 321

On to step 4:
321 goes into 3191 9 times with a remainder of 302.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtracting 2889 from 3191 leaves us with 302.
Include the next digit (8) from the dividend after 302, then repeat: 3028 / 321

Let's proceed to step 5:
321 can be fit into 3028 9 times, resulting in a remainder of 139.
Use 9 as the next digit of our solution. 
Result so far: 199.0
Deduct 2889 from 3028 and we're left with 139.
Take the next digit (4) from the dividend and append it to 139, then repeat: 1394 / 321

Going ahead to step 6:
321 can be fit into 1394 4 times, resulting in a remainder of 110.
Write down 4 as next digit of the result. 
Result so far: 1994.0
Deduct 1284 from 1394 and we're left with 110.
Take the next digit (8) from the dividend and append it to 110, then repeat: 1108 / 321

Moving on to step 7:
The number 321 fits into 1108 3 times, leaving a remainder of 145.
Put 3 as the next digit of the answer. 
Result so far: 19943.0
Subtracting 963 from 1108 leaves us with 145.
Append the next digit (9) from the dividend to 145 and continue with: 1459 / 321

On to step 8:
1459 divided by 321 is 4 with a remainder of 175.
Use 4 as the next digit of our solution. 
Result so far: 199434.0
If we take 1284 away from 1459, we end up with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 9:
321 goes into 1750 5 times with a remainder of 145.
Put 5 as the next digit of the answer. 
Result so far: 199434.5
Deduct 1605 from 1750 and we're left with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

On to step 10:
The number 321 fits into 1450 4 times, leaving a remainder of 166.
Use 4 as the next digit of our solution. 
Result so far: 199434.54
Deduct 1284 from 1450 and we're left with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Step 11:
The number 321 fits into 1660 5 times, leaving a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 199434.545
If we subtract 1605 from 1660, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 12:
321 goes into 550 1 times with a remainder of 229.
The next digit of our result is 1. 
Result so far: 199434.5451
Subtracting 321 from 550 leaves us with 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Advancing to step 13:
321 goes into 2290 7 times with a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 199434.54517
Deduct 2247 from 2290 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 14:
When dividing 430 by 321, we get 1 with a remainder of 109.
Write down 1 as next digit of the result. 
Result so far: 199434.545171
If we subtract 321 from 430, we get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Advancing to step 15:
1090 divided by 321 is 3 with a remainder of 127.
The next digit of our result is 3. 
Result so far: 199434.5451713
Subtracting 963 from 1090 leaves us with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Moving on to step 16:
When dividing 1270 by 321, we get 3 with a remainder of 307.
Record the quotient 3 as the next digit in the result. 
Result so far: 199434.54517133
If we take 963 away from 1270, we end up with 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

After the division, we end up with 199434.54517133 and a remainder of 3.07e-07.
