64280428 ÷ 329 
We want to figure out the number of times 64280428 can be divided by 329.

Let's proceed to step 1:
6 divided by 329 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 329

Advancing to step 2:
329 can be fit into 64 0 times, resulting in a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Include the next digit (2) from the dividend after 64, then repeat: 642 / 329

Step 3:
329 goes into 642 1 times with a remainder of 313.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 329 from 642, we get 313.
Grab the next digit (8) from the dividend, add it to 313, then carry on: 3138 / 329

Moving on to step 4:
329 can be fit into 3138 9 times, resulting in a remainder of 177.
The next digit of our result is 9. 
Result so far: 19.0
Subtract 2961 from 3138 to get 177.
Grab the next digit (0) from the dividend, add it to 177, then carry on: 1770 / 329

On to step 5:
If we divide 1770 by 329, we get 5 and a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 195.0
Subtracting 1645 from 1770 leaves us with 125.
Include the next digit (4) from the dividend after 125, then repeat: 1254 / 329

Let's proceed to step 6:
1254 divided by 329 is 3 with a remainder of 267.
Record the quotient 3 as the next digit in the result. 
Result so far: 1953.0
If we take 987 away from 1254, we end up with 267.
Take the next digit (2) from the dividend and append it to 267, then repeat: 2672 / 329

Step 7:
329 goes into 2672 8 times with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 19538.0
Deduct 2632 from 2672 and we're left with 40.
Grab the next digit (8) from the dividend, add it to 40, then carry on: 408 / 329

Moving on to step 8:
If we divide 408 by 329, we get 1 and a remainder of 79.
Write down 1 as next digit of the result. 
Result so far: 195381.0
Subtract 329 from 408 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 9:
329 goes into 790 2 times with a remainder of 132.
Write down 2 as next digit of the result. 
Result so far: 195381.2
Subtracting 658 from 790 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Advancing to step 10:
The number 329 fits into 1320 4 times, leaving a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 195381.24
If we take 1316 away from 1320, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
329 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 195381.24
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 12:
329 goes into 400 1 times with a remainder of 71.
Put 1 as the next digit of the answer. 
Result so far: 195381.2401
If we subtract 329 from 400, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 13:
If we divide 710 by 329, we get 2 and a remainder of 52.
Use 2 as the next digit of our solution. 
Result so far: 195381.24012
Subtracting 658 from 710 leaves us 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.

On to step 14:
329 goes into 520 1 times with a remainder of 191.
Write down 1 as next digit of the result. 
Result so far: 195381.240121
The remainder is 191 after subtracting 329 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Let's proceed to step 15:
1910 divided by 329 is 5 with a remainder of 265.
Record the quotient 5 as the next digit in the result. 
Result so far: 195381.2401215
Subtract 1645 from 1910 to get 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Advancing to step 16:
329 can be fit into 2650 8 times, resulting in a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 195381.24012158
Deduct 2632 from 2650 and we're left 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.

Our division results in 195381.24012158 with a remaining 1.8e-08.
