Let's divide 96643735 by 321
We want to figure out the number of times 96643735 can be divided by 321.

Advancing to step 1:
The number 321 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 321

Advancing to step 2:
The number 321 fits into 96 0 times, leaving a remainder of 96.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 96 after subtracting 0 from 96.
Fetch the next digit (6) from the dividend, attach it to 96 and continue: 966 / 321

Going ahead to step 3:
When dividing 966 by 321, we get 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 963 from 966 leaves us with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 321

Let's proceed to step 4:
34 divided by 321 is 0 with a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
If we subtract 0 from 34, we get 34.
Bring next digit (3) of the dividend behind the 34 and repeat the process: 343 / 321

On to step 5:
The number 321 fits into 343 1 times, leaving a remainder of 22.
The next digit of our result is 1. 
Result so far: 301.0
If we subtract 321 from 343, we get 22.
Bring next digit (7) of the dividend behind the 22 and repeat the process: 227 / 321

Moving on to step 6:
The number 321 fits into 227 0 times, leaving a remainder of 227.
The next digit of our result is 0. 
Result so far: 3010.0
If we subtract 0 from 227, we get 227.
Take the next digit (3) from the dividend and append it to 227, then repeat: 2273 / 321

Let's proceed to step 7:
321 goes into 2273 7 times with a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 30107.0
Subtract 2247 from 2273 to get 26.
Bring next digit (5) of the dividend behind the 26 and repeat the process: 265 / 321

Advancing to step 8:
If we divide 265 by 321, we get 0 and a remainder of 265.
The number 0 becomes the next digit in our result. 
Result so far: 301070.0
If we take 0 away from 265, we end up with 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 9:
The number 321 fits into 2650 8 times, leaving a remainder of 82.
The next digit of our result is 8. 
Result so far: 301070.8
Subtracting 2568 from 2650 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 10:
If we divide 820 by 321, we get 2 and a remainder of 178.
Record the quotient 2 as the next digit in the result. 
Result so far: 301070.82
If we take 642 away from 820, we end up with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Going ahead to step 11:
321 goes into 1780 5 times with a remainder of 175.
Put 5 as the next digit of the answer. 
Result so far: 301070.825
Deduct 1605 from 1780 and we're left 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.

Advancing to step 12:
1750 divided by 321 is 5 with a remainder of 145.
Record the quotient 5 as the next digit in the result. 
Result so far: 301070.8255
Subtract 1605 from 1750 to get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

The quotient of the division is 301070.8255, and the remainder is 0.00145.
