72099204 divided by 320 
Our goal is to divide 72099204 by 320.

Let's proceed to step 1:
If we divide 7 by 320, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 320

Step 2:
If we divide 72 by 320, we get 0 and a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Bring next digit (0) of the dividend behind the 72 and repeat the process: 720 / 320

Moving on to step 3:
If we divide 720 by 320, we get 2 and a remainder of 80.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 640 from 720 to get 80.
Append the next digit (9) from the dividend to 80 and continue with: 809 / 320

Moving on to step 4:
The number 320 fits into 809 2 times, leaving a remainder of 169.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Subtracting 640 from 809 leaves us with 169.
Bring next digit (9) of the dividend behind the 169 and repeat the process: 1699 / 320

Advancing to step 5:
When dividing 1699 by 320, we get 5 with a remainder of 99.
Record the quotient 5 as the next digit in the result. 
Result so far: 225.0
The remainder is 99 after subtracting 1600 from 1699.
Include the next digit (2) from the dividend after 99, then repeat: 992 / 320

On to step 6:
992 divided by 320 is 3 with a remainder of 32.
Use 3 as the next digit of our solution. 
Result so far: 2253.0
If we take 960 away from 992, we end up with 32.
Append the next digit (0) from the dividend to 32 and continue with: 320 / 320

On to step 7:
320 can be fit into 320 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 22531.0
Deduct 320 from 320 and we're left with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 320

Step 8:
If we divide 4 by 320, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 225310.0
The remainder is 4 after subtracting 0 from 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
320 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 225310.0
Deduct 0 from 40 and we're left with 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 10:
400 divided by 320 is 1 with a remainder of 80.
The next digit of our result is 1. 
Result so far: 225310.01
If we take 320 away from 400, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 11:
800 divided by 320 is 2 with a remainder of 160.
The next digit of our result is 2. 
Result so far: 225310.012
Deduct 640 from 800 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 12:
320 can be fit into 1600 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 225310.0125
Subtract 1600 from 1600 to 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.

Advancing to step 13:
0 divided by 320 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 225310.0125
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.

Going ahead to step 14:
0 divided by 320 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 225310.0125
If we subtract 0 from 0, 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.

The quotient of the division is 225310.0125, and the remainder is 0.0.
