78288035 ÷ 320 
Let's see how many times 320 fits into 78288035.

On to step 1:
If we divide 7 by 320, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 320

On to step 2:
If we divide 78 by 320, we get 0 and a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Fetch the next digit (2) from the dividend, attach it to 78 and continue: 782 / 320

Advancing to step 3:
782 divided by 320 is 2 with a remainder of 142.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 640 from 782, we get 142.
Bring next digit (8) of the dividend behind the 142 and repeat the process: 1428 / 320

Moving on to step 4:
If we divide 1428 by 320, we get 4 and a remainder of 148.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
Subtract 1280 from 1428 to get 148.
Include the next digit (8) from the dividend after 148, then repeat: 1488 / 320

On to step 5:
The number 320 fits into 1488 4 times, leaving a remainder of 208.
Put 4 as the next digit of the answer. 
Result so far: 244.0
If we subtract 1280 from 1488, we get 208.
Append the next digit (0) from the dividend to 208 and continue with: 2080 / 320

On to step 6:
If we divide 2080 by 320, we get 6 and a remainder of 160.
Put 6 as the next digit of the answer. 
Result so far: 2446.0
If we subtract 1920 from 2080, we get 160.
Grab the next digit (3) from the dividend, add it to 160, then carry on: 1603 / 320

Moving on to step 7:
320 goes into 1603 5 times with a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 24465.0
If we take 1600 away from 1603, we end up with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 320

On to step 8:
If we divide 35 by 320, we get 0 and a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 244650.0
The remainder is 35 after subtracting 0 from 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 9:
If we divide 350 by 320, we get 1 and a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 244650.1
If we take 320 away from 350, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
300 divided by 320 is 0 with a remainder of 300.
The next digit of our result is 0. 
Result so far: 244650.1
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 11:
3000 divided by 320 is 9 with a remainder of 120.
The next digit of our result is 9. 
Result so far: 244650.109
If we subtract 2880 from 3000, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 12:
The number 320 fits into 1200 3 times, leaving a remainder of 240.
The next digit of our result is 3. 
Result so far: 244650.1093
Subtract 960 from 1200 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 13:
320 goes into 2400 7 times with a remainder of 160.
The number 7 becomes the next digit in our result. 
Result so far: 244650.10937
The remainder is 160 after subtracting 2240 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 14:
320 can be fit into 1600 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 244650.109375
If we take 1600 away from 1600, we end up 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.

Let's proceed to step 15:
If we divide 0 by 320, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 244650.109375
Subtract 0 from 0 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 16:
The number 320 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 244650.109375
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.

The quotient of the division is 244650.109375, and the remainder is 0.0.
