We look at the division of 78649824 by 320 
We're looking to find how many times 320 goes into 78649824.

Going ahead 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
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 320

Moving on to step 2:
320 can be fit into 78 0 times, resulting in a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Include the next digit (6) from the dividend after 78, then repeat: 786 / 320

Advancing to step 3:
When dividing 786 by 320, we get 2 with a remainder of 146.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 640 from 786 and we're left with 146.
Fetch the next digit (4) from the dividend, attach it to 146 and continue: 1464 / 320

Going ahead to step 4:
320 goes into 1464 4 times with a remainder of 184.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
If we subtract 1280 from 1464, we get 184.
Append the next digit (9) from the dividend to 184 and continue with: 1849 / 320

Let's proceed to step 5:
320 goes into 1849 5 times with a remainder of 249.
The number 5 becomes the next digit in our result. 
Result so far: 245.0
Subtract 1600 from 1849 to get 249.
Include the next digit (8) from the dividend after 249, then repeat: 2498 / 320

Going ahead to step 6:
If we divide 2498 by 320, we get 7 and a remainder of 258.
The number 7 becomes the next digit in our result. 
Result so far: 2457.0
Deduct 2240 from 2498 and we're left with 258.
Include the next digit (2) from the dividend after 258, then repeat: 2582 / 320

Advancing to step 7:
When dividing 2582 by 320, we get 8 with a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 24578.0
Deduct 2560 from 2582 and we're left with 22.
Append the next digit (4) from the dividend to 22 and continue with: 224 / 320

Advancing to step 8:
If we divide 224 by 320, we get 0 and a remainder of 224.
Use 0 as the next digit of our solution. 
Result so far: 245780.0
If we subtract 0 from 224, we get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Advancing to step 9:
When dividing 2240 by 320, we get 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 245780.7
Subtracting 2240 from 2240 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.

Let's proceed to step 10:
0 divided by 320 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 245780.7
Deduct 0 from 0 and we're left 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.

Moving on to step 11:
320 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 245780.7
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.

Our division results in 245780.7 with a remaining 0.0.
