Let's divide 12879053 by 320
We're looking to find how many times 320 goes into 12879053.

Step 1:
1 divided by 320 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 320

Step 2:
The number 320 fits into 12 0 times, leaving a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 320

Step 3:
When dividing 128 by 320, we get 0 with a remainder of 128.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 128 and we're left with 128.
Take the next digit (7) from the dividend and append it to 128, then repeat: 1287 / 320

Moving on to step 4:
The number 320 fits into 1287 4 times, leaving a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 7 after subtracting 1280 from 1287.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 320

Moving on to step 5:
320 goes into 79 0 times with a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 40.0
The remainder is 79 after subtracting 0 from 79.
Append the next digit (0) from the dividend to 79 and continue with: 790 / 320

On to step 6:
When dividing 790 by 320, we get 2 with a remainder of 150.
Write down 2 as next digit of the result. 
Result so far: 402.0
Subtracting 640 from 790 leaves us with 150.
Fetch the next digit (5) from the dividend, attach it to 150 and continue: 1505 / 320

Advancing to step 7:
1505 divided by 320 is 4 with a remainder of 225.
Write down 4 as next digit of the result. 
Result so far: 4024.0
Subtracting 1280 from 1505 leaves us with 225.
Fetch the next digit (3) from the dividend, attach it to 225 and continue: 2253 / 320

Advancing to step 8:
The number 320 fits into 2253 7 times, leaving a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 40247.0
Subtract 2240 from 2253 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 9:
130 divided by 320 is 0 with a remainder of 130.
Write down 0 as next digit of the result. 
Result so far: 40247.0
If we take 0 away from 130, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 10:
1300 divided by 320 is 4 with a remainder of 20.
The next digit of our result is 4. 
Result so far: 40247.04
If we take 1280 away from 1300, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
The number 320 fits into 200 0 times, leaving a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 40247.04
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 12:
320 goes into 2000 6 times with a remainder of 80.
Put 6 as the next digit of the answer. 
Result so far: 40247.0406
If we subtract 1920 from 2000, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 13:
If we divide 800 by 320, we get 2 and a remainder of 160.
The next digit of our result is 2. 
Result so far: 40247.04062
Subtracting 640 from 800 leaves us 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.

Let's proceed to step 14:
320 goes into 1600 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 40247.040625
Deduct 1600 from 1600 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.

Step 15:
0 divided by 320 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 40247.040625
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 16:
320 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 40247.040625
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.

In conclusion, the division gives 40247.040625 with a balance of 0.0.
