We divide 4473888 by 320
Let's see how many times 320 fits into 4473888.

On to step 1:
320 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 320

Step 2:
320 can be fit into 44 0 times, resulting in a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 44 to get 44.
Take the next digit (7) from the dividend and append it to 44, then repeat: 447 / 320

Step 3:
The number 320 fits into 447 1 times, leaving a remainder of 127.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 320 from 447 and we're left with 127.
Append the next digit (3) from the dividend to 127 and continue with: 1273 / 320

Step 4:
320 can be fit into 1273 3 times, resulting in a remainder of 313.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 313 after subtracting 960 from 1273.
Include the next digit (8) from the dividend after 313, then repeat: 3138 / 320

Moving on to step 5:
When dividing 3138 by 320, we get 9 with a remainder of 258.
Put 9 as the next digit of the answer. 
Result so far: 139.0
The remainder is 258 after subtracting 2880 from 3138.
Take the next digit (8) from the dividend and append it to 258, then repeat: 2588 / 320

Advancing to step 6:
320 goes into 2588 8 times with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 1398.0
Subtract 2560 from 2588 to get 28.
Fetch the next digit (8) from the dividend, attach it to 28 and continue: 288 / 320

Advancing to step 7:
The number 320 fits into 288 0 times, leaving a remainder of 288.
The number 0 becomes the next digit in our result. 
Result so far: 13980.0
Subtracting 0 from 288 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

On to step 8:
320 can be fit into 2880 9 times, resulting in a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 13980.9
If we subtract 2880 from 2880, 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.

Advancing to step 9:
0 divided by 320 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 13980.9
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.

Let's proceed to step 10:
When dividing 0 by 320, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 13980.9
If we take 0 away from 0, 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.

After the division, we end up with 13980.9 and a remainder of 0.0.
