4861865 divided by 320 
We want to figure out the number of times 4861865 can be divided by 320.

Step 1:
If we divide 4 by 320, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 320

Let's proceed to step 2:
The number 320 fits into 48 0 times, leaving a remainder of 48.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 48 after subtracting 0 from 48.
Bring next digit (6) of the dividend behind the 48 and repeat the process: 486 / 320

On to step 3:
486 divided by 320 is 1 with a remainder of 166.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 320 from 486, we get 166.
Include the next digit (1) from the dividend after 166, then repeat: 1661 / 320

Going ahead to step 4:
If we divide 1661 by 320, we get 5 and a remainder of 61.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Deduct 1600 from 1661 and we're left with 61.
Bring next digit (8) of the dividend behind the 61 and repeat the process: 618 / 320

Let's proceed to step 5:
320 can be fit into 618 1 times, resulting in a remainder of 298.
Record the quotient 1 as the next digit in the result. 
Result so far: 151.0
If we subtract 320 from 618, we get 298.
Bring next digit (6) of the dividend behind the 298 and repeat the process: 2986 / 320

Moving on to step 6:
320 goes into 2986 9 times with a remainder of 106.
Put 9 as the next digit of the answer. 
Result so far: 1519.0
If we take 2880 away from 2986, we end up with 106.
Grab the next digit (5) from the dividend, add it to 106, then carry on: 1065 / 320

Advancing to step 7:
320 goes into 1065 3 times with a remainder of 105.
Put 3 as the next digit of the answer. 
Result so far: 15193.0
If we subtract 960 from 1065, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Step 8:
320 can be fit into 1050 3 times, resulting in a remainder of 90.
The next digit of our result is 3. 
Result so far: 15193.3
If we subtract 960 from 1050, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 9:
When dividing 900 by 320, we get 2 with a remainder of 260.
Use 2 as the next digit of our solution. 
Result so far: 15193.32
Deduct 640 from 900 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 10:
2600 divided by 320 is 8 with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 15193.328
If we take 2560 away from 2600, we end up 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.

Advancing to step 11:
The number 320 fits into 400 1 times, leaving a remainder of 80.
Use 1 as the next digit of our solution. 
Result so far: 15193.3281
The remainder is 80 after subtracting 320 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 12:
320 can be fit into 800 2 times, resulting in a remainder of 160.
Put 2 as the next digit of the answer. 
Result so far: 15193.32812
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.

Going ahead to step 13:
The number 320 fits into 1600 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 15193.328125
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.

Step 14:
320 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 15193.328125
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.

On to step 15:
The number 320 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 15193.328125
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.

After the division, we end up with 15193.328125 and a remainder of 0.0.
