4618861 ÷ 259 
Our goal is to divide 4618861 by 259.

On to step 1:
The number 259 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 259

Moving on to step 2:
If we divide 46 by 259, we get 0 and a remainder of 46.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 46 leaves us with 46.
Include the next digit (1) from the dividend after 46, then repeat: 461 / 259

On to step 3:
If we divide 461 by 259, we get 1 and a remainder of 202.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 259 from 461 and we're left with 202.
Append the next digit (8) from the dividend to 202 and continue with: 2028 / 259

Let's proceed to step 4:
If we divide 2028 by 259, we get 7 and a remainder of 215.
The next digit of our result is 7. 
Result so far: 17.0
If we subtract 1813 from 2028, we get 215.
Bring next digit (8) of the dividend behind the 215 and repeat the process: 2158 / 259

Advancing to step 5:
2158 divided by 259 is 8 with a remainder of 86.
Put 8 as the next digit of the answer. 
Result so far: 178.0
If we subtract 2072 from 2158, we get 86.
Grab the next digit (6) from the dividend, add it to 86, then carry on: 866 / 259

Step 6:
259 goes into 866 3 times with a remainder of 89.
Write down 3 as next digit of the result. 
Result so far: 1783.0
If we take 777 away from 866, we end up with 89.
Append the next digit (1) from the dividend to 89 and continue with: 891 / 259

Let's proceed to step 7:
891 divided by 259 is 3 with a remainder of 114.
Write down 3 as next digit of the result. 
Result so far: 17833.0
The remainder is 114 after subtracting 777 from 891.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Let's proceed to step 8:
259 can be fit into 1140 4 times, resulting in a remainder of 104.
The next digit of our result is 4. 
Result so far: 17833.4
Deduct 1036 from 1140 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 9:
The number 259 fits into 1040 4 times, leaving a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 17833.44
The remainder is 4 after subtracting 1036 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 17833.44, with a leftover of 0.004.
