3868753 ÷ 258 
We want to divide 3868753 by 258.

On to step 1:
258 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 258

Moving on to step 2:
38 divided by 258 is 0 with a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Append the next digit (6) from the dividend to 38 and continue with: 386 / 258

On to step 3:
If we divide 386 by 258, we get 1 and a remainder of 128.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 258 from 386, we get 128.
Append the next digit (8) from the dividend to 128 and continue with: 1288 / 258

On to step 4:
1288 divided by 258 is 4 with a remainder of 256.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we subtract 1032 from 1288, we get 256.
Take the next digit (7) from the dividend and append it to 256, then repeat: 2567 / 258

Let's proceed to step 5:
2567 divided by 258 is 9 with a remainder of 245.
Write down 9 as next digit of the result. 
Result so far: 149.0
If we take 2322 away from 2567, we end up with 245.
Bring next digit (5) of the dividend behind the 245 and repeat the process: 2455 / 258

Step 6:
2455 divided by 258 is 9 with a remainder of 133.
Use 9 as the next digit of our solution. 
Result so far: 1499.0
Deduct 2322 from 2455 and we're left with 133.
Grab the next digit (3) from the dividend, add it to 133, then carry on: 1333 / 258

Step 7:
1333 divided by 258 is 5 with a remainder of 43.
Record the quotient 5 as the next digit in the result. 
Result so far: 14995.0
The remainder is 43 after subtracting 1290 from 1333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 8:
When dividing 430 by 258, we get 1 with a remainder of 172.
Use 1 as the next digit of our solution. 
Result so far: 14995.1
Subtract 258 from 430 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Advancing to step 9:
1720 divided by 258 is 6 with a remainder of 172.
Write down 6 as next digit of the result. 
Result so far: 14995.16
The remainder is 172 after subtracting 1548 from 1720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 10:
When dividing 1720 by 258, we get 6 with a remainder of 172.
The next digit of our result is 6. 
Result so far: 14995.166
Subtracting 1548 from 1720 leaves us with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

The final outcome is 14995.166, with a leftover of 0.0172.
