Let's divide 381858 by 15
Our goal is to divide 381858 by 15.

Advancing to step 1:
3 divided by 15 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
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 / 15

On to step 2:
The number 15 fits into 38 2 times, leaving a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 8 after subtracting 30 from 38.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 15

Step 3:
When dividing 81 by 15, we get 5 with a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 25.0
Deduct 75 from 81 and we're left with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 15

Moving on to step 4:
If we divide 68 by 15, we get 4 and a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 254.0
The remainder is 8 after subtracting 60 from 68.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 15

Let's proceed to step 5:
The number 15 fits into 85 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 2545.0
If we take 75 away from 85, we end up with 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 15

Going ahead to step 6:
15 can be fit into 108 7 times, resulting in a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 25457.0
Subtracting 105 from 108 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
15 can be fit into 30 2 times, resulting in a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 25457.2
Subtracting 30 from 30 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 8:
The number 15 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 25457.2
Subtract 0 from 0 to 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.

Step 9:
0 divided by 15 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 25457.2
Subtract 0 from 0 to 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.

After the division, we end up with 25457.2 and a remainder of 0.0.
