We look at the division of 86349 by 25 
Our goal is to divide 86349 by 25.

Going ahead to step 1:
The number 25 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 25

Moving on to step 2:
When dividing 86 by 25, we get 3 with a remainder of 11.
The next digit of our result is 3. 
Result so far: 3.0
If we take 75 away from 86, we end up with 11.
Take the next digit (3) from the dividend and append it to 11, then repeat: 113 / 25

Advancing to step 3:
25 goes into 113 4 times with a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
Deduct 100 from 113 and we're left with 13.
Include the next digit (4) from the dividend after 13, then repeat: 134 / 25

Advancing to step 4:
When dividing 134 by 25, we get 5 with a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 345.0
The remainder is 9 after subtracting 125 from 134.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 25

Moving on to step 5:
25 can be fit into 99 3 times, resulting in a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 3453.0
The remainder is 24 after subtracting 75 from 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 6:
25 can be fit into 240 9 times, resulting in a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 3453.9
If we take 225 away from 240, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
25 can be fit into 150 6 times, resulting in a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 3453.96
Subtract 150 from 150 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.

Let's proceed to step 8:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3453.96
Deduct 0 from 0 and we're left 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 9:
25 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 3453.96
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.

The quotient of the division is 3453.96, and the remainder is 0.0.
