We look at the division of 25830016 by 860 
Let's see how many times 860 fits into 25830016.

Let's proceed to step 1:
860 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 860

Moving on to step 2:
If we divide 25 by 860, we get 0 and a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Append the next digit (8) from the dividend to 25 and continue with: 258 / 860

Moving on to step 3:
When dividing 258 by 860, we get 0 with a remainder of 258.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 258 and we're left with 258.
Bring next digit (3) of the dividend behind the 258 and repeat the process: 2583 / 860

Advancing to step 4:
If we divide 2583 by 860, we get 3 and a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 2580 from 2583 to get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 860

Let's proceed to step 5:
860 goes into 30 0 times with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
Deduct 0 from 30 and we're left with 30.
Fetch the next digit (0) from the dividend, attach it to 30 and continue: 300 / 860

Step 6:
If we divide 300 by 860, we get 0 and a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 300.0
Deduct 0 from 300 and we're left with 300.
Take the next digit (1) from the dividend and append it to 300, then repeat: 3001 / 860

Moving on to step 7:
When dividing 3001 by 860, we get 3 with a remainder of 421.
Use 3 as the next digit of our solution. 
Result so far: 3003.0
Subtracting 2580 from 3001 leaves us with 421.
Fetch the next digit (6) from the dividend, attach it to 421 and continue: 4216 / 860

Let's proceed to step 8:
860 goes into 4216 4 times with a remainder of 776.
The number 4 becomes the next digit in our result. 
Result so far: 30034.0
If we take 3440 away from 4216, we end up with 776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7760, and continue the process.

Advancing to step 9:
If we divide 7760 by 860, we get 9 and a remainder of 20.
Use 9 as the next digit of our solution. 
Result so far: 30034.9
Deduct 7740 from 7760 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
The number 860 fits into 200 0 times, leaving a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 30034.9
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 11:
When dividing 2000 by 860, we get 2 with a remainder of 280.
The next digit of our result is 2. 
Result so far: 30034.902
Deduct 1720 from 2000 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 12:
If we divide 2800 by 860, we get 3 and a remainder of 220.
Write down 3 as next digit of the result. 
Result so far: 30034.9023
Subtracting 2580 from 2800 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 13:
The number 860 fits into 2200 2 times, leaving a remainder of 480.
Write down 2 as next digit of the result. 
Result so far: 30034.90232
Subtract 1720 from 2200 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 14:
860 goes into 4800 5 times with a remainder of 500.
Put 5 as the next digit of the answer. 
Result so far: 30034.902325
Subtracting 4300 from 4800 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Moving on to step 15:
If we divide 5000 by 860, we get 5 and a remainder of 700.
Write down 5 as next digit of the result. 
Result so far: 30034.9023255
Deduct 4300 from 5000 and we're left with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

The final outcome is 30034.9023255, with a leftover of 7e-06.
