We divide 25861559 by 258
Our goal is to divide 25861559 by 258.

Step 1:
When dividing 2 by 258, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 258

Advancing to step 2:
When dividing 25 by 258, we get 0 with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Grab the next digit (8) from the dividend, add it to 25, then carry on: 258 / 258

Moving on to step 3:
The number 258 fits into 258 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 258 from 258, we get 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 258

On to step 4:
6 divided by 258 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 258

Advancing to step 5:
If we divide 61 by 258, we get 0 and a remainder of 61.
The next digit of our result is 0. 
Result so far: 100.0
Deduct 0 from 61 and we're left with 61.
Bring next digit (5) of the dividend behind the 61 and repeat the process: 615 / 258

Step 6:
258 goes into 615 2 times with a remainder of 99.
Use 2 as the next digit of our solution. 
Result so far: 1002.0
Subtracting 516 from 615 leaves us with 99.
Take the next digit (5) from the dividend and append it to 99, then repeat: 995 / 258

On to step 7:
When dividing 995 by 258, we get 3 with a remainder of 221.
Put 3 as the next digit of the answer. 
Result so far: 10023.0
Subtract 774 from 995 to get 221.
Take the next digit (9) from the dividend and append it to 221, then repeat: 2219 / 258

Moving on to step 8:
The number 258 fits into 2219 8 times, leaving a remainder of 155.
The next digit of our result is 8. 
Result so far: 100238.0
Deduct 2064 from 2219 and we're left with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Step 9:
The number 258 fits into 1550 6 times, leaving a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 100238.6
The remainder is 2 after subtracting 1548 from 1550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
258 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 100238.6
Subtracting 0 from 20 leaves us 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.

On to step 11:
The number 258 fits into 200 0 times, leaving a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 100238.6
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Our division results in 100238.6 with a remaining 0.02.
