25466039 ÷ 258 
We want to figure out the number of times 25466039 can be divided by 258.

Going ahead to step 1:
The number 258 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 258

Moving on to step 2:
258 goes into 25 0 times with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Include the next digit (4) from the dividend after 25, then repeat: 254 / 258

On to step 3:
258 goes into 254 0 times with a remainder of 254.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 254, we end up with 254.
Take the next digit (6) from the dividend and append it to 254, then repeat: 2546 / 258

Moving on to step 4:
If we divide 2546 by 258, we get 9 and a remainder of 224.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 2322 from 2546 to get 224.
Append the next digit (6) from the dividend to 224 and continue with: 2246 / 258

On to step 5:
The number 258 fits into 2246 8 times, leaving a remainder of 182.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
Deduct 2064 from 2246 and we're left with 182.
Grab the next digit (0) from the dividend, add it to 182, then carry on: 1820 / 258

Going ahead to step 6:
258 can be fit into 1820 7 times, resulting in a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 987.0
Deduct 1806 from 1820 and we're left with 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 258

Advancing to step 7:
258 goes into 143 0 times with a remainder of 143.
Write down 0 as next digit of the result. 
Result so far: 9870.0
Subtracting 0 from 143 leaves us with 143.
Fetch the next digit (9) from the dividend, attach it to 143 and continue: 1439 / 258

On to step 8:
If we divide 1439 by 258, we get 5 and a remainder of 149.
The next digit of our result is 5. 
Result so far: 98705.0
Subtracting 1290 from 1439 leaves us with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

On to step 9:
258 can be fit into 1490 5 times, resulting in a remainder of 200.
Write down 5 as next digit of the result. 
Result so far: 98705.5
If we subtract 1290 from 1490, we 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.

Moving on to step 10:
When dividing 2000 by 258, we get 7 with a remainder of 194.
Write down 7 as next digit of the result. 
Result so far: 98705.57
If we take 1806 away from 2000, we end up with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

On to step 11:
The number 258 fits into 1940 7 times, leaving a remainder of 134.
The next digit of our result is 7. 
Result so far: 98705.577
Deduct 1806 from 1940 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

After the division, we end up with 98705.577 and a remainder of 0.0134.
