25740896 divided by 858 
Let's see how many times 858 fits into 25740896.

On to step 1:
If we divide 2 by 858, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 858

Advancing to step 2:
858 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
The remainder is 25 after subtracting 0 from 25.
Grab the next digit (7) from the dividend, add it to 25, then carry on: 257 / 858

Moving on to step 3:
The number 858 fits into 257 0 times, leaving a remainder of 257.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 257, we get 257.
Include the next digit (4) from the dividend after 257, then repeat: 2574 / 858

Step 4:
When dividing 2574 by 858, we get 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 2574 from 2574 and we're left with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 858

Going ahead to step 5:
858 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
If we take 0 away from 0, we end up with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 858

Advancing to step 6:
When dividing 8 by 858, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 300.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 858

Step 7:
When dividing 89 by 858, we get 0 with a remainder of 89.
Put 0 as the next digit of the answer. 
Result so far: 3000.0
Subtract 0 from 89 to get 89.
Bring next digit (6) of the dividend behind the 89 and repeat the process: 896 / 858

Moving on to step 8:
858 goes into 896 1 times with a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 30001.0
If we subtract 858 from 896, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 9:
The number 858 fits into 380 0 times, leaving a remainder of 380.
Record the quotient 0 as the next digit in the result. 
Result so far: 30001.0
If we subtract 0 from 380, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 10:
The number 858 fits into 3800 4 times, leaving a remainder of 368.
Use 4 as the next digit of our solution. 
Result so far: 30001.04
If we take 3432 away from 3800, we end up with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Moving on to step 11:
858 can be fit into 3680 4 times, resulting in a remainder of 248.
The number 4 becomes the next digit in our result. 
Result so far: 30001.044
If we subtract 3432 from 3680, we get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

In conclusion, the division gives 30001.044 with a balance of 0.0248.
