25156830 ÷ 485 
Our goal is to divide 25156830 by 485.

Going ahead to step 1:
485 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 485

On to step 2:
25 divided by 485 is 0 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.
Grab the next digit (1) from the dividend, add it to 25, then carry on: 251 / 485

Moving on to step 3:
485 goes into 251 0 times with a remainder of 251.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 251 and we're left with 251.
Include the next digit (5) from the dividend after 251, then repeat: 2515 / 485

Let's proceed to step 4:
485 goes into 2515 5 times with a remainder of 90.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 2425 from 2515, we get 90.
Take the next digit (6) from the dividend and append it to 90, then repeat: 906 / 485

Moving on to step 5:
When dividing 906 by 485, we get 1 with a remainder of 421.
Use 1 as the next digit of our solution. 
Result so far: 51.0
Subtract 485 from 906 to get 421.
Take the next digit (8) from the dividend and append it to 421, then repeat: 4218 / 485

Step 6:
When dividing 4218 by 485, we get 8 with a remainder of 338.
Put 8 as the next digit of the answer. 
Result so far: 518.0
Subtracting 3880 from 4218 leaves us with 338.
Append the next digit (3) from the dividend to 338 and continue with: 3383 / 485

Moving on to step 7:
When dividing 3383 by 485, we get 6 with a remainder of 473.
The next digit of our result is 6. 
Result so far: 5186.0
Subtract 2910 from 3383 to get 473.
Take the next digit (0) from the dividend and append it to 473, then repeat: 4730 / 485

Let's proceed to step 8:
The number 485 fits into 4730 9 times, leaving a remainder of 365.
Write down 9 as next digit of the result. 
Result so far: 51869.0
Subtracting 4365 from 4730 leaves us with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

On to step 9:
485 goes into 3650 7 times with a remainder of 255.
The number 7 becomes the next digit in our result. 
Result so far: 51869.7
Subtract 3395 from 3650 to get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Let's proceed to step 10:
485 goes into 2550 5 times with a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 51869.75
Subtracting 2425 from 2550 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 11:
The number 485 fits into 1250 2 times, leaving a remainder of 280.
Use 2 as the next digit of our solution. 
Result so far: 51869.752
Subtract 970 from 1250 to get 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:
The number 485 fits into 2800 5 times, leaving a remainder of 375.
Record the quotient 5 as the next digit in the result. 
Result so far: 51869.7525
Subtracting 2425 from 2800 leaves us with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Let's proceed to step 13:
3750 divided by 485 is 7 with a remainder of 355.
Put 7 as the next digit of the answer. 
Result so far: 51869.75257
The remainder is 355 after subtracting 3395 from 3750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Step 14:
If we divide 3550 by 485, we get 7 and a remainder of 155.
Record the quotient 7 as the next digit in the result. 
Result so far: 51869.752577
The remainder is 155 after subtracting 3395 from 3550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

In conclusion, the division gives 51869.752577 with a balance of 1.55e-05.
