We look at the division of 25370007 by 878 
Our goal is to divide 25370007 by 878.

On to step 1:
When dividing 2 by 878, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 878

Moving on to step 2:
When dividing 25 by 878, we get 0 with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Include the next digit (3) from the dividend after 25, then repeat: 253 / 878

Step 3:
The number 878 fits into 253 0 times, leaving a remainder of 253.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 253, we get 253.
Fetch the next digit (7) from the dividend, attach it to 253 and continue: 2537 / 878

Step 4:
878 goes into 2537 2 times with a remainder of 781.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 1756 away from 2537, we end up with 781.
Include the next digit (0) from the dividend after 781, then repeat: 7810 / 878

Step 5:
878 goes into 7810 8 times with a remainder of 786.
Write down 8 as next digit of the result. 
Result so far: 28.0
Subtracting 7024 from 7810 leaves us with 786.
Fetch the next digit (0) from the dividend, attach it to 786 and continue: 7860 / 878

Going ahead to step 6:
The number 878 fits into 7860 8 times, leaving a remainder of 836.
The number 8 becomes the next digit in our result. 
Result so far: 288.0
Subtracting 7024 from 7860 leaves us with 836.
Bring next digit (0) of the dividend behind the 836 and repeat the process: 8360 / 878

Step 7:
878 can be fit into 8360 9 times, resulting in a remainder of 458.
Put 9 as the next digit of the answer. 
Result so far: 2889.0
Subtracting 7902 from 8360 leaves us with 458.
Include the next digit (7) from the dividend after 458, then repeat: 4587 / 878

Step 8:
878 goes into 4587 5 times with a remainder of 197.
Put 5 as the next digit of the answer. 
Result so far: 28895.0
If we subtract 4390 from 4587, we get 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Moving on to step 9:
When dividing 1970 by 878, we get 2 with a remainder of 214.
Put 2 as the next digit of the answer. 
Result so far: 28895.2
Subtract 1756 from 1970 to get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

On to step 10:
If we divide 2140 by 878, we get 2 and a remainder of 384.
Record the quotient 2 as the next digit in the result. 
Result so far: 28895.22
If we subtract 1756 from 2140, we get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

The final outcome is 28895.22, with a leftover of 0.384.
