25153239 ÷ 681 
We're looking to find how many times 681 goes into 25153239.

On to step 1:
The number 681 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.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 681

Going ahead to step 2:
When dividing 25 by 681, we get 0 with a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Fetch the next digit (1) from the dividend, attach it to 25 and continue: 251 / 681

On to step 3:
When dividing 251 by 681, we get 0 with a remainder of 251.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 251 after subtracting 0 from 251.
Fetch the next digit (5) from the dividend, attach it to 251 and continue: 2515 / 681

Moving on to step 4:
When dividing 2515 by 681, we get 3 with a remainder of 472.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 2043 away from 2515, we end up with 472.
Append the next digit (3) from the dividend to 472 and continue with: 4723 / 681

Moving on to step 5:
If we divide 4723 by 681, we get 6 and a remainder of 637.
Put 6 as the next digit of the answer. 
Result so far: 36.0
The remainder is 637 after subtracting 4086 from 4723.
Include the next digit (2) from the dividend after 637, then repeat: 6372 / 681

Let's proceed to step 6:
681 goes into 6372 9 times with a remainder of 243.
The number 9 becomes the next digit in our result. 
Result so far: 369.0
Subtracting 6129 from 6372 leaves us with 243.
Include the next digit (3) from the dividend after 243, then repeat: 2433 / 681

Advancing to step 7:
The number 681 fits into 2433 3 times, leaving a remainder of 390.
Write down 3 as next digit of the result. 
Result so far: 3693.0
The remainder is 390 after subtracting 2043 from 2433.
Grab the next digit (9) from the dividend, add it to 390, then carry on: 3909 / 681

Advancing to step 8:
The number 681 fits into 3909 5 times, leaving a remainder of 504.
The number 5 becomes the next digit in our result. 
Result so far: 36935.0
Deduct 3405 from 3909 and we're left with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Moving on to step 9:
681 goes into 5040 7 times with a remainder of 273.
The next digit of our result is 7. 
Result so far: 36935.7
Subtracting 4767 from 5040 leaves us with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

On to step 10:
681 can be fit into 2730 4 times, resulting in a remainder of 6.
The next digit of our result is 4. 
Result so far: 36935.74
Subtract 2724 from 2730 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 11:
681 can be fit into 60 0 times, resulting in a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 36935.74
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 12:
When dividing 600 by 681, we get 0 with a remainder of 600.
Record the quotient 0 as the next digit in the result. 
Result so far: 36935.74
The remainder is 600 after subtracting 0 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The final outcome is 36935.74, with a leftover of 0.006.
