We look at the division of 25587069 by 684 
We want to divide 25587069 by 684.

Moving on to step 1:
684 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 684

Going ahead to step 2:
The number 684 fits into 25 0 times, leaving a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Append the next digit (5) from the dividend to 25 and continue with: 255 / 684

Going ahead to step 3:
684 can be fit into 255 0 times, resulting in a remainder of 255.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 255 leaves us with 255.
Include the next digit (8) from the dividend after 255, then repeat: 2558 / 684

Moving on to step 4:
When dividing 2558 by 684, we get 3 with a remainder of 506.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 2052 from 2558, we get 506.
Include the next digit (7) from the dividend after 506, then repeat: 5067 / 684

Step 5:
When dividing 5067 by 684, we get 7 with a remainder of 279.
The next digit of our result is 7. 
Result so far: 37.0
Subtracting 4788 from 5067 leaves us with 279.
Grab the next digit (0) from the dividend, add it to 279, then carry on: 2790 / 684

On to step 6:
When dividing 2790 by 684, we get 4 with a remainder of 54.
The number 4 becomes the next digit in our result. 
Result so far: 374.0
Subtracting 2736 from 2790 leaves us with 54.
Bring next digit (6) of the dividend behind the 54 and repeat the process: 546 / 684

On to step 7:
When dividing 546 by 684, we get 0 with a remainder of 546.
Write down 0 as next digit of the result. 
Result so far: 3740.0
Subtract 0 from 546 to get 546.
Grab the next digit (9) from the dividend, add it to 546, then carry on: 5469 / 684

Moving on to step 8:
684 goes into 5469 7 times with a remainder of 681.
Write down 7 as next digit of the result. 
Result so far: 37407.0
If we subtract 4788 from 5469, we get 681.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6810, and continue the process.

Advancing to step 9:
684 goes into 6810 9 times with a remainder of 654.
Use 9 as the next digit of our solution. 
Result so far: 37407.9
If we take 6156 away from 6810, we end up with 654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Advancing to step 10:
6540 divided by 684 is 9 with a remainder of 384.
Put 9 as the next digit of the answer. 
Result so far: 37407.99
If we take 6156 away from 6540, we end up with 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 37407.99, with a leftover of 0.384.
