Let's divide 25199678 by 807
Our goal is to divide 25199678 by 807.

Step 1:
2 divided by 807 is 0 with 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.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 807

Moving on to step 2:
25 divided by 807 is 0 with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Grab the next digit (1) from the dividend, add it to 25, then carry on: 251 / 807

Step 3:
251 divided by 807 is 0 with a remainder of 251.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 251, we end up with 251.
Fetch the next digit (9) from the dividend, attach it to 251 and continue: 2519 / 807

Going ahead to step 4:
When dividing 2519 by 807, we get 3 with a remainder of 98.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 2421 away from 2519, we end up with 98.
Grab the next digit (9) from the dividend, add it to 98, then carry on: 989 / 807

Let's proceed to step 5:
807 can be fit into 989 1 times, resulting in a remainder of 182.
The next digit of our result is 1. 
Result so far: 31.0
Subtracting 807 from 989 leaves us with 182.
Grab the next digit (6) from the dividend, add it to 182, then carry on: 1826 / 807

On to step 6:
807 goes into 1826 2 times with a remainder of 212.
Write down 2 as next digit of the result. 
Result so far: 312.0
Deduct 1614 from 1826 and we're left with 212.
Fetch the next digit (7) from the dividend, attach it to 212 and continue: 2127 / 807

Let's proceed to step 7:
2127 divided by 807 is 2 with a remainder of 513.
The number 2 becomes the next digit in our result. 
Result so far: 3122.0
If we take 1614 away from 2127, we end up with 513.
Fetch the next digit (8) from the dividend, attach it to 513 and continue: 5138 / 807

Let's proceed to step 8:
807 goes into 5138 6 times with a remainder of 296.
Put 6 as the next digit of the answer. 
Result so far: 31226.0
Subtract 4842 from 5138 to get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Let's proceed to step 9:
2960 divided by 807 is 3 with a remainder of 539.
Put 3 as the next digit of the answer. 
Result so far: 31226.3
Subtracting 2421 from 2960 leaves us with 539.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5390, and continue the process.

Step 10:
5390 divided by 807 is 6 with a remainder of 548.
Write down 6 as next digit of the result. 
Result so far: 31226.36
If we take 4842 away from 5390, we end up with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Step 11:
When dividing 5480 by 807, we get 6 with a remainder of 638.
Write down 6 as next digit of the result. 
Result so far: 31226.366
The remainder is 638 after subtracting 4842 from 5480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

The final result is 31226.366 with a remainder of 0.0638.
