We look at the division of 25853089 by 7 
We want to figure out the number of times 25853089 can be divided by 7.

Going ahead to step 1:
7 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 7

Let's proceed to step 2:
The number 7 fits into 25 3 times, leaving a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 21 from 25 to get 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 7

Going ahead to step 3:
48 divided by 7 is 6 with a remainder of 6.
The next digit of our result is 6. 
Result so far: 36.0
Subtract 42 from 48 to get 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 7

Let's proceed to step 4:
The number 7 fits into 65 9 times, leaving a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 369.0
Subtracting 63 from 65 leaves us with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 7

Going ahead to step 5:
7 goes into 23 3 times with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 3693.0
Deduct 21 from 23 and we're left with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 7

Moving on to step 6:
The number 7 fits into 20 2 times, leaving a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 36932.0
Subtract 14 from 20 to get 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 7

Moving on to step 7:
The number 7 fits into 68 9 times, leaving a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 369329.0
Subtract 63 from 68 to get 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 7

Step 8:
The number 7 fits into 59 8 times, leaving a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 3693298.0
Subtracting 56 from 59 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
7 can be fit into 30 4 times, resulting in a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 3693298.4
If we take 28 away from 30, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
The number 7 fits into 20 2 times, leaving a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 3693298.42
Subtracting 14 from 20 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 11:
When dividing 60 by 7, we get 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 3693298.428
Subtract 56 from 60 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 12:
7 can be fit into 40 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 3693298.4285
If we take 35 away from 40, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 13:
The number 7 fits into 50 7 times, leaving a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 3693298.42857
Deduct 49 from 50 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 14:
If we divide 10 by 7, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 3693298.428571
If we take 7 away from 10, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 15:
If we divide 30 by 7, we get 4 and a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 3693298.4285714
Subtract 28 from 30 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 16:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 3693298.42857142
The remainder is 6 after subtracting 14 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 3693298.42857142 with a remaining 6e-09.
