We're dividing 255963 by 7 
Let's see how many times 7 fits into 255963.

Step 1:
The number 7 fits into 2 0 times, leaving 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.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 7

Moving on to step 2:
7 can be fit into 25 3 times, resulting in 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.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 7

On to step 3:
If we divide 45 by 7, we get 6 and a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 36.0
Subtracting 42 from 45 leaves us with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 7

Moving on to step 4:
7 can be fit into 39 5 times, resulting in a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 365.0
Subtracting 35 from 39 leaves us with 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 7

Step 5:
When dividing 46 by 7, we get 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 3656.0
Deduct 42 from 46 and we're left with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 7

Let's proceed to step 6:
When dividing 43 by 7, we get 6 with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 36566.0
Subtracting 42 from 43 leaves us 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.

Advancing to step 7:
When dividing 10 by 7, we get 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 36566.1
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.

On to step 8:
7 can be fit into 30 4 times, resulting in a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 36566.14
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.

Going ahead to step 9:
When dividing 20 by 7, we get 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 36566.142
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.

Going ahead to step 10:
7 can be fit into 60 8 times, resulting in a remainder of 4.
The next digit of our result is 8. 
Result so far: 36566.1428
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.

On to step 11:
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: 36566.14285
Subtract 35 from 40 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 12:
The number 7 fits into 50 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 36566.142857
If we subtract 49 from 50, we get 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 13:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 36566.1428571
Subtracting 7 from 10 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.

On to step 14:
30 divided by 7 is 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 36566.14285714
Deduct 28 from 30 and we're left 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.

Our division results in 36566.14285714 with a remaining 2e-09.
