We're dividing 251218 by 7 
Let's see how many times 7 fits into 251218.

Step 1:
7 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
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 / 7

Let's proceed to step 2:
The number 7 fits into 25 3 times, leaving a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 21 from 25 leaves us with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 7

Moving on to step 3:
7 can be fit into 41 5 times, resulting in a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
Subtracting 35 from 41 leaves us with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 7

Step 4:
62 divided by 7 is 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 358.0
Deduct 56 from 62 and we're left with 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 7

Step 5:
The number 7 fits into 61 8 times, leaving a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 3588.0
The remainder is 5 after subtracting 56 from 61.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 7

Step 6:
When dividing 58 by 7, we get 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 35888.0
If we take 56 away from 58, 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 7:
If we divide 20 by 7, we get 2 and a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 35888.2
Deduct 14 from 20 and we're left 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 8:
When dividing 60 by 7, we get 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 35888.28
If we take 56 away from 60, we end up with 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 9:
7 goes into 40 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 35888.285
Deduct 35 from 40 and we're left 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.

Advancing to step 10:
7 goes into 50 7 times with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 35888.2857
Subtract 49 from 50 to 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.

Advancing to step 11:
When dividing 10 by 7, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 35888.28571
If we subtract 7 from 10, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 12:
30 divided by 7 is 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 35888.285714
The remainder is 2 after subtracting 28 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 13:
If we divide 20 by 7, we get 2 and a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 35888.2857142
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.

Going ahead to step 14:
If we divide 60 by 7, we get 8 and a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 35888.28571428
If we take 56 away from 60, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 35888.28571428 with a remaining 4e-09.
