We look at the division of 252458 by 7 
We're looking to find how many times 7 goes into 252458.

Let's proceed to step 1:
When dividing 2 by 7, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 7

Step 2:
7 can be fit into 25 3 times, resulting in a remainder of 4.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 21 from 25, we get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 7

Moving on to step 3:
7 goes into 42 6 times with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
If we take 42 away from 42, we end up with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 7

Going ahead to step 4:
If we divide 4 by 7, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 360.0
If we subtract 0 from 4, we get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 7

Moving on to step 5:
If we divide 45 by 7, we get 6 and a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 3606.0
Subtract 42 from 45 to get 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 7

Going ahead to step 6:
The number 7 fits into 38 5 times, leaving a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 36065.0
If we subtract 35 from 38, 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 7:
The number 7 fits into 30 4 times, leaving a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 36065.4
Subtracting 28 from 30 leaves us 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 8:
When dividing 20 by 7, we get 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 36065.42
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 9:
7 goes into 60 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 36065.428
Deduct 56 from 60 and we're left 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.

On to step 10:
If we divide 40 by 7, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 36065.4285
If we subtract 35 from 40, we 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.

Going ahead to step 11:
If we divide 50 by 7, we get 7 and a remainder of 1.
The next digit of our result is 7. 
Result so far: 36065.42857
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.

On to step 12:
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: 36065.428571
Subtract 7 from 10 to 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 13:
If we divide 30 by 7, we get 4 and a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 36065.4285714
Subtracting 28 from 30 leaves us 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 14:
When dividing 20 by 7, we get 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 36065.42857142
If we subtract 14 from 20, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

After the division, we end up with 36065.42857142 and a remainder of 6e-09.
