Let's divide 252257 by 7
We want to figure out the number of times 252257 can be divided by 7.

Going ahead to step 1:
The number 7 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 7

Moving on to step 2:
7 goes into 25 3 times with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 21 from 25 and we're left with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 7

Going ahead to step 3:
When dividing 42 by 7, we get 6 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.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 7

On to step 4:
2 divided by 7 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 360.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 7

Advancing to step 5:
If we divide 25 by 7, we get 3 and a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 3603.0
Subtract 21 from 25 to get 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 7

On to step 6:
When dividing 47 by 7, we get 6 with a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 36036.0
Deduct 42 from 47 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.

Step 7:
50 divided by 7 is 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 36036.7
Subtracting 49 from 50 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.

On to step 8:
7 can be fit into 10 1 times, resulting in a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 36036.71
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.

On to step 9:
If we divide 30 by 7, we get 4 and a remainder of 2.
The next digit of our result is 4. 
Result so far: 36036.714
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.

Step 10:
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: 36036.7142
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.

On to step 11:
When dividing 60 by 7, we get 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 36036.71428
Subtracting 56 from 60 leaves us 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.

Moving on 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: 36036.714285
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 13:
7 goes into 50 7 times with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 36036.7142857
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.

Moving on to step 14:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 36036.71428571
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.

In conclusion, the division gives 36036.71428571 with a balance of 3e-09.
