We look at the division of 251157 by 7 
We want to figure out the number of times 251157 can be divided by 7.

Step 1:
7 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 7

Moving on to step 2:
When dividing 25 by 7, we get 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 21 from 25, we get 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 7

Let's proceed to step 3:
If we divide 41 by 7, we get 5 and a remainder of 6.
The next digit of our result is 5. 
Result so far: 35.0
The remainder is 6 after subtracting 35 from 41.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 7

On to step 4:
If we divide 61 by 7, we get 8 and a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 358.0
The remainder is 5 after subtracting 56 from 61.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 7

Moving on to step 5:
When dividing 55 by 7, we get 7 with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 3587.0
Subtracting 49 from 55 leaves us with 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 7

Advancing to step 6:
7 can be fit into 67 9 times, resulting in a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 35879.0
Subtracting 63 from 67 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.

Going ahead to step 7:
The number 7 fits into 40 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 35879.5
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 8:
50 divided by 7 is 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 35879.57
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.

Moving on to step 9:
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: 35879.571
The remainder is 3 after subtracting 7 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 10:
30 divided by 7 is 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 35879.5714
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.

Advancing to step 11:
7 goes into 20 2 times with a remainder of 6.
The next digit of our result is 2. 
Result so far: 35879.57142
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 12:
If we divide 60 by 7, we get 8 and a remainder of 4.
The next digit of our result is 8. 
Result so far: 35879.571428
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 13:
If we divide 40 by 7, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 35879.5714285
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.

Moving on to step 14:
The number 7 fits into 50 7 times, leaving a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 35879.57142857
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.

The quotient of the division is 35879.57142857, and the remainder is 1e-09.
