We look at the division of 201871 by 7 
We want to figure out the number of times 201871 can be divided by 7.

Going ahead to step 1:
7 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 7

Let's proceed to step 2:
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: 2.0
The remainder is 6 after subtracting 14 from 20.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 7

Moving on to step 3:
The number 7 fits into 61 8 times, leaving a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Deduct 56 from 61 and we're left with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 7

Advancing to step 4:
58 divided by 7 is 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 288.0
If we take 56 away from 58, we end up with 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 7

On to step 5:
27 divided by 7 is 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 2883.0
Deduct 21 from 27 and we're left with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 7

Let's proceed to step 6:
7 can be fit into 61 8 times, resulting in a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 28838.0
If we take 56 away from 61, 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.

Going ahead to step 7:
The number 7 fits into 50 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 28838.7
If we take 49 away from 50, we end up 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 goes into 10 1 times with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 28838.71
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:
30 divided by 7 is 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 28838.714
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.

Advancing to step 10:
7 can be fit into 20 2 times, resulting in a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 28838.7142
Subtract 14 from 20 to 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.

On to step 11:
When dividing 60 by 7, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 28838.71428
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.

Advancing to step 12:
7 goes into 40 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 28838.714285
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.

Advancing to step 13:
When dividing 50 by 7, we get 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 28838.7142857
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 14:
7 can be fit into 10 1 times, resulting in a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 28838.71428571
Deduct 7 from 10 and we're left 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.

Our division results in 28838.71428571 with a remaining 3e-09.
