251891 ÷ 7 
We want to divide 251891 by 7.

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
Subtracting 0 from 2 leaves us with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 7

Moving on to step 2:
7 goes into 25 3 times with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 21 away from 25, we end up with 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 7

On to step 3:
41 divided by 7 is 5 with a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 35.0
The remainder is 6 after subtracting 35 from 41.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 7

Let's proceed to step 4:
7 goes into 68 9 times with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 359.0
The remainder is 5 after subtracting 63 from 68.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 7

Going ahead to step 5:
59 divided by 7 is 8 with a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 3598.0
If we subtract 56 from 59, we get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 7

Going ahead to step 6:
The number 7 fits into 31 4 times, leaving a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 35984.0
If we subtract 28 from 31, 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.

Advancing to step 7:
The number 7 fits into 30 4 times, leaving a remainder of 2.
The next digit of our result is 4. 
Result so far: 35984.4
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.

On to step 8:
20 divided by 7 is 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 35984.42
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.

Advancing to step 9:
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: 35984.428
The remainder is 4 after subtracting 56 from 60.
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 10:
When dividing 40 by 7, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 35984.4285
Subtract 35 from 40 to 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.

Moving on to step 11:
If we divide 50 by 7, we get 7 and a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 35984.42857
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.

Moving on to step 12:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 35984.428571
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.

Step 13:
When dividing 30 by 7, we get 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 35984.4285714
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 14:
If we divide 20 by 7, we get 2 and a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 35984.42857142
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 35984.42857142 and a remainder of 6e-09.
