286238 ÷ 7 
We want to divide 286238 by 7.

Advancing to step 1:
The number 7 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 7

On to step 2:
If we divide 28 by 7, we get 4 and a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 28 from 28 leaves us with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 7

On to step 3:
6 divided by 7 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 40.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 7

Moving on to step 4:
62 divided by 7 is 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 408.0
The remainder is 6 after subtracting 56 from 62.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 7

Going ahead to step 5:
If we divide 63 by 7, we get 9 and a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 4089.0
The remainder is 0 after subtracting 63 from 63.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 7

Step 6:
7 goes into 8 1 times with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 40891.0
If we subtract 7 from 8, 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.

Let's proceed to step 7:
7 can be fit into 10 1 times, resulting in a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 40891.1
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.

Moving on to step 8:
7 goes into 30 4 times with a remainder of 2.
The next digit of our result is 4. 
Result so far: 40891.14
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.

Moving on to step 9:
7 can be fit into 20 2 times, resulting in a remainder of 6.
The next digit of our result is 2. 
Result so far: 40891.142
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.

Moving on to step 10:
7 can be fit into 60 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 40891.1428
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.

On to step 11:
7 goes into 40 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 40891.14285
Subtracting 35 from 40 leaves us 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 12:
The number 7 fits into 50 7 times, leaving a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 40891.142857
Subtract 49 from 50 to 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.

Let's proceed to step 13:
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: 40891.1428571
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.

Going ahead to step 14:
7 can be fit into 30 4 times, resulting in a remainder of 2.
The next digit of our result is 4. 
Result so far: 40891.14285714
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.

The final result is 40891.14285714 with a remainder of 2e-09.
