286883 ÷ 7 
We want to divide 286883 by 7.

Step 1:
The number 7 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 7

On to step 2:
7 goes into 28 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 28 from 28, we get 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 7

Going ahead to step 3:
If we divide 6 by 7, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 40.0
If we take 0 away from 6, we end up with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 7

Advancing to step 4:
7 goes into 68 9 times with a remainder of 5.
The next digit of our result is 9. 
Result so far: 409.0
If we subtract 63 from 68, we get 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 7

Let's proceed to step 5:
7 goes into 58 8 times with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 4098.0
Deduct 56 from 58 and we're left with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 7

Going ahead to step 6:
23 divided by 7 is 3 with a remainder of 2.
The next digit of our result is 3. 
Result so far: 40983.0
If we take 21 away from 23, 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 7:
When dividing 20 by 7, we get 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 40983.2
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.

Advancing to step 8:
If we divide 60 by 7, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 40983.28
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.

Advancing to step 9:
If we divide 40 by 7, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 40983.285
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 10:
7 can be fit into 50 7 times, resulting in a remainder of 1.
The next digit of our result is 7. 
Result so far: 40983.2857
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.

On to step 11:
When dividing 10 by 7, we get 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 40983.28571
If we subtract 7 from 10, 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.

Step 12:
If we divide 30 by 7, we get 4 and a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 40983.285714
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.

Let's proceed to step 13:
The number 7 fits into 20 2 times, leaving a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 40983.2857142
If we take 14 away from 20, we end up 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 14:
If we divide 60 by 7, we get 8 and a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 40983.28571428
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.

The final outcome is 40983.28571428, with a leftover of 4e-09.
