309019 ÷ 7 
We want to divide 309019 by 7.

Going ahead to step 1:
When dividing 3 by 7, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 7

Moving on to step 2:
The number 7 fits into 30 4 times, leaving a remainder of 2.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 2 after subtracting 28 from 30.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 7

On to step 3:
If we divide 29 by 7, we get 4 and a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 44.0
Subtract 28 from 29 to get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 7

On to step 4:
If we divide 10 by 7, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 441.0
If we subtract 7 from 10, we get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 7

Let's proceed to step 5:
31 divided by 7 is 4 with a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 4414.0
If we take 28 away from 31, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 7

Advancing to step 6:
7 can be fit into 39 5 times, resulting in a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 44145.0
The remainder is 4 after subtracting 35 from 39.
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 7:
40 divided by 7 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 44145.5
The remainder is 5 after subtracting 35 from 40.
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 8:
When dividing 50 by 7, we get 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 44145.57
The remainder is 1 after subtracting 49 from 50.
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 9:
If we divide 10 by 7, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 44145.571
If we take 7 away from 10, we end up 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.

Let's proceed to step 10:
If we divide 30 by 7, we get 4 and a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 44145.5714
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.

On to step 11:
7 goes into 20 2 times with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 44145.57142
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.

Step 12:
The number 7 fits into 60 8 times, leaving a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 44145.571428
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.

Let's proceed to step 13:
When dividing 40 by 7, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 44145.5714285
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.

Step 14:
7 goes into 50 7 times with a remainder of 1.
The next digit of our result is 7. 
Result so far: 44145.57142857
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.

After the division, we end up with 44145.57142857 and a remainder of 1e-09.
