839603 ÷ 7 
Let's see how many times 7 fits into 839603.

Moving on to step 1:
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: 1.0
If we subtract 7 from 8, we get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 7

Going ahead to step 2:
When dividing 13 by 7, we get 1 with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 7 from 13 leaves us with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 7

Going ahead to step 3:
When dividing 69 by 7, we get 9 with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 119.0
If we take 63 away from 69, we end up with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 7

Step 4:
When dividing 66 by 7, we get 9 with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 1199.0
Deduct 63 from 66 and we're left with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 7

Let's proceed to step 5:
7 goes into 30 4 times with a remainder of 2.
The next digit of our result is 4. 
Result so far: 11994.0
Subtracting 28 from 30 leaves us with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 7

On to step 6:
7 goes into 23 3 times with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 119943.0
The remainder is 2 after subtracting 21 from 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
If we divide 20 by 7, we get 2 and a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 119943.2
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.

Moving on to step 8:
When dividing 60 by 7, we get 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 119943.28
If we subtract 56 from 60, we 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.

Going ahead to step 9:
When dividing 40 by 7, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 119943.285
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.

On to step 10:
If we divide 50 by 7, we get 7 and a remainder of 1.
The next digit of our result is 7. 
Result so far: 119943.2857
If we subtract 49 from 50, 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.

Going ahead to step 11:
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: 119943.28571
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 12:
7 goes into 30 4 times with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 119943.285714
If we subtract 28 from 30, we 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.

Moving on to step 13:
20 divided by 7 is 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 119943.2857142
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.

On to step 14:
7 goes into 60 8 times with a remainder of 4.
The next digit of our result is 8. 
Result so far: 119943.28571428
Deduct 56 from 60 and we're left 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.

The final result is 119943.28571428 with a remainder of 4e-09.
