We're dividing 904678 by 7 
Let's see how many times 7 fits into 904678.

Going ahead to step 1:
If we divide 9 by 7, we get 1 and a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 2 after subtracting 7 from 9.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 7

Step 2:
If we divide 20 by 7, we get 2 and a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 14 from 20 to get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 7

Step 3:
When dividing 64 by 7, we get 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 129.0
Deduct 63 from 64 and we're left with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 7

On to step 4:
7 can be fit into 16 2 times, resulting in a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 1292.0
Deduct 14 from 16 and we're left with 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 7

Advancing to step 5:
When dividing 27 by 7, we get 3 with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 12923.0
The remainder is 6 after subtracting 21 from 27.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 7

Moving on to step 6:
If we divide 68 by 7, we get 9 and a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 129239.0
Subtract 63 from 68 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.

Going ahead to step 7:
The number 7 fits into 50 7 times, leaving a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 129239.7
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 8:
7 goes into 10 1 times with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 129239.71
The remainder is 3 after subtracting 7 from 10.
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 9:
30 divided by 7 is 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 129239.714
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.

Advancing to step 10:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 129239.7142
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 11:
When dividing 60 by 7, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 129239.71428
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 12:
If we divide 40 by 7, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 129239.714285
If we subtract 35 from 40, we 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 13:
7 can be fit into 50 7 times, resulting in a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 129239.7142857
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.

Going ahead to step 14:
10 divided by 7 is 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 129239.71428571
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.

The final result is 129239.71428571 with a remainder of 3e-09.
