We divide 842390 by 7
Let's see how many times 7 fits into 842390.

Step 1:
If we divide 8 by 7, we get 1 and a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 7 from 8 leaves us with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 7

Moving on to step 2:
7 goes into 14 2 times with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 14 away from 14, we end up with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 7

Let's proceed to step 3:
7 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 120.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 7

On to step 4:
7 can be fit into 23 3 times, resulting in a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 1203.0
The remainder is 2 after subtracting 21 from 23.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 7

Step 5:
When dividing 29 by 7, we get 4 with a remainder of 1.
The next digit of our result is 4. 
Result so far: 12034.0
Deduct 28 from 29 and we're left with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 7

Moving on to step 6:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 120341.0
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.

Advancing to step 7:
30 divided by 7 is 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 120341.4
Deduct 28 from 30 and we're left 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.

Moving on to step 8:
20 divided by 7 is 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 120341.42
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.

Advancing to step 9:
60 divided by 7 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 120341.428
If we take 56 away from 60, we end up 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 10:
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: 120341.4285
If we take 35 away from 40, we end up 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.

On to step 11:
7 can be fit into 50 7 times, resulting in a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 120341.42857
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.

Step 12:
10 divided by 7 is 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 120341.428571
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 13:
7 goes into 30 4 times with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 120341.4285714
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.

Step 14:
7 goes into 20 2 times with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 120341.42857142
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.

Our division results in 120341.42857142 with a remaining 6e-09.
