Let's divide 843966 by 7
Let's see how many times 7 fits into 843966.

On to step 1:
7 goes into 8 1 times with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 7 from 8 to get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 7

Step 2:
If we divide 14 by 7, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 14 from 14 and we're left with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 7

Advancing to step 3:
7 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 120.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 7

Going ahead to step 4:
7 can be fit into 39 5 times, resulting in a remainder of 4.
The next digit of our result is 5. 
Result so far: 1205.0
Deduct 35 from 39 and we're left with 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 7

Let's proceed to step 5:
If we divide 46 by 7, we get 6 and a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 12056.0
Deduct 42 from 46 and we're left with 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 7

Going ahead to step 6:
46 divided by 7 is 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 120566.0
The remainder is 4 after subtracting 42 from 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
7 goes into 40 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 120566.5
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.

Step 8:
If we divide 50 by 7, we get 7 and a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 120566.57
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.

Advancing to step 9:
When dividing 10 by 7, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 120566.571
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.

On to step 10:
7 goes into 30 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 120566.5714
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.

On to step 11:
7 can be fit into 20 2 times, resulting in a remainder of 6.
The next digit of our result is 2. 
Result so far: 120566.57142
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:
If we divide 60 by 7, we get 8 and a remainder of 4.
The next digit of our result is 8. 
Result so far: 120566.571428
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.

Moving on to step 13:
7 goes into 40 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 120566.5714285
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.

Step 14:
50 divided by 7 is 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 120566.57142857
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.

The quotient of the division is 120566.57142857, and the remainder is 1e-09.
