646486 ÷ 7 
We want to divide 646486 by 7.

Let's proceed to step 1:
7 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 7

Let's proceed to step 2:
7 goes into 64 9 times with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 63 from 64 and we're left with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 7

Moving on to step 3:
If we divide 16 by 7, we get 2 and a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 92.0
Subtract 14 from 16 to get 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 7

Let's proceed to step 4:
7 goes into 24 3 times with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 923.0
Subtracting 21 from 24 leaves us with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 7

Going ahead to step 5:
7 goes into 38 5 times with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 9235.0
If we subtract 35 from 38, we get 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 7

Going ahead to step 6:
7 goes into 36 5 times with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 92355.0
If we take 35 away from 36, we end up 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.

Let's proceed to step 7:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 92355.1
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.

On to step 8:
30 divided by 7 is 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 92355.14
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 9:
7 can be fit into 20 2 times, resulting in a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 92355.142
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.

Step 10:
7 can be fit into 60 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 92355.1428
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 11:
The number 7 fits into 40 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 92355.14285
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.

Step 12:
If we divide 50 by 7, we get 7 and a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 92355.142857
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 13:
If we divide 10 by 7, we get 1 and a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 92355.1428571
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 14:
When dividing 30 by 7, we get 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 92355.14285714
Subtracting 28 from 30 leaves us 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.

After the division, we end up with 92355.14285714 and a remainder of 2e-09.
