645287 ÷ 7 
Let's see how many times 7 fits into 645287.

On to step 1:
7 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 7

Advancing to step 2:
64 divided by 7 is 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 63 from 64 to get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 7

Going ahead to step 3:
15 divided by 7 is 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 92.0
Subtracting 14 from 15 leaves us with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 7

Moving on to step 4:
12 divided by 7 is 1 with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 921.0
Deduct 7 from 12 and we're left with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 7

Going ahead to step 5:
7 can be fit into 58 8 times, resulting in a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 9218.0
Deduct 56 from 58 and we're left with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 7

Moving on to step 6:
27 divided by 7 is 3 with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 92183.0
If we take 21 away from 27, 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.

On to step 7:
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: 92183.8
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.

Let's proceed to step 8:
If we divide 40 by 7, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 92183.85
Subtracting 35 from 40 leaves us 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 9:
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: 92183.857
If we take 49 away from 50, 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.

Moving on to step 10:
If we divide 10 by 7, we get 1 and a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 92183.8571
If we take 7 away from 10, we end up 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.

Let's proceed to step 11:
7 can be fit into 30 4 times, resulting in a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 92183.85714
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.

On to step 12:
20 divided by 7 is 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 92183.857142
The remainder is 6 after subtracting 14 from 20.
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 13:
When dividing 60 by 7, we get 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 92183.8571428
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.

On to step 14:
40 divided by 7 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 92183.85714285
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.

After the division, we end up with 92183.85714285 and a remainder of 5e-09.
