We're dividing 645235 by 7 
We're looking to find how many times 7 goes into 645235.

Advancing to step 1:
The number 7 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 7

On to step 2:
7 goes into 64 9 times with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 63 from 64 and we're left with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 7

Moving on to step 3:
7 goes into 15 2 times with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 92.0
Deduct 14 from 15 and we're left with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 7

Moving on to step 4:
7 can be fit into 12 1 times, resulting in a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 921.0
Subtract 7 from 12 to get 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 7

Moving on to step 5:
53 divided by 7 is 7 with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 9217.0
Deduct 49 from 53 and we're left with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 7

On to step 6:
45 divided by 7 is 6 with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 92176.0
Deduct 42 from 45 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 7:
The number 7 fits into 30 4 times, leaving a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 92176.4
If we subtract 28 from 30, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
7 goes into 20 2 times with a remainder of 6.
The next digit of our result is 2. 
Result so far: 92176.42
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.

Advancing to step 9:
60 divided by 7 is 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 92176.428
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.

Advancing to step 10:
7 goes into 40 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 92176.4285
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 11:
7 goes into 50 7 times with a remainder of 1.
The next digit of our result is 7. 
Result so far: 92176.42857
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.

Advancing to 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: 92176.428571
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.

Let's proceed to step 13:
7 can be fit into 30 4 times, resulting in a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 92176.4285714
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.

On to step 14:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 92176.42857142
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.

In conclusion, the division gives 92176.42857142 with a balance of 6e-09.
