We look at the division of 640307 by 70 
We want to divide 640307 by 70.

Moving on to step 1:
When dividing 6 by 70, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 70

On to step 2:
64 divided by 70 is 0 with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Include the next digit (0) from the dividend after 64, then repeat: 640 / 70

Going ahead to step 3:
640 divided by 70 is 9 with a remainder of 10.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 630 from 640, we get 10.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 70

Advancing to step 4:
If we divide 103 by 70, we get 1 and a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 91.0
Deduct 70 from 103 and we're left with 33.
Bring next digit (0) of the dividend behind the 33 and repeat the process: 330 / 70

On to step 5:
When dividing 330 by 70, we get 4 with a remainder of 50.
Use 4 as the next digit of our solution. 
Result so far: 914.0
If we take 280 away from 330, we end up with 50.
Take the next digit (7) from the dividend and append it to 50, then repeat: 507 / 70

On to step 6:
70 can be fit into 507 7 times, resulting in a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 9147.0
The remainder is 17 after subtracting 490 from 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
70 can be fit into 170 2 times, resulting in a remainder of 30.
Record the quotient 2 as the next digit in the result. 
Result so far: 9147.2
Subtracting 140 from 170 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
300 divided by 70 is 4 with a remainder of 20.
The next digit of our result is 4. 
Result so far: 9147.24
Subtracting 280 from 300 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
200 divided by 70 is 2 with a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 9147.242
If we subtract 140 from 200, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 10:
70 goes into 600 8 times with a remainder of 40.
The next digit of our result is 8. 
Result so far: 9147.2428
If we subtract 560 from 600, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
When dividing 400 by 70, we get 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 9147.24285
Subtract 350 from 400 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 12:
70 goes into 500 7 times with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 9147.242857
Subtract 490 from 500 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 13:
70 can be fit into 100 1 times, resulting in a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 9147.2428571
If we take 70 away from 100, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 14:
70 goes into 300 4 times with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 9147.24285714
Subtracting 280 from 300 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 9147.24285714 and a remainder of 2e-08.
