We're dividing 664109 by 70 
We're looking to find how many times 70 goes into 664109.

Let's proceed to step 1:
70 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 70

Going ahead to step 2:
70 goes into 66 0 times with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Bring next digit (4) of the dividend behind the 66 and repeat the process: 664 / 70

Moving on to step 3:
70 goes into 664 9 times with a remainder of 34.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 630 from 664 leaves us with 34.
Append the next digit (1) from the dividend to 34 and continue with: 341 / 70

Let's proceed to step 4:
When dividing 341 by 70, we get 4 with a remainder of 61.
The number 4 becomes the next digit in our result. 
Result so far: 94.0
If we take 280 away from 341, we end up with 61.
Take the next digit (0) from the dividend and append it to 61, then repeat: 610 / 70

Moving on to step 5:
When dividing 610 by 70, we get 8 with a remainder of 50.
The next digit of our result is 8. 
Result so far: 948.0
Subtract 560 from 610 to get 50.
Fetch the next digit (9) from the dividend, attach it to 50 and continue: 509 / 70

Going ahead to step 6:
70 goes into 509 7 times with a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 9487.0
Subtracting 490 from 509 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
70 can be fit into 190 2 times, resulting in a remainder of 50.
The number 2 becomes the next digit in our result. 
Result so far: 9487.2
Deduct 140 from 190 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
500 divided by 70 is 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 9487.27
Subtracting 490 from 500 leaves us with 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 9:
70 goes into 100 1 times with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 9487.271
Subtract 70 from 100 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
300 divided by 70 is 4 with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 9487.2714
If we take 280 away from 300, we end up 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 11:
The number 70 fits into 200 2 times, leaving a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 9487.27142
Deduct 140 from 200 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 12:
If we divide 600 by 70, we get 8 and a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 9487.271428
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.

Moving on to step 13:
70 can be fit into 400 5 times, resulting in a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 9487.2714285
If we subtract 350 from 400, we 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 14:
If we divide 500 by 70, we get 7 and a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 9487.27142857
Subtracting 490 from 500 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 9487.27142857, with a leftover of 1e-08.
