We look at the division of 664420 by 70 
We want to divide 664420 by 70.

Moving on to step 1:
If we divide 6 by 70, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 70

Going ahead to step 2:
If we divide 66 by 70, we get 0 and a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Take the next digit (4) from the dividend and append it to 66, then repeat: 664 / 70

Step 3:
70 can be fit into 664 9 times, resulting in a remainder of 34.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 630 from 664, we get 34.
Include the next digit (4) from the dividend after 34, then repeat: 344 / 70

Let's proceed to step 4:
When dividing 344 by 70, we get 4 with a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 94.0
Subtract 280 from 344 to get 64.
Append the next digit (2) from the dividend to 64 and continue with: 642 / 70

On to step 5:
If we divide 642 by 70, we get 9 and a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 949.0
Subtracting 630 from 642 leaves us with 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 70

Step 6:
70 can be fit into 120 1 times, resulting in a remainder of 50.
Write down 1 as next digit of the result. 
Result so far: 9491.0
If we subtract 70 from 120, 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.

Advancing to step 7:
The number 70 fits into 500 7 times, leaving a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 9491.7
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.

Advancing to step 8:
70 goes into 100 1 times with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 9491.71
If we subtract 70 from 100, we 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.

On to step 9:
When dividing 300 by 70, we get 4 with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 9491.714
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.

Step 10:
If we divide 200 by 70, we get 2 and a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 9491.7142
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.

Moving on to step 11:
If we divide 600 by 70, we get 8 and a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 9491.71428
Subtract 560 from 600 to 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.

Advancing to step 12:
70 can be fit into 400 5 times, resulting in a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 9491.714285
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 13:
The number 70 fits into 500 7 times, leaving a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 9491.7142857
The remainder is 10 after subtracting 490 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 14:
When dividing 100 by 70, we get 1 with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 9491.71428571
The remainder is 30 after subtracting 70 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 9491.71428571 and a remainder of 3e-08.
