We're dividing 66407 by 70 
Our goal is to divide 66407 by 70.

Step 1:
When dividing 6 by 70, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 70

Let's proceed to step 2:
70 goes into 66 0 times with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 66, we get 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.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 34 after subtracting 630 from 664.
Grab the next digit (0) from the dividend, add it to 34, then carry on: 340 / 70

On to step 4:
The number 70 fits into 340 4 times, leaving a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 94.0
If we take 280 away from 340, we end up with 60.
Include the next digit (7) from the dividend after 60, then repeat: 607 / 70

Step 5:
607 divided by 70 is 8 with a remainder of 47.
Record the quotient 8 as the next digit in the result. 
Result so far: 948.0
Subtract 560 from 607 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 6:
70 goes into 470 6 times with a remainder of 50.
Put 6 as the next digit of the answer. 
Result so far: 948.6
If we take 420 away from 470, we end up 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.

On to step 7:
When dividing 500 by 70, we get 7 with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 948.67
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.

Step 8:
70 can be fit into 100 1 times, resulting in a remainder of 30.
The next digit of our result is 1. 
Result so far: 948.671
Subtracting 70 from 100 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.

Going ahead to step 9:
300 divided by 70 is 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 948.6714
Subtract 280 from 300 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
200 divided by 70 is 2 with a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 948.67142
If we take 140 away from 200, we end up 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.

Let's proceed to step 11:
600 divided by 70 is 8 with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 948.671428
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.

On to step 12:
The number 70 fits into 400 5 times, leaving a remainder of 50.
The next digit of our result is 5. 
Result so far: 948.6714285
The remainder is 50 after subtracting 350 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 13:
The number 70 fits into 500 7 times, leaving a remainder of 10.
The next digit of our result is 7. 
Result so far: 948.67142857
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.

Our division results in 948.67142857 with a remaining 1e-08.
