We divide 39666 by 70
Our goal is to divide 39666 by 70.

Moving on to step 1:
3 divided by 70 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 70

Moving on to step 2:
The number 70 fits into 39 0 times, leaving a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Bring next digit (6) of the dividend behind the 39 and repeat the process: 396 / 70

Let's proceed to step 3:
396 divided by 70 is 5 with a remainder of 46.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 350 away from 396, we end up with 46.
Include the next digit (6) from the dividend after 46, then repeat: 466 / 70

Let's proceed to step 4:
70 goes into 466 6 times with a remainder of 46.
The number 6 becomes the next digit in our result. 
Result so far: 56.0
If we subtract 420 from 466, we get 46.
Fetch the next digit (6) from the dividend, attach it to 46 and continue: 466 / 70

On to step 5:
If we divide 466 by 70, we get 6 and a remainder of 46.
Use 6 as the next digit of our solution. 
Result so far: 566.0
Subtract 420 from 466 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 6:
If we divide 460 by 70, we get 6 and a remainder of 40.
The next digit of our result is 6. 
Result so far: 566.6
Deduct 420 from 460 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 7:
The number 70 fits into 400 5 times, leaving a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 566.65
If we take 350 away from 400, 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 8:
When dividing 500 by 70, we get 7 with a remainder of 10.
The next digit of our result is 7. 
Result so far: 566.657
Deduct 490 from 500 and we're left 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.

Advancing to step 9:
The number 70 fits into 100 1 times, leaving a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 566.6571
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.

Step 10:
When dividing 300 by 70, we get 4 with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 566.65714
Deduct 280 from 300 and we're left 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.

Moving on to step 11:
The number 70 fits into 200 2 times, leaving a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 566.657142
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.

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: 566.6571428
Deduct 560 from 600 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 13:
70 can be fit into 400 5 times, resulting in a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 566.65714285
Deduct 350 from 400 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.

In conclusion, the division gives 566.65714285 with a balance of 5e-08.
