We're dividing 539666 by 70 
We want to figure out the number of times 539666 can be divided by 70.

Going ahead to step 1:
When dividing 5 by 70, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 70

Let's proceed to step 2:
70 goes into 53 0 times with a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Bring next digit (9) of the dividend behind the 53 and repeat the process: 539 / 70

Step 3:
When dividing 539 by 70, we get 7 with a remainder of 49.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 490 away from 539, we end up with 49.
Fetch the next digit (6) from the dividend, attach it to 49 and continue: 496 / 70

Let's proceed to step 4:
70 goes into 496 7 times with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 77.0
The remainder is 6 after subtracting 490 from 496.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 70

Step 5:
If we divide 66 by 70, we get 0 and a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 770.0
Deduct 0 from 66 and we're left with 66.
Bring next digit (6) of the dividend behind the 66 and repeat the process: 666 / 70

Going ahead to step 6:
70 can be fit into 666 9 times, resulting in a remainder of 36.
Write down 9 as next digit of the result. 
Result so far: 7709.0
Deduct 630 from 666 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 7:
70 goes into 360 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 7709.5
Subtracting 350 from 360 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.

Advancing to step 8:
100 divided by 70 is 1 with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 7709.51
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.

Step 9:
If we divide 300 by 70, we get 4 and a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 7709.514
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.

Step 10:
200 divided by 70 is 2 with a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 7709.5142
The remainder is 60 after subtracting 140 from 200.
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 11:
600 divided by 70 is 8 with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 7709.51428
Subtracting 560 from 600 leaves us 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 12:
70 goes into 400 5 times with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 7709.514285
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.

On to step 13:
500 divided by 70 is 7 with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 7709.5142857
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.

Advancing to step 14:
If we divide 100 by 70, we get 1 and a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 7709.51428571
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.

The final result is 7709.51428571 with a remainder of 3e-08.
