We're dividing 539643 by 70 
We want to figure out the number of times 539643 can be divided by 70.

Going ahead to step 1:
70 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 70

Let's proceed to step 2:
70 can be fit into 53 0 times, resulting in a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Grab the next digit (9) from the dividend, add it to 53, then carry on: 539 / 70

On to step 3:
70 goes into 539 7 times with a remainder of 49.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 490 from 539 to get 49.
Fetch the next digit (6) from the dividend, attach it to 49 and continue: 496 / 70

Let's proceed to step 4:
496 divided by 70 is 7 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 (4) from the dividend after 6, then repeat: 64 / 70

On to step 5:
When dividing 64 by 70, we get 0 with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 770.0
Subtracting 0 from 64 leaves us with 64.
Bring next digit (3) of the dividend behind the 64 and repeat the process: 643 / 70

Advancing to step 6:
When dividing 643 by 70, we get 9 with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 7709.0
Subtract 630 from 643 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
70 goes into 130 1 times with a remainder of 60.
The number 1 becomes the next digit in our result. 
Result so far: 7709.1
Subtract 70 from 130 to 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 8:
When dividing 600 by 70, we get 8 with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 7709.18
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.

Step 9:
70 can be fit into 400 5 times, resulting in a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 7709.185
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 10:
The number 70 fits into 500 7 times, leaving a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 7709.1857
If we subtract 490 from 500, we 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.

Let's proceed to step 11:
70 can be fit into 100 1 times, resulting in a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 7709.18571
Deduct 70 from 100 and we're left 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.

On to step 12:
70 goes into 300 4 times with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 7709.185714
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 13:
200 divided by 70 is 2 with a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 7709.1857142
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.

Step 14:
The number 70 fits into 600 8 times, leaving a remainder of 40.
The next digit of our result is 8. 
Result so far: 7709.18571428
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.

After the division, we end up with 7709.18571428 and a remainder of 4e-08.
