We're dividing 81970630 by 539 
We want to figure out the number of times 81970630 can be divided by 539.

On to step 1:
If we divide 8 by 539, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 539

Step 2:
When dividing 81 by 539, we get 0 with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Bring next digit (9) of the dividend behind the 81 and repeat the process: 819 / 539

Going ahead to step 3:
If we divide 819 by 539, we get 1 and a remainder of 280.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 280 after subtracting 539 from 819.
Bring next digit (7) of the dividend behind the 280 and repeat the process: 2807 / 539

On to step 4:
2807 divided by 539 is 5 with a remainder of 112.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtracting 2695 from 2807 leaves us with 112.
Grab the next digit (0) from the dividend, add it to 112, then carry on: 1120 / 539

Let's proceed to step 5:
539 goes into 1120 2 times with a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 152.0
Deduct 1078 from 1120 and we're left with 42.
Fetch the next digit (6) from the dividend, attach it to 42 and continue: 426 / 539

Step 6:
539 can be fit into 426 0 times, resulting in a remainder of 426.
The number 0 becomes the next digit in our result. 
Result so far: 1520.0
If we take 0 away from 426, we end up with 426.
Append the next digit (3) from the dividend to 426 and continue with: 4263 / 539

On to step 7:
4263 divided by 539 is 7 with a remainder of 490.
Use 7 as the next digit of our solution. 
Result so far: 15207.0
Deduct 3773 from 4263 and we're left with 490.
Bring next digit (0) of the dividend behind the 490 and repeat the process: 4900 / 539

Let's proceed to step 8:
539 goes into 4900 9 times with a remainder of 49.
Record the quotient 9 as the next digit in the result. 
Result so far: 152079.0
The remainder is 49 after subtracting 4851 from 4900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 9:
If we divide 490 by 539, we get 0 and a remainder of 490.
Put 0 as the next digit of the answer. 
Result so far: 152079.0
Deduct 0 from 490 and we're left with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Advancing to step 10:
If we divide 4900 by 539, we get 9 and a remainder of 49.
The number 9 becomes the next digit in our result. 
Result so far: 152079.09
Deduct 4851 from 4900 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 11:
490 divided by 539 is 0 with a remainder of 490.
Write down 0 as next digit of the result. 
Result so far: 152079.09
If we take 0 away from 490, we end up with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Advancing to step 12:
539 goes into 4900 9 times with a remainder of 49.
Write down 9 as next digit of the result. 
Result so far: 152079.0909
If we subtract 4851 from 4900, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 13:
When dividing 490 by 539, we get 0 with a remainder of 490.
The number 0 becomes the next digit in our result. 
Result so far: 152079.0909
Deduct 0 from 490 and we're left with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Going ahead to step 14:
539 can be fit into 4900 9 times, resulting in a remainder of 49.
Record the quotient 9 as the next digit in the result. 
Result so far: 152079.090909
Subtract 4851 from 4900 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 15:
If we divide 490 by 539, we get 0 and a remainder of 490.
Use 0 as the next digit of our solution. 
Result so far: 152079.090909
Deduct 0 from 490 and we're left with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Going ahead to step 16:
539 can be fit into 4900 9 times, resulting in a remainder of 49.
Write down 9 as next digit of the result. 
Result so far: 152079.09090909
If we take 4851 away from 4900, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

After the division, we end up with 152079.09090909 and a remainder of 4.9e-08.
