Let's divide 83308420 by 509
We want to divide 83308420 by 509.

Moving on to step 1:
When dividing 8 by 509, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 509

Step 2:
83 divided by 509 is 0 with a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 83, we end up with 83.
Grab the next digit (3) from the dividend, add it to 83, then carry on: 833 / 509

Moving on to step 3:
The number 509 fits into 833 1 times, leaving a remainder of 324.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 509 from 833 to get 324.
Bring next digit (0) of the dividend behind the 324 and repeat the process: 3240 / 509

Going ahead to step 4:
509 can be fit into 3240 6 times, resulting in a remainder of 186.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we take 3054 away from 3240, we end up with 186.
Include the next digit (8) from the dividend after 186, then repeat: 1868 / 509

Going ahead to step 5:
509 goes into 1868 3 times with a remainder of 341.
The next digit of our result is 3. 
Result so far: 163.0
Subtracting 1527 from 1868 leaves us with 341.
Include the next digit (4) from the dividend after 341, then repeat: 3414 / 509

Step 6:
If we divide 3414 by 509, we get 6 and a remainder of 360.
Put 6 as the next digit of the answer. 
Result so far: 1636.0
The remainder is 360 after subtracting 3054 from 3414.
Include the next digit (2) from the dividend after 360, then repeat: 3602 / 509

Advancing to step 7:
509 can be fit into 3602 7 times, resulting in a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 16367.0
Deduct 3563 from 3602 and we're left with 39.
Include the next digit (0) from the dividend after 39, then repeat: 390 / 509

Going ahead to step 8:
509 can be fit into 390 0 times, resulting in a remainder of 390.
The number 0 becomes the next digit in our result. 
Result so far: 163670.0
The remainder is 390 after subtracting 0 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

On to step 9:
If we divide 3900 by 509, we get 7 and a remainder of 337.
The next digit of our result is 7. 
Result so far: 163670.7
If we subtract 3563 from 3900, we get 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Moving on to step 10:
When dividing 3370 by 509, we get 6 with a remainder of 316.
The number 6 becomes the next digit in our result. 
Result so far: 163670.76
Subtract 3054 from 3370 to get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Step 11:
If we divide 3160 by 509, we get 6 and a remainder of 106.
Put 6 as the next digit of the answer. 
Result so far: 163670.766
If we take 3054 away from 3160, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

The quotient of the division is 163670.766, and the remainder is 0.0106.
