We're dividing 83593437 by 309 
We want to figure out the number of times 83593437 can be divided by 309.

Moving on to step 1:
The number 309 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 309

Moving on to step 2:
309 goes into 83 0 times with a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Include the next digit (5) from the dividend after 83, then repeat: 835 / 309

Step 3:
The number 309 fits into 835 2 times, leaving a remainder of 217.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 618 from 835 to get 217.
Grab the next digit (9) from the dividend, add it to 217, then carry on: 2179 / 309

Going ahead to step 4:
The number 309 fits into 2179 7 times, leaving a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 27.0
The remainder is 16 after subtracting 2163 from 2179.
Append the next digit (3) from the dividend to 16 and continue with: 163 / 309

On to step 5:
163 divided by 309 is 0 with a remainder of 163.
Use 0 as the next digit of our solution. 
Result so far: 270.0
Subtracting 0 from 163 leaves us with 163.
Include the next digit (4) from the dividend after 163, then repeat: 1634 / 309

Step 6:
309 goes into 1634 5 times with a remainder of 89.
The number 5 becomes the next digit in our result. 
Result so far: 2705.0
Subtract 1545 from 1634 to get 89.
Append the next digit (3) from the dividend to 89 and continue with: 893 / 309

On to step 7:
309 goes into 893 2 times with a remainder of 275.
Put 2 as the next digit of the answer. 
Result so far: 27052.0
Subtract 618 from 893 to get 275.
Include the next digit (7) from the dividend after 275, then repeat: 2757 / 309

Going ahead to step 8:
When dividing 2757 by 309, we get 8 with a remainder of 285.
The number 8 becomes the next digit in our result. 
Result so far: 270528.0
Subtract 2472 from 2757 to get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Let's proceed to step 9:
If we divide 2850 by 309, we get 9 and a remainder of 69.
Record the quotient 9 as the next digit in the result. 
Result so far: 270528.9
Deduct 2781 from 2850 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 10:
309 goes into 690 2 times with a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 270528.92
The remainder is 72 after subtracting 618 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 11:
720 divided by 309 is 2 with a remainder of 102.
Put 2 as the next digit of the answer. 
Result so far: 270528.922
If we subtract 618 from 720, we get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

In conclusion, the division gives 270528.922 with a balance of 0.0102.
