We look at the division of 83489243 by 306 
We're looking to find how many times 306 goes into 83489243.

Moving on to step 1:
306 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 306

Going ahead to step 2:
The number 306 fits into 83 0 times, leaving a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Take the next digit (4) from the dividend and append it to 83, then repeat: 834 / 306

Advancing to step 3:
When dividing 834 by 306, we get 2 with a remainder of 222.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 222 after subtracting 612 from 834.
Grab the next digit (8) from the dividend, add it to 222, then carry on: 2228 / 306

On to step 4:
If we divide 2228 by 306, we get 7 and a remainder of 86.
Put 7 as the next digit of the answer. 
Result so far: 27.0
The remainder is 86 after subtracting 2142 from 2228.
Include the next digit (9) from the dividend after 86, then repeat: 869 / 306

Step 5:
If we divide 869 by 306, we get 2 and a remainder of 257.
Put 2 as the next digit of the answer. 
Result so far: 272.0
Deduct 612 from 869 and we're left with 257.
Bring next digit (2) of the dividend behind the 257 and repeat the process: 2572 / 306

Let's proceed to step 6:
The number 306 fits into 2572 8 times, leaving a remainder of 124.
The next digit of our result is 8. 
Result so far: 2728.0
If we subtract 2448 from 2572, we get 124.
Grab the next digit (4) from the dividend, add it to 124, then carry on: 1244 / 306

Going ahead to step 7:
When dividing 1244 by 306, we get 4 with a remainder of 20.
The next digit of our result is 4. 
Result so far: 27284.0
If we take 1224 away from 1244, we end up with 20.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 306

Advancing to step 8:
306 goes into 203 0 times with a remainder of 203.
Record the quotient 0 as the next digit in the result. 
Result so far: 272840.0
If we take 0 away from 203, we end up with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Let's proceed to step 9:
The number 306 fits into 2030 6 times, leaving a remainder of 194.
Use 6 as the next digit of our solution. 
Result so far: 272840.6
If we subtract 1836 from 2030, we get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Going ahead to step 10:
306 can be fit into 1940 6 times, resulting in a remainder of 104.
Use 6 as the next digit of our solution. 
Result so far: 272840.66
Deduct 1836 from 1940 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

The final outcome is 272840.66, with a leftover of 0.104.
