We're dividing 6233933 by 309 
Let's see how many times 309 fits into 6233933.

Step 1:
If we divide 6 by 309, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 309

Step 2:
The number 309 fits into 62 0 times, leaving a remainder of 62.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 62 and we're left with 62.
Bring next digit (3) of the dividend behind the 62 and repeat the process: 623 / 309

Step 3:
When dividing 623 by 309, we get 2 with a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 618 from 623 leaves us with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 309

Moving on to step 4:
When dividing 53 by 309, we get 0 with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Deduct 0 from 53 and we're left with 53.
Fetch the next digit (9) from the dividend, attach it to 53 and continue: 539 / 309

On to step 5:
539 divided by 309 is 1 with a remainder of 230.
Put 1 as the next digit of the answer. 
Result so far: 201.0
If we subtract 309 from 539, we get 230.
Grab the next digit (3) from the dividend, add it to 230, then carry on: 2303 / 309

Let's proceed to step 6:
309 goes into 2303 7 times with a remainder of 140.
Write down 7 as next digit of the result. 
Result so far: 2017.0
The remainder is 140 after subtracting 2163 from 2303.
Bring next digit (3) of the dividend behind the 140 and repeat the process: 1403 / 309

Going ahead to step 7:
1403 divided by 309 is 4 with a remainder of 167.
The next digit of our result is 4. 
Result so far: 20174.0
If we subtract 1236 from 1403, we get 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Moving on to step 8:
309 goes into 1670 5 times with a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 20174.5
Subtract 1545 from 1670 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Going ahead to step 9:
309 goes into 1250 4 times with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 20174.54
If we subtract 1236 from 1250, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 10:
If we divide 140 by 309, we get 0 and a remainder of 140.
The next digit of our result is 0. 
Result so far: 20174.54
Subtracting 0 from 140 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 11:
309 can be fit into 1400 4 times, resulting in a remainder of 164.
Record the quotient 4 as the next digit in the result. 
Result so far: 20174.5404
Subtracting 1236 from 1400 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Moving on to step 12:
When dividing 1640 by 309, we get 5 with a remainder of 95.
Use 5 as the next digit of our solution. 
Result so far: 20174.54045
Subtracting 1545 from 1640 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 13:
The number 309 fits into 950 3 times, leaving a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 20174.540453
Subtracting 927 from 950 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 14:
When dividing 230 by 309, we get 0 with a remainder of 230.
Put 0 as the next digit of the answer. 
Result so far: 20174.540453
Subtract 0 from 230 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 15:
2300 divided by 309 is 7 with a remainder of 137.
The number 7 becomes the next digit in our result. 
Result so far: 20174.54045307
If we subtract 2163 from 2300, we get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

The final outcome is 20174.54045307, with a leftover of 1.37e-07.
