We're dividing 43339573 by 311 
Our goal is to divide 43339573 by 311.

Step 1:
311 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 311

Going ahead to step 2:
When dividing 43 by 311, we get 0 with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Include the next digit (3) from the dividend after 43, then repeat: 433 / 311

Advancing to step 3:
311 goes into 433 1 times with a remainder of 122.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 311 from 433, we get 122.
Take the next digit (3) from the dividend and append it to 122, then repeat: 1223 / 311

Step 4:
1223 divided by 311 is 3 with a remainder of 290.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we take 933 away from 1223, we end up with 290.
Bring next digit (9) of the dividend behind the 290 and repeat the process: 2909 / 311

Advancing to step 5:
The number 311 fits into 2909 9 times, leaving a remainder of 110.
The next digit of our result is 9. 
Result so far: 139.0
If we take 2799 away from 2909, we end up with 110.
Take the next digit (5) from the dividend and append it to 110, then repeat: 1105 / 311

Advancing to step 6:
When dividing 1105 by 311, we get 3 with a remainder of 172.
The next digit of our result is 3. 
Result so far: 1393.0
If we take 933 away from 1105, we end up with 172.
Fetch the next digit (7) from the dividend, attach it to 172 and continue: 1727 / 311

Moving on to step 7:
If we divide 1727 by 311, we get 5 and a remainder of 172.
Use 5 as the next digit of our solution. 
Result so far: 13935.0
Subtract 1555 from 1727 to get 172.
Include the next digit (3) from the dividend after 172, then repeat: 1723 / 311

Step 8:
1723 divided by 311 is 5 with a remainder of 168.
Use 5 as the next digit of our solution. 
Result so far: 139355.0
Subtract 1555 from 1723 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Going ahead to step 9:
311 goes into 1680 5 times with a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 139355.5
If we take 1555 away from 1680, we end up with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 10:
311 goes into 1250 4 times with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 139355.54
Deduct 1244 from 1250 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 11:
If we divide 60 by 311, we get 0 and a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 139355.54
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 12:
311 goes into 600 1 times with a remainder of 289.
The number 1 becomes the next digit in our result. 
Result so far: 139355.5401
The remainder is 289 after subtracting 311 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Going ahead to step 13:
311 goes into 2890 9 times with a remainder of 91.
Record the quotient 9 as the next digit in the result. 
Result so far: 139355.54019
Subtract 2799 from 2890 to get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Step 14:
When dividing 910 by 311, we get 2 with a remainder of 288.
The number 2 becomes the next digit in our result. 
Result so far: 139355.540192
If we take 622 away from 910, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Going ahead to step 15:
311 goes into 2880 9 times with a remainder of 81.
The next digit of our result is 9. 
Result so far: 139355.5401929
The remainder is 81 after subtracting 2799 from 2880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

On to step 16:
311 can be fit into 810 2 times, resulting in a remainder of 188.
Write down 2 as next digit of the result. 
Result so far: 139355.54019292
Subtract 622 from 810 to get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

The final result is 139355.54019292 with a remainder of 1.88e-07.
