We're dividing 43439304 by 660 
Our goal is to divide 43439304 by 660.

Moving on to step 1:
660 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 660

Moving on to step 2:
660 can be fit into 43 0 times, resulting in a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Include the next digit (4) from the dividend after 43, then repeat: 434 / 660

Going ahead to step 3:
The number 660 fits into 434 0 times, leaving a remainder of 434.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 434, we get 434.
Grab the next digit (3) from the dividend, add it to 434, then carry on: 4343 / 660

Step 4:
4343 divided by 660 is 6 with a remainder of 383.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 3960 from 4343 to get 383.
Include the next digit (9) from the dividend after 383, then repeat: 3839 / 660

Advancing to step 5:
660 can be fit into 3839 5 times, resulting in a remainder of 539.
Write down 5 as next digit of the result. 
Result so far: 65.0
Subtracting 3300 from 3839 leaves us with 539.
Append the next digit (3) from the dividend to 539 and continue with: 5393 / 660

On to step 6:
When dividing 5393 by 660, we get 8 with a remainder of 113.
Use 8 as the next digit of our solution. 
Result so far: 658.0
If we subtract 5280 from 5393, we get 113.
Bring next digit (0) of the dividend behind the 113 and repeat the process: 1130 / 660

Step 7:
When dividing 1130 by 660, we get 1 with a remainder of 470.
The number 1 becomes the next digit in our result. 
Result so far: 6581.0
The remainder is 470 after subtracting 660 from 1130.
Grab the next digit (4) from the dividend, add it to 470, then carry on: 4704 / 660

Going ahead to step 8:
4704 divided by 660 is 7 with a remainder of 84.
Record the quotient 7 as the next digit in the result. 
Result so far: 65817.0
Subtract 4620 from 4704 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 9:
840 divided by 660 is 1 with a remainder of 180.
The number 1 becomes the next digit in our result. 
Result so far: 65817.1
If we take 660 away from 840, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 10:
If we divide 1800 by 660, we get 2 and a remainder of 480.
Record the quotient 2 as the next digit in the result. 
Result so far: 65817.12
Subtracting 1320 from 1800 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 11:
660 goes into 4800 7 times with a remainder of 180.
Put 7 as the next digit of the answer. 
Result so far: 65817.127
If we take 4620 away from 4800, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 12:
If we divide 1800 by 660, we get 2 and a remainder of 480.
The next digit of our result is 2. 
Result so far: 65817.1272
Deduct 1320 from 1800 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 13:
The number 660 fits into 4800 7 times, leaving a remainder of 180.
The number 7 becomes the next digit in our result. 
Result so far: 65817.12727
The remainder is 180 after subtracting 4620 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 14:
660 can be fit into 1800 2 times, resulting in a remainder of 480.
Put 2 as the next digit of the answer. 
Result so far: 65817.127272
Subtracting 1320 from 1800 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 15:
660 can be fit into 4800 7 times, resulting in a remainder of 180.
Use 7 as the next digit of our solution. 
Result so far: 65817.1272727
Subtract 4620 from 4800 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 16:
1800 divided by 660 is 2 with a remainder of 480.
Put 2 as the next digit of the answer. 
Result so far: 65817.12727272
Deduct 1320 from 1800 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

In conclusion, the division gives 65817.12727272 with a balance of 4.8e-07.
