8213033 ÷ 660 
Let's see how many times 660 fits into 8213033.

Step 1:
When dividing 8 by 660, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 660

Step 2:
660 goes into 82 0 times with a remainder of 82.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 82, we get 82.
Bring next digit (1) of the dividend behind the 82 and repeat the process: 821 / 660

Let's proceed to step 3:
The number 660 fits into 821 1 times, leaving a remainder of 161.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 660 from 821 to get 161.
Fetch the next digit (3) from the dividend, attach it to 161 and continue: 1613 / 660

Going ahead to step 4:
660 goes into 1613 2 times with a remainder of 293.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 1320 away from 1613, we end up with 293.
Grab the next digit (0) from the dividend, add it to 293, then carry on: 2930 / 660

Step 5:
660 can be fit into 2930 4 times, resulting in a remainder of 290.
Use 4 as the next digit of our solution. 
Result so far: 124.0
Subtract 2640 from 2930 to get 290.
Include the next digit (3) from the dividend after 290, then repeat: 2903 / 660

Going ahead to step 6:
2903 divided by 660 is 4 with a remainder of 263.
Record the quotient 4 as the next digit in the result. 
Result so far: 1244.0
The remainder is 263 after subtracting 2640 from 2903.
Take the next digit (3) from the dividend and append it to 263, then repeat: 2633 / 660

Moving on to step 7:
660 can be fit into 2633 3 times, resulting in a remainder of 653.
The next digit of our result is 3. 
Result so far: 12443.0
If we subtract 1980 from 2633, we get 653.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6530, and continue the process.

On to step 8:
660 goes into 6530 9 times with a remainder of 590.
Put 9 as the next digit of the answer. 
Result so far: 12443.9
If we subtract 5940 from 6530, we get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Moving on to step 9:
660 can be fit into 5900 8 times, resulting in a remainder of 620.
Put 8 as the next digit of the answer. 
Result so far: 12443.98
Subtract 5280 from 5900 to get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Step 10:
660 goes into 6200 9 times with a remainder of 260.
Use 9 as the next digit of our solution. 
Result so far: 12443.989
Subtracting 5940 from 6200 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 11:
The number 660 fits into 2600 3 times, leaving a remainder of 620.
Record the quotient 3 as the next digit in the result. 
Result so far: 12443.9893
If we subtract 1980 from 2600, we get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Going ahead to step 12:
The number 660 fits into 6200 9 times, leaving a remainder of 260.
Use 9 as the next digit of our solution. 
Result so far: 12443.98939
If we take 5940 away from 6200, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 13:
The number 660 fits into 2600 3 times, leaving a remainder of 620.
Record the quotient 3 as the next digit in the result. 
Result so far: 12443.989393
If we take 1980 away from 2600, we end up with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Step 14:
The number 660 fits into 6200 9 times, leaving a remainder of 260.
Record the quotient 9 as the next digit in the result. 
Result so far: 12443.9893939
The remainder is 260 after subtracting 5940 from 6200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 15:
If we divide 2600 by 660, we get 3 and a remainder of 620.
The number 3 becomes the next digit in our result. 
Result so far: 12443.98939393
If we subtract 1980 from 2600, we get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

In conclusion, the division gives 12443.98939393 with a balance of 6.2e-07.
