We're dividing 66308450 by 396 
We're looking to find how many times 396 goes into 66308450.

Step 1:
6 divided by 396 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 396

Going ahead to step 2:
If we divide 66 by 396, we get 0 and a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Grab the next digit (3) from the dividend, add it to 66, then carry on: 663 / 396

Going ahead to step 3:
The number 396 fits into 663 1 times, leaving a remainder of 267.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 396 from 663 to get 267.
Append the next digit (0) from the dividend to 267 and continue with: 2670 / 396

Step 4:
If we divide 2670 by 396, we get 6 and a remainder of 294.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtracting 2376 from 2670 leaves us with 294.
Bring next digit (8) of the dividend behind the 294 and repeat the process: 2948 / 396

On to step 5:
If we divide 2948 by 396, we get 7 and a remainder of 176.
Record the quotient 7 as the next digit in the result. 
Result so far: 167.0
If we subtract 2772 from 2948, we get 176.
Include the next digit (4) from the dividend after 176, then repeat: 1764 / 396

Step 6:
396 can be fit into 1764 4 times, resulting in a remainder of 180.
Record the quotient 4 as the next digit in the result. 
Result so far: 1674.0
The remainder is 180 after subtracting 1584 from 1764.
Take the next digit (5) from the dividend and append it to 180, then repeat: 1805 / 396

Let's proceed to step 7:
When dividing 1805 by 396, we get 4 with a remainder of 221.
The next digit of our result is 4. 
Result so far: 16744.0
If we subtract 1584 from 1805, we get 221.
Grab the next digit (0) from the dividend, add it to 221, then carry on: 2210 / 396

Step 8:
When dividing 2210 by 396, we get 5 with a remainder of 230.
The number 5 becomes the next digit in our result. 
Result so far: 167445.0
The remainder is 230 after subtracting 1980 from 2210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 9:
396 goes into 2300 5 times with a remainder of 320.
Put 5 as the next digit of the answer. 
Result so far: 167445.5
If we take 1980 away from 2300, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 10:
The number 396 fits into 3200 8 times, leaving a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 167445.58
If we subtract 3168 from 3200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 11:
When dividing 320 by 396, we get 0 with a remainder of 320.
Write down 0 as next digit of the result. 
Result so far: 167445.58
If we take 0 away from 320, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 12:
The number 396 fits into 3200 8 times, leaving a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 167445.5808
If we subtract 3168 from 3200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 13:
If we divide 320 by 396, we get 0 and a remainder of 320.
Write down 0 as next digit of the result. 
Result so far: 167445.5808
Deduct 0 from 320 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 14:
396 can be fit into 3200 8 times, resulting in a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 167445.580808
If we subtract 3168 from 3200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 15:
396 goes into 320 0 times with a remainder of 320.
Use 0 as the next digit of our solution. 
Result so far: 167445.580808
Deduct 0 from 320 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 16:
The number 396 fits into 3200 8 times, leaving a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 167445.58080808
If we subtract 3168 from 3200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 167445.58080808 with a balance of 3.2e-08.
