We're dividing 843178 by 66 
Our goal is to divide 843178 by 66.

Advancing to step 1:
66 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 66

Step 2:
When dividing 84 by 66, we get 1 with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 66 from 84 leaves us with 18.
Bring next digit (3) of the dividend behind the 18 and repeat the process: 183 / 66

Moving on to step 3:
When dividing 183 by 66, we get 2 with a remainder of 51.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 132 from 183 leaves us with 51.
Bring next digit (1) of the dividend behind the 51 and repeat the process: 511 / 66

On to step 4:
When dividing 511 by 66, we get 7 with a remainder of 49.
The next digit of our result is 7. 
Result so far: 127.0
Subtract 462 from 511 to get 49.
Take the next digit (7) from the dividend and append it to 49, then repeat: 497 / 66

Step 5:
66 can be fit into 497 7 times, resulting in a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 1277.0
Subtract 462 from 497 to get 35.
Bring next digit (8) of the dividend behind the 35 and repeat the process: 358 / 66

On to step 6:
66 can be fit into 358 5 times, resulting in a remainder of 28.
Use 5 as the next digit of our solution. 
Result so far: 12775.0
Deduct 330 from 358 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 7:
66 can be fit into 280 4 times, resulting in a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 12775.4
The remainder is 16 after subtracting 264 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
When dividing 160 by 66, we get 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 12775.42
Subtract 132 from 160 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
66 goes into 280 4 times with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 12775.424
Subtract 264 from 280 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
When dividing 160 by 66, we get 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 12775.4242
If we subtract 132 from 160, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 11:
If we divide 280 by 66, we get 4 and a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 12775.42424
If we take 264 away from 280, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 12:
160 divided by 66 is 2 with a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 12775.424242
If we take 132 away from 160, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 13:
If we divide 280 by 66, we get 4 and a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 12775.4242424
If we subtract 264 from 280, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 14:
66 can be fit into 160 2 times, resulting in a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 12775.42424242
If we take 132 away from 160, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

In conclusion, the division gives 12775.42424242 with a balance of 2.8e-08.
