We look at the division of 312413 by 66 
Our goal is to divide 312413 by 66.

Let's proceed to step 1:
The number 66 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 66

Step 2:
66 can be fit into 31 0 times, resulting in a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Bring next digit (2) of the dividend behind the 31 and repeat the process: 312 / 66

Step 3:
The number 66 fits into 312 4 times, leaving a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 264 from 312, we get 48.
Include the next digit (4) from the dividend after 48, then repeat: 484 / 66

On to step 4:
66 goes into 484 7 times with a remainder of 22.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
If we take 462 away from 484, we end up with 22.
Append the next digit (1) from the dividend to 22 and continue with: 221 / 66

On to step 5:
66 goes into 221 3 times with a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 473.0
Deduct 198 from 221 and we're left with 23.
Fetch the next digit (3) from the dividend, attach it to 23 and continue: 233 / 66

On to step 6:
The number 66 fits into 233 3 times, leaving a remainder of 35.
Use 3 as the next digit of our solution. 
Result so far: 4733.0
The remainder is 35 after subtracting 198 from 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 7:
66 can be fit into 350 5 times, resulting in a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 4733.5
If we subtract 330 from 350, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
When dividing 200 by 66, we get 3 with a remainder of 2.
The next digit of our result is 3. 
Result so far: 4733.53
Subtract 198 from 200 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
20 divided by 66 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 4733.53
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
When dividing 200 by 66, we get 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 4733.5303
If we subtract 198 from 200, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 11:
The number 66 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 4733.5303
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
200 divided by 66 is 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 4733.530303
Subtracting 198 from 200 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 13:
If we divide 20 by 66, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 4733.530303
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 14:
When dividing 200 by 66, we get 3 with a remainder of 2.
The next digit of our result is 3. 
Result so far: 4733.53030303
Subtracting 198 from 200 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 4733.53030303 with a balance of 2e-09.
