380412 divided by 66 
We want to figure out the number of times 380412 can be divided by 66.

Step 1:
66 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 66

Let's proceed to step 2:
If we divide 38 by 66, we get 0 and a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 38, we end up with 38.
Fetch the next digit (0) from the dividend, attach it to 38 and continue: 380 / 66

Let's proceed to step 3:
The number 66 fits into 380 5 times, leaving a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 50 after subtracting 330 from 380.
Include the next digit (4) from the dividend after 50, then repeat: 504 / 66

Advancing to step 4:
504 divided by 66 is 7 with a remainder of 42.
The number 7 becomes the next digit in our result. 
Result so far: 57.0
The remainder is 42 after subtracting 462 from 504.
Grab the next digit (1) from the dividend, add it to 42, then carry on: 421 / 66

Moving on to step 5:
66 goes into 421 6 times with a remainder of 25.
The next digit of our result is 6. 
Result so far: 576.0
If we subtract 396 from 421, we get 25.
Grab the next digit (2) from the dividend, add it to 25, then carry on: 252 / 66

Moving on to step 6:
If we divide 252 by 66, we get 3 and a remainder of 54.
The number 3 becomes the next digit in our result. 
Result so far: 5763.0
If we subtract 198 from 252, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 7:
66 can be fit into 540 8 times, resulting in a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 5763.8
If we take 528 away from 540, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
66 goes into 120 1 times with a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 5763.81
Deduct 66 from 120 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 9:
66 goes into 540 8 times with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 5763.818
Deduct 528 from 540 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
120 divided by 66 is 1 with a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 5763.8181
The remainder is 54 after subtracting 66 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 11:
540 divided by 66 is 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 5763.81818
Subtract 528 from 540 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 12:
When dividing 120 by 66, we get 1 with a remainder of 54.
The next digit of our result is 1. 
Result so far: 5763.818181
The remainder is 54 after subtracting 66 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 13:
If we divide 540 by 66, we get 8 and a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 5763.8181818
Subtract 528 from 540 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 14:
When dividing 120 by 66, we get 1 with a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 5763.81818181
Subtract 66 from 120 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

After the division, we end up with 5763.81818181 and a remainder of 5.4e-08.
