380321 ÷ 66 
We want to figure out the number of times 380321 can be divided by 66.

Step 1:
The number 66 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 66

Step 2:
38 divided by 66 is 0 with a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Take the next digit (0) from the dividend and append it to 38, then repeat: 380 / 66

Let's proceed to step 3:
380 divided by 66 is 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 330 from 380, we get 50.
Fetch the next digit (3) from the dividend, attach it to 50 and continue: 503 / 66

Let's proceed to step 4:
66 can be fit into 503 7 times, resulting in a remainder of 41.
The number 7 becomes the next digit in our result. 
Result so far: 57.0
Subtracting 462 from 503 leaves us with 41.
Grab the next digit (2) from the dividend, add it to 41, then carry on: 412 / 66

On to step 5:
The number 66 fits into 412 6 times, leaving a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 576.0
Subtract 396 from 412 to get 16.
Bring next digit (1) of the dividend behind the 16 and repeat the process: 161 / 66

Step 6:
66 can be fit into 161 2 times, resulting in a remainder of 29.
Record the quotient 2 as the next digit in the result. 
Result so far: 5762.0
Subtract 132 from 161 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 7:
The number 66 fits into 290 4 times, leaving a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 5762.4
The remainder is 26 after subtracting 264 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 8:
If we divide 260 by 66, we get 3 and a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 5762.43
Subtracting 198 from 260 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 9:
620 divided by 66 is 9 with a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 5762.439
If we subtract 594 from 620, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 10:
When dividing 260 by 66, we get 3 with a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 5762.4393
Deduct 198 from 260 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 11:
66 goes into 620 9 times with a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 5762.43939
Subtract 594 from 620 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 12:
66 can be fit into 260 3 times, resulting in a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 5762.439393
If we take 198 away from 260, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 13:
If we divide 620 by 66, we get 9 and a remainder of 26.
The next digit of our result is 9. 
Result so far: 5762.4393939
Subtract 594 from 620 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 14:
66 can be fit into 260 3 times, resulting in a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 5762.43939393
Subtracting 198 from 260 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The final outcome is 5762.43939393, with a leftover of 6.2e-08.
