397886 divided by 66 
We're looking to find how many times 66 goes into 397886.

On to step 1:
The number 66 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 66

On to step 2:
39 divided by 66 is 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Include the next digit (7) from the dividend after 39, then repeat: 397 / 66

Going ahead to step 3:
When dividing 397 by 66, we get 6 with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 1 after subtracting 396 from 397.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 66

Moving on to step 4:
18 divided by 66 is 0 with a remainder of 18.
The next digit of our result is 0. 
Result so far: 60.0
Subtract 0 from 18 to get 18.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 66

On to step 5:
188 divided by 66 is 2 with a remainder of 56.
The number 2 becomes the next digit in our result. 
Result so far: 602.0
Subtract 132 from 188 to get 56.
Grab the next digit (6) from the dividend, add it to 56, then carry on: 566 / 66

Moving on to step 6:
66 goes into 566 8 times with a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 6028.0
Subtracting 528 from 566 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 7:
When dividing 380 by 66, we get 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 6028.5
The remainder is 50 after subtracting 330 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
500 divided by 66 is 7 with a remainder of 38.
The next digit of our result is 7. 
Result so far: 6028.57
If we subtract 462 from 500, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 9:
66 can be fit into 380 5 times, resulting in a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 6028.575
Subtract 330 from 380 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
If we divide 500 by 66, we get 7 and a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 6028.5757
If we take 462 away from 500, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 11:
If we divide 380 by 66, we get 5 and a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 6028.57575
Subtracting 330 from 380 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 12:
If we divide 500 by 66, we get 7 and a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 6028.575757
Subtract 462 from 500 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 13:
When dividing 380 by 66, we get 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 6028.5757575
If we subtract 330 from 380, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 14:
66 can be fit into 500 7 times, resulting in a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 6028.57575757
Subtract 462 from 500 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

After the division, we end up with 6028.57575757 and a remainder of 3.8e-08.
