Let's divide 397721 by 66
Let's see how many times 66 fits into 397721.

Moving on to step 1:
66 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 66

On to step 2:
66 can be fit into 39 0 times, resulting in a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Append the next digit (7) from the dividend to 39 and continue with: 397 / 66

Advancing to step 3:
397 divided by 66 is 6 with a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 396 from 397 to get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 66

Let's proceed to step 4:
66 goes into 17 0 times with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 60.0
Subtract 0 from 17 to get 17.
Include the next digit (2) from the dividend after 17, then repeat: 172 / 66

Going ahead to step 5:
172 divided by 66 is 2 with a remainder of 40.
The next digit of our result is 2. 
Result so far: 602.0
The remainder is 40 after subtracting 132 from 172.
Grab the next digit (1) from the dividend, add it to 40, then carry on: 401 / 66

On to step 6:
66 goes into 401 6 times with a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 6026.0
If we subtract 396 from 401, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
If we divide 50 by 66, we get 0 and a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 6026.0
Subtract 0 from 50 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.

Going ahead to step 8:
66 can be fit into 500 7 times, resulting in a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 6026.07
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.

On to step 9:
380 divided by 66 is 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 6026.075
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.

Going ahead to step 10:
500 divided by 66 is 7 with a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 6026.0757
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.

On to step 11:
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: 6026.07575
Deduct 330 from 380 and we're left 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.

On to step 12:
The number 66 fits into 500 7 times, leaving a remainder of 38.
The next digit of our result is 7. 
Result so far: 6026.075757
Deduct 462 from 500 and we're left 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.

On to 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: 6026.0757575
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 14:
66 goes into 500 7 times with a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 6026.07575757
The remainder is 38 after subtracting 462 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Our division results in 6026.07575757 with a remaining 3.8e-08.
