Let's divide 397209 by 66
Let's see how many times 66 fits into 397209.

Advancing to step 1:
66 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (9) from the dividend to 3 and continue with: 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.
Fetch the next digit (7) from the dividend, attach it to 39 and continue: 397 / 66

Step 3:
397 divided by 66 is 6 with a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 396 from 397 and we're left with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 66

Moving on to step 4:
When dividing 12 by 66, we get 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 60.0
Subtracting 0 from 12 leaves us with 12.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 66

Going ahead to step 5:
The number 66 fits into 120 1 times, leaving a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 601.0
If we subtract 66 from 120, we get 54.
Grab the next digit (9) from the dividend, add it to 54, then carry on: 549 / 66

Let's proceed to step 6:
549 divided by 66 is 8 with a remainder of 21.
Put 8 as the next digit of the answer. 
Result so far: 6018.0
If we subtract 528 from 549, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
66 goes into 210 3 times with a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 6018.3
Deduct 198 from 210 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 8:
66 goes into 120 1 times with a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 6018.31
Subtracting 66 from 120 leaves us 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.

On to step 9:
If we divide 540 by 66, we get 8 and a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 6018.318
If we subtract 528 from 540, we 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.

Let's proceed to step 10:
66 can be fit into 120 1 times, resulting in a remainder of 54.
The next digit of our result is 1. 
Result so far: 6018.3181
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.

On to step 11:
540 divided by 66 is 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 6018.31818
The remainder is 12 after subtracting 528 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
When dividing 120 by 66, we get 1 with a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 6018.318181
If we take 66 away from 120, we end up 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.

Going ahead to step 13:
The number 66 fits into 540 8 times, leaving a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 6018.3181818
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.

Moving on to step 14:
When dividing 120 by 66, we get 1 with a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 6018.31818181
If we subtract 66 from 120, 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.

Our division results in 6018.31818181 with a remaining 5.4e-08.
