We look at the division of 66339206 by 398 
Let's see how many times 398 fits into 66339206.

Moving on to step 1:
If we divide 6 by 398, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 398

On to step 2:
66 divided by 398 is 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Include the next digit (3) from the dividend after 66, then repeat: 663 / 398

Let's proceed to step 3:
If we divide 663 by 398, we get 1 and a remainder of 265.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 398 away from 663, we end up with 265.
Grab the next digit (3) from the dividend, add it to 265, then carry on: 2653 / 398

Step 4:
398 can be fit into 2653 6 times, resulting in a remainder of 265.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
The remainder is 265 after subtracting 2388 from 2653.
Grab the next digit (9) from the dividend, add it to 265, then carry on: 2659 / 398

Let's proceed to step 5:
The number 398 fits into 2659 6 times, leaving a remainder of 271.
Put 6 as the next digit of the answer. 
Result so far: 166.0
Subtracting 2388 from 2659 leaves us with 271.
Take the next digit (2) from the dividend and append it to 271, then repeat: 2712 / 398

Going ahead to step 6:
When dividing 2712 by 398, we get 6 with a remainder of 324.
Put 6 as the next digit of the answer. 
Result so far: 1666.0
Subtracting 2388 from 2712 leaves us with 324.
Include the next digit (0) from the dividend after 324, then repeat: 3240 / 398

Advancing to step 7:
3240 divided by 398 is 8 with a remainder of 56.
The next digit of our result is 8. 
Result so far: 16668.0
Subtract 3184 from 3240 to get 56.
Bring next digit (6) of the dividend behind the 56 and repeat the process: 566 / 398

Advancing to step 8:
398 can be fit into 566 1 times, resulting in a remainder of 168.
Put 1 as the next digit of the answer. 
Result so far: 166681.0
If we subtract 398 from 566, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

On to step 9:
398 goes into 1680 4 times with a remainder of 88.
Record the quotient 4 as the next digit in the result. 
Result so far: 166681.4
Deduct 1592 from 1680 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 10:
The number 398 fits into 880 2 times, leaving a remainder of 84.
The next digit of our result is 2. 
Result so far: 166681.42
The remainder is 84 after subtracting 796 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 11:
If we divide 840 by 398, we get 2 and a remainder of 44.
The next digit of our result is 2. 
Result so far: 166681.422
If we take 796 away from 840, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The quotient of the division is 166681.422, and the remainder is 0.0044.
