20164448 ÷ 398 
We want to divide 20164448 by 398.

Advancing to step 1:
398 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 398

On to step 2:
When dividing 20 by 398, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Bring next digit (1) of the dividend behind the 20 and repeat the process: 201 / 398

Moving on to step 3:
398 can be fit into 201 0 times, resulting in a remainder of 201.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 201 to get 201.
Include the next digit (6) from the dividend after 201, then repeat: 2016 / 398

Going ahead to step 4:
398 goes into 2016 5 times with a remainder of 26.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 1990 away from 2016, we end up with 26.
Take the next digit (4) from the dividend and append it to 26, then repeat: 264 / 398

Going ahead to step 5:
When dividing 264 by 398, we get 0 with a remainder of 264.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
If we take 0 away from 264, we end up with 264.
Bring next digit (4) of the dividend behind the 264 and repeat the process: 2644 / 398

On to step 6:
2644 divided by 398 is 6 with a remainder of 256.
Put 6 as the next digit of the answer. 
Result so far: 506.0
The remainder is 256 after subtracting 2388 from 2644.
Fetch the next digit (4) from the dividend, attach it to 256 and continue: 2564 / 398

On to step 7:
398 can be fit into 2564 6 times, resulting in a remainder of 176.
The next digit of our result is 6. 
Result so far: 5066.0
If we take 2388 away from 2564, we end up with 176.
Append the next digit (8) from the dividend to 176 and continue with: 1768 / 398

Moving on to step 8:
If we divide 1768 by 398, we get 4 and a remainder of 176.
Put 4 as the next digit of the answer. 
Result so far: 50664.0
Deduct 1592 from 1768 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 9:
398 goes into 1760 4 times with a remainder of 168.
Write down 4 as next digit of the result. 
Result so far: 50664.4
Subtract 1592 from 1760 to 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.

Advancing to step 10:
1680 divided by 398 is 4 with a remainder of 88.
Use 4 as the next digit of our solution. 
Result so far: 50664.44
Subtracting 1592 from 1680 leaves us 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.

The quotient of the division is 50664.44, and the remainder is 0.088.
