16644061 ÷ 398 
Our goal is to divide 16644061 by 398.

On to step 1:
398 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 398

Step 2:
If we divide 16 by 398, we get 0 and a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Fetch the next digit (6) from the dividend, attach it to 16 and continue: 166 / 398

Moving on to step 3:
The number 398 fits into 166 0 times, leaving a remainder of 166.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 166 after subtracting 0 from 166.
Grab the next digit (4) from the dividend, add it to 166, then carry on: 1664 / 398

Moving on to step 4:
If we divide 1664 by 398, we get 4 and a remainder of 72.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 72 after subtracting 1592 from 1664.
Append the next digit (4) from the dividend to 72 and continue with: 724 / 398

Let's proceed to step 5:
If we divide 724 by 398, we get 1 and a remainder of 326.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
Deduct 398 from 724 and we're left with 326.
Bring next digit (0) of the dividend behind the 326 and repeat the process: 3260 / 398

Let's proceed to step 6:
If we divide 3260 by 398, we get 8 and a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 418.0
If we take 3184 away from 3260, we end up with 76.
Take the next digit (6) from the dividend and append it to 76, then repeat: 766 / 398

Step 7:
398 goes into 766 1 times with a remainder of 368.
Record the quotient 1 as the next digit in the result. 
Result so far: 4181.0
If we subtract 398 from 766, we get 368.
Bring next digit (1) of the dividend behind the 368 and repeat the process: 3681 / 398

Let's proceed to step 8:
398 can be fit into 3681 9 times, resulting in a remainder of 99.
Record the quotient 9 as the next digit in the result. 
Result so far: 41819.0
The remainder is 99 after subtracting 3582 from 3681.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

On to step 9:
398 can be fit into 990 2 times, resulting in a remainder of 194.
Put 2 as the next digit of the answer. 
Result so far: 41819.2
Subtract 796 from 990 to get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Step 10:
If we divide 1940 by 398, we get 4 and a remainder of 348.
The number 4 becomes the next digit in our result. 
Result so far: 41819.24
If we take 1592 away from 1940, we end up with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

On to step 11:
The number 398 fits into 3480 8 times, leaving a remainder of 296.
Record the quotient 8 as the next digit in the result. 
Result so far: 41819.248
The remainder is 296 after subtracting 3184 from 3480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Going ahead to step 12:
2960 divided by 398 is 7 with a remainder of 174.
The next digit of our result is 7. 
Result so far: 41819.2487
Subtract 2786 from 2960 to get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Step 13:
398 goes into 1740 4 times with a remainder of 148.
Write down 4 as next digit of the result. 
Result so far: 41819.24874
The remainder is 148 after subtracting 1592 from 1740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Let's proceed to step 14:
1480 divided by 398 is 3 with a remainder of 286.
Use 3 as the next digit of our solution. 
Result so far: 41819.248743
If we take 1194 away from 1480, we end up with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Going ahead to step 15:
398 goes into 2860 7 times with a remainder of 74.
Use 7 as the next digit of our solution. 
Result so far: 41819.2487437
Subtracting 2786 from 2860 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 16:
398 can be fit into 740 1 times, resulting in a remainder of 342.
Put 1 as the next digit of the answer. 
Result so far: 41819.24874371
Subtracting 398 from 740 leaves us with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

In conclusion, the division gives 41819.24874371 with a balance of 3.42e-07.
