17724822 ÷ 398 
We want to figure out the number of times 17724822 can be divided by 398.

Going ahead to step 1:
1 divided by 398 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 398

Let's proceed to step 2:
When dividing 17 by 398, we get 0 with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Grab the next digit (7) from the dividend, add it to 17, then carry on: 177 / 398

Let's proceed to step 3:
The number 398 fits into 177 0 times, leaving a remainder of 177.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 177, we get 177.
Grab the next digit (2) from the dividend, add it to 177, then carry on: 1772 / 398

Moving on to step 4:
If we divide 1772 by 398, we get 4 and a remainder of 180.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 1592 away from 1772, we end up with 180.
Fetch the next digit (4) from the dividend, attach it to 180 and continue: 1804 / 398

Advancing to step 5:
When dividing 1804 by 398, we get 4 with a remainder of 212.
Use 4 as the next digit of our solution. 
Result so far: 44.0
Deduct 1592 from 1804 and we're left with 212.
Take the next digit (8) from the dividend and append it to 212, then repeat: 2128 / 398

Step 6:
If we divide 2128 by 398, we get 5 and a remainder of 138.
The number 5 becomes the next digit in our result. 
Result so far: 445.0
Deduct 1990 from 2128 and we're left with 138.
Append the next digit (2) from the dividend to 138 and continue with: 1382 / 398

On to step 7:
The number 398 fits into 1382 3 times, leaving a remainder of 188.
Put 3 as the next digit of the answer. 
Result so far: 4453.0
If we take 1194 away from 1382, we end up with 188.
Include the next digit (2) from the dividend after 188, then repeat: 1882 / 398

On to step 8:
If we divide 1882 by 398, we get 4 and a remainder of 290.
The next digit of our result is 4. 
Result so far: 44534.0
If we subtract 1592 from 1882, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

On to step 9:
The number 398 fits into 2900 7 times, leaving a remainder of 114.
Record the quotient 7 as the next digit in the result. 
Result so far: 44534.7
Subtract 2786 from 2900 to get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Step 10:
1140 divided by 398 is 2 with a remainder of 344.
Put 2 as the next digit of the answer. 
Result so far: 44534.72
If we take 796 away from 1140, we end up with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

On to step 11:
398 can be fit into 3440 8 times, resulting in a remainder of 256.
The next digit of our result is 8. 
Result so far: 44534.728
If we take 3184 away from 3440, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Let's proceed to step 12:
When dividing 2560 by 398, we get 6 with a remainder of 172.
Put 6 as the next digit of the answer. 
Result so far: 44534.7286
Deduct 2388 from 2560 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Step 13:
If we divide 1720 by 398, we get 4 and a remainder of 128.
Record the quotient 4 as the next digit in the result. 
Result so far: 44534.72864
Subtract 1592 from 1720 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 14:
If we divide 1280 by 398, we get 3 and a remainder of 86.
The next digit of our result is 3. 
Result so far: 44534.728643
Subtracting 1194 from 1280 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 15:
398 can be fit into 860 2 times, resulting in a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 44534.7286432
Deduct 796 from 860 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 16:
640 divided by 398 is 1 with a remainder of 242.
Use 1 as the next digit of our solution. 
Result so far: 44534.72864321
Subtracting 398 from 640 leaves us with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

The quotient of the division is 44534.72864321, and the remainder is 2.42e-07.
