Let's divide 23520816 by 398
We want to divide 23520816 by 398.

Let's proceed to step 1:
The number 398 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 398

On to step 2:
When dividing 23 by 398, we get 0 with a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 23 leaves us with 23.
Append the next digit (5) from the dividend to 23 and continue with: 235 / 398

Advancing to step 3:
398 goes into 235 0 times with a remainder of 235.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 235 and we're left with 235.
Append the next digit (2) from the dividend to 235 and continue with: 2352 / 398

Let's proceed to step 4:
398 goes into 2352 5 times with a remainder of 362.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 1990 from 2352 and we're left with 362.
Fetch the next digit (0) from the dividend, attach it to 362 and continue: 3620 / 398

Advancing to step 5:
If we divide 3620 by 398, we get 9 and a remainder of 38.
The next digit of our result is 9. 
Result so far: 59.0
Subtracting 3582 from 3620 leaves us with 38.
Append the next digit (8) from the dividend to 38 and continue with: 388 / 398

Going ahead to step 6:
If we divide 388 by 398, we get 0 and a remainder of 388.
Put 0 as the next digit of the answer. 
Result so far: 590.0
If we take 0 away from 388, we end up with 388.
Append the next digit (1) from the dividend to 388 and continue with: 3881 / 398

Let's proceed to step 7:
When dividing 3881 by 398, we get 9 with a remainder of 299.
Put 9 as the next digit of the answer. 
Result so far: 5909.0
If we take 3582 away from 3881, we end up with 299.
Append the next digit (6) from the dividend to 299 and continue with: 2996 / 398

Step 8:
398 can be fit into 2996 7 times, resulting in a remainder of 210.
The next digit of our result is 7. 
Result so far: 59097.0
If we subtract 2786 from 2996, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 9:
398 goes into 2100 5 times with a remainder of 110.
The next digit of our result is 5. 
Result so far: 59097.5
If we take 1990 away from 2100, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 10:
If we divide 1100 by 398, we get 2 and a remainder of 304.
The next digit of our result is 2. 
Result so far: 59097.52
If we take 796 away from 1100, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

On to step 11:
398 goes into 3040 7 times with a remainder of 254.
Record the quotient 7 as the next digit in the result. 
Result so far: 59097.527
If we take 2786 away from 3040, we end up with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Moving on to step 12:
398 goes into 2540 6 times with a remainder of 152.
The number 6 becomes the next digit in our result. 
Result so far: 59097.5276
Subtract 2388 from 2540 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 13:
When dividing 1520 by 398, we get 3 with a remainder of 326.
Use 3 as the next digit of our solution. 
Result so far: 59097.52763
Subtract 1194 from 1520 to get 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Let's proceed to step 14:
When dividing 3260 by 398, we get 8 with a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 59097.527638
Subtract 3184 from 3260 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 15:
398 can be fit into 760 1 times, resulting in a remainder of 362.
Use 1 as the next digit of our solution. 
Result so far: 59097.5276381
If we subtract 398 from 760, we get 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Moving on to step 16:
3620 divided by 398 is 9 with a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 59097.52763819
If we subtract 3582 from 3620, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

After the division, we end up with 59097.52763819 and a remainder of 3.8e-08.
