Let's divide 18691577 by 398
We want to divide 18691577 by 398.

Going ahead to step 1:
The number 398 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 398

Going ahead to step 2:
The number 398 fits into 18 0 times, leaving a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 398

Step 3:
398 goes into 186 0 times with a remainder of 186.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 186, we end up with 186.
Take the next digit (9) from the dividend and append it to 186, then repeat: 1869 / 398

Moving on to step 4:
If we divide 1869 by 398, we get 4 and a remainder of 277.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 1592 from 1869 to get 277.
Bring next digit (1) of the dividend behind the 277 and repeat the process: 2771 / 398

On to step 5:
The number 398 fits into 2771 6 times, leaving a remainder of 383.
Write down 6 as next digit of the result. 
Result so far: 46.0
Deduct 2388 from 2771 and we're left with 383.
Fetch the next digit (5) from the dividend, attach it to 383 and continue: 3835 / 398

Let's proceed to step 6:
398 can be fit into 3835 9 times, resulting in a remainder of 253.
Put 9 as the next digit of the answer. 
Result so far: 469.0
If we take 3582 away from 3835, we end up with 253.
Grab the next digit (7) from the dividend, add it to 253, then carry on: 2537 / 398

Step 7:
If we divide 2537 by 398, we get 6 and a remainder of 149.
Write down 6 as next digit of the result. 
Result so far: 4696.0
If we subtract 2388 from 2537, we get 149.
Bring next digit (7) of the dividend behind the 149 and repeat the process: 1497 / 398

Advancing to step 8:
If we divide 1497 by 398, we get 3 and a remainder of 303.
The next digit of our result is 3. 
Result so far: 46963.0
If we take 1194 away from 1497, we end up with 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

On to step 9:
398 can be fit into 3030 7 times, resulting in a remainder of 244.
Put 7 as the next digit of the answer. 
Result so far: 46963.7
The remainder is 244 after subtracting 2786 from 3030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Let's proceed to step 10:
398 can be fit into 2440 6 times, resulting in a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 46963.76
If we take 2388 away from 2440, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 11:
398 can be fit into 520 1 times, resulting in a remainder of 122.
Use 1 as the next digit of our solution. 
Result so far: 46963.761
If we take 398 away from 520, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 12:
1220 divided by 398 is 3 with a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 46963.7613
If we take 1194 away from 1220, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 13:
The number 398 fits into 260 0 times, leaving a remainder of 260.
Use 0 as the next digit of our solution. 
Result so far: 46963.7613
Subtracting 0 from 260 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 14:
The number 398 fits into 2600 6 times, leaving a remainder of 212.
Write down 6 as next digit of the result. 
Result so far: 46963.761306
Subtract 2388 from 2600 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

On to step 15:
If we divide 2120 by 398, we get 5 and a remainder of 130.
Put 5 as the next digit of the answer. 
Result so far: 46963.7613065
Deduct 1990 from 2120 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 16:
The number 398 fits into 1300 3 times, leaving a remainder of 106.
The next digit of our result is 3. 
Result so far: 46963.76130653
Subtracting 1194 from 1300 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Our division results in 46963.76130653 with a remaining 1.06e-07.
