We're dividing 13764031 by 398 
We want to figure out the number of times 13764031 can be divided by 398.

Moving on to step 1:
1 divided by 398 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 398

Advancing to step 2:
398 goes into 13 0 times with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Fetch the next digit (7) from the dividend, attach it to 13 and continue: 137 / 398

Step 3:
398 goes into 137 0 times with a remainder of 137.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 137, we get 137.
Fetch the next digit (6) from the dividend, attach it to 137 and continue: 1376 / 398

On to step 4:
398 goes into 1376 3 times with a remainder of 182.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 1194 away from 1376, we end up with 182.
Append the next digit (4) from the dividend to 182 and continue with: 1824 / 398

Going ahead to step 5:
1824 divided by 398 is 4 with a remainder of 232.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
The remainder is 232 after subtracting 1592 from 1824.
Include the next digit (0) from the dividend after 232, then repeat: 2320 / 398

Let's proceed to step 6:
When dividing 2320 by 398, we get 5 with a remainder of 330.
The next digit of our result is 5. 
Result so far: 345.0
If we take 1990 away from 2320, we end up with 330.
Grab the next digit (3) from the dividend, add it to 330, then carry on: 3303 / 398

Going ahead to step 7:
The number 398 fits into 3303 8 times, leaving a remainder of 119.
The next digit of our result is 8. 
Result so far: 3458.0
Subtracting 3184 from 3303 leaves us with 119.
Append the next digit (1) from the dividend to 119 and continue with: 1191 / 398

Step 8:
If we divide 1191 by 398, we get 2 and a remainder of 395.
Put 2 as the next digit of the answer. 
Result so far: 34582.0
Deduct 796 from 1191 and we're left with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Advancing to step 9:
The number 398 fits into 3950 9 times, leaving a remainder of 368.
The number 9 becomes the next digit in our result. 
Result so far: 34582.9
If we take 3582 away from 3950, we end up with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Going ahead to step 10:
398 goes into 3680 9 times with a remainder of 98.
Put 9 as the next digit of the answer. 
Result so far: 34582.99
Deduct 3582 from 3680 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

After the division, we end up with 34582.99 and a remainder of 0.098.
