14203925 ÷ 398 
Our goal is to divide 14203925 by 398.

On to step 1:
398 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 398

Let's proceed to step 2:
398 can be fit into 14 0 times, resulting in a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 398

Let's proceed to step 3:
398 goes into 142 0 times with a remainder of 142.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 142 after subtracting 0 from 142.
Bring next digit (0) of the dividend behind the 142 and repeat the process: 1420 / 398

Going ahead to step 4:
1420 divided by 398 is 3 with a remainder of 226.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 1194 from 1420 leaves us with 226.
Take the next digit (3) from the dividend and append it to 226, then repeat: 2263 / 398

Going ahead to step 5:
If we divide 2263 by 398, we get 5 and a remainder of 273.
Put 5 as the next digit of the answer. 
Result so far: 35.0
If we take 1990 away from 2263, we end up with 273.
Fetch the next digit (9) from the dividend, attach it to 273 and continue: 2739 / 398

Let's proceed to step 6:
2739 divided by 398 is 6 with a remainder of 351.
The number 6 becomes the next digit in our result. 
Result so far: 356.0
Subtract 2388 from 2739 to get 351.
Grab the next digit (2) from the dividend, add it to 351, then carry on: 3512 / 398

Moving on to step 7:
3512 divided by 398 is 8 with a remainder of 328.
The next digit of our result is 8. 
Result so far: 3568.0
If we subtract 3184 from 3512, we get 328.
Take the next digit (5) from the dividend and append it to 328, then repeat: 3285 / 398

Advancing to step 8:
When dividing 3285 by 398, we get 8 with a remainder of 101.
Write down 8 as next digit of the result. 
Result so far: 35688.0
If we take 3184 away from 3285, we end up with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

On to step 9:
The number 398 fits into 1010 2 times, leaving a remainder of 214.
Put 2 as the next digit of the answer. 
Result so far: 35688.2
If we subtract 796 from 1010, we get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Step 10:
When dividing 2140 by 398, we get 5 with a remainder of 150.
Put 5 as the next digit of the answer. 
Result so far: 35688.25
If we take 1990 away from 2140, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 11:
The number 398 fits into 1500 3 times, leaving a remainder of 306.
Record the quotient 3 as the next digit in the result. 
Result so far: 35688.253
Deduct 1194 from 1500 and we're left with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Moving on to step 12:
3060 divided by 398 is 7 with a remainder of 274.
The next digit of our result is 7. 
Result so far: 35688.2537
Subtracting 2786 from 3060 leaves us with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Step 13:
398 can be fit into 2740 6 times, resulting in a remainder of 352.
The number 6 becomes the next digit in our result. 
Result so far: 35688.25376
If we subtract 2388 from 2740, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Advancing to step 14:
398 goes into 3520 8 times with a remainder of 336.
The next digit of our result is 8. 
Result so far: 35688.253768
Subtracting 3184 from 3520 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Let's proceed to step 15:
398 can be fit into 3360 8 times, resulting in a remainder of 176.
The number 8 becomes the next digit in our result. 
Result so far: 35688.2537688
The remainder is 176 after subtracting 3184 from 3360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

The quotient of the division is 35688.2537688, and the remainder is 1.76e-06.
