We divide 1239969 by 398
We're looking to find how many times 398 goes into 1239969.

Going ahead to step 1:
398 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 398

Moving on to step 2:
12 divided by 398 is 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 398

Going ahead to step 3:
123 divided by 398 is 0 with a remainder of 123.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 123 and we're left with 123.
Grab the next digit (9) from the dividend, add it to 123, then carry on: 1239 / 398

On to step 4:
The number 398 fits into 1239 3 times, leaving a remainder of 45.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 1194 away from 1239, we end up with 45.
Grab the next digit (9) from the dividend, add it to 45, then carry on: 459 / 398

On to step 5:
398 goes into 459 1 times with a remainder of 61.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
If we subtract 398 from 459, we get 61.
Bring next digit (6) of the dividend behind the 61 and repeat the process: 616 / 398

Let's proceed to step 6:
398 goes into 616 1 times with a remainder of 218.
Put 1 as the next digit of the answer. 
Result so far: 311.0
If we take 398 away from 616, we end up with 218.
Bring next digit (9) of the dividend behind the 218 and repeat the process: 2189 / 398

Step 7:
398 can be fit into 2189 5 times, resulting in a remainder of 199.
Use 5 as the next digit of our solution. 
Result so far: 3115.0
If we take 1990 away from 2189, we end up with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Advancing to step 8:
398 can be fit into 1990 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 3115.5
The remainder is 0 after subtracting 1990 from 1990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
The number 398 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3115.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
If we divide 0 by 398, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3115.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 3115.5 with a remaining 0.0.
