We divide 1948575 by 398
We want to figure out the number of times 1948575 can be divided by 398.

On to step 1:
398 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 398

Going ahead to step 2:
If we divide 19 by 398, we get 0 and a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Append the next digit (4) from the dividend to 19 and continue with: 194 / 398

On to step 3:
If we divide 194 by 398, we get 0 and a remainder of 194.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 194 leaves us with 194.
Append the next digit (8) from the dividend to 194 and continue with: 1948 / 398

Step 4:
1948 divided by 398 is 4 with a remainder of 356.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 1592 from 1948 and we're left with 356.
Include the next digit (5) from the dividend after 356, then repeat: 3565 / 398

Moving on to step 5:
The number 398 fits into 3565 8 times, leaving a remainder of 381.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
The remainder is 381 after subtracting 3184 from 3565.
Include the next digit (7) from the dividend after 381, then repeat: 3817 / 398

Let's proceed to step 6:
If we divide 3817 by 398, we get 9 and a remainder of 235.
Record the quotient 9 as the next digit in the result. 
Result so far: 489.0
The remainder is 235 after subtracting 3582 from 3817.
Take the next digit (5) from the dividend and append it to 235, then repeat: 2355 / 398

Step 7:
If we divide 2355 by 398, we get 5 and a remainder of 365.
The number 5 becomes the next digit in our result. 
Result so far: 4895.0
The remainder is 365 after subtracting 1990 from 2355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

On to step 8:
398 goes into 3650 9 times with a remainder of 68.
The number 9 becomes the next digit in our result. 
Result so far: 4895.9
Subtract 3582 from 3650 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 9:
398 can be fit into 680 1 times, resulting in a remainder of 282.
Write down 1 as next digit of the result. 
Result so far: 4895.91
Subtracting 398 from 680 leaves us with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Advancing to step 10:
398 can be fit into 2820 7 times, resulting in a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 4895.917
If we subtract 2786 from 2820, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 11:
The number 398 fits into 340 0 times, leaving a remainder of 340.
Use 0 as the next digit of our solution. 
Result so far: 4895.917
Subtracting 0 from 340 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 12:
398 can be fit into 3400 8 times, resulting in a remainder of 216.
Use 8 as the next digit of our solution. 
Result so far: 4895.91708
If we subtract 3184 from 3400, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Moving on to step 13:
398 goes into 2160 5 times with a remainder of 170.
Put 5 as the next digit of the answer. 
Result so far: 4895.917085
If we take 1990 away from 2160, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 14:
If we divide 1700 by 398, we get 4 and a remainder of 108.
Record the quotient 4 as the next digit in the result. 
Result so far: 4895.9170854
Subtracting 1592 from 1700 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Let's proceed to step 15:
398 goes into 1080 2 times with a remainder of 284.
The number 2 becomes the next digit in our result. 
Result so far: 4895.91708542
Deduct 796 from 1080 and we're left with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

The final result is 4895.91708542 with a remainder of 2.84e-07.
