We look at the division of 1241605 by 398 
Our goal is to divide 1241605 by 398.

Moving on to step 1:
1 divided by 398 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 398

Advancing to step 2:
398 goes into 12 0 times with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 398

Step 3:
The number 398 fits into 124 0 times, leaving a remainder of 124.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 124 leaves us with 124.
Append the next digit (1) from the dividend to 124 and continue with: 1241 / 398

Going ahead to step 4:
1241 divided by 398 is 3 with a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 47 after subtracting 1194 from 1241.
Fetch the next digit (6) from the dividend, attach it to 47 and continue: 476 / 398

Advancing to step 5:
If we divide 476 by 398, we get 1 and a remainder of 78.
Write down 1 as next digit of the result. 
Result so far: 31.0
If we subtract 398 from 476, we get 78.
Grab the next digit (0) from the dividend, add it to 78, then carry on: 780 / 398

Going ahead to step 6:
The number 398 fits into 780 1 times, leaving a remainder of 382.
Put 1 as the next digit of the answer. 
Result so far: 311.0
Subtract 398 from 780 to get 382.
Include the next digit (5) from the dividend after 382, then repeat: 3825 / 398

Moving on to step 7:
398 can be fit into 3825 9 times, resulting in a remainder of 243.
The next digit of our result is 9. 
Result so far: 3119.0
Deduct 3582 from 3825 and we're left with 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Going ahead to step 8:
If we divide 2430 by 398, we get 6 and a remainder of 42.
Use 6 as the next digit of our solution. 
Result so far: 3119.6
The remainder is 42 after subtracting 2388 from 2430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 9:
398 goes into 420 1 times with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 3119.61
Subtracting 398 from 420 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 10:
220 divided by 398 is 0 with a remainder of 220.
Use 0 as the next digit of our solution. 
Result so far: 3119.61
Subtracting 0 from 220 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 11:
2200 divided by 398 is 5 with a remainder of 210.
The next digit of our result is 5. 
Result so far: 3119.6105
Subtracting 1990 from 2200 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 12:
398 can be fit into 2100 5 times, resulting in a remainder of 110.
Use 5 as the next digit of our solution. 
Result so far: 3119.61055
Subtract 1990 from 2100 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

The final result is 3119.61055 with a remainder of 0.00011.
