Let's divide 17177161 by 398
We want to divide 17177161 by 398.

Advancing to step 1:
If we divide 1 by 398, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 398

On to step 2:
398 can be fit into 17 0 times, resulting in a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Include the next digit (1) from the dividend after 17, then repeat: 171 / 398

On to step 3:
171 divided by 398 is 0 with a remainder of 171.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 171 to get 171.
Include the next digit (7) from the dividend after 171, then repeat: 1717 / 398

Going ahead to step 4:
398 goes into 1717 4 times with a remainder of 125.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 125 after subtracting 1592 from 1717.
Fetch the next digit (7) from the dividend, attach it to 125 and continue: 1257 / 398

Step 5:
1257 divided by 398 is 3 with a remainder of 63.
The next digit of our result is 3. 
Result so far: 43.0
Subtracting 1194 from 1257 leaves us with 63.
Append the next digit (1) from the dividend to 63 and continue with: 631 / 398

Moving on to step 6:
If we divide 631 by 398, we get 1 and a remainder of 233.
Record the quotient 1 as the next digit in the result. 
Result so far: 431.0
The remainder is 233 after subtracting 398 from 631.
Include the next digit (6) from the dividend after 233, then repeat: 2336 / 398

Advancing to step 7:
398 can be fit into 2336 5 times, resulting in a remainder of 346.
Use 5 as the next digit of our solution. 
Result so far: 4315.0
The remainder is 346 after subtracting 1990 from 2336.
Bring next digit (1) of the dividend behind the 346 and repeat the process: 3461 / 398

Going ahead to step 8:
The number 398 fits into 3461 8 times, leaving a remainder of 277.
The number 8 becomes the next digit in our result. 
Result so far: 43158.0
Deduct 3184 from 3461 and we're left with 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Going ahead to step 9:
398 can be fit into 2770 6 times, resulting in a remainder of 382.
The next digit of our result is 6. 
Result so far: 43158.6
If we take 2388 away from 2770, we end up with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Let's proceed to step 10:
398 can be fit into 3820 9 times, resulting in a remainder of 238.
The number 9 becomes the next digit in our result. 
Result so far: 43158.69
The remainder is 238 after subtracting 3582 from 3820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

On to step 11:
If we divide 2380 by 398, we get 5 and a remainder of 390.
The next digit of our result is 5. 
Result so far: 43158.695
Deduct 1990 from 2380 and we're left with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Moving on to step 12:
The number 398 fits into 3900 9 times, leaving a remainder of 318.
Record the quotient 9 as the next digit in the result. 
Result so far: 43158.6959
Subtracting 3582 from 3900 leaves us with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Let's proceed to step 13:
When dividing 3180 by 398, we get 7 with a remainder of 394.
Use 7 as the next digit of our solution. 
Result so far: 43158.69597
The remainder is 394 after subtracting 2786 from 3180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Moving on to step 14:
3940 divided by 398 is 9 with a remainder of 358.
Put 9 as the next digit of the answer. 
Result so far: 43158.695979
Deduct 3582 from 3940 and we're left with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Going ahead to step 15:
When dividing 3580 by 398, we get 8 with a remainder of 396.
The next digit of our result is 8. 
Result so far: 43158.6959798
Deduct 3184 from 3580 and we're left with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Going ahead to step 16:
The number 398 fits into 3960 9 times, leaving a remainder of 378.
Record the quotient 9 as the next digit in the result. 
Result so far: 43158.69597989
Subtract 3582 from 3960 to get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

The final result is 43158.69597989 with a remainder of 3.78e-07.
