Going ahead to step 5:
371 goes into 1775 4 times with a remainder of 291.
Put 4 as the next digit of the answer. 
Result so far: 114.0
Subtract 1484 from 1775 to get 291.
Include the next digit (2) from the dividend after 291, then repeat: 2912 / 371

Going ahead to step 6:
2912 divided by 371 is 7 with a remainder of 315.
The next digit of our result is 7. 
Result so far: 1147.0
Subtracting 2597 from 2912 leaves us with 315.
Include the next digit (2) from the dividend after 315, then repeat: 3152 / 371

Step 7:
3152 divided by 371 is 8 with a remainder of 184.
Put 8 as the next digit of the answer. 
Result so far: 11478.0
If we subtract 2968 from 3152, we get 184.
Include the next digit (5) from the dividend after 184, then repeat: 1845 / 371

Advancing to step 8:
When dividing 1845 by 371, we get 4 with a remainder of 361.
Record the quotient 4 as the next digit in the result. 
Result so far: 114784.0
Deduct 1484 from 1845 and we're left with 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Let's proceed to step 9:
3610 divided by 371 is 9 with a remainder of 271.
Use 9 as the next digit of our solution. 
Result so far: 114784.9
Subtracting 3339 from 3610 leaves us with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Step 10:
When dividing 2710 by 371, we get 7 with a remainder of 113.
The next digit of our result is 7. 
Result so far: 114784.97
The remainder is 113 after subtracting 2597 from 2710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Step 11:
1130 divided by 371 is 3 with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 114784.973
The remainder is 17 after subtracting 1113 from 1130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 12:
If we divide 170 by 371, we get 0 and a remainder of 170.
The number 0 becomes the next digit in our result. 
Result so far: 114784.973
Subtract 0 from 170 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 13:
The number 371 fits into 1700 4 times, leaving a remainder of 216.
Write down 4 as next digit of the result. 
Result so far: 114784.97304
Subtract 1484 from 1700 to 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.

Going ahead to step 14:
371 goes into 2160 5 times with a remainder of 305.
Write down 5 as next digit of the result. 
Result so far: 114784.973045
Subtracting 1855 from 2160 leaves us with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Advancing to step 15:
The number 371 fits into 3050 8 times, leaving a remainder of 82.
The number 8 becomes the next digit in our result. 
Result so far: 114784.9730458
Subtract 2968 from 3050 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 16:
371 goes into 820 2 times with a remainder of 78.
Use 2 as the next digit of our solution. 
Result so far: 114784.97304582
Deduct 742 from 820 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

The final result is 114784.97304582 with a remainder of 7.8e-08.
