115890 ÷ 84 
Let's see how many times 84 fits into 115890.

Step 1:
If we divide 1 by 84, we get 0 and 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.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 84

On to step 2:
84 can be fit into 11 0 times, resulting in a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 11 after subtracting 0 from 11.
Bring next digit (5) of the dividend behind the 11 and repeat the process: 115 / 84

Moving on to step 3:
If we divide 115 by 84, we get 1 and a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 84 from 115 to get 31.
Fetch the next digit (8) from the dividend, attach it to 31 and continue: 318 / 84

Moving on to step 4:
When dividing 318 by 84, we get 3 with a remainder of 66.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 66 after subtracting 252 from 318.
Bring next digit (9) of the dividend behind the 66 and repeat the process: 669 / 84

Moving on to step 5:
669 divided by 84 is 7 with a remainder of 81.
Put 7 as the next digit of the answer. 
Result so far: 137.0
The remainder is 81 after subtracting 588 from 669.
Include the next digit (0) from the dividend after 81, then repeat: 810 / 84

Moving on to step 6:
84 goes into 810 9 times with a remainder of 54.
Use 9 as the next digit of our solution. 
Result so far: 1379.0
The remainder is 54 after subtracting 756 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 7:
The number 84 fits into 540 6 times, leaving a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 1379.6
Deduct 504 from 540 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 8:
84 goes into 360 4 times with a remainder of 24.
The next digit of our result is 4. 
Result so far: 1379.64
If we take 336 away from 360, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 9:
The number 84 fits into 240 2 times, leaving a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 1379.642
Subtract 168 from 240 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 10:
720 divided by 84 is 8 with a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 1379.6428
The remainder is 48 after subtracting 672 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 11:
84 goes into 480 5 times with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 1379.64285
The remainder is 60 after subtracting 420 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 12:
When dividing 600 by 84, we get 7 with a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 1379.642857
Deduct 588 from 600 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 13:
84 can be fit into 120 1 times, resulting in a remainder of 36.
The next digit of our result is 1. 
Result so far: 1379.6428571
If we subtract 84 from 120, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 14:
360 divided by 84 is 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 1379.64285714
Subtracting 336 from 360 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 1379.64285714 and a remainder of 2.4e-08.
