Let's divide 115990 by 84
Let's see how many times 84 fits into 115990.

On to step 1:
The number 84 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 84

Advancing to step 2:
11 divided by 84 is 0 with a remainder of 11.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 11, we end up with 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 84

Step 3:
The number 84 fits into 115 1 times, leaving a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 84 from 115 leaves us with 31.
Grab the next digit (9) from the dividend, add it to 31, then carry on: 319 / 84

Advancing to step 4:
84 goes into 319 3 times with a remainder of 67.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 252 from 319 and we're left with 67.
Append the next digit (9) from the dividend to 67 and continue with: 679 / 84

Going ahead to step 5:
If we divide 679 by 84, we get 8 and a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 138.0
If we subtract 672 from 679, we get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 84

Moving on to step 6:
84 goes into 70 0 times with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 1380.0
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 7:
If we divide 700 by 84, we get 8 and a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 1380.8
Subtract 672 from 700 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 8:
The number 84 fits into 280 3 times, leaving a remainder of 28.
Put 3 as the next digit of the answer. 
Result so far: 1380.83
The remainder is 28 after subtracting 252 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
280 divided by 84 is 3 with a remainder of 28.
Put 3 as the next digit of the answer. 
Result so far: 1380.833
The remainder is 28 after subtracting 252 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The quotient of the division is 1380.833, and the remainder is 0.0028.
