255615 ÷ 84 
We want to figure out the number of times 255615 can be divided by 84.

Going ahead to step 1:
If we divide 2 by 84, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 84

On to step 2:
If we divide 25 by 84, we get 0 and a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Append the next digit (5) from the dividend to 25 and continue with: 255 / 84

Going ahead to step 3:
84 can be fit into 255 3 times, resulting in a remainder of 3.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 252 from 255 leaves us with 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 84

Let's proceed to step 4:
If we divide 36 by 84, we get 0 and a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
If we subtract 0 from 36, we get 36.
Take the next digit (1) from the dividend and append it to 36, then repeat: 361 / 84

On to step 5:
84 can be fit into 361 4 times, resulting in a remainder of 25.
The number 4 becomes the next digit in our result. 
Result so far: 304.0
If we subtract 336 from 361, we get 25.
Include the next digit (5) from the dividend after 25, then repeat: 255 / 84

Step 6:
The number 84 fits into 255 3 times, leaving a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 3043.0
Subtract 252 from 255 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
30 divided by 84 is 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 3043.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
84 can be fit into 300 3 times, resulting in a remainder of 48.
The number 3 becomes the next digit in our result. 
Result so far: 3043.03
Deduct 252 from 300 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 9:
The number 84 fits into 480 5 times, leaving a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 3043.035
Subtracting 420 from 480 leaves us with 60.
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 10:
600 divided by 84 is 7 with a remainder of 12.
The next digit of our result is 7. 
Result so far: 3043.0357
Subtract 588 from 600 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 11:
When dividing 120 by 84, we get 1 with a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 3043.03571
If we take 84 away from 120, we end up 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.

Advancing to step 12:
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: 3043.035714
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.

Step 13:
84 can be fit into 240 2 times, resulting in a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 3043.0357142
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.

Step 14:
If we divide 720 by 84, we get 8 and a remainder of 48.
The next digit of our result is 8. 
Result so far: 3043.03571428
If we take 672 away from 720, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The quotient of the division is 3043.03571428, and the remainder is 4.8e-08.
