We look at the division of 215542 by 84 
We want to divide 215542 by 84.

Advancing to step 1:
2 divided by 84 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 84

On to step 2:
If we divide 21 by 84, we get 0 and a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 84

Let's proceed to step 3:
215 divided by 84 is 2 with a remainder of 47.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 168 from 215 to get 47.
Include the next digit (5) from the dividend after 47, then repeat: 475 / 84

Moving on to step 4:
475 divided by 84 is 5 with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 25.0
If we subtract 420 from 475, we get 55.
Bring next digit (4) of the dividend behind the 55 and repeat the process: 554 / 84

Advancing to step 5:
When dividing 554 by 84, we get 6 with a remainder of 50.
Put 6 as the next digit of the answer. 
Result so far: 256.0
If we take 504 away from 554, we end up with 50.
Include the next digit (2) from the dividend after 50, then repeat: 502 / 84

On to step 6:
If we divide 502 by 84, we get 5 and a remainder of 82.
The next digit of our result is 5. 
Result so far: 2565.0
The remainder is 82 after subtracting 420 from 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 7:
The number 84 fits into 820 9 times, leaving a remainder of 64.
Write down 9 as next digit of the result. 
Result so far: 2565.9
Subtracting 756 from 820 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 8:
640 divided by 84 is 7 with a remainder of 52.
Put 7 as the next digit of the answer. 
Result so far: 2565.97
The remainder is 52 after subtracting 588 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 9:
The number 84 fits into 520 6 times, leaving a remainder of 16.
The next digit of our result is 6. 
Result so far: 2565.976
If we take 504 away from 520, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 10:
When dividing 160 by 84, we get 1 with a remainder of 76.
Write down 1 as next digit of the result. 
Result so far: 2565.9761
If we take 84 away from 160, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 11:
If we divide 760 by 84, we get 9 and a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 2565.97619
Subtract 756 from 760 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 12:
When dividing 40 by 84, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 2565.97619
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 13:
When dividing 400 by 84, we get 4 with a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 2565.9761904
Deduct 336 from 400 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 14:
84 goes into 640 7 times with a remainder of 52.
Use 7 as the next digit of our solution. 
Result so far: 2565.97619047
If we take 588 away from 640, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final outcome is 2565.97619047, with a leftover of 5.2e-08.
