We're dividing 215990 by 54 
Let's see how many times 54 fits into 215990.

Step 1:
2 divided by 54 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 54

On to step 2:
54 can be fit into 21 0 times, resulting in a remainder of 21.
Use 0 as the next digit of our solution. 
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 / 54

Going ahead to step 3:
215 divided by 54 is 3 with a remainder of 53.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 162 away from 215, we end up with 53.
Fetch the next digit (9) from the dividend, attach it to 53 and continue: 539 / 54

Let's proceed to step 4:
If we divide 539 by 54, we get 9 and a remainder of 53.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
The remainder is 53 after subtracting 486 from 539.
Append the next digit (9) from the dividend to 53 and continue with: 539 / 54

Going ahead to step 5:
539 divided by 54 is 9 with a remainder of 53.
Put 9 as the next digit of the answer. 
Result so far: 399.0
Deduct 486 from 539 and we're left with 53.
Take the next digit (0) from the dividend and append it to 53, then repeat: 530 / 54

Moving on to step 6:
530 divided by 54 is 9 with a remainder of 44.
Write down 9 as next digit of the result. 
Result so far: 3999.0
Subtract 486 from 530 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 7:
54 can be fit into 440 8 times, resulting in a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 3999.8
Subtract 432 from 440 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
54 can be fit into 80 1 times, resulting in a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 3999.81
Deduct 54 from 80 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 9:
When dividing 260 by 54, we get 4 with a remainder of 44.
The next digit of our result is 4. 
Result so far: 3999.814
Subtract 216 from 260 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 10:
The number 54 fits into 440 8 times, leaving a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 3999.8148
Deduct 432 from 440 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
If we divide 80 by 54, we get 1 and a remainder of 26.
The number 1 becomes the next digit in our result. 
Result so far: 3999.81481
Subtracting 54 from 80 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 12:
54 goes into 260 4 times with a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 3999.814814
Subtract 216 from 260 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 13:
54 goes into 440 8 times with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 3999.8148148
Subtracting 432 from 440 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 14:
When dividing 80 by 54, we get 1 with a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 3999.81481481
The remainder is 26 after subtracting 54 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The quotient of the division is 3999.81481481, and the remainder is 2.6e-08.
