Let's divide 810023 by 54
Let's see how many times 54 fits into 810023.

Going ahead to step 1:
If we divide 8 by 54, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 54

Advancing to step 2:
54 can be fit into 81 1 times, resulting in a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 54 from 81, we get 27.
Take the next digit (0) from the dividend and append it to 27, then repeat: 270 / 54

Advancing to step 3:
When dividing 270 by 54, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 15.0
Subtracting 270 from 270 leaves us with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 54

Advancing to step 4:
The number 54 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 150.0
Deduct 0 from 0 and we're left with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 54

Going ahead to step 5:
The number 54 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 1500.0
If we take 0 away from 2, we end up with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 54

On to step 6:
When dividing 23 by 54, we get 0 with a remainder of 23.
The next digit of our result is 0. 
Result so far: 15000.0
Deduct 0 from 23 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 7:
When dividing 230 by 54, we get 4 with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 15000.4
Subtracting 216 from 230 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
54 can be fit into 140 2 times, resulting in a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 15000.42
If we take 108 away from 140, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 9:
54 goes into 320 5 times with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 15000.425
Subtract 270 from 320 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
54 goes into 500 9 times with a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 15000.4259
Subtract 486 from 500 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 11:
54 can be fit into 140 2 times, resulting in a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 15000.42592
If we subtract 108 from 140, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 12:
If we divide 320 by 54, we get 5 and a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 15000.425925
Subtract 270 from 320 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 13:
When dividing 500 by 54, we get 9 with a remainder of 14.
Put 9 as the next digit of the answer. 
Result so far: 15000.4259259
If we take 486 away from 500, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 14:
When dividing 140 by 54, we get 2 with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 15000.42592592
If we take 108 away from 140, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 15000.42592592 and a remainder of 3.2e-08.
