Let's divide 644000 by 54
We want to divide 644000 by 54.

Going ahead to step 1:
When dividing 6 by 54, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 54

Advancing to step 2:
54 goes into 64 1 times with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 54 from 64, we get 10.
Grab the next digit (4) from the dividend, add it to 10, then carry on: 104 / 54

On to step 3:
54 goes into 104 1 times with a remainder of 50.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 54 from 104, we get 50.
Include the next digit (0) from the dividend after 50, then repeat: 500 / 54

Moving on to step 4:
54 can be fit into 500 9 times, resulting in a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 119.0
Subtracting 486 from 500 leaves us with 14.
Bring next digit (0) of the dividend behind the 14 and repeat the process: 140 / 54

Step 5:
When dividing 140 by 54, we get 2 with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 1192.0
Subtract 108 from 140 to get 32.
Fetch the next digit (0) from the dividend, attach it to 32 and continue: 320 / 54

Moving on to step 6:
320 divided by 54 is 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 11925.0
If we take 270 away from 320, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 7:
500 divided by 54 is 9 with a remainder of 14.
The next digit of our result is 9. 
Result so far: 11925.9
Deduct 486 from 500 and we're left 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 8:
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: 11925.92
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.

Step 9:
If we divide 320 by 54, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 11925.925
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 10:
The number 54 fits into 500 9 times, leaving a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 11925.9259
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.

Going ahead to step 11:
When dividing 140 by 54, we get 2 with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 11925.92592
The remainder is 32 after subtracting 108 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 12:
320 divided by 54 is 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 11925.925925
Subtracting 270 from 320 leaves us with 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 13:
54 goes into 500 9 times with a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 11925.9259259
The remainder is 14 after subtracting 486 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 14:
140 divided by 54 is 2 with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 11925.92592592
The remainder is 32 after subtracting 108 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 11925.92592592 with a remaining 3.2e-08.
