We divide 639879 by 54
Our goal is to divide 639879 by 54.

On to step 1:
If we divide 6 by 54, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 54

Advancing to step 2:
If we divide 63 by 54, we get 1 and a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 54 away from 63, we end up with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 54

Step 3:
The number 54 fits into 99 1 times, leaving a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we subtract 54 from 99, we get 45.
Include the next digit (8) from the dividend after 45, then repeat: 458 / 54

Advancing to step 4:
458 divided by 54 is 8 with a remainder of 26.
The next digit of our result is 8. 
Result so far: 118.0
Deduct 432 from 458 and we're left with 26.
Bring next digit (7) of the dividend behind the 26 and repeat the process: 267 / 54

Advancing to step 5:
When dividing 267 by 54, we get 4 with a remainder of 51.
The number 4 becomes the next digit in our result. 
Result so far: 1184.0
Subtracting 216 from 267 leaves us with 51.
Bring next digit (9) of the dividend behind the 51 and repeat the process: 519 / 54

Step 6:
54 goes into 519 9 times with a remainder of 33.
Put 9 as the next digit of the answer. 
Result so far: 11849.0
Subtracting 486 from 519 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 7:
54 can be fit into 330 6 times, resulting in a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 11849.6
Subtract 324 from 330 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
60 divided by 54 is 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 11849.61
If we take 54 away from 60, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
54 goes into 60 1 times with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 11849.611
If we subtract 54 from 60, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The quotient of the division is 11849.611, and the remainder is 0.0006.
