Let's divide 545409 by 10
Our goal is to divide 545409 by 10.

Let's proceed to step 1:
10 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 10

Moving on to step 2:
The number 10 fits into 54 5 times, leaving a remainder of 4.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 4 after subtracting 50 from 54.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 10

Advancing to step 3:
The number 10 fits into 45 4 times, leaving a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 54.0
Subtracting 40 from 45 leaves us with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 10

Advancing to step 4:
The number 10 fits into 54 5 times, leaving a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 545.0
Subtracting 50 from 54 leaves us with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 10

Advancing to step 5:
When dividing 40 by 10, we get 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 5454.0
Subtract 40 from 40 to get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 10

Moving on to step 6:
The number 10 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 54540.0
If we subtract 0 from 9, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
The number 10 fits into 90 9 times, leaving a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 54540.9
Subtract 90 from 90 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
If we divide 0 by 10, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 54540.9
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
10 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 54540.9
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 54540.9 and a remainder of 0.0.
