Let's divide 64554209 by 10
We want to divide 64554209 by 10.

Step 1:
The number 10 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 10

Step 2:
When dividing 64 by 10, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 4 after subtracting 60 from 64.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 10

Step 3:
10 can be fit into 45 4 times, resulting in a remainder of 5.
The next digit of our result is 4. 
Result so far: 64.0
Subtracting 40 from 45 leaves us with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 10

Advancing to step 4:
10 can be fit into 55 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 645.0
Deduct 50 from 55 and we're left with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 10

Step 5:
When dividing 54 by 10, we get 5 with a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 6455.0
Subtracting 50 from 54 leaves us with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 10

On to step 6:
10 can be fit into 42 4 times, resulting in a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 64554.0
If we subtract 40 from 42, we get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 10

On to step 7:
When dividing 20 by 10, we get 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 645542.0
Subtracting 20 from 20 leaves us with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 10

Step 8:
10 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 6455420.0
Deduct 0 from 9 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 9:
The number 10 fits into 90 9 times, leaving a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 6455420.9
If we subtract 90 from 90, we 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 10:
10 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 6455420.9
If we subtract 0 from 0, we 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.

Moving on to step 11:
When dividing 0 by 10, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 6455420.9
The remainder is 0 after subtracting 0 from 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 6455420.9 and a remainder of 0.0.
