We're dividing 65646645 by 1 
Our goal is to divide 65646645 by 1.

Advancing to step 1:
6 divided by 1 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 6 from 6 leaves us with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 1

On to step 2:
5 divided by 1 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 65.0
Deduct 5 from 5 and we're left with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 1

On to step 3:
The number 1 fits into 6 6 times, leaving a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 656.0
Subtracting 6 from 6 leaves us with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 1

Let's proceed to step 4:
4 divided by 1 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 6564.0
If we take 4 away from 4, we end up with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 1

Advancing to step 5:
1 goes into 6 6 times with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 65646.0
The remainder is 0 after subtracting 6 from 6.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 1

Advancing to step 6:
6 divided by 1 is 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 656466.0
Subtract 6 from 6 to get 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 1

Advancing to step 7:
If we divide 4 by 1, we get 4 and a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 6564664.0
If we subtract 4 from 4, we get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 1

On to step 8:
When dividing 5 by 1, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 65646645.0
If we take 5 away from 5, 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.

Advancing to step 9:
If we divide 0 by 1, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 65646645.0
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.

Going ahead to step 10:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 65646645.0
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.

The final result is 65646645.0 with a remainder of 0.0.
