Let's divide 77664945 by 1
Our goal is to divide 77664945 by 1.

Advancing to step 1:
The number 1 fits into 7 7 times, leaving a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 7 from 7 to get 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 1

Advancing to step 2:
1 goes into 7 7 times with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 77.0
The remainder is 0 after subtracting 7 from 7.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 1

Advancing to step 3:
When dividing 6 by 1, we get 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 776.0
If we take 6 away from 6, we end up with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 1

Going ahead to step 4:
The number 1 fits into 6 6 times, leaving a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 7766.0
If we take 6 away from 6, we end up with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 1

On to step 5:
4 divided by 1 is 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 77664.0
If we subtract 4 from 4, we get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 1

Let's proceed to step 6:
When dividing 9 by 1, we get 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 776649.0
The remainder is 0 after subtracting 9 from 9.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 1

On to step 7:
If we divide 4 by 1, we get 4 and a remainder of 0.
The next digit of our result is 4. 
Result so far: 7766494.0
If we take 4 away from 4, we end up with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 1

Advancing to step 8:
5 divided by 1 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 77664945.0
If we subtract 5 from 5, 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.

Going ahead to step 9:
1 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 77664945.0
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.

Step 10:
If we divide 0 by 1, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 77664945.0
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.

The quotient of the division is 77664945.0, and the remainder is 0.0.
