783015 ÷ 77 
We want to figure out the number of times 783015 can be divided by 77.

On to step 1:
When dividing 7 by 77, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 77

Moving on to step 2:
When dividing 78 by 77, we get 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 77 away from 78, we end up with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 77

Step 3:
13 divided by 77 is 0 with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 13 to get 13.
Include the next digit (0) from the dividend after 13, then repeat: 130 / 77

Step 4:
The number 77 fits into 130 1 times, leaving a remainder of 53.
The next digit of our result is 1. 
Result so far: 101.0
Deduct 77 from 130 and we're left with 53.
Append the next digit (1) from the dividend to 53 and continue with: 531 / 77

Moving on to step 5:
When dividing 531 by 77, we get 6 with a remainder of 69.
Use 6 as the next digit of our solution. 
Result so far: 1016.0
If we take 462 away from 531, we end up with 69.
Grab the next digit (5) from the dividend, add it to 69, then carry on: 695 / 77

Let's proceed to step 6:
695 divided by 77 is 9 with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 10169.0
Subtract 693 from 695 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
The number 77 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 10169.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
The number 77 fits into 200 2 times, leaving a remainder of 46.
Use 2 as the next digit of our solution. 
Result so far: 10169.02
If we subtract 154 from 200, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 9:
77 can be fit into 460 5 times, resulting in a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 10169.025
The remainder is 75 after subtracting 385 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 10:
The number 77 fits into 750 9 times, leaving a remainder of 57.
The number 9 becomes the next digit in our result. 
Result so far: 10169.0259
Subtracting 693 from 750 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 11:
77 goes into 570 7 times with a remainder of 31.
The next digit of our result is 7. 
Result so far: 10169.02597
If we take 539 away from 570, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 12:
77 can be fit into 310 4 times, resulting in a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 10169.025974
Deduct 308 from 310 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 13:
77 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 10169.025974
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 14:
The number 77 fits into 200 2 times, leaving a remainder of 46.
Record the quotient 2 as the next digit in the result. 
Result so far: 10169.02597402
The remainder is 46 after subtracting 154 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Our division results in 10169.02597402 with a remaining 4.6e-08.
