78715 ÷ 77 
We're looking to find how many times 77 goes into 78715.

Moving on to step 1:
77 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 77

Going ahead to step 2:
The number 77 fits into 78 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 77 away from 78, we end up with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 77

Moving on to step 3:
The number 77 fits into 17 0 times, leaving a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 17 and we're left with 17.
Include the next digit (1) from the dividend after 17, then repeat: 171 / 77

Step 4:
When dividing 171 by 77, we get 2 with a remainder of 17.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
If we subtract 154 from 171, we get 17.
Fetch the next digit (5) from the dividend, attach it to 17 and continue: 175 / 77

Going ahead to step 5:
77 can be fit into 175 2 times, resulting in a remainder of 21.
Put 2 as the next digit of the answer. 
Result so far: 1022.0
Subtracting 154 from 175 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 6:
77 can be fit into 210 2 times, resulting in a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 1022.2
Deduct 154 from 210 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 7:
The number 77 fits into 560 7 times, leaving a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 1022.27
If we subtract 539 from 560, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 8:
If we divide 210 by 77, we get 2 and a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 1022.272
If we subtract 154 from 210, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 9:
560 divided by 77 is 7 with a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 1022.2727
If we subtract 539 from 560, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 10:
The number 77 fits into 210 2 times, leaving a remainder of 56.
The next digit of our result is 2. 
Result so far: 1022.27272
Deduct 154 from 210 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 11:
77 can be fit into 560 7 times, resulting in a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 1022.272727
Deduct 539 from 560 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 12:
210 divided by 77 is 2 with a remainder of 56.
Record the quotient 2 as the next digit in the result. 
Result so far: 1022.2727272
The remainder is 56 after subtracting 154 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 13:
The number 77 fits into 560 7 times, leaving a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 1022.27272727
If we subtract 539 from 560, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The quotient of the division is 1022.27272727, and the remainder is 2.1e-08.
