Append the next digit (8) from the dividend to 7 and continue with: 78 / 780

On to step 2:
78 divided by 780 is 0 with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Include the next digit (2) from the dividend after 78, then repeat: 782 / 780

Step 3:
If we divide 782 by 780, we get 1 and a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 780 from 782 to get 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 780

On to step 4:
780 can be fit into 27 0 times, resulting in a remainder of 27.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 27, we end up with 27.
Fetch the next digit (2) from the dividend, attach it to 27 and continue: 272 / 780

On to step 5:
780 goes into 272 0 times with a remainder of 272.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
Deduct 0 from 272 and we're left with 272.
Grab the next digit (9) from the dividend, add it to 272, then carry on: 2729 / 780

Moving on to step 6:
The number 780 fits into 2729 3 times, leaving a remainder of 389.
The number 3 becomes the next digit in our result. 
Result so far: 1003.0
Subtracting 2340 from 2729 leaves us with 389.
Append the next digit (7) from the dividend to 389 and continue with: 3897 / 780

Step 7:
3897 divided by 780 is 4 with a remainder of 777.
The next digit of our result is 4. 
Result so far: 10034.0
The remainder is 777 after subtracting 3120 from 3897.
Include the next digit (0) from the dividend after 777, then repeat: 7770 / 780

Let's proceed to step 8:
When dividing 7770 by 780, we get 9 with a remainder of 750.
The number 9 becomes the next digit in our result. 
Result so far: 100349.0
Subtract 7020 from 7770 to get 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Moving on to step 9:
If we divide 7500 by 780, we get 9 and a remainder of 480.
Use 9 as the next digit of our solution. 
Result so far: 100349.9
If we take 7020 away from 7500, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 10:
The number 780 fits into 4800 6 times, leaving a remainder of 120.
Put 6 as the next digit of the answer. 
Result so far: 100349.96
Subtracting 4680 from 4800 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 11:
When dividing 1200 by 780, we get 1 with a remainder of 420.
Use 1 as the next digit of our solution. 
Result so far: 100349.961
Subtract 780 from 1200 to get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 12:
If we divide 4200 by 780, we get 5 and a remainder of 300.
Record the quotient 5 as the next digit in the result. 
Result so far: 100349.9615
Subtract 3900 from 4200 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 13:
780 goes into 3000 3 times with a remainder of 660.
Write down 3 as next digit of the result. 
Result so far: 100349.96153
If we subtract 2340 from 3000, we get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Moving on to step 14:
780 goes into 6600 8 times with a remainder of 360.
Use 8 as the next digit of our solution. 
Result so far: 100349.961538
The remainder is 360 after subtracting 6240 from 6600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 15:
The number 780 fits into 3600 4 times, leaving a remainder of 480.
Put 4 as the next digit of the answer. 
Result so far: 100349.9615384
Subtracting 3120 from 3600 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 16:
4800 divided by 780 is 6 with a remainder of 120.
Use 6 as the next digit of our solution. 
Result so far: 100349.96153846
If we take 4680 away from 4800, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The final outcome is 100349.96153846, with a leftover of 1.2e-07.
