Fetch the next digit (2) from the dividend, attach it to 749 and continue: 7492 / 780

Advancing to step 4:
When dividing 7492 by 780, we get 9 with a remainder of 472.
The next digit of our result is 9. 
Result so far: 9.0
If we take 7020 away from 7492, we end up with 472.
Take the next digit (5) from the dividend and append it to 472, then repeat: 4725 / 780

Moving on to step 5:
780 goes into 4725 6 times with a remainder of 45.
The number 6 becomes the next digit in our result. 
Result so far: 96.0
Deduct 4680 from 4725 and we're left with 45.
Grab the next digit (1) from the dividend, add it to 45, then carry on: 451 / 780

Moving on to step 6:
When dividing 451 by 780, we get 0 with a remainder of 451.
Use 0 as the next digit of our solution. 
Result so far: 960.0
The remainder is 451 after subtracting 0 from 451.
Take the next digit (3) from the dividend and append it to 451, then repeat: 4513 / 780

On to step 7:
The number 780 fits into 4513 5 times, leaving a remainder of 613.
Use 5 as the next digit of our solution. 
Result so far: 9605.0
The remainder is 613 after subtracting 3900 from 4513.
Fetch the next digit (9) from the dividend, attach it to 613 and continue: 6139 / 780

Step 8:
When dividing 6139 by 780, we get 7 with a remainder of 679.
Write down 7 as next digit of the result. 
Result so far: 96057.0
Subtracting 5460 from 6139 leaves us with 679.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6790, and continue the process.

Step 9:
780 can be fit into 6790 8 times, resulting in a remainder of 550.
Write down 8 as next digit of the result. 
Result so far: 96057.8
The remainder is 550 after subtracting 6240 from 6790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Moving on to step 10:
780 can be fit into 5500 7 times, resulting in a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 96057.87
Subtract 5460 from 5500 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
780 goes into 400 0 times with a remainder of 400.
The next digit of our result is 0. 
Result so far: 96057.87
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 12:
The number 780 fits into 4000 5 times, leaving a remainder of 100.
Use 5 as the next digit of our solution. 
Result so far: 96057.8705
Subtracting 3900 from 4000 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 13:
780 can be fit into 1000 1 times, resulting in a remainder of 220.
Use 1 as the next digit of our solution. 
Result so far: 96057.87051
The remainder is 220 after subtracting 780 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 14:
The number 780 fits into 2200 2 times, leaving a remainder of 640.
The number 2 becomes the next digit in our result. 
Result so far: 96057.870512
If we subtract 1560 from 2200, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Going ahead to step 15:
6400 divided by 780 is 8 with a remainder of 160.
Put 8 as the next digit of the answer. 
Result so far: 96057.8705128
Deduct 6240 from 6400 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 16:
780 can be fit into 1600 2 times, resulting in a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 96057.87051282
If we subtract 1560 from 1600, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 96057.87051282 with a remaining 4e-08.
