Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 778

Let's proceed to step 2:
When dividing 13 by 778, we get 0 with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Fetch the next digit (2) from the dividend, attach it to 13 and continue: 132 / 778

Going ahead to step 3:
778 can be fit into 132 0 times, resulting in a remainder of 132.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 132 after subtracting 0 from 132.
Grab the next digit (8) from the dividend, add it to 132, then carry on: 1328 / 778

Moving on to step 4:
1328 divided by 778 is 1 with a remainder of 550.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 778 from 1328 to get 550.
Take the next digit (0) from the dividend and append it to 550, then repeat: 5500 / 778

Step 5:
778 can be fit into 5500 7 times, resulting in a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtracting 5446 from 5500 leaves us with 54.
Grab the next digit (6) from the dividend, add it to 54, then carry on: 546 / 778

Step 6:
546 divided by 778 is 0 with a remainder of 546.
The next digit of our result is 0. 
Result so far: 170.0
If we take 0 away from 546, we end up with 546.
Include the next digit (4) from the dividend after 546, then repeat: 5464 / 778

Let's proceed to step 7:
The number 778 fits into 5464 7 times, leaving a remainder of 18.
The next digit of our result is 7. 
Result so far: 1707.0
Subtracting 5446 from 5464 leaves us with 18.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 778

Advancing to step 8:
187 divided by 778 is 0 with a remainder of 187.
The next digit of our result is 0. 
Result so far: 17070.0
Deduct 0 from 187 and we're left with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Step 9:
When dividing 1870 by 778, we get 2 with a remainder of 314.
Put 2 as the next digit of the answer. 
Result so far: 17070.2
The remainder is 314 after subtracting 1556 from 1870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

On to step 10:
778 goes into 3140 4 times with a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 17070.24
If we subtract 3112 from 3140, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 11:
778 goes into 280 0 times with a remainder of 280.
Use 0 as the next digit of our solution. 
Result so far: 17070.24
Subtract 0 from 280 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 12:
The number 778 fits into 2800 3 times, leaving a remainder of 466.
The next digit of our result is 3. 
Result so far: 17070.2403
Subtracting 2334 from 2800 leaves us with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

On to step 13:
When dividing 4660 by 778, we get 5 with a remainder of 770.
Put 5 as the next digit of the answer. 
Result so far: 17070.24035
If we take 3890 away from 4660, we end up with 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

On to step 14:
778 can be fit into 7700 9 times, resulting in a remainder of 698.
Put 9 as the next digit of the answer. 
Result so far: 17070.240359
If we subtract 7002 from 7700, we get 698.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6980, and continue the process.

Let's proceed to step 15:
778 can be fit into 6980 8 times, resulting in a remainder of 756.
The number 8 becomes the next digit in our result. 
Result so far: 17070.2403598
If we take 6224 away from 6980, we end up with 756.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7560, and continue the process.

On to step 16:
When dividing 7560 by 778, we get 9 with a remainder of 558.
Write down 9 as next digit of the result. 
Result so far: 17070.24035989
Subtracting 7002 from 7560 leaves us with 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

In conclusion, the division gives 17070.24035989 with a balance of 5.58e-07.
