The remainder is 5 after subtracting 78 from 83.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 13

On to step 4:
13 can be fit into 54 4 times, resulting in a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 664.0
If we take 52 away from 54, we end up with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 13

Going ahead to step 5:
The number 13 fits into 25 1 times, leaving a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 6641.0
If we take 13 away from 25, we end up with 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 13

On to step 6:
13 goes into 128 9 times with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 66419.0
If we take 117 away from 128, we end up with 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 13

Step 7:
13 can be fit into 112 8 times, resulting in a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 664198.0
Subtract 104 from 112 to get 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 13

Advancing to step 8:
When dividing 89 by 13, we get 6 with a remainder of 11.
Record the quotient 6 as the next digit in the result. 
Result so far: 6641986.0
If we subtract 78 from 89, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 9:
The number 13 fits into 110 8 times, leaving a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 6641986.8
The remainder is 6 after subtracting 104 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
60 divided by 13 is 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 6641986.84
If we subtract 52 from 60, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
The number 13 fits into 80 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 6641986.846
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 12:
13 goes into 20 1 times with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 6641986.8461
If we subtract 13 from 20, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 13:
13 can be fit into 70 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 6641986.84615
If we take 65 away from 70, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 14:
13 can be fit into 50 3 times, resulting in a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 6641986.846153
If we subtract 39 from 50, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 15:
If we divide 110 by 13, we get 8 and a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 6641986.8461538
If we take 104 away from 110, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 16:
13 can be fit into 60 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 6641986.84615384
Subtract 52 from 60 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 6641986.84615384 with a balance of 8e-09.
