We're dividing 85769863 by 13 
Our goal is to divide 85769863 by 13.

Going ahead to step 1:
If we divide 8 by 13, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 13

Going ahead to step 2:
The number 13 fits into 85 6 times, leaving a remainder of 7.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 7 after subtracting 78 from 85.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 13

Let's proceed to step 3:
13 can be fit into 77 5 times, resulting in a remainder of 12.
The number 5 becomes the next digit in our result. 
Result so far: 65.0
The remainder is 12 after subtracting 65 from 77.
Fetch the next digit (6) from the dividend, attach it to 12 and continue: 126 / 13

On to step 4:
13 can be fit into 126 9 times, resulting in a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 659.0
Subtract 117 from 126 to get 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 13

On to step 5:
If we divide 99 by 13, we get 7 and a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 6597.0
If we take 91 away from 99, we end up with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 13

Advancing to step 6:
The number 13 fits into 88 6 times, leaving a remainder of 10.
The next digit of our result is 6. 
Result so far: 65976.0
Subtract 78 from 88 to get 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 13

Going ahead to step 7:
106 divided by 13 is 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 659768.0
Deduct 104 from 106 and we're left with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 13

Moving on to step 8:
If we divide 23 by 13, we get 1 and a remainder of 10.
The next digit of our result is 1. 
Result so far: 6597681.0
If we take 13 away from 23, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
13 goes into 100 7 times with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 6597681.7
Subtract 91 from 100 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 10:
If we divide 90 by 13, we get 6 and a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 6597681.76
Deduct 78 from 90 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 11:
13 can be fit into 120 9 times, resulting in a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 6597681.769
If we subtract 117 from 120, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 12:
30 divided by 13 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 6597681.7692
Deduct 26 from 30 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 13:
If we divide 40 by 13, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 6597681.76923
If we subtract 39 from 40, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 14:
The number 13 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 6597681.76923
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 15:
13 goes into 100 7 times with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 6597681.7692307
The remainder is 9 after subtracting 91 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 16:
90 divided by 13 is 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 6597681.76923076
Subtracting 78 from 90 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 6597681.76923076, with a leftover of 1.2e-08.
