85209657 divided by 8 
Our goal is to divide 85209657 by 8.

Let's proceed to step 1:
8 divided by 8 is 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 8 from 8 and we're left with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 8

On to step 2:
The number 8 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 5 to get 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 8

Moving on to step 3:
The number 8 fits into 52 6 times, leaving a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 106.0
Subtract 48 from 52 to get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 8

Moving on to step 4:
If we divide 40 by 8, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 1065.0
Subtract 40 from 40 to get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 8

Step 5:
8 can be fit into 9 1 times, resulting in a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 10651.0
If we subtract 8 from 9, we get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 8

Let's proceed to step 6:
If we divide 16 by 8, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 106512.0
Subtract 16 from 16 to get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 8

Advancing to step 7:
8 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 1065120.0
If we take 0 away from 5, we end up with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 8

Let's proceed to step 8:
57 divided by 8 is 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 10651207.0
The remainder is 1 after subtracting 56 from 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 9:
If we divide 10 by 8, we get 1 and a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 10651207.1
If we subtract 8 from 10, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
8 can be fit into 20 2 times, resulting in a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 10651207.12
If we take 16 away from 20, we end up 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.

Advancing to step 11:
If we divide 40 by 8, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 10651207.125
The remainder is 0 after subtracting 40 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 12:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10651207.125
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 13:
8 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 10651207.125
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 10651207.125 with a balance of 0.0.
