85981706 ÷ 2 
Our goal is to divide 85981706 by 2.

Advancing to step 1:
8 divided by 2 is 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 0 after subtracting 8 from 8.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 2

Advancing to step 2:
2 can be fit into 5 2 times, resulting in a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
If we take 4 away from 5, we end up with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 2

On to step 3:
2 goes into 19 9 times with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 429.0
Deduct 18 from 19 and we're left with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 2

Step 4:
If we divide 18 by 2, we get 9 and a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 4299.0
If we take 18 away from 18, we end up with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 2

Let's proceed to step 5:
2 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 42990.0
If we take 0 away from 1, we end up with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 2

Going ahead to step 6:
17 divided by 2 is 8 with a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 429908.0
Subtracting 16 from 17 leaves us with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 2

Step 7:
If we divide 10 by 2, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 4299085.0
The remainder is 0 after subtracting 10 from 10.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 2

Step 8:
6 divided by 2 is 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 42990853.0
If we subtract 6 from 6, we get 0.
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 9:
0 divided by 2 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 42990853.0
The remainder is 0 after subtracting 0 from 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 10:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 42990853.0
If we subtract 0 from 0, we get 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 42990853.0 with a balance of 0.0.
