81350526 divided by 4 
Our goal is to divide 81350526 by 4.

Advancing to step 1:
4 can be fit into 8 2 times, resulting in a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
If we take 8 away from 8, we end up with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 4

Step 2:
If we divide 1 by 4, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Subtract 0 from 1 to get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 4

On to step 3:
If we divide 13 by 4, we get 3 and a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 203.0
Deduct 12 from 13 and we're left with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 4

On to step 4:
If we divide 15 by 4, we get 3 and a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 2033.0
The remainder is 3 after subtracting 12 from 15.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 4

Moving on to step 5:
When dividing 30 by 4, we get 7 with a remainder of 2.
The next digit of our result is 7. 
Result so far: 20337.0
If we take 28 away from 30, we end up with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 4

Moving on to step 6:
4 can be fit into 25 6 times, resulting in a remainder of 1.
The next digit of our result is 6. 
Result so far: 203376.0
The remainder is 1 after subtracting 24 from 25.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 4

Step 7:
4 can be fit into 12 3 times, resulting in a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 2033763.0
If we subtract 12 from 12, we get 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 4

Moving on to step 8:
The number 4 fits into 6 1 times, leaving a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 20337631.0
Subtracting 4 from 6 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
If we divide 20 by 4, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 20337631.5
Deduct 20 from 20 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.

Let's proceed to step 10:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 20337631.5
Subtract 0 from 0 to 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.

Step 11:
4 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 20337631.5
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 20337631.5 with a balance of 0.0.
