43506813 ÷ 526 
We want to figure out the number of times 43506813 can be divided by 526.

Step 1:
If we divide 4 by 526, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 526

On to step 2:
The number 526 fits into 43 0 times, leaving a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Take the next digit (5) from the dividend and append it to 43, then repeat: 435 / 526

Let's proceed to step 3:
If we divide 435 by 526, we get 0 and a remainder of 435.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 435, we end up with 435.
Fetch the next digit (0) from the dividend, attach it to 435 and continue: 4350 / 526

Step 4:
When dividing 4350 by 526, we get 8 with a remainder of 142.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 4208 from 4350, we get 142.
Grab the next digit (6) from the dividend, add it to 142, then carry on: 1426 / 526

Step 5:
526 goes into 1426 2 times with a remainder of 374.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
If we subtract 1052 from 1426, we get 374.
Bring next digit (8) of the dividend behind the 374 and repeat the process: 3748 / 526

Going ahead to step 6:
3748 divided by 526 is 7 with a remainder of 66.
Use 7 as the next digit of our solution. 
Result so far: 827.0
Subtracting 3682 from 3748 leaves us with 66.
Append the next digit (1) from the dividend to 66 and continue with: 661 / 526

Moving on to step 7:
If we divide 661 by 526, we get 1 and a remainder of 135.
The next digit of our result is 1. 
Result so far: 8271.0
If we subtract 526 from 661, we get 135.
Include the next digit (3) from the dividend after 135, then repeat: 1353 / 526

Step 8:
526 goes into 1353 2 times with a remainder of 301.
Put 2 as the next digit of the answer. 
Result so far: 82712.0
If we subtract 1052 from 1353, we get 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Step 9:
526 can be fit into 3010 5 times, resulting in a remainder of 380.
The number 5 becomes the next digit in our result. 
Result so far: 82712.5
Deduct 2630 from 3010 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 10:
The number 526 fits into 3800 7 times, leaving a remainder of 118.
Write down 7 as next digit of the result. 
Result so far: 82712.57
The remainder is 118 after subtracting 3682 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Step 11:
526 can be fit into 1180 2 times, resulting in a remainder of 128.
The next digit of our result is 2. 
Result so far: 82712.572
Subtract 1052 from 1180 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 12:
The number 526 fits into 1280 2 times, leaving a remainder of 228.
Put 2 as the next digit of the answer. 
Result so far: 82712.5722
If we take 1052 away from 1280, we end up with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

In conclusion, the division gives 82712.5722 with a balance of 0.00228.
