We're dividing 43157242 by 528 
We want to divide 43157242 by 528.

Advancing to step 1:
When dividing 4 by 528, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 528

Moving on to step 2:
The number 528 fits into 43 0 times, leaving a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Fetch the next digit (1) from the dividend, attach it to 43 and continue: 431 / 528

On to step 3:
528 can be fit into 431 0 times, resulting in a remainder of 431.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 431 after subtracting 0 from 431.
Take the next digit (5) from the dividend and append it to 431, then repeat: 4315 / 528

On to step 4:
The number 528 fits into 4315 8 times, leaving a remainder of 91.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 4224 from 4315 leaves us with 91.
Bring next digit (7) of the dividend behind the 91 and repeat the process: 917 / 528

Advancing to step 5:
The number 528 fits into 917 1 times, leaving a remainder of 389.
Put 1 as the next digit of the answer. 
Result so far: 81.0
Subtract 528 from 917 to get 389.
Fetch the next digit (2) from the dividend, attach it to 389 and continue: 3892 / 528

Moving on to step 6:
3892 divided by 528 is 7 with a remainder of 196.
Put 7 as the next digit of the answer. 
Result so far: 817.0
The remainder is 196 after subtracting 3696 from 3892.
Grab the next digit (4) from the dividend, add it to 196, then carry on: 1964 / 528

Let's proceed to step 7:
528 can be fit into 1964 3 times, resulting in a remainder of 380.
Put 3 as the next digit of the answer. 
Result so far: 8173.0
Deduct 1584 from 1964 and we're left with 380.
Include the next digit (2) from the dividend after 380, then repeat: 3802 / 528

Advancing to step 8:
3802 divided by 528 is 7 with a remainder of 106.
The number 7 becomes the next digit in our result. 
Result so far: 81737.0
If we take 3696 away from 3802, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Step 9:
If we divide 1060 by 528, we get 2 and a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 81737.2
Deduct 1056 from 1060 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.

Moving on to step 10:
40 divided by 528 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 81737.2
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
528 goes into 400 0 times with a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 81737.2
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final result is 81737.2 with a remainder of 0.04.
