We're dividing 43697536 by 528 
The aim is to understand the frequency of 528 in 43697536.

Going ahead to step 1:
When dividing 4 by 528, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 528

Advancing 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
The remainder is 43 after subtracting 0 from 43.
Grab the next digit (6) from the dividend, add it to 43, then carry on: 436 / 528

Advancing to step 3:
If we divide 436 by 528, we get 0 and a remainder of 436.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 436 after subtracting 0 from 436.
Append the next digit (9) from the dividend to 436 and continue with: 4369 / 528

Step 4:
4369 divided by 528 is 8 with a remainder of 145.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 4224 from 4369 and we're left with 145.
Take the next digit (7) from the dividend and append it to 145, then repeat: 1457 / 528

Step 5:
When dividing 1457 by 528, we get 2 with a remainder of 401.
Use 2 as the next digit of our solution. 
Result so far: 82.0
Deduct 1056 from 1457 and we're left with 401.
Append the next digit (5) from the dividend to 401 and continue with: 4015 / 528

Let's proceed to step 6:
4015 divided by 528 is 7 with a remainder of 319.
Write down 7 as next digit of the result. 
Result so far: 827.0
Subtract 3696 from 4015 to get 319.
Include the next digit (3) from the dividend after 319, then repeat: 3193 / 528

On to step 7:
528 can be fit into 3193 6 times, resulting in a remainder of 25.
Put 6 as the next digit of the answer. 
Result so far: 8276.0
Deduct 3168 from 3193 and we're left with 25.
Append the next digit (6) from the dividend to 25 and continue with: 256 / 528

Step 8:
The number 528 fits into 256 0 times, leaving a remainder of 256.
Use 0 as the next digit of our solution. 
Result so far: 82760.0
If we take 0 away from 256, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 9:
If we divide 2560 by 528, we get 4 and a remainder of 448.
Write down 4 as next digit of the result. 
Result so far: 82760.4
Subtracting 2112 from 2560 leaves us with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

On to step 10:
When dividing 4480 by 528, we get 8 with a remainder of 256.
Record the quotient 8 as the next digit in the result. 
Result so far: 82760.48
If we take 4224 away from 4480, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 11:
When dividing 2560 by 528, we get 4 with a remainder of 448.
The next digit of our result is 4. 
Result so far: 82760.484
Subtract 2112 from 2560 to get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Let's proceed to step 12:
528 can be fit into 4480 8 times, resulting in a remainder of 256.
Record the quotient 8 as the next digit in the result. 
Result so far: 82760.4848
If we subtract 4224 from 4480, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Advancing to step 13:
2560 divided by 528 is 4 with a remainder of 448.
The next digit of our result is 4. 
Result so far: 82760.48484
Subtracting 2112 from 2560 leaves us with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Step 14:
528 goes into 4480 8 times with a remainder of 256.
The number 8 becomes the next digit in our result. 
Result so far: 82760.484848
The remainder is 256 after subtracting 4224 from 4480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 15:
528 can be fit into 2560 4 times, resulting in a remainder of 448.
Record the quotient 4 as the next digit in the result. 
Result so far: 82760.4848484
If we subtract 2112 from 2560, we get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Going ahead to step 16:
4480 divided by 528 is 8 with a remainder of 256.
Use 8 as the next digit of our solution. 
Result so far: 82760.48484848
The remainder is 256 after subtracting 4224 from 4480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

The final outcome is 82760.48484848, with a leftover of 2.56e-07.
