42047839 divided by 528 
The aim is to understand the frequency of 528 in 42047839.

On to step 1:
If we divide 4 by 528, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 528

Step 2:
The number 528 fits into 42 0 times, leaving a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Take the next digit (0) from the dividend and append it to 42, then repeat: 420 / 528

Going ahead to step 3:
528 goes into 420 0 times with a remainder of 420.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 420, we get 420.
Bring next digit (4) of the dividend behind the 420 and repeat the process: 4204 / 528

On to step 4:
When dividing 4204 by 528, we get 7 with a remainder of 508.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 3696 from 4204 leaves us with 508.
Append the next digit (7) from the dividend to 508 and continue with: 5087 / 528

Step 5:
528 can be fit into 5087 9 times, resulting in a remainder of 335.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
The remainder is 335 after subtracting 4752 from 5087.
Append the next digit (8) from the dividend to 335 and continue with: 3358 / 528

Step 6:
The number 528 fits into 3358 6 times, leaving a remainder of 190.
The next digit of our result is 6. 
Result so far: 796.0
If we take 3168 away from 3358, we end up with 190.
Include the next digit (3) from the dividend after 190, then repeat: 1903 / 528

Let's proceed to step 7:
If we divide 1903 by 528, we get 3 and a remainder of 319.
Write down 3 as next digit of the result. 
Result so far: 7963.0
If we subtract 1584 from 1903, we get 319.
Include the next digit (9) from the dividend after 319, then repeat: 3199 / 528

Let's proceed to step 8:
528 goes into 3199 6 times with a remainder of 31.
The number 6 becomes the next digit in our result. 
Result so far: 79636.0
The remainder is 31 after subtracting 3168 from 3199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 9:
528 can be fit into 310 0 times, resulting in a remainder of 310.
The next digit of our result is 0. 
Result so far: 79636.0
Subtract 0 from 310 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

On to step 10:
528 can be fit into 3100 5 times, resulting in a remainder of 460.
Record the quotient 5 as the next digit in the result. 
Result so far: 79636.05
Subtracting 2640 from 3100 leaves us with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Advancing to step 11:
528 can be fit into 4600 8 times, resulting in a remainder of 376.
Record the quotient 8 as the next digit in the result. 
Result so far: 79636.058
Subtract 4224 from 4600 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

On to step 12:
528 can be fit into 3760 7 times, resulting in a remainder of 64.
Put 7 as the next digit of the answer. 
Result so far: 79636.0587
Deduct 3696 from 3760 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 13:
640 divided by 528 is 1 with a remainder of 112.
Use 1 as the next digit of our solution. 
Result so far: 79636.05871
If we take 528 away from 640, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 14:
528 goes into 1120 2 times with a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 79636.058712
Subtracting 1056 from 1120 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 15:
If we divide 640 by 528, we get 1 and a remainder of 112.
The next digit of our result is 1. 
Result so far: 79636.0587121
Subtract 528 from 640 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 16:
528 goes into 1120 2 times with a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 79636.05871212
If we subtract 1056 from 1120, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

In conclusion, the division gives 79636.05871212 with a balance of 6.4e-08.
