We divide 83993337 by 528
The aim is to understand the frequency of 528 in 83993337.

Advancing to step 1:
8 divided by 528 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 528

Going ahead to step 2:
The number 528 fits into 83 0 times, leaving a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 83 to get 83.
Include the next digit (9) from the dividend after 83, then repeat: 839 / 528

Step 3:
839 divided by 528 is 1 with a remainder of 311.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 528 from 839 to get 311.
Fetch the next digit (9) from the dividend, attach it to 311 and continue: 3119 / 528

On to step 4:
528 goes into 3119 5 times with a remainder of 479.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 2640 from 3119 and we're left with 479.
Grab the next digit (3) from the dividend, add it to 479, then carry on: 4793 / 528

Let's proceed to step 5:
If we divide 4793 by 528, we get 9 and a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 159.0
If we take 4752 away from 4793, we end up with 41.
Bring next digit (3) of the dividend behind the 41 and repeat the process: 413 / 528

Let's proceed to step 6:
413 divided by 528 is 0 with a remainder of 413.
The number 0 becomes the next digit in our result. 
Result so far: 1590.0
Deduct 0 from 413 and we're left with 413.
Fetch the next digit (3) from the dividend, attach it to 413 and continue: 4133 / 528

Step 7:
528 can be fit into 4133 7 times, resulting in a remainder of 437.
Use 7 as the next digit of our solution. 
Result so far: 15907.0
If we subtract 3696 from 4133, we get 437.
Bring next digit (7) of the dividend behind the 437 and repeat the process: 4377 / 528

On to step 8:
528 can be fit into 4377 8 times, resulting in a remainder of 153.
The next digit of our result is 8. 
Result so far: 159078.0
Subtracting 4224 from 4377 leaves us with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Let's proceed to step 9:
528 goes into 1530 2 times with a remainder of 474.
Use 2 as the next digit of our solution. 
Result so far: 159078.2
If we take 1056 away from 1530, we end up with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Moving on to step 10:
528 can be fit into 4740 8 times, resulting in a remainder of 516.
Write down 8 as next digit of the result. 
Result so far: 159078.28
Deduct 4224 from 4740 and we're left with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Advancing to step 11:
If we divide 5160 by 528, we get 9 and a remainder of 408.
Put 9 as the next digit of the answer. 
Result so far: 159078.289
Subtracting 4752 from 5160 leaves us with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Advancing to step 12:
When dividing 4080 by 528, we get 7 with a remainder of 384.
The next digit of our result is 7. 
Result so far: 159078.2897
Deduct 3696 from 4080 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Let's proceed to step 13:
3840 divided by 528 is 7 with a remainder of 144.
The next digit of our result is 7. 
Result so far: 159078.28977
Subtract 3696 from 3840 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

In conclusion, the division gives 159078.28977 with a balance of 0.000144.
