Let's divide 90499043 by 528
The aim is to understand the frequency of 528 in 90499043.

On to step 1:
If we divide 9 by 528, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 528

Step 2:
When dividing 90 by 528, we get 0 with a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Include the next digit (4) from the dividend after 90, then repeat: 904 / 528

Step 3:
528 can be fit into 904 1 times, resulting in a remainder of 376.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 528 from 904 leaves us with 376.
Bring next digit (9) of the dividend behind the 376 and repeat the process: 3769 / 528

Advancing to step 4:
If we divide 3769 by 528, we get 7 and a remainder of 73.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we take 3696 away from 3769, we end up with 73.
Grab the next digit (9) from the dividend, add it to 73, then carry on: 739 / 528

Advancing to step 5:
The number 528 fits into 739 1 times, leaving a remainder of 211.
The number 1 becomes the next digit in our result. 
Result so far: 171.0
The remainder is 211 after subtracting 528 from 739.
Grab the next digit (0) from the dividend, add it to 211, then carry on: 2110 / 528

Let's proceed to step 6:
When dividing 2110 by 528, we get 3 with a remainder of 526.
Use 3 as the next digit of our solution. 
Result so far: 1713.0
The remainder is 526 after subtracting 1584 from 2110.
Fetch the next digit (4) from the dividend, attach it to 526 and continue: 5264 / 528

Let's proceed to step 7:
When dividing 5264 by 528, we get 9 with a remainder of 512.
The next digit of our result is 9. 
Result so far: 17139.0
Deduct 4752 from 5264 and we're left with 512.
Append the next digit (3) from the dividend to 512 and continue with: 5123 / 528

Moving on to step 8:
If we divide 5123 by 528, we get 9 and a remainder of 371.
Record the quotient 9 as the next digit in the result. 
Result so far: 171399.0
Deduct 4752 from 5123 and we're left with 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Going ahead to step 9:
When dividing 3710 by 528, we get 7 with a remainder of 14.
The next digit of our result is 7. 
Result so far: 171399.7
The remainder is 14 after subtracting 3696 from 3710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 10:
140 divided by 528 is 0 with a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 171399.7
The remainder is 140 after subtracting 0 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 11:
When dividing 1400 by 528, we get 2 with a remainder of 344.
Use 2 as the next digit of our solution. 
Result so far: 171399.702
If we subtract 1056 from 1400, we get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

On to step 12:
The number 528 fits into 3440 6 times, leaving a remainder of 272.
The number 6 becomes the next digit in our result. 
Result so far: 171399.7026
The remainder is 272 after subtracting 3168 from 3440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Moving on to step 13:
528 can be fit into 2720 5 times, resulting in a remainder of 80.
Write down 5 as next digit of the result. 
Result so far: 171399.70265
If we subtract 2640 from 2720, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 14:
If we divide 800 by 528, we get 1 and a remainder of 272.
The next digit of our result is 1. 
Result so far: 171399.702651
Deduct 528 from 800 and we're left with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Let's proceed to step 15:
528 goes into 2720 5 times with a remainder of 80.
Put 5 as the next digit of the answer. 
Result so far: 171399.7026515
Subtract 2640 from 2720 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 16:
800 divided by 528 is 1 with a remainder of 272.
Put 1 as the next digit of the answer. 
Result so far: 171399.70265151
If we take 528 away from 800, we end up with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

After the division, we end up with 171399.70265151 and a remainder of 2.72e-07.
