We divide 16169405 by 528
The aim is to understand the frequency of 528 in 16169405.

Going ahead to step 1:
1 divided by 528 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 528

Step 2:
528 can be fit into 16 0 times, resulting in a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Fetch the next digit (1) from the dividend, attach it to 16 and continue: 161 / 528

Step 3:
528 can be fit into 161 0 times, resulting in a remainder of 161.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 161, we get 161.
Include the next digit (6) from the dividend after 161, then repeat: 1616 / 528

Advancing to step 4:
1616 divided by 528 is 3 with a remainder of 32.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 1584 from 1616 to get 32.
Grab the next digit (9) from the dividend, add it to 32, then carry on: 329 / 528

On to step 5:
528 goes into 329 0 times with a remainder of 329.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
Subtract 0 from 329 to get 329.
Grab the next digit (4) from the dividend, add it to 329, then carry on: 3294 / 528

On to step 6:
3294 divided by 528 is 6 with a remainder of 126.
Put 6 as the next digit of the answer. 
Result so far: 306.0
Subtracting 3168 from 3294 leaves us with 126.
Take the next digit (0) from the dividend and append it to 126, then repeat: 1260 / 528

Advancing to step 7:
The number 528 fits into 1260 2 times, leaving a remainder of 204.
Record the quotient 2 as the next digit in the result. 
Result so far: 3062.0
If we subtract 1056 from 1260, we get 204.
Append the next digit (5) from the dividend to 204 and continue with: 2045 / 528

Moving on to step 8:
528 can be fit into 2045 3 times, resulting in a remainder of 461.
Write down 3 as next digit of the result. 
Result so far: 30623.0
Deduct 1584 from 2045 and we're left with 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

Moving on to step 9:
The number 528 fits into 4610 8 times, leaving a remainder of 386.
Use 8 as the next digit of our solution. 
Result so far: 30623.8
If we subtract 4224 from 4610, we get 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Going ahead to step 10:
The number 528 fits into 3860 7 times, leaving a remainder of 164.
Record the quotient 7 as the next digit in the result. 
Result so far: 30623.87
If we subtract 3696 from 3860, we get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Advancing to step 11:
528 can be fit into 1640 3 times, resulting in a remainder of 56.
Put 3 as the next digit of the answer. 
Result so far: 30623.873
If we subtract 1584 from 1640, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 12:
528 goes into 560 1 times with a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 30623.8731
If we subtract 528 from 560, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 13:
528 can be fit into 320 0 times, resulting in a remainder of 320.
Record the quotient 0 as the next digit in the result. 
Result so far: 30623.8731
If we take 0 away from 320, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 14:
The number 528 fits into 3200 6 times, leaving a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 30623.873106
If we subtract 3168 from 3200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 15:
320 divided by 528 is 0 with a remainder of 320.
The next digit of our result is 0. 
Result so far: 30623.873106
Subtract 0 from 320 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 16:
3200 divided by 528 is 6 with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 30623.87310606
If we subtract 3168 from 3200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 30623.87310606 and a remainder of 3.2e-08.
