1406129 ÷ 528 
The aim is to understand the frequency of 528 in 1406129.

Step 1:
When dividing 1 by 528, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 528

Let's proceed to step 2:
If we divide 14 by 528, we get 0 and a remainder of 14.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Take the next digit (0) from the dividend and append it to 14, then repeat: 140 / 528

Advancing to step 3:
140 divided by 528 is 0 with a remainder of 140.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 140 and we're left with 140.
Grab the next digit (6) from the dividend, add it to 140, then carry on: 1406 / 528

Step 4:
The number 528 fits into 1406 2 times, leaving a remainder of 350.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 1056 from 1406 to get 350.
Take the next digit (1) from the dividend and append it to 350, then repeat: 3501 / 528

Step 5:
528 goes into 3501 6 times with a remainder of 333.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
The remainder is 333 after subtracting 3168 from 3501.
Take the next digit (2) from the dividend and append it to 333, then repeat: 3332 / 528

Going ahead to step 6:
If we divide 3332 by 528, we get 6 and a remainder of 164.
Put 6 as the next digit of the answer. 
Result so far: 266.0
If we take 3168 away from 3332, we end up with 164.
Include the next digit (9) from the dividend after 164, then repeat: 1649 / 528

On to step 7:
The number 528 fits into 1649 3 times, leaving a remainder of 65.
The number 3 becomes the next digit in our result. 
Result so far: 2663.0
Subtracting 1584 from 1649 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 8:
528 can be fit into 650 1 times, resulting in a remainder of 122.
Write down 1 as next digit of the result. 
Result so far: 2663.1
If we take 528 away from 650, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Advancing to step 9:
The number 528 fits into 1220 2 times, leaving a remainder of 164.
Record the quotient 2 as the next digit in the result. 
Result so far: 2663.12
If we take 1056 away from 1220, we end up with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

On to step 10:
When dividing 1640 by 528, we get 3 with a remainder of 56.
The number 3 becomes the next digit in our result. 
Result so far: 2663.123
If we take 1584 away from 1640, we end up with 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 11:
560 divided by 528 is 1 with a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 2663.1231
Subtracting 528 from 560 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 12:
The number 528 fits into 320 0 times, leaving a remainder of 320.
The number 0 becomes the next digit in our result. 
Result so far: 2663.1231
Subtracting 0 from 320 leaves us 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 13:
The number 528 fits into 3200 6 times, leaving a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 2663.123106
If we take 3168 away from 3200, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 14:
When dividing 320 by 528, we get 0 with a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 2663.123106
If we subtract 0 from 320, we 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.

Moving on to step 15:
528 goes into 3200 6 times with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 2663.12310606
If we take 3168 away from 3200, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 2663.12310606, with a leftover of 3.2e-08.
