We're dividing 16371951 by 528 
The aim is to understand the frequency of 528 in 16371951.

On to step 1:
528 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 528

Step 2:
16 divided by 528 is 0 with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Fetch the next digit (3) from the dividend, attach it to 16 and continue: 163 / 528

Let's proceed to step 3:
528 can be fit into 163 0 times, resulting in a remainder of 163.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 163 to get 163.
Grab the next digit (7) from the dividend, add it to 163, then carry on: 1637 / 528

Advancing to step 4:
If we divide 1637 by 528, we get 3 and a remainder of 53.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 1584 from 1637 leaves us with 53.
Fetch the next digit (1) from the dividend, attach it to 53 and continue: 531 / 528

Moving on to step 5:
If we divide 531 by 528, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Subtracting 528 from 531 leaves us with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 528

Going ahead to step 6:
39 divided by 528 is 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 310.0
Subtracting 0 from 39 leaves us with 39.
Append the next digit (5) from the dividend to 39 and continue with: 395 / 528

Moving on to step 7:
528 goes into 395 0 times with a remainder of 395.
Record the quotient 0 as the next digit in the result. 
Result so far: 3100.0
Subtract 0 from 395 to get 395.
Include the next digit (1) from the dividend after 395, then repeat: 3951 / 528

On to step 8:
3951 divided by 528 is 7 with a remainder of 255.
The number 7 becomes the next digit in our result. 
Result so far: 31007.0
The remainder is 255 after subtracting 3696 from 3951.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

On to step 9:
2550 divided by 528 is 4 with a remainder of 438.
Put 4 as the next digit of the answer. 
Result so far: 31007.4
Subtracting 2112 from 2550 leaves us with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Advancing to step 10:
When dividing 4380 by 528, we get 8 with a remainder of 156.
Write down 8 as next digit of the result. 
Result so far: 31007.48
If we subtract 4224 from 4380, we get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Going ahead to step 11:
528 can be fit into 1560 2 times, resulting in a remainder of 504.
Record the quotient 2 as the next digit in the result. 
Result so far: 31007.482
If we take 1056 away from 1560, we end up with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Let's proceed to step 12:
The number 528 fits into 5040 9 times, leaving a remainder of 288.
The next digit of our result is 9. 
Result so far: 31007.4829
Subtracting 4752 from 5040 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Step 13:
528 goes into 2880 5 times with a remainder of 240.
Use 5 as the next digit of our solution. 
Result so far: 31007.48295
If we subtract 2640 from 2880, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 14:
528 can be fit into 2400 4 times, resulting in a remainder of 288.
Put 4 as the next digit of the answer. 
Result so far: 31007.482954
If we subtract 2112 from 2400, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Moving on to step 15:
528 goes into 2880 5 times with a remainder of 240.
Put 5 as the next digit of the answer. 
Result so far: 31007.4829545
Subtract 2640 from 2880 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 16:
528 can be fit into 2400 4 times, resulting in a remainder of 288.
Write down 4 as next digit of the result. 
Result so far: 31007.48295454
The remainder is 288 after subtracting 2112 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Our division results in 31007.48295454 with a remaining 2.88e-07.
