We're dividing 73171883 by 528 
The aim is to understand the frequency of 528 in 73171883.

On to step 1:
When dividing 7 by 528, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 528

Step 2:
528 can be fit into 73 0 times, resulting in a remainder of 73.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Take the next digit (1) from the dividend and append it to 73, then repeat: 731 / 528

Going ahead to step 3:
731 divided by 528 is 1 with a remainder of 203.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 528 from 731 to get 203.
Append the next digit (7) from the dividend to 203 and continue with: 2037 / 528

On to step 4:
If we divide 2037 by 528, we get 3 and a remainder of 453.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 1584 from 2037 and we're left with 453.
Take the next digit (1) from the dividend and append it to 453, then repeat: 4531 / 528

Step 5:
When dividing 4531 by 528, we get 8 with a remainder of 307.
Write down 8 as next digit of the result. 
Result so far: 138.0
If we take 4224 away from 4531, we end up with 307.
Fetch the next digit (8) from the dividend, attach it to 307 and continue: 3078 / 528

Going ahead to step 6:
528 goes into 3078 5 times with a remainder of 438.
The number 5 becomes the next digit in our result. 
Result so far: 1385.0
If we take 2640 away from 3078, we end up with 438.
Take the next digit (8) from the dividend and append it to 438, then repeat: 4388 / 528

On to step 7:
If we divide 4388 by 528, we get 8 and a remainder of 164.
The next digit of our result is 8. 
Result so far: 13858.0
If we subtract 4224 from 4388, we get 164.
Include the next digit (3) from the dividend after 164, then repeat: 1643 / 528

Advancing to step 8:
When dividing 1643 by 528, we get 3 with a remainder of 59.
The number 3 becomes the next digit in our result. 
Result so far: 138583.0
Subtracting 1584 from 1643 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 9:
The number 528 fits into 590 1 times, leaving a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 138583.1
Deduct 528 from 590 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 10:
If we divide 620 by 528, we get 1 and a remainder of 92.
Put 1 as the next digit of the answer. 
Result so far: 138583.11
Subtracting 528 from 620 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

The quotient of the division is 138583.11, and the remainder is 0.092.
