We look at the division of 85533 by 73 
The aim is to understand the frequency of 73 in 85533.

On to step 1:
If we divide 8 by 73, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 73

Let's proceed to step 2:
When dividing 85 by 73, we get 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 73 from 85 and we're left with 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 73

Advancing to step 3:
73 can be fit into 125 1 times, resulting in a remainder of 52.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 52 after subtracting 73 from 125.
Bring next digit (3) of the dividend behind the 52 and repeat the process: 523 / 73

Moving on to step 4:
The number 73 fits into 523 7 times, leaving a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 117.0
Subtracting 511 from 523 leaves us with 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 73

On to step 5:
73 can be fit into 123 1 times, resulting in a remainder of 50.
Put 1 as the next digit of the answer. 
Result so far: 1171.0
If we take 73 away from 123, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 6:
The number 73 fits into 500 6 times, leaving a remainder of 62.
Write down 6 as next digit of the result. 
Result so far: 1171.6
If we subtract 438 from 500, we get 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 7:
If we divide 620 by 73, we get 8 and a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 1171.68
The remainder is 36 after subtracting 584 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 8:
73 goes into 360 4 times with a remainder of 68.
The next digit of our result is 4. 
Result so far: 1171.684
If we subtract 292 from 360, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 9:
The number 73 fits into 680 9 times, leaving a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 1171.6849
Subtracting 657 from 680 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 10:
If we divide 230 by 73, we get 3 and a remainder of 11.
The next digit of our result is 3. 
Result so far: 1171.68493
Deduct 219 from 230 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 11:
When dividing 110 by 73, we get 1 with a remainder of 37.
The next digit of our result is 1. 
Result so far: 1171.684931
The remainder is 37 after subtracting 73 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 12:
73 goes into 370 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 1171.6849315
Deduct 365 from 370 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 13:
The number 73 fits into 50 0 times, leaving a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 1171.6849315
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The quotient of the division is 1171.6849315, and the remainder is 5e-08.
