We're dividing 906025 by 73 
The aim is to understand the frequency of 73 in 906025.

On to step 1:
If we divide 9 by 73, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 73

Moving on to step 2:
73 can be fit into 90 1 times, resulting in a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 73 from 90 leaves us with 17.
Fetch the next digit (6) from the dividend, attach it to 17 and continue: 176 / 73

On to step 3:
73 can be fit into 176 2 times, resulting in a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Deduct 146 from 176 and we're left with 30.
Include the next digit (0) from the dividend after 30, then repeat: 300 / 73

Let's proceed to step 4:
73 can be fit into 300 4 times, resulting in a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 124.0
Subtract 292 from 300 to get 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 73

Step 5:
73 can be fit into 82 1 times, resulting in a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1241.0
Subtracting 73 from 82 leaves us with 9.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 73

Moving on to step 6:
The number 73 fits into 95 1 times, leaving a remainder of 22.
The next digit of our result is 1. 
Result so far: 12411.0
If we subtract 73 from 95, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 7:
When dividing 220 by 73, we get 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 12411.3
The remainder is 1 after subtracting 219 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 8:
73 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 12411.3
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
The number 73 fits into 100 1 times, leaving a remainder of 27.
The next digit of our result is 1. 
Result so far: 12411.301
Subtract 73 from 100 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 10:
The number 73 fits into 270 3 times, leaving a remainder of 51.
Write down 3 as next digit of the result. 
Result so far: 12411.3013
If we subtract 219 from 270, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 11:
When dividing 510 by 73, we get 6 with a remainder of 72.
The number 6 becomes the next digit in our result. 
Result so far: 12411.30136
The remainder is 72 after subtracting 438 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 12:
When dividing 720 by 73, we get 9 with a remainder of 63.
Use 9 as the next digit of our solution. 
Result so far: 12411.301369
Subtracting 657 from 720 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 13:
630 divided by 73 is 8 with a remainder of 46.
Record the quotient 8 as the next digit in the result. 
Result so far: 12411.3013698
If we subtract 584 from 630, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 14:
73 can be fit into 460 6 times, resulting in a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 12411.30136986
Subtracting 438 from 460 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

In conclusion, the division gives 12411.30136986 with a balance of 2.2e-08.
