Let's divide 903135 by 73
The aim is to understand the frequency of 73 in 903135.

Advancing to step 1:
When dividing 9 by 73, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 73

Let's proceed to step 2:
73 can be fit into 90 1 times, resulting in a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 73 from 90 to get 17.
Include the next digit (3) from the dividend after 17, then repeat: 173 / 73

Let's proceed to step 3:
173 divided by 73 is 2 with a remainder of 27.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtracting 146 from 173 leaves us with 27.
Append the next digit (1) from the dividend to 27 and continue with: 271 / 73

Advancing to step 4:
The number 73 fits into 271 3 times, leaving a remainder of 52.
Use 3 as the next digit of our solution. 
Result so far: 123.0
The remainder is 52 after subtracting 219 from 271.
Fetch the next digit (3) from the dividend, attach it to 52 and continue: 523 / 73

Advancing to step 5:
If we divide 523 by 73, we get 7 and a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 1237.0
Subtract 511 from 523 to get 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 73

On to step 6:
The number 73 fits into 125 1 times, leaving a remainder of 52.
The number 1 becomes the next digit in our result. 
Result so far: 12371.0
Subtracting 73 from 125 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 7:
520 divided by 73 is 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 12371.7
Subtract 511 from 520 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 8:
73 goes into 90 1 times with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 12371.71
If we take 73 away from 90, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 9:
170 divided by 73 is 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 12371.712
If we subtract 146 from 170, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 10:
73 can be fit into 240 3 times, resulting in a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 12371.7123
Subtracting 219 from 240 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 11:
73 goes into 210 2 times with a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 12371.71232
If we subtract 146 from 210, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 12:
73 can be fit into 640 8 times, resulting in a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 12371.712328
If we take 584 away from 640, 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.

Moving on to step 13:
73 goes into 560 7 times with a remainder of 49.
Put 7 as the next digit of the answer. 
Result so far: 12371.7123287
The remainder is 49 after subtracting 511 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 14:
73 can be fit into 490 6 times, resulting in a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 12371.71232876
The remainder is 52 after subtracting 438 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final outcome is 12371.71232876, with a leftover of 5.2e-08.
