764406 ÷ 73 
The aim is to understand the frequency of 73 in 764406.

Let's proceed to step 1:
When dividing 7 by 73, 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 (6) from the dividend after 7, then repeat: 76 / 73

Let's proceed to step 2:
The number 73 fits into 76 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 3 after subtracting 73 from 76.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 73

Moving on to step 3:
73 can be fit into 34 0 times, resulting in a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 34 after subtracting 0 from 34.
Append the next digit (4) from the dividend to 34 and continue with: 344 / 73

Step 4:
73 can be fit into 344 4 times, resulting in a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 104.0
Subtract 292 from 344 to get 52.
Include the next digit (0) from the dividend after 52, then repeat: 520 / 73

On to step 5:
73 goes into 520 7 times with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 1047.0
Subtract 511 from 520 to get 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 73

Step 6:
When dividing 96 by 73, we get 1 with a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 10471.0
If we subtract 73 from 96, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 7:
The number 73 fits into 230 3 times, leaving a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 10471.3
Subtracting 219 from 230 leaves us 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.

Moving on to step 8:
If we divide 110 by 73, we get 1 and a remainder of 37.
The next digit of our result is 1. 
Result so far: 10471.31
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.

Let's proceed to step 9:
73 goes into 370 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 10471.315
If we take 365 away from 370, we end up 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.

Let's proceed to step 10:
50 divided by 73 is 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 10471.315
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.

Advancing to step 11:
500 divided by 73 is 6 with a remainder of 62.
Record the quotient 6 as the next digit in the result. 
Result so far: 10471.31506
Subtract 438 from 500 to 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.

On to step 12:
When dividing 620 by 73, we get 8 with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 10471.315068
If we subtract 584 from 620, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 13:
When dividing 360 by 73, we get 4 with a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 10471.3150684
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.

Going ahead to step 14:
When dividing 680 by 73, we get 9 with a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 10471.31506849
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.

The final outcome is 10471.31506849, with a leftover of 2.3e-08.
