915417 ÷ 73 
The aim is to understand the frequency of 73 in 915417.

Advancing to step 1:
When dividing 9 by 73, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 73

On to step 2:
When dividing 91 by 73, we get 1 with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 73 away from 91, we end up with 18.
Take the next digit (5) from the dividend and append it to 18, then repeat: 185 / 73

On to step 3:
73 can be fit into 185 2 times, resulting in a remainder of 39.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 146 from 185 to get 39.
Grab the next digit (4) from the dividend, add it to 39, then carry on: 394 / 73

Going ahead to step 4:
The number 73 fits into 394 5 times, leaving a remainder of 29.
Use 5 as the next digit of our solution. 
Result so far: 125.0
The remainder is 29 after subtracting 365 from 394.
Grab the next digit (1) from the dividend, add it to 29, then carry on: 291 / 73

Step 5:
When dividing 291 by 73, we get 3 with a remainder of 72.
The number 3 becomes the next digit in our result. 
Result so far: 1253.0
Subtract 219 from 291 to get 72.
Bring next digit (7) of the dividend behind the 72 and repeat the process: 727 / 73

Going ahead to step 6:
If we divide 727 by 73, we get 9 and a remainder of 70.
Record the quotient 9 as the next digit in the result. 
Result so far: 12539.0
If we subtract 657 from 727, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 7:
73 can be fit into 700 9 times, resulting in a remainder of 43.
Record the quotient 9 as the next digit in the result. 
Result so far: 12539.9
Subtract 657 from 700 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 8:
73 can be fit into 430 5 times, resulting in a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 12539.95
Subtract 365 from 430 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 9:
73 goes into 650 8 times with a remainder of 66.
Write down 8 as next digit of the result. 
Result so far: 12539.958
The remainder is 66 after subtracting 584 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 10:
73 can be fit into 660 9 times, resulting in a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 12539.9589
Subtract 657 from 660 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 11:
The number 73 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 12539.9589
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 12:
If we divide 300 by 73, we get 4 and a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 12539.958904
Subtracting 292 from 300 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 13:
When dividing 80 by 73, we get 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 12539.9589041
Subtract 73 from 80 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 14:
When dividing 70 by 73, we get 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 12539.9589041
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

In conclusion, the division gives 12539.9589041 with a balance of 7e-08.
