We divide 917680 by 73
The aim is to understand the frequency of 73 in 917680.

Moving on to step 1:
When dividing 9 by 73, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 73

Moving on to step 2:
73 can be fit into 91 1 times, resulting in a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 73 from 91, we get 18.
Take the next digit (7) from the dividend and append it to 18, then repeat: 187 / 73

Going ahead to step 3:
If we divide 187 by 73, we get 2 and a remainder of 41.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 146 from 187 leaves us with 41.
Grab the next digit (6) from the dividend, add it to 41, then carry on: 416 / 73

Advancing to step 4:
73 goes into 416 5 times with a remainder of 51.
Record the quotient 5 as the next digit in the result. 
Result so far: 125.0
The remainder is 51 after subtracting 365 from 416.
Take the next digit (8) from the dividend and append it to 51, then repeat: 518 / 73

Moving on to step 5:
73 goes into 518 7 times with a remainder of 7.
The next digit of our result is 7. 
Result so far: 1257.0
Subtract 511 from 518 to get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 73

Going ahead to step 6:
If we divide 70 by 73, we get 0 and a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 12570.0
Subtracting 0 from 70 leaves us 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.

Advancing to step 7:
73 goes into 700 9 times with a remainder of 43.
Write down 9 as next digit of the result. 
Result so far: 12570.9
Subtracting 657 from 700 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 8:
If we divide 430 by 73, we get 5 and a remainder of 65.
The next digit of our result is 5. 
Result so far: 12570.95
The remainder is 65 after subtracting 365 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 9:
The number 73 fits into 650 8 times, leaving a remainder of 66.
The number 8 becomes the next digit in our result. 
Result so far: 12570.958
Subtract 584 from 650 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 10:
The number 73 fits into 660 9 times, leaving a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 12570.9589
Subtracting 657 from 660 leaves us with 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:
If we divide 30 by 73, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 12570.9589
Subtracting 0 from 30 leaves us with 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:
73 goes into 300 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 12570.958904
Deduct 292 from 300 and we're left 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.

Advancing to step 13:
80 divided by 73 is 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 12570.9589041
If we take 73 away from 80, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 14:
If we divide 70 by 73, we get 0 and a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 12570.9589041
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 12570.9589041 and a remainder of 7e-08.
