We're dividing 751685 by 73 
The aim is to understand the frequency of 73 in 751685.

Step 1:
The number 73 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 73

On to step 2:
73 goes into 75 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 73 from 75 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 73

Moving on to step 3:
When dividing 21 by 73, we get 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 21 and we're left with 21.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 73

Step 4:
73 can be fit into 216 2 times, resulting in a remainder of 70.
Use 2 as the next digit of our solution. 
Result so far: 102.0
Deduct 146 from 216 and we're left with 70.
Grab the next digit (8) from the dividend, add it to 70, then carry on: 708 / 73

Moving on to step 5:
73 goes into 708 9 times with a remainder of 51.
Use 9 as the next digit of our solution. 
Result so far: 1029.0
If we take 657 away from 708, we end up with 51.
Bring next digit (5) of the dividend behind the 51 and repeat the process: 515 / 73

Going ahead to step 6:
73 goes into 515 7 times with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 10297.0
Subtracting 511 from 515 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
If we divide 40 by 73, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 10297.0
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 8:
If we divide 400 by 73, we get 5 and a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 10297.05
Deduct 365 from 400 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 9:
73 can be fit into 350 4 times, resulting in a remainder of 58.
Use 4 as the next digit of our solution. 
Result so far: 10297.054
Deduct 292 from 350 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 10:
73 goes into 580 7 times with a remainder of 69.
The next digit of our result is 7. 
Result so far: 10297.0547
If we take 511 away from 580, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 11:
690 divided by 73 is 9 with a remainder of 33.
Put 9 as the next digit of the answer. 
Result so far: 10297.05479
Subtracting 657 from 690 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 12:
If we divide 330 by 73, we get 4 and a remainder of 38.
Record the quotient 4 as the next digit in the result. 
Result so far: 10297.054794
If we subtract 292 from 330, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 13:
73 can be fit into 380 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 10297.0547945
If we subtract 365 from 380, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 14:
When dividing 150 by 73, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 10297.05479452
If we subtract 146 from 150, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 10297.05479452 with a remainder of 4e-09.
