We're dividing 73712237 by 489 
The aim is to understand the frequency of 489 in 73712237.

Moving on to step 1:
When dividing 7 by 489, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 489

Let's proceed to step 2:
489 can be fit into 73 0 times, resulting in a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Fetch the next digit (7) from the dividend, attach it to 73 and continue: 737 / 489

Let's proceed to step 3:
489 can be fit into 737 1 times, resulting in a remainder of 248.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 248 after subtracting 489 from 737.
Bring next digit (1) of the dividend behind the 248 and repeat the process: 2481 / 489

Let's proceed to step 4:
489 goes into 2481 5 times with a remainder of 36.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 2445 away from 2481, we end up with 36.
Take the next digit (2) from the dividend and append it to 36, then repeat: 362 / 489

Going ahead to step 5:
If we divide 362 by 489, we get 0 and a remainder of 362.
The next digit of our result is 0. 
Result so far: 150.0
Subtract 0 from 362 to get 362.
Include the next digit (2) from the dividend after 362, then repeat: 3622 / 489

Going ahead to step 6:
The number 489 fits into 3622 7 times, leaving a remainder of 199.
Write down 7 as next digit of the result. 
Result so far: 1507.0
If we take 3423 away from 3622, we end up with 199.
Bring next digit (3) of the dividend behind the 199 and repeat the process: 1993 / 489

Advancing to step 7:
489 goes into 1993 4 times with a remainder of 37.
The number 4 becomes the next digit in our result. 
Result so far: 15074.0
If we subtract 1956 from 1993, we get 37.
Grab the next digit (7) from the dividend, add it to 37, then carry on: 377 / 489

Advancing to step 8:
If we divide 377 by 489, we get 0 and a remainder of 377.
Write down 0 as next digit of the result. 
Result so far: 150740.0
If we subtract 0 from 377, we get 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Advancing to step 9:
489 goes into 3770 7 times with a remainder of 347.
The next digit of our result is 7. 
Result so far: 150740.7
Deduct 3423 from 3770 and we're left with 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Advancing to step 10:
When dividing 3470 by 489, we get 7 with a remainder of 47.
Use 7 as the next digit of our solution. 
Result so far: 150740.77
If we take 3423 away from 3470, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

After the division, we end up with 150740.77 and a remainder of 0.047.
