We're dividing 58449899 by 902 
The aim is to understand the frequency of 902 in 58449899.

Going ahead to step 1:
The number 902 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 902

Moving on to step 2:
The number 902 fits into 58 0 times, leaving a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 58 leaves us with 58.
Include the next digit (4) from the dividend after 58, then repeat: 584 / 902

Step 3:
If we divide 584 by 902, we get 0 and a remainder of 584.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 584 after subtracting 0 from 584.
Append the next digit (4) from the dividend to 584 and continue with: 5844 / 902

Let's proceed to step 4:
902 can be fit into 5844 6 times, resulting in a remainder of 432.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 5412 away from 5844, we end up with 432.
Include the next digit (9) from the dividend after 432, then repeat: 4329 / 902

Step 5:
902 goes into 4329 4 times with a remainder of 721.
The next digit of our result is 4. 
Result so far: 64.0
Subtract 3608 from 4329 to get 721.
Take the next digit (8) from the dividend and append it to 721, then repeat: 7218 / 902

Step 6:
7218 divided by 902 is 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 648.0
Subtracting 7216 from 7218 leaves us with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 902

Let's proceed to step 7:
902 goes into 29 0 times with a remainder of 29.
The next digit of our result is 0. 
Result so far: 6480.0
If we take 0 away from 29, we end up with 29.
Grab the next digit (9) from the dividend, add it to 29, then carry on: 299 / 902

Going ahead to step 8:
299 divided by 902 is 0 with a remainder of 299.
Record the quotient 0 as the next digit in the result. 
Result so far: 64800.0
Deduct 0 from 299 and we're left with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Going ahead to step 9:
The number 902 fits into 2990 3 times, leaving a remainder of 284.
Record the quotient 3 as the next digit in the result. 
Result so far: 64800.3
The remainder is 284 after subtracting 2706 from 2990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Advancing to step 10:
2840 divided by 902 is 3 with a remainder of 134.
Put 3 as the next digit of the answer. 
Result so far: 64800.33
Subtracting 2706 from 2840 leaves us with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

The final outcome is 64800.33, with a leftover of 0.134.
