We're dividing 90113302 by 602 
The aim is to understand the frequency of 602 in 90113302.

Let's proceed to step 1:
If we divide 9 by 602, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 602

Let's proceed to step 2:
The number 602 fits into 90 0 times, leaving a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Include the next digit (1) from the dividend after 90, then repeat: 901 / 602

Advancing to step 3:
The number 602 fits into 901 1 times, leaving a remainder of 299.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 602 from 901 to get 299.
Take the next digit (1) from the dividend and append it to 299, then repeat: 2991 / 602

Going ahead to step 4:
602 can be fit into 2991 4 times, resulting in a remainder of 583.
Put 4 as the next digit of the answer. 
Result so far: 14.0
The remainder is 583 after subtracting 2408 from 2991.
Bring next digit (3) of the dividend behind the 583 and repeat the process: 5833 / 602

Advancing to step 5:
If we divide 5833 by 602, we get 9 and a remainder of 415.
The number 9 becomes the next digit in our result. 
Result so far: 149.0
Deduct 5418 from 5833 and we're left with 415.
Include the next digit (3) from the dividend after 415, then repeat: 4153 / 602

Moving on to step 6:
When dividing 4153 by 602, we get 6 with a remainder of 541.
The next digit of our result is 6. 
Result so far: 1496.0
Subtracting 3612 from 4153 leaves us with 541.
Fetch the next digit (0) from the dividend, attach it to 541 and continue: 5410 / 602

Going ahead to step 7:
602 can be fit into 5410 8 times, resulting in a remainder of 594.
The next digit of our result is 8. 
Result so far: 14968.0
If we take 4816 away from 5410, we end up with 594.
Grab the next digit (2) from the dividend, add it to 594, then carry on: 5942 / 602

Step 8:
The number 602 fits into 5942 9 times, leaving a remainder of 524.
Put 9 as the next digit of the answer. 
Result so far: 149689.0
Subtract 5418 from 5942 to get 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Going ahead to step 9:
If we divide 5240 by 602, we get 8 and a remainder of 424.
Put 8 as the next digit of the answer. 
Result so far: 149689.8
Subtract 4816 from 5240 to get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Let's proceed to step 10:
When dividing 4240 by 602, we get 7 with a remainder of 26.
The next digit of our result is 7. 
Result so far: 149689.87
Deduct 4214 from 4240 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 11:
The number 602 fits into 260 0 times, leaving a remainder of 260.
Put 0 as the next digit of the answer. 
Result so far: 149689.87
Deduct 0 from 260 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 12:
602 can be fit into 2600 4 times, resulting in a remainder of 192.
Record the quotient 4 as the next digit in the result. 
Result so far: 149689.8704
Subtracting 2408 from 2600 leaves us with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Let's proceed to step 13:
If we divide 1920 by 602, we get 3 and a remainder of 114.
Record the quotient 3 as the next digit in the result. 
Result so far: 149689.87043
Deduct 1806 from 1920 and we're left with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Step 14:
602 goes into 1140 1 times with a remainder of 538.
The next digit of our result is 1. 
Result so far: 149689.870431
Deduct 602 from 1140 and we're left with 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Advancing to step 15:
602 goes into 5380 8 times with a remainder of 564.
Write down 8 as next digit of the result. 
Result so far: 149689.8704318
If we subtract 4816 from 5380, we get 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Going ahead to step 16:
602 goes into 5640 9 times with a remainder of 222.
Put 9 as the next digit of the answer. 
Result so far: 149689.87043189
If we take 5418 away from 5640, we end up with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

In conclusion, the division gives 149689.87043189 with a balance of 2.22e-07.
