90792663 divided by 602 
The aim is to understand the frequency of 602 in 90792663.

Going ahead to step 1:
When dividing 9 by 602, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 602

Going ahead to step 2:
If we divide 90 by 602, we get 0 and a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Fetch the next digit (7) from the dividend, attach it to 90 and continue: 907 / 602

Moving on to step 3:
The number 602 fits into 907 1 times, leaving a remainder of 305.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 602 from 907 and we're left with 305.
Take the next digit (9) from the dividend and append it to 305, then repeat: 3059 / 602

Step 4:
If we divide 3059 by 602, we get 5 and a remainder of 49.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we subtract 3010 from 3059, we get 49.
Bring next digit (2) of the dividend behind the 49 and repeat the process: 492 / 602

Advancing to step 5:
When dividing 492 by 602, we get 0 with a remainder of 492.
The number 0 becomes the next digit in our result. 
Result so far: 150.0
Subtract 0 from 492 to get 492.
Bring next digit (6) of the dividend behind the 492 and repeat the process: 4926 / 602

Advancing to step 6:
4926 divided by 602 is 8 with a remainder of 110.
Write down 8 as next digit of the result. 
Result so far: 1508.0
The remainder is 110 after subtracting 4816 from 4926.
Bring next digit (6) of the dividend behind the 110 and repeat the process: 1106 / 602

Advancing to step 7:
The number 602 fits into 1106 1 times, leaving a remainder of 504.
Put 1 as the next digit of the answer. 
Result so far: 15081.0
If we subtract 602 from 1106, we get 504.
Append the next digit (3) from the dividend to 504 and continue with: 5043 / 602

Going ahead to step 8:
The number 602 fits into 5043 8 times, leaving a remainder of 227.
The next digit of our result is 8. 
Result so far: 150818.0
Subtract 4816 from 5043 to get 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Step 9:
If we divide 2270 by 602, we get 3 and a remainder of 464.
The next digit of our result is 3. 
Result so far: 150818.3
The remainder is 464 after subtracting 1806 from 2270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Moving on to step 10:
4640 divided by 602 is 7 with a remainder of 426.
Use 7 as the next digit of our solution. 
Result so far: 150818.37
The remainder is 426 after subtracting 4214 from 4640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

On to step 11:
The number 602 fits into 4260 7 times, leaving a remainder of 46.
Write down 7 as next digit of the result. 
Result so far: 150818.377
Subtract 4214 from 4260 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final result is 150818.377 with a remainder of 0.0046.
