80573794 divided by 602 
The aim is to understand the frequency of 602 in 80573794.

Let's proceed to step 1:
8 divided by 602 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 602

On to step 2:
When dividing 80 by 602, we get 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Fetch the next digit (5) from the dividend, attach it to 80 and continue: 805 / 602

Let's proceed to step 3:
805 divided by 602 is 1 with a remainder of 203.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 602 from 805 and we're left with 203.
Grab the next digit (7) from the dividend, add it to 203, then carry on: 2037 / 602

Let's proceed to step 4:
If we divide 2037 by 602, we get 3 and a remainder of 231.
The next digit of our result is 3. 
Result so far: 13.0
The remainder is 231 after subtracting 1806 from 2037.
Bring next digit (3) of the dividend behind the 231 and repeat the process: 2313 / 602

Step 5:
When dividing 2313 by 602, we get 3 with a remainder of 507.
Write down 3 as next digit of the result. 
Result so far: 133.0
Deduct 1806 from 2313 and we're left with 507.
Bring next digit (7) of the dividend behind the 507 and repeat the process: 5077 / 602

Moving on to step 6:
When dividing 5077 by 602, we get 8 with a remainder of 261.
Put 8 as the next digit of the answer. 
Result so far: 1338.0
Deduct 4816 from 5077 and we're left with 261.
Bring next digit (9) of the dividend behind the 261 and repeat the process: 2619 / 602

Let's proceed to step 7:
If we divide 2619 by 602, we get 4 and a remainder of 211.
The next digit of our result is 4. 
Result so far: 13384.0
If we subtract 2408 from 2619, we get 211.
Include the next digit (4) from the dividend after 211, then repeat: 2114 / 602

On to step 8:
When dividing 2114 by 602, we get 3 with a remainder of 308.
Record the quotient 3 as the next digit in the result. 
Result so far: 133843.0
Subtract 1806 from 2114 to get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

On to step 9:
The number 602 fits into 3080 5 times, leaving a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 133843.5
The remainder is 70 after subtracting 3010 from 3080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 10:
If we divide 700 by 602, we get 1 and a remainder of 98.
The next digit of our result is 1. 
Result so far: 133843.51
If we take 602 away from 700, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 11:
602 goes into 980 1 times with a remainder of 378.
Record the quotient 1 as the next digit in the result. 
Result so far: 133843.511
Subtract 602 from 980 to get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

The final outcome is 133843.511, with a leftover of 0.0378.
