We look at the division of 79220324 by 602 
The aim is to understand the frequency of 602 in 79220324.

Going ahead to step 1:
7 divided by 602 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 602

Let's proceed to step 2:
602 can be fit into 79 0 times, resulting in a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 79, we get 79.
Grab the next digit (2) from the dividend, add it to 79, then carry on: 792 / 602

Let's proceed to step 3:
If we divide 792 by 602, we get 1 and a remainder of 190.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 602 from 792 to get 190.
Grab the next digit (2) from the dividend, add it to 190, then carry on: 1902 / 602

Advancing to step 4:
When dividing 1902 by 602, we get 3 with a remainder of 96.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 1806 from 1902 and we're left with 96.
Grab the next digit (0) from the dividend, add it to 96, then carry on: 960 / 602

Let's proceed to step 5:
960 divided by 602 is 1 with a remainder of 358.
Put 1 as the next digit of the answer. 
Result so far: 131.0
If we subtract 602 from 960, we get 358.
Take the next digit (3) from the dividend and append it to 358, then repeat: 3583 / 602

Advancing to step 6:
602 goes into 3583 5 times with a remainder of 573.
The next digit of our result is 5. 
Result so far: 1315.0
The remainder is 573 after subtracting 3010 from 3583.
Take the next digit (2) from the dividend and append it to 573, then repeat: 5732 / 602

Moving on to step 7:
5732 divided by 602 is 9 with a remainder of 314.
The number 9 becomes the next digit in our result. 
Result so far: 13159.0
The remainder is 314 after subtracting 5418 from 5732.
Append the next digit (4) from the dividend to 314 and continue with: 3144 / 602

Let's proceed to step 8:
If we divide 3144 by 602, we get 5 and a remainder of 134.
Use 5 as the next digit of our solution. 
Result so far: 131595.0
The remainder is 134 after subtracting 3010 from 3144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

On to step 9:
602 can be fit into 1340 2 times, resulting in a remainder of 136.
Put 2 as the next digit of the answer. 
Result so far: 131595.2
If we take 1204 away from 1340, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 10:
602 can be fit into 1360 2 times, resulting in a remainder of 156.
Write down 2 as next digit of the result. 
Result so far: 131595.22
If we subtract 1204 from 1360, we get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

The final outcome is 131595.22, with a leftover of 0.156.
