We look at the division of 70232169 by 605 
The aim is to understand the frequency of 605 in 70232169.

Let's proceed to step 1:
7 divided by 605 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 605

Going ahead to step 2:
605 goes into 70 0 times with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 70 leaves us with 70.
Include the next digit (2) from the dividend after 70, then repeat: 702 / 605

Let's proceed to step 3:
702 divided by 605 is 1 with a remainder of 97.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 605 from 702 leaves us with 97.
Fetch the next digit (3) from the dividend, attach it to 97 and continue: 973 / 605

Moving on to step 4:
When dividing 973 by 605, we get 1 with a remainder of 368.
Put 1 as the next digit of the answer. 
Result so far: 11.0
The remainder is 368 after subtracting 605 from 973.
Fetch the next digit (2) from the dividend, attach it to 368 and continue: 3682 / 605

Advancing to step 5:
605 can be fit into 3682 6 times, resulting in a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 116.0
If we subtract 3630 from 3682, we get 52.
Append the next digit (1) from the dividend to 52 and continue with: 521 / 605

Step 6:
When dividing 521 by 605, we get 0 with a remainder of 521.
Write down 0 as next digit of the result. 
Result so far: 1160.0
The remainder is 521 after subtracting 0 from 521.
Grab the next digit (6) from the dividend, add it to 521, then carry on: 5216 / 605

Let's proceed to step 7:
605 goes into 5216 8 times with a remainder of 376.
Use 8 as the next digit of our solution. 
Result so far: 11608.0
If we take 4840 away from 5216, we end up with 376.
Grab the next digit (9) from the dividend, add it to 376, then carry on: 3769 / 605

On to step 8:
605 can be fit into 3769 6 times, resulting in a remainder of 139.
Put 6 as the next digit of the answer. 
Result so far: 116086.0
Subtracting 3630 from 3769 leaves us with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Going ahead to step 9:
1390 divided by 605 is 2 with a remainder of 180.
Record the quotient 2 as the next digit in the result. 
Result so far: 116086.2
Deduct 1210 from 1390 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 10:
If we divide 1800 by 605, we get 2 and a remainder of 590.
Use 2 as the next digit of our solution. 
Result so far: 116086.22
The remainder is 590 after subtracting 1210 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

After the division, we end up with 116086.22 and a remainder of 0.59.
