We look at the division of 1629817 by 602 
The aim is to understand the frequency of 602 in 1629817.

Let's proceed to step 1:
The number 602 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 602

On to step 2:
602 can be fit into 16 0 times, resulting in a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Take the next digit (2) from the dividend and append it to 16, then repeat: 162 / 602

Advancing to step 3:
602 can be fit into 162 0 times, resulting in a remainder of 162.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 162 to get 162.
Take the next digit (9) from the dividend and append it to 162, then repeat: 1629 / 602

Advancing to step 4:
The number 602 fits into 1629 2 times, leaving a remainder of 425.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 425 after subtracting 1204 from 1629.
Fetch the next digit (8) from the dividend, attach it to 425 and continue: 4258 / 602

Moving on to step 5:
4258 divided by 602 is 7 with a remainder of 44.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Deduct 4214 from 4258 and we're left with 44.
Take the next digit (1) from the dividend and append it to 44, then repeat: 441 / 602

Advancing to step 6:
602 goes into 441 0 times with a remainder of 441.
Write down 0 as next digit of the result. 
Result so far: 270.0
The remainder is 441 after subtracting 0 from 441.
Fetch the next digit (7) from the dividend, attach it to 441 and continue: 4417 / 602

On to step 7:
When dividing 4417 by 602, we get 7 with a remainder of 203.
The number 7 becomes the next digit in our result. 
Result so far: 2707.0
If we take 4214 away from 4417, we end up with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Going ahead to step 8:
If we divide 2030 by 602, we get 3 and a remainder of 224.
Record the quotient 3 as the next digit in the result. 
Result so far: 2707.3
The remainder is 224 after subtracting 1806 from 2030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Step 9:
If we divide 2240 by 602, we get 3 and a remainder of 434.
The number 3 becomes the next digit in our result. 
Result so far: 2707.33
Subtracting 1806 from 2240 leaves us with 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

The quotient of the division is 2707.33, and the remainder is 0.434.
