Let's divide 9159263 by 602
The aim is to understand the frequency of 602 in 9159263.

On to step 1:
9 divided by 602 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 602

Let's proceed to step 2:
91 divided by 602 is 0 with a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Take the next digit (5) from the dividend and append it to 91, then repeat: 915 / 602

Step 3:
When dividing 915 by 602, we get 1 with a remainder of 313.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 602 from 915 to get 313.
Fetch the next digit (9) from the dividend, attach it to 313 and continue: 3139 / 602

Step 4:
The number 602 fits into 3139 5 times, leaving a remainder of 129.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 3010 from 3139 and we're left with 129.
Fetch the next digit (2) from the dividend, attach it to 129 and continue: 1292 / 602

Going ahead to step 5:
602 goes into 1292 2 times with a remainder of 88.
The next digit of our result is 2. 
Result so far: 152.0
The remainder is 88 after subtracting 1204 from 1292.
Fetch the next digit (6) from the dividend, attach it to 88 and continue: 886 / 602

Step 6:
If we divide 886 by 602, we get 1 and a remainder of 284.
Record the quotient 1 as the next digit in the result. 
Result so far: 1521.0
Subtracting 602 from 886 leaves us with 284.
Grab the next digit (3) from the dividend, add it to 284, then carry on: 2843 / 602

Let's proceed to step 7:
602 goes into 2843 4 times with a remainder of 435.
Put 4 as the next digit of the answer. 
Result so far: 15214.0
Subtract 2408 from 2843 to get 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Step 8:
4350 divided by 602 is 7 with a remainder of 136.
Record the quotient 7 as the next digit in the result. 
Result so far: 15214.7
If we take 4214 away from 4350, 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.

On to step 9:
The number 602 fits into 1360 2 times, leaving a remainder of 156.
Use 2 as the next digit of our solution. 
Result so far: 15214.72
The remainder is 156 after subtracting 1204 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Advancing to step 10:
The number 602 fits into 1560 2 times, leaving a remainder of 356.
Write down 2 as next digit of the result. 
Result so far: 15214.722
If we subtract 1204 from 1560, we get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

The final outcome is 15214.722, with a leftover of 0.0356.
