602903 ÷ 34 
The aim is to understand the frequency of 34 in 602903.

Let's proceed to step 1:
When dividing 6 by 34, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 34

Moving on to step 2:
The number 34 fits into 60 1 times, leaving a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 34 from 60 and we're left with 26.
Fetch the next digit (2) from the dividend, attach it to 26 and continue: 262 / 34

Going ahead to step 3:
When dividing 262 by 34, we get 7 with a remainder of 24.
The next digit of our result is 7. 
Result so far: 17.0
If we subtract 238 from 262, we get 24.
Take the next digit (9) from the dividend and append it to 24, then repeat: 249 / 34

Going ahead to step 4:
When dividing 249 by 34, we get 7 with a remainder of 11.
The next digit of our result is 7. 
Result so far: 177.0
Deduct 238 from 249 and we're left with 11.
Grab the next digit (0) from the dividend, add it to 11, then carry on: 110 / 34

Step 5:
The number 34 fits into 110 3 times, leaving a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 1773.0
Subtracting 102 from 110 leaves us with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 34

On to step 6:
34 goes into 83 2 times with a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 17732.0
If we subtract 68 from 83, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
When dividing 150 by 34, we get 4 with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 17732.4
The remainder is 14 after subtracting 136 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 8:
34 goes into 140 4 times with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 17732.44
If we take 136 away from 140, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 17732.44 and a remainder of 0.004.
