We're dividing 2603189 by 522 
The aim is to understand the frequency of 522 in 2603189.

Moving on to step 1:
522 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 522

Moving on to step 2:
When dividing 26 by 522, we get 0 with a remainder of 26.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 26 leaves us with 26.
Append the next digit (0) from the dividend to 26 and continue with: 260 / 522

Going ahead to step 3:
When dividing 260 by 522, we get 0 with a remainder of 260.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 260 leaves us with 260.
Append the next digit (3) from the dividend to 260 and continue with: 2603 / 522

Step 4:
522 goes into 2603 4 times with a remainder of 515.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 2088 from 2603 to get 515.
Fetch the next digit (1) from the dividend, attach it to 515 and continue: 5151 / 522

Moving on to step 5:
522 can be fit into 5151 9 times, resulting in a remainder of 453.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
If we subtract 4698 from 5151, we get 453.
Append the next digit (8) from the dividend to 453 and continue with: 4538 / 522

Moving on to step 6:
4538 divided by 522 is 8 with a remainder of 362.
The next digit of our result is 8. 
Result so far: 498.0
Deduct 4176 from 4538 and we're left with 362.
Include the next digit (9) from the dividend after 362, then repeat: 3629 / 522

Advancing to step 7:
The number 522 fits into 3629 6 times, leaving a remainder of 497.
Use 6 as the next digit of our solution. 
Result so far: 4986.0
If we subtract 3132 from 3629, we get 497.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

Step 8:
522 goes into 4970 9 times with a remainder of 272.
Record the quotient 9 as the next digit in the result. 
Result so far: 4986.9
If we take 4698 away from 4970, we end up with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Moving on to step 9:
522 goes into 2720 5 times with a remainder of 110.
The next digit of our result is 5. 
Result so far: 4986.95
Subtract 2610 from 2720 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 10:
522 goes into 1100 2 times with a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 4986.952
Deduct 1044 from 1100 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 11:
When dividing 560 by 522, we get 1 with a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 4986.9521
If we subtract 522 from 560, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 12:
When dividing 380 by 522, we get 0 with a remainder of 380.
Put 0 as the next digit of the answer. 
Result so far: 4986.9521
Subtract 0 from 380 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 13:
The number 522 fits into 3800 7 times, leaving a remainder of 146.
Use 7 as the next digit of our solution. 
Result so far: 4986.952107
Deduct 3654 from 3800 and we're left with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Let's proceed to step 14:
The number 522 fits into 1460 2 times, leaving a remainder of 416.
Put 2 as the next digit of the answer. 
Result so far: 4986.9521072
The remainder is 416 after subtracting 1044 from 1460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Moving on to step 15:
If we divide 4160 by 522, we get 7 and a remainder of 506.
The next digit of our result is 7. 
Result so far: 4986.95210727
Deduct 3654 from 4160 and we're left with 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

The final outcome is 4986.95210727, with a leftover of 5.06e-07.
