We're dividing 41752099 by 603 
The aim is to understand the frequency of 603 in 41752099.

Step 1:
If we divide 4 by 603, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 603

Moving on to step 2:
When dividing 41 by 603, we get 0 with a remainder of 41.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 41 and we're left with 41.
Take the next digit (7) from the dividend and append it to 41, then repeat: 417 / 603

Step 3:
603 goes into 417 0 times with a remainder of 417.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 417 to get 417.
Take the next digit (5) from the dividend and append it to 417, then repeat: 4175 / 603

Going ahead to step 4:
The number 603 fits into 4175 6 times, leaving a remainder of 557.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 3618 from 4175 to get 557.
Fetch the next digit (2) from the dividend, attach it to 557 and continue: 5572 / 603

On to step 5:
When dividing 5572 by 603, we get 9 with a remainder of 145.
Write down 9 as next digit of the result. 
Result so far: 69.0
If we subtract 5427 from 5572, we get 145.
Include the next digit (0) from the dividend after 145, then repeat: 1450 / 603

Advancing to step 6:
1450 divided by 603 is 2 with a remainder of 244.
Put 2 as the next digit of the answer. 
Result so far: 692.0
Subtract 1206 from 1450 to get 244.
Bring next digit (9) of the dividend behind the 244 and repeat the process: 2449 / 603

Moving on to step 7:
If we divide 2449 by 603, we get 4 and a remainder of 37.
Put 4 as the next digit of the answer. 
Result so far: 6924.0
Subtract 2412 from 2449 to get 37.
Bring next digit (9) of the dividend behind the 37 and repeat the process: 379 / 603

Advancing to step 8:
603 goes into 379 0 times with a remainder of 379.
Record the quotient 0 as the next digit in the result. 
Result so far: 69240.0
If we take 0 away from 379, we end up with 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Advancing to step 9:
603 can be fit into 3790 6 times, resulting in a remainder of 172.
Write down 6 as next digit of the result. 
Result so far: 69240.6
If we subtract 3618 from 3790, we get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Let's proceed to step 10:
603 can be fit into 1720 2 times, resulting in a remainder of 514.
The number 2 becomes the next digit in our result. 
Result so far: 69240.62
Deduct 1206 from 1720 and we're left with 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Let's proceed to step 11:
The number 603 fits into 5140 8 times, leaving a remainder of 316.
Use 8 as the next digit of our solution. 
Result so far: 69240.628
Deduct 4824 from 5140 and we're left with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Going ahead to step 12:
603 goes into 3160 5 times with a remainder of 145.
Record the quotient 5 as the next digit in the result. 
Result so far: 69240.6285
If we subtract 3015 from 3160, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Advancing to step 13:
1450 divided by 603 is 2 with a remainder of 244.
Use 2 as the next digit of our solution. 
Result so far: 69240.62852
Subtract 1206 from 1450 to get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Advancing to step 14:
If we divide 2440 by 603, we get 4 and a remainder of 28.
The next digit of our result is 4. 
Result so far: 69240.628524
Subtract 2412 from 2440 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 15:
603 goes into 280 0 times with a remainder of 280.
The next digit of our result is 0. 
Result so far: 69240.628524
If we subtract 0 from 280, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 16:
If we divide 2800 by 603, we get 4 and a remainder of 388.
Write down 4 as next digit of the result. 
Result so far: 69240.62852404
The remainder is 388 after subtracting 2412 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

After the division, we end up with 69240.62852404 and a remainder of 3.88e-07.
