We look at the division of 86207267 by 603 
The aim is to understand the frequency of 603 in 86207267.

Step 1:
When dividing 8 by 603, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 603

Moving on to step 2:
86 divided by 603 is 0 with a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Append the next digit (2) from the dividend to 86 and continue with: 862 / 603

Let's proceed to step 3:
When dividing 862 by 603, we get 1 with a remainder of 259.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 259 after subtracting 603 from 862.
Fetch the next digit (0) from the dividend, attach it to 259 and continue: 2590 / 603

Step 4:
The number 603 fits into 2590 4 times, leaving a remainder of 178.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtracting 2412 from 2590 leaves us with 178.
Bring next digit (7) of the dividend behind the 178 and repeat the process: 1787 / 603

Let's proceed to step 5:
When dividing 1787 by 603, we get 2 with a remainder of 581.
The number 2 becomes the next digit in our result. 
Result so far: 142.0
The remainder is 581 after subtracting 1206 from 1787.
Append the next digit (2) from the dividend to 581 and continue with: 5812 / 603

Let's proceed to step 6:
The number 603 fits into 5812 9 times, leaving a remainder of 385.
The number 9 becomes the next digit in our result. 
Result so far: 1429.0
If we subtract 5427 from 5812, we get 385.
Take the next digit (6) from the dividend and append it to 385, then repeat: 3856 / 603

Step 7:
3856 divided by 603 is 6 with a remainder of 238.
Record the quotient 6 as the next digit in the result. 
Result so far: 14296.0
Subtract 3618 from 3856 to get 238.
Bring next digit (7) of the dividend behind the 238 and repeat the process: 2387 / 603

Step 8:
The number 603 fits into 2387 3 times, leaving a remainder of 578.
Write down 3 as next digit of the result. 
Result so far: 142963.0
Deduct 1809 from 2387 and we're left with 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Let's proceed to step 9:
603 goes into 5780 9 times with a remainder of 353.
The next digit of our result is 9. 
Result so far: 142963.9
Subtracting 5427 from 5780 leaves us with 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Moving on to step 10:
The number 603 fits into 3530 5 times, leaving a remainder of 515.
The number 5 becomes the next digit in our result. 
Result so far: 142963.95
If we subtract 3015 from 3530, we get 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

On to step 11:
603 goes into 5150 8 times with a remainder of 326.
Put 8 as the next digit of the answer. 
Result so far: 142963.958
Deduct 4824 from 5150 and we're left with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Let's proceed to step 12:
When dividing 3260 by 603, we get 5 with a remainder of 245.
Record the quotient 5 as the next digit in the result. 
Result so far: 142963.9585
Subtract 3015 from 3260 to get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Let's proceed to step 13:
603 goes into 2450 4 times with a remainder of 38.
Record the quotient 4 as the next digit in the result. 
Result so far: 142963.95854
Deduct 2412 from 2450 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 14:
The number 603 fits into 380 0 times, leaving a remainder of 380.
Write down 0 as next digit of the result. 
Result so far: 142963.95854
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.

Moving on to step 15:
3800 divided by 603 is 6 with a remainder of 182.
The next digit of our result is 6. 
Result so far: 142963.9585406
Deduct 3618 from 3800 and we're left with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Step 16:
603 can be fit into 1820 3 times, resulting in a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 142963.95854063
If we take 1809 away from 1820, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The quotient of the division is 142963.95854063, and the remainder is 1.1e-08.
