We look at the division of 86037620 by 203 
The aim is to understand the frequency of 203 in 86037620.

Step 1:
When dividing 8 by 203, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 203

Let's proceed to step 2:
86 divided by 203 is 0 with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Fetch the next digit (0) from the dividend, attach it to 86 and continue: 860 / 203

Let's proceed to step 3:
The number 203 fits into 860 4 times, leaving a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 812 from 860 to get 48.
Include the next digit (3) from the dividend after 48, then repeat: 483 / 203

On to step 4:
If we divide 483 by 203, we get 2 and a remainder of 77.
Write down 2 as next digit of the result. 
Result so far: 42.0
If we subtract 406 from 483, we get 77.
Take the next digit (7) from the dividend and append it to 77, then repeat: 777 / 203

Step 5:
777 divided by 203 is 3 with a remainder of 168.
The next digit of our result is 3. 
Result so far: 423.0
If we subtract 609 from 777, we get 168.
Fetch the next digit (6) from the dividend, attach it to 168 and continue: 1686 / 203

On to step 6:
203 can be fit into 1686 8 times, resulting in a remainder of 62.
Put 8 as the next digit of the answer. 
Result so far: 4238.0
Deduct 1624 from 1686 and we're left with 62.
Include the next digit (2) from the dividend after 62, then repeat: 622 / 203

Moving on to step 7:
622 divided by 203 is 3 with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 42383.0
If we subtract 609 from 622, we get 13.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 203

On to step 8:
The number 203 fits into 130 0 times, leaving a remainder of 130.
Put 0 as the next digit of the answer. 
Result so far: 423830.0
If we take 0 away from 130, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 9:
If we divide 1300 by 203, we get 6 and a remainder of 82.
Put 6 as the next digit of the answer. 
Result so far: 423830.6
If we take 1218 away from 1300, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 10:
203 goes into 820 4 times with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 423830.64
If we take 812 away from 820, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
The number 203 fits into 80 0 times, leaving a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 423830.64
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 12:
203 goes into 800 3 times with a remainder of 191.
The number 3 becomes the next digit in our result. 
Result so far: 423830.6403
Subtract 609 from 800 to get 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Let's proceed to step 13:
203 goes into 1910 9 times with a remainder of 83.
The number 9 becomes the next digit in our result. 
Result so far: 423830.64039
Subtract 1827 from 1910 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Let's proceed to step 14:
203 can be fit into 830 4 times, resulting in a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 423830.640394
If we subtract 812 from 830, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 15:
The number 203 fits into 180 0 times, leaving a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 423830.640394
Deduct 0 from 180 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 16:
If we divide 1800 by 203, we get 8 and a remainder of 176.
Record the quotient 8 as the next digit in the result. 
Result so far: 423830.64039408
If we take 1624 away from 1800, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

The final result is 423830.64039408 with a remainder of 1.76e-07.
