87618645 ÷ 203 
The aim is to understand the frequency of 203 in 87618645.

Going ahead to step 1:
When dividing 8 by 203, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 203

On to step 2:
If we divide 87 by 203, we get 0 and a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Include the next digit (6) from the dividend after 87, then repeat: 876 / 203

Moving on to step 3:
The number 203 fits into 876 4 times, leaving a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 812 from 876 and we're left with 64.
Append the next digit (1) from the dividend to 64 and continue with: 641 / 203

Step 4:
203 can be fit into 641 3 times, resulting in a remainder of 32.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
The remainder is 32 after subtracting 609 from 641.
Grab the next digit (8) from the dividend, add it to 32, then carry on: 328 / 203

Going ahead to step 5:
The number 203 fits into 328 1 times, leaving a remainder of 125.
The number 1 becomes the next digit in our result. 
Result so far: 431.0
The remainder is 125 after subtracting 203 from 328.
Bring next digit (6) of the dividend behind the 125 and repeat the process: 1256 / 203

Moving on to step 6:
203 goes into 1256 6 times with a remainder of 38.
Write down 6 as next digit of the result. 
Result so far: 4316.0
If we take 1218 away from 1256, we end up with 38.
Bring next digit (4) of the dividend behind the 38 and repeat the process: 384 / 203

Advancing to step 7:
If we divide 384 by 203, we get 1 and a remainder of 181.
The number 1 becomes the next digit in our result. 
Result so far: 43161.0
Subtracting 203 from 384 leaves us with 181.
Take the next digit (5) from the dividend and append it to 181, then repeat: 1815 / 203

On to step 8:
1815 divided by 203 is 8 with a remainder of 191.
The next digit of our result is 8. 
Result so far: 431618.0
If we take 1624 away from 1815, we end up with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Step 9:
203 goes into 1910 9 times with a remainder of 83.
The next digit of our result is 9. 
Result so far: 431618.9
If we subtract 1827 from 1910, we 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.

Step 10:
203 can be fit into 830 4 times, resulting in a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 431618.94
Deduct 812 from 830 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 11:
The number 203 fits into 180 0 times, leaving a remainder of 180.
Put 0 as the next digit of the answer. 
Result so far: 431618.94
Subtracting 0 from 180 leaves us 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.

Step 12:
1800 divided by 203 is 8 with a remainder of 176.
The number 8 becomes the next digit in our result. 
Result so far: 431618.9408
The remainder is 176 after subtracting 1624 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Moving on to step 13:
When dividing 1760 by 203, we get 8 with a remainder of 136.
Write down 8 as next digit of the result. 
Result so far: 431618.94088
If we subtract 1624 from 1760, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Our division results in 431618.94088 with a remaining 0.000136.
