77765861 divided by 203 
The aim is to understand the frequency of 203 in 77765861.

Moving on to step 1:
When dividing 7 by 203, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 203

Moving on to step 2:
77 divided by 203 is 0 with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Fetch the next digit (7) from the dividend, attach it to 77 and continue: 777 / 203

On to step 3:
203 can be fit into 777 3 times, resulting in a remainder of 168.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 609 from 777 to get 168.
Grab the next digit (6) from the dividend, add it to 168, then carry on: 1686 / 203

On to step 4:
If we divide 1686 by 203, we get 8 and a remainder of 62.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
Deduct 1624 from 1686 and we're left with 62.
Take the next digit (5) from the dividend and append it to 62, then repeat: 625 / 203

Let's proceed to step 5:
If we divide 625 by 203, we get 3 and a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 383.0
If we subtract 609 from 625, we get 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 203

Moving on to step 6:
If we divide 168 by 203, we get 0 and a remainder of 168.
Write down 0 as next digit of the result. 
Result so far: 3830.0
Deduct 0 from 168 and we're left with 168.
Take the next digit (6) from the dividend and append it to 168, then repeat: 1686 / 203

Step 7:
1686 divided by 203 is 8 with a remainder of 62.
The number 8 becomes the next digit in our result. 
Result so far: 38308.0
Deduct 1624 from 1686 and we're left with 62.
Take the next digit (1) from the dividend and append it to 62, then repeat: 621 / 203

Going ahead to step 8:
621 divided by 203 is 3 with a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 383083.0
The remainder is 12 after subtracting 609 from 621.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
When dividing 120 by 203, we get 0 with a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 383083.0
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 10:
203 goes into 1200 5 times with a remainder of 185.
The number 5 becomes the next digit in our result. 
Result so far: 383083.05
The remainder is 185 after subtracting 1015 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Going ahead to step 11:
The number 203 fits into 1850 9 times, leaving a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 383083.059
Subtract 1827 from 1850 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 12:
When dividing 230 by 203, we get 1 with a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 383083.0591
If we subtract 203 from 230, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 13:
If we divide 270 by 203, we get 1 and a remainder of 67.
Write down 1 as next digit of the result. 
Result so far: 383083.05911
Subtract 203 from 270 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

After the division, we end up with 383083.05911 and a remainder of 6.7e-05.
