Let's divide 85038503 by 311
The aim is to understand the frequency of 311 in 85038503.

Advancing to step 1:
When dividing 8 by 311, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 311

Going ahead to step 2:
311 can be fit into 85 0 times, resulting in a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Take the next digit (0) from the dividend and append it to 85, then repeat: 850 / 311

Going ahead to step 3:
The number 311 fits into 850 2 times, leaving a remainder of 228.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 622 from 850 to get 228.
Grab the next digit (3) from the dividend, add it to 228, then carry on: 2283 / 311

Moving on to step 4:
311 goes into 2283 7 times with a remainder of 106.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
Deduct 2177 from 2283 and we're left with 106.
Fetch the next digit (8) from the dividend, attach it to 106 and continue: 1068 / 311

Step 5:
311 can be fit into 1068 3 times, resulting in a remainder of 135.
Record the quotient 3 as the next digit in the result. 
Result so far: 273.0
If we subtract 933 from 1068, we get 135.
Take the next digit (5) from the dividend and append it to 135, then repeat: 1355 / 311

Let's proceed to step 6:
311 can be fit into 1355 4 times, resulting in a remainder of 111.
The number 4 becomes the next digit in our result. 
Result so far: 2734.0
The remainder is 111 after subtracting 1244 from 1355.
Append the next digit (0) from the dividend to 111 and continue with: 1110 / 311

Advancing to step 7:
When dividing 1110 by 311, we get 3 with a remainder of 177.
Record the quotient 3 as the next digit in the result. 
Result so far: 27343.0
Subtract 933 from 1110 to get 177.
Take the next digit (3) from the dividend and append it to 177, then repeat: 1773 / 311

Advancing to step 8:
1773 divided by 311 is 5 with a remainder of 218.
Put 5 as the next digit of the answer. 
Result so far: 273435.0
Subtract 1555 from 1773 to get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Step 9:
311 can be fit into 2180 7 times, resulting in a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 273435.7
If we subtract 2177 from 2180, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 10:
If we divide 30 by 311, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 273435.7
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
If we divide 300 by 311, we get 0 and a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 273435.7
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

In conclusion, the division gives 273435.7 with a balance of 0.03.
