Let's divide 305051 by 85
The aim is to understand the frequency of 85 in 305051.

On to step 1:
3 divided by 85 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 85

Let's proceed to step 2:
If we divide 30 by 85, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Bring next digit (5) of the dividend behind the 30 and repeat the process: 305 / 85

Let's proceed to step 3:
The number 85 fits into 305 3 times, leaving a remainder of 50.
The next digit of our result is 3. 
Result so far: 3.0
If we take 255 away from 305, we end up with 50.
Bring next digit (0) of the dividend behind the 50 and repeat the process: 500 / 85

On to step 4:
When dividing 500 by 85, we get 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
Subtract 425 from 500 to get 75.
Bring next digit (5) of the dividend behind the 75 and repeat the process: 755 / 85

Let's proceed to step 5:
85 goes into 755 8 times with a remainder of 75.
Put 8 as the next digit of the answer. 
Result so far: 358.0
Deduct 680 from 755 and we're left with 75.
Append the next digit (1) from the dividend to 75 and continue with: 751 / 85

On to step 6:
The number 85 fits into 751 8 times, leaving a remainder of 71.
The number 8 becomes the next digit in our result. 
Result so far: 3588.0
If we take 680 away from 751, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 7:
85 goes into 710 8 times with a remainder of 30.
The number 8 becomes the next digit in our result. 
Result so far: 3588.8
If we subtract 680 from 710, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
300 divided by 85 is 3 with a remainder of 45.
The number 3 becomes the next digit in our result. 
Result so far: 3588.83
The remainder is 45 after subtracting 255 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 9:
When dividing 450 by 85, we get 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 3588.835
The remainder is 25 after subtracting 425 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 10:
If we divide 250 by 85, we get 2 and a remainder of 80.
The number 2 becomes the next digit in our result. 
Result so far: 3588.8352
If we take 170 away from 250, we end up 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.

On to step 11:
85 goes into 800 9 times with a remainder of 35.
Record the quotient 9 as the next digit in the result. 
Result so far: 3588.83529
The remainder is 35 after subtracting 765 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 12:
85 can be fit into 350 4 times, resulting in a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 3588.835294
The remainder is 10 after subtracting 340 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
When dividing 100 by 85, we get 1 with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 3588.8352941
If we take 85 away from 100, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 14:
The number 85 fits into 150 1 times, leaving a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 3588.83529411
Deduct 85 from 150 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final result is 3588.83529411 with a remainder of 6.5e-08.
