Let's divide 3000811 by 355
The aim is to understand the frequency of 355 in 3000811.

On to step 1:
If we divide 3 by 355, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 355

Step 2:
30 divided by 355 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Include the next digit (0) from the dividend after 30, then repeat: 300 / 355

Going ahead to step 3:
When dividing 300 by 355, we get 0 with a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 300 and we're left with 300.
Grab the next digit (0) from the dividend, add it to 300, then carry on: 3000 / 355

Going ahead to step 4:
3000 divided by 355 is 8 with a remainder of 160.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 160 after subtracting 2840 from 3000.
Fetch the next digit (8) from the dividend, attach it to 160 and continue: 1608 / 355

Going ahead to step 5:
The number 355 fits into 1608 4 times, leaving a remainder of 188.
Write down 4 as next digit of the result. 
Result so far: 84.0
If we take 1420 away from 1608, we end up with 188.
Take the next digit (1) from the dividend and append it to 188, then repeat: 1881 / 355

Going ahead to step 6:
355 goes into 1881 5 times with a remainder of 106.
Write down 5 as next digit of the result. 
Result so far: 845.0
If we subtract 1775 from 1881, we get 106.
Fetch the next digit (1) from the dividend, attach it to 106 and continue: 1061 / 355

Advancing to step 7:
355 goes into 1061 2 times with a remainder of 351.
Put 2 as the next digit of the answer. 
Result so far: 8452.0
Deduct 710 from 1061 and we're left with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

On to step 8:
3510 divided by 355 is 9 with a remainder of 315.
Write down 9 as next digit of the result. 
Result so far: 8452.9
If we subtract 3195 from 3510, we get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Let's proceed to step 9:
355 can be fit into 3150 8 times, resulting in a remainder of 310.
Record the quotient 8 as the next digit in the result. 
Result so far: 8452.98
Subtracting 2840 from 3150 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 10:
355 goes into 3100 8 times with a remainder of 260.
Put 8 as the next digit of the answer. 
Result so far: 8452.988
Subtracting 2840 from 3100 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Our division results in 8452.988 with a remaining 0.026.
