We look at the division of 311657 by 485 
The aim is to understand the frequency of 485 in 311657.

On to step 1:
485 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 485

Let's proceed to step 2:
485 goes into 31 0 times with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Grab the next digit (1) from the dividend, add it to 31, then carry on: 311 / 485

Going ahead to step 3:
If we divide 311 by 485, we get 0 and a remainder of 311.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 311 after subtracting 0 from 311.
Grab the next digit (6) from the dividend, add it to 311, then carry on: 3116 / 485

Advancing to step 4:
3116 divided by 485 is 6 with a remainder of 206.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 2910 away from 3116, we end up with 206.
Append the next digit (5) from the dividend to 206 and continue with: 2065 / 485

Going ahead to step 5:
485 goes into 2065 4 times with a remainder of 125.
Put 4 as the next digit of the answer. 
Result so far: 64.0
Subtracting 1940 from 2065 leaves us with 125.
Take the next digit (7) from the dividend and append it to 125, then repeat: 1257 / 485

On to step 6:
1257 divided by 485 is 2 with a remainder of 287.
Write down 2 as next digit of the result. 
Result so far: 642.0
Deduct 970 from 1257 and we're left with 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Advancing to step 7:
485 can be fit into 2870 5 times, resulting in a remainder of 445.
Record the quotient 5 as the next digit in the result. 
Result so far: 642.5
If we subtract 2425 from 2870, we get 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Advancing to step 8:
When dividing 4450 by 485, we get 9 with a remainder of 85.
Record the quotient 9 as the next digit in the result. 
Result so far: 642.59
If we take 4365 away from 4450, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 9:
485 goes into 850 1 times with a remainder of 365.
Put 1 as the next digit of the answer. 
Result so far: 642.591
The remainder is 365 after subtracting 485 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Step 10:
3650 divided by 485 is 7 with a remainder of 255.
The number 7 becomes the next digit in our result. 
Result so far: 642.5917
Subtracting 3395 from 3650 leaves us with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Moving on to step 11:
The number 485 fits into 2550 5 times, leaving a remainder of 125.
The number 5 becomes the next digit in our result. 
Result so far: 642.59175
The remainder is 125 after subtracting 2425 from 2550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 12:
1250 divided by 485 is 2 with a remainder of 280.
The next digit of our result is 2. 
Result so far: 642.591752
Subtract 970 from 1250 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 13:
2800 divided by 485 is 5 with a remainder of 375.
The number 5 becomes the next digit in our result. 
Result so far: 642.5917525
Subtract 2425 from 2800 to get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Going ahead to step 14:
485 can be fit into 3750 7 times, resulting in a remainder of 355.
Use 7 as the next digit of our solution. 
Result so far: 642.59175257
If we subtract 3395 from 3750, we get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

In conclusion, the division gives 642.59175257 with a balance of 3.55e-07.
