We look at the division of 619238 by 485 
The aim is to understand the frequency of 485 in 619238.

Step 1:
485 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 485

On to step 2:
When dividing 61 by 485, we get 0 with a remainder of 61.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 61 to get 61.
Bring next digit (9) of the dividend behind the 61 and repeat the process: 619 / 485

Step 3:
485 can be fit into 619 1 times, resulting in a remainder of 134.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 134 after subtracting 485 from 619.
Bring next digit (2) of the dividend behind the 134 and repeat the process: 1342 / 485

Going ahead to step 4:
When dividing 1342 by 485, we get 2 with a remainder of 372.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 970 from 1342, we get 372.
Grab the next digit (3) from the dividend, add it to 372, then carry on: 3723 / 485

Going ahead to step 5:
485 goes into 3723 7 times with a remainder of 328.
Write down 7 as next digit of the result. 
Result so far: 127.0
Subtracting 3395 from 3723 leaves us with 328.
Fetch the next digit (8) from the dividend, attach it to 328 and continue: 3288 / 485

On to step 6:
485 can be fit into 3288 6 times, resulting in a remainder of 378.
The number 6 becomes the next digit in our result. 
Result so far: 1276.0
Deduct 2910 from 3288 and we're left with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Moving on to step 7:
When dividing 3780 by 485, we get 7 with a remainder of 385.
Use 7 as the next digit of our solution. 
Result so far: 1276.7
If we take 3395 away from 3780, we end up with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

On to step 8:
When dividing 3850 by 485, we get 7 with a remainder of 455.
Record the quotient 7 as the next digit in the result. 
Result so far: 1276.77
Deduct 3395 from 3850 and we're left with 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

The final outcome is 1276.77, with a leftover of 0.455.
