We divide 42128175 by 655
The aim is to understand the frequency of 655 in 42128175.

Advancing to step 1:
4 divided by 655 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 655

Going ahead to step 2:
The number 655 fits into 42 0 times, leaving a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Include the next digit (1) from the dividend after 42, then repeat: 421 / 655

Step 3:
The number 655 fits into 421 0 times, leaving a remainder of 421.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 421 leaves us with 421.
Bring next digit (2) of the dividend behind the 421 and repeat the process: 4212 / 655

Going ahead to step 4:
The number 655 fits into 4212 6 times, leaving a remainder of 282.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 3930 from 4212 leaves us with 282.
Fetch the next digit (8) from the dividend, attach it to 282 and continue: 2828 / 655

Moving on to step 5:
The number 655 fits into 2828 4 times, leaving a remainder of 208.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
Subtract 2620 from 2828 to get 208.
Include the next digit (1) from the dividend after 208, then repeat: 2081 / 655

Moving on to step 6:
655 can be fit into 2081 3 times, resulting in a remainder of 116.
The number 3 becomes the next digit in our result. 
Result so far: 643.0
The remainder is 116 after subtracting 1965 from 2081.
Grab the next digit (7) from the dividend, add it to 116, then carry on: 1167 / 655

Advancing to step 7:
The number 655 fits into 1167 1 times, leaving a remainder of 512.
Put 1 as the next digit of the answer. 
Result so far: 6431.0
If we subtract 655 from 1167, we get 512.
Append the next digit (5) from the dividend to 512 and continue with: 5125 / 655

Step 8:
When dividing 5125 by 655, we get 7 with a remainder of 540.
Put 7 as the next digit of the answer. 
Result so far: 64317.0
If we take 4585 away from 5125, we end up with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Let's proceed to step 9:
If we divide 5400 by 655, we get 8 and a remainder of 160.
Use 8 as the next digit of our solution. 
Result so far: 64317.8
Subtract 5240 from 5400 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 10:
655 can be fit into 1600 2 times, resulting in a remainder of 290.
Put 2 as the next digit of the answer. 
Result so far: 64317.82
The remainder is 290 after subtracting 1310 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 11:
The number 655 fits into 2900 4 times, leaving a remainder of 280.
Write down 4 as next digit of the result. 
Result so far: 64317.824
Deduct 2620 from 2900 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 12:
When dividing 2800 by 655, we get 4 with a remainder of 180.
The next digit of our result is 4. 
Result so far: 64317.8244
If we subtract 2620 from 2800, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

The final outcome is 64317.8244, with a leftover of 0.0018.
