Let's divide 80358274 by 655
The aim is to understand the frequency of 655 in 80358274.

Step 1:
If we divide 8 by 655, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 655

On to step 2:
655 can be fit into 80 0 times, resulting in a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Fetch the next digit (3) from the dividend, attach it to 80 and continue: 803 / 655

Let's proceed to step 3:
655 goes into 803 1 times with a remainder of 148.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 148 after subtracting 655 from 803.
Grab the next digit (5) from the dividend, add it to 148, then carry on: 1485 / 655

Let's proceed to step 4:
1485 divided by 655 is 2 with a remainder of 175.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 175 after subtracting 1310 from 1485.
Include the next digit (8) from the dividend after 175, then repeat: 1758 / 655

Step 5:
If we divide 1758 by 655, we get 2 and a remainder of 448.
Use 2 as the next digit of our solution. 
Result so far: 122.0
If we subtract 1310 from 1758, we get 448.
Take the next digit (2) from the dividend and append it to 448, then repeat: 4482 / 655

Going ahead to step 6:
The number 655 fits into 4482 6 times, leaving a remainder of 552.
Put 6 as the next digit of the answer. 
Result so far: 1226.0
Deduct 3930 from 4482 and we're left with 552.
Include the next digit (7) from the dividend after 552, then repeat: 5527 / 655

Moving on to step 7:
655 can be fit into 5527 8 times, resulting in a remainder of 287.
The number 8 becomes the next digit in our result. 
Result so far: 12268.0
Subtracting 5240 from 5527 leaves us with 287.
Bring next digit (4) of the dividend behind the 287 and repeat the process: 2874 / 655

On to step 8:
2874 divided by 655 is 4 with a remainder of 254.
The number 4 becomes the next digit in our result. 
Result so far: 122684.0
Subtract 2620 from 2874 to get 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Step 9:
655 can be fit into 2540 3 times, resulting in a remainder of 575.
The number 3 becomes the next digit in our result. 
Result so far: 122684.3
The remainder is 575 after subtracting 1965 from 2540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Advancing to step 10:
The number 655 fits into 5750 8 times, leaving a remainder of 510.
The next digit of our result is 8. 
Result so far: 122684.38
If we subtract 5240 from 5750, we get 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Step 11:
655 goes into 5100 7 times with a remainder of 515.
Write down 7 as next digit of the result. 
Result so far: 122684.387
Subtract 4585 from 5100 to get 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Advancing to step 12:
When dividing 5150 by 655, we get 7 with a remainder of 565.
Use 7 as the next digit of our solution. 
Result so far: 122684.3877
If we take 4585 away from 5150, we end up with 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

The final outcome is 122684.3877, with a leftover of 0.00565.
