Let's divide 68606605 by 457
The aim is to understand the frequency of 457 in 68606605.

Advancing to step 1:
If we divide 6 by 457, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 457

On to step 2:
457 can be fit into 68 0 times, resulting in a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Take the next digit (6) from the dividend and append it to 68, then repeat: 686 / 457

Going ahead to step 3:
457 can be fit into 686 1 times, resulting in a remainder of 229.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 457 from 686 and we're left with 229.
Bring next digit (0) of the dividend behind the 229 and repeat the process: 2290 / 457

Going ahead to step 4:
If we divide 2290 by 457, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we subtract 2285 from 2290, we get 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 457

Going ahead to step 5:
457 can be fit into 56 0 times, resulting in a remainder of 56.
Write down 0 as next digit of the result. 
Result so far: 150.0
If we take 0 away from 56, we end up with 56.
Grab the next digit (6) from the dividend, add it to 56, then carry on: 566 / 457

Advancing to step 6:
If we divide 566 by 457, we get 1 and a remainder of 109.
The number 1 becomes the next digit in our result. 
Result so far: 1501.0
If we take 457 away from 566, we end up with 109.
Fetch the next digit (0) from the dividend, attach it to 109 and continue: 1090 / 457

Advancing to step 7:
457 goes into 1090 2 times with a remainder of 176.
Put 2 as the next digit of the answer. 
Result so far: 15012.0
The remainder is 176 after subtracting 914 from 1090.
Take the next digit (5) from the dividend and append it to 176, then repeat: 1765 / 457

Step 8:
457 goes into 1765 3 times with a remainder of 394.
Record the quotient 3 as the next digit in the result. 
Result so far: 150123.0
The remainder is 394 after subtracting 1371 from 1765.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Step 9:
The number 457 fits into 3940 8 times, leaving a remainder of 284.
The number 8 becomes the next digit in our result. 
Result so far: 150123.8
Deduct 3656 from 3940 and we're left with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Let's proceed to step 10:
The number 457 fits into 2840 6 times, leaving a remainder of 98.
Use 6 as the next digit of our solution. 
Result so far: 150123.86
Subtracting 2742 from 2840 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Advancing to step 11:
457 goes into 980 2 times with a remainder of 66.
Record the quotient 2 as the next digit in the result. 
Result so far: 150123.862
The remainder is 66 after subtracting 914 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 12:
The number 457 fits into 660 1 times, leaving a remainder of 203.
Use 1 as the next digit of our solution. 
Result so far: 150123.8621
Subtract 457 from 660 to get 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

On to step 13:
457 can be fit into 2030 4 times, resulting in a remainder of 202.
The next digit of our result is 4. 
Result so far: 150123.86214
Subtract 1828 from 2030 to get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Step 14:
457 goes into 2020 4 times with a remainder of 192.
Use 4 as the next digit of our solution. 
Result so far: 150123.862144
If we subtract 1828 from 2020, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

The final result is 150123.862144 with a remainder of 1.92e-05.
