We're dividing 18777270 by 557 
The aim is to understand the frequency of 557 in 18777270.

Step 1:
557 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 557

Advancing to step 2:
18 divided by 557 is 0 with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Take the next digit (7) from the dividend and append it to 18, then repeat: 187 / 557

On to step 3:
The number 557 fits into 187 0 times, leaving a remainder of 187.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 187 leaves us with 187.
Bring next digit (7) of the dividend behind the 187 and repeat the process: 1877 / 557

Advancing to step 4:
1877 divided by 557 is 3 with a remainder of 206.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 206 after subtracting 1671 from 1877.
Grab the next digit (7) from the dividend, add it to 206, then carry on: 2067 / 557

Going ahead to step 5:
If we divide 2067 by 557, we get 3 and a remainder of 396.
Use 3 as the next digit of our solution. 
Result so far: 33.0
The remainder is 396 after subtracting 1671 from 2067.
Fetch the next digit (2) from the dividend, attach it to 396 and continue: 3962 / 557

Moving on to step 6:
3962 divided by 557 is 7 with a remainder of 63.
The next digit of our result is 7. 
Result so far: 337.0
The remainder is 63 after subtracting 3899 from 3962.
Take the next digit (7) from the dividend and append it to 63, then repeat: 637 / 557

Let's proceed to step 7:
If we divide 637 by 557, we get 1 and a remainder of 80.
Put 1 as the next digit of the answer. 
Result so far: 3371.0
If we take 557 away from 637, we end up with 80.
Append the next digit (0) from the dividend to 80 and continue with: 800 / 557

Advancing to step 8:
The number 557 fits into 800 1 times, leaving a remainder of 243.
Use 1 as the next digit of our solution. 
Result so far: 33711.0
If we take 557 away from 800, we end up with 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Going ahead to step 9:
When dividing 2430 by 557, we get 4 with a remainder of 202.
The next digit of our result is 4. 
Result so far: 33711.4
The remainder is 202 after subtracting 2228 from 2430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Advancing to step 10:
557 can be fit into 2020 3 times, resulting in a remainder of 349.
Put 3 as the next digit of the answer. 
Result so far: 33711.43
If we take 1671 away from 2020, we end up with 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Moving on to step 11:
When dividing 3490 by 557, we get 6 with a remainder of 148.
Use 6 as the next digit of our solution. 
Result so far: 33711.436
If we take 3342 away from 3490, we end up with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 12:
557 goes into 1480 2 times with a remainder of 366.
Put 2 as the next digit of the answer. 
Result so far: 33711.4362
Subtract 1114 from 1480 to get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Going ahead to step 13:
3660 divided by 557 is 6 with a remainder of 318.
The number 6 becomes the next digit in our result. 
Result so far: 33711.43626
If we subtract 3342 from 3660, we get 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

On to step 14:
If we divide 3180 by 557, we get 5 and a remainder of 395.
Write down 5 as next digit of the result. 
Result so far: 33711.436265
The remainder is 395 after subtracting 2785 from 3180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Going ahead to step 15:
557 goes into 3950 7 times with a remainder of 51.
Put 7 as the next digit of the answer. 
Result so far: 33711.4362657
If we take 3899 away from 3950, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 16:
If we divide 510 by 557, we get 0 and a remainder of 510.
Write down 0 as next digit of the result. 
Result so far: 33711.4362657
Subtract 0 from 510 to 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.

The final result is 33711.4362657 with a remainder of 5.1e-07.
