1880677 divided by 427 
The aim is to understand the frequency of 427 in 1880677.

Advancing to step 1:
When dividing 1 by 427, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 427

Moving on to step 2:
When dividing 18 by 427, we get 0 with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Append the next digit (8) from the dividend to 18 and continue with: 188 / 427

Advancing to step 3:
188 divided by 427 is 0 with a remainder of 188.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 188, we get 188.
Take the next digit (0) from the dividend and append it to 188, then repeat: 1880 / 427

Advancing to step 4:
1880 divided by 427 is 4 with a remainder of 172.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 1708 away from 1880, we end up with 172.
Append the next digit (6) from the dividend to 172 and continue with: 1726 / 427

Step 5:
427 goes into 1726 4 times with a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 44.0
If we subtract 1708 from 1726, we get 18.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 427

On to step 6:
187 divided by 427 is 0 with a remainder of 187.
Use 0 as the next digit of our solution. 
Result so far: 440.0
Deduct 0 from 187 and we're left with 187.
Include the next digit (7) from the dividend after 187, then repeat: 1877 / 427

Going ahead to step 7:
If we divide 1877 by 427, we get 4 and a remainder of 169.
The next digit of our result is 4. 
Result so far: 4404.0
If we subtract 1708 from 1877, we get 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Advancing to step 8:
427 goes into 1690 3 times with a remainder of 409.
The number 3 becomes the next digit in our result. 
Result so far: 4404.3
Subtract 1281 from 1690 to get 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Step 9:
When dividing 4090 by 427, we get 9 with a remainder of 247.
The next digit of our result is 9. 
Result so far: 4404.39
Subtracting 3843 from 4090 leaves us with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

On to step 10:
The number 427 fits into 2470 5 times, leaving a remainder of 335.
The number 5 becomes the next digit in our result. 
Result so far: 4404.395
Subtract 2135 from 2470 to get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Going ahead to step 11:
427 goes into 3350 7 times with a remainder of 361.
Put 7 as the next digit of the answer. 
Result so far: 4404.3957
The remainder is 361 after subtracting 2989 from 3350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Step 12:
3610 divided by 427 is 8 with a remainder of 194.
The next digit of our result is 8. 
Result so far: 4404.39578
Subtracting 3416 from 3610 leaves us with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Let's proceed to step 13:
If we divide 1940 by 427, we get 4 and a remainder of 232.
Use 4 as the next digit of our solution. 
Result so far: 4404.395784
Subtract 1708 from 1940 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 14:
427 can be fit into 2320 5 times, resulting in a remainder of 185.
The next digit of our result is 5. 
Result so far: 4404.3957845
Subtract 2135 from 2320 to get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Let's proceed to step 15:
427 goes into 1850 4 times with a remainder of 142.
The number 4 becomes the next digit in our result. 
Result so far: 4404.39578454
Subtracting 1708 from 1850 leaves us with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

The final outcome is 4404.39578454, with a leftover of 1.42e-07.
