77954738 divided by 427 
The aim is to understand the frequency of 427 in 77954738.

Step 1:
427 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 427

Step 2:
The number 427 fits into 77 0 times, leaving a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Append the next digit (9) from the dividend to 77 and continue with: 779 / 427

Advancing to step 3:
427 goes into 779 1 times with a remainder of 352.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 427 from 779 to get 352.
Grab the next digit (5) from the dividend, add it to 352, then carry on: 3525 / 427

On to step 4:
If we divide 3525 by 427, we get 8 and a remainder of 109.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we subtract 3416 from 3525, we get 109.
Take the next digit (4) from the dividend and append it to 109, then repeat: 1094 / 427

On to step 5:
When dividing 1094 by 427, we get 2 with a remainder of 240.
Put 2 as the next digit of the answer. 
Result so far: 182.0
Subtract 854 from 1094 to get 240.
Include the next digit (7) from the dividend after 240, then repeat: 2407 / 427

Moving on to step 6:
2407 divided by 427 is 5 with a remainder of 272.
Use 5 as the next digit of our solution. 
Result so far: 1825.0
Subtract 2135 from 2407 to get 272.
Grab the next digit (3) from the dividend, add it to 272, then carry on: 2723 / 427

Going ahead to step 7:
427 goes into 2723 6 times with a remainder of 161.
The number 6 becomes the next digit in our result. 
Result so far: 18256.0
Deduct 2562 from 2723 and we're left with 161.
Append the next digit (8) from the dividend to 161 and continue with: 1618 / 427

Let's proceed to step 8:
427 can be fit into 1618 3 times, resulting in a remainder of 337.
Write down 3 as next digit of the result. 
Result so far: 182563.0
Subtract 1281 from 1618 to get 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Going ahead to step 9:
The number 427 fits into 3370 7 times, leaving a remainder of 381.
The next digit of our result is 7. 
Result so far: 182563.7
Subtracting 2989 from 3370 leaves us with 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Moving on to step 10:
If we divide 3810 by 427, we get 8 and a remainder of 394.
The next digit of our result is 8. 
Result so far: 182563.78
Subtracting 3416 from 3810 leaves us with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Advancing to step 11:
3940 divided by 427 is 9 with a remainder of 97.
Put 9 as the next digit of the answer. 
Result so far: 182563.789
Subtract 3843 from 3940 to get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 12:
When dividing 970 by 427, we get 2 with a remainder of 116.
The number 2 becomes the next digit in our result. 
Result so far: 182563.7892
If we subtract 854 from 970, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Advancing to step 13:
427 can be fit into 1160 2 times, resulting in a remainder of 306.
The number 2 becomes the next digit in our result. 
Result so far: 182563.78922
If we take 854 away from 1160, we end up with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

The final result is 182563.78922 with a remainder of 0.000306.
