43567251 ÷ 427 
The aim is to understand the frequency of 427 in 43567251.

Let's proceed to step 1:
427 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 427

Let's proceed to step 2:
If we divide 43 by 427, we get 0 and a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Grab the next digit (5) from the dividend, add it to 43, then carry on: 435 / 427

Moving on to step 3:
If we divide 435 by 427, we get 1 and a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 427 from 435 leaves us with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 427

On to step 4:
86 divided by 427 is 0 with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 86 leaves us with 86.
Include the next digit (7) from the dividend after 86, then repeat: 867 / 427

Moving on to step 5:
When dividing 867 by 427, we get 2 with a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 102.0
If we take 854 away from 867, we end up with 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 427

Step 6:
427 can be fit into 132 0 times, resulting in a remainder of 132.
Use 0 as the next digit of our solution. 
Result so far: 1020.0
Subtracting 0 from 132 leaves us with 132.
Include the next digit (5) from the dividend after 132, then repeat: 1325 / 427

Let's proceed to step 7:
When dividing 1325 by 427, we get 3 with a remainder of 44.
The number 3 becomes the next digit in our result. 
Result so far: 10203.0
If we subtract 1281 from 1325, we get 44.
Include the next digit (1) from the dividend after 44, then repeat: 441 / 427

Moving on to step 8:
441 divided by 427 is 1 with a remainder of 14.
The next digit of our result is 1. 
Result so far: 102031.0
If we take 427 away from 441, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
If we divide 140 by 427, we get 0 and a remainder of 140.
Put 0 as the next digit of the answer. 
Result so far: 102031.0
If we subtract 0 from 140, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 10:
When dividing 1400 by 427, we get 3 with a remainder of 119.
The next digit of our result is 3. 
Result so far: 102031.03
Subtract 1281 from 1400 to get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Moving on to step 11:
427 can be fit into 1190 2 times, resulting in a remainder of 336.
The next digit of our result is 2. 
Result so far: 102031.032
If we subtract 854 from 1190, we get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Going ahead to step 12:
When dividing 3360 by 427, we get 7 with a remainder of 371.
Use 7 as the next digit of our solution. 
Result so far: 102031.0327
Subtract 2989 from 3360 to get 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Step 13:
The number 427 fits into 3710 8 times, leaving a remainder of 294.
The next digit of our result is 8. 
Result so far: 102031.03278
Subtracting 3416 from 3710 leaves us with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Let's proceed to step 14:
If we divide 2940 by 427, we get 6 and a remainder of 378.
Record the quotient 6 as the next digit in the result. 
Result so far: 102031.032786
Subtract 2562 from 2940 to get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Moving on to step 15:
427 can be fit into 3780 8 times, resulting in a remainder of 364.
Write down 8 as next digit of the result. 
Result so far: 102031.0327868
Subtracting 3416 from 3780 leaves us with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Moving on to step 16:
3640 divided by 427 is 8 with a remainder of 224.
Write down 8 as next digit of the result. 
Result so far: 102031.03278688
Subtract 3416 from 3640 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

After the division, we end up with 102031.03278688 and a remainder of 2.24e-07.
