812888 divided by 43 
The aim is to understand the frequency of 43 in 812888.

Let's proceed to step 1:
43 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 43

Going ahead to step 2:
43 goes into 81 1 times with a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 43 from 81 leaves us with 38.
Fetch the next digit (2) from the dividend, attach it to 38 and continue: 382 / 43

On to step 3:
43 can be fit into 382 8 times, resulting in a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Deduct 344 from 382 and we're left with 38.
Include the next digit (8) from the dividend after 38, then repeat: 388 / 43

Let's proceed to step 4:
When dividing 388 by 43, we get 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 189.0
The remainder is 1 after subtracting 387 from 388.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 43

Advancing to step 5:
When dividing 18 by 43, we get 0 with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 1890.0
If we subtract 0 from 18, we get 18.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 43

Going ahead to step 6:
43 can be fit into 188 4 times, resulting in a remainder of 16.
The next digit of our result is 4. 
Result so far: 18904.0
If we subtract 172 from 188, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
If we divide 160 by 43, we get 3 and a remainder of 31.
Put 3 as the next digit of the answer. 
Result so far: 18904.3
The remainder is 31 after subtracting 129 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 8:
The number 43 fits into 310 7 times, leaving a remainder of 9.
The next digit of our result is 7. 
Result so far: 18904.37
If we subtract 301 from 310, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 9:
When dividing 90 by 43, we get 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 18904.372
If we subtract 86 from 90, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
If we divide 40 by 43, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 18904.372
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
400 divided by 43 is 9 with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 18904.37209
The remainder is 13 after subtracting 387 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 12:
If we divide 130 by 43, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 18904.372093
If we take 129 away from 130, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 13:
If we divide 10 by 43, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 18904.372093
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 14:
43 can be fit into 100 2 times, resulting in a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 18904.37209302
If we subtract 86 from 100, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 18904.37209302 and a remainder of 1.4e-08.
