426300 ÷ 43 
The aim is to understand the frequency of 43 in 426300.

On to step 1:
If we divide 4 by 43, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 43

Let's proceed to step 2:
43 can be fit into 42 0 times, resulting in a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Take the next digit (6) from the dividend and append it to 42, then repeat: 426 / 43

Advancing to step 3:
If we divide 426 by 43, we get 9 and a remainder of 39.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 387 from 426 leaves us with 39.
Fetch the next digit (3) from the dividend, attach it to 39 and continue: 393 / 43

Step 4:
43 goes into 393 9 times with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 99.0
If we take 387 away from 393, we end up with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 43

Advancing to step 5:
If we divide 60 by 43, we get 1 and a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 991.0
If we take 43 away from 60, we end up with 17.
Bring next digit (0) of the dividend behind the 17 and repeat the process: 170 / 43

Advancing to step 6:
The number 43 fits into 170 3 times, leaving a remainder of 41.
The number 3 becomes the next digit in our result. 
Result so far: 9913.0
Deduct 129 from 170 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 7:
410 divided by 43 is 9 with a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 9913.9
Subtract 387 from 410 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 8:
When dividing 230 by 43, we get 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 9913.95
Deduct 215 from 230 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 9:
If we divide 150 by 43, we get 3 and a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 9913.953
If we subtract 129 from 150, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 10:
43 goes into 210 4 times with a remainder of 38.
Record the quotient 4 as the next digit in the result. 
Result so far: 9913.9534
If we subtract 172 from 210, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 11:
380 divided by 43 is 8 with a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 9913.95348
If we take 344 away from 380, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 12:
43 can be fit into 360 8 times, resulting in a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 9913.953488
Subtracting 344 from 360 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 9913.953488 and a remainder of 1.6e-06.
