853047 ÷ 43 
The aim is to understand the frequency of 43 in 853047.

On to step 1:
The number 43 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 43

Step 2:
85 divided by 43 is 1 with a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 43 from 85 and we're left with 42.
Append the next digit (3) from the dividend to 42 and continue with: 423 / 43

Let's proceed to step 3:
The number 43 fits into 423 9 times, leaving a remainder of 36.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtracting 387 from 423 leaves us with 36.
Fetch the next digit (0) from the dividend, attach it to 36 and continue: 360 / 43

Moving on to step 4:
The number 43 fits into 360 8 times, leaving a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 198.0
Subtracting 344 from 360 leaves us with 16.
Append the next digit (4) from the dividend to 16 and continue with: 164 / 43

Advancing to step 5:
164 divided by 43 is 3 with a remainder of 35.
Write down 3 as next digit of the result. 
Result so far: 1983.0
Subtract 129 from 164 to get 35.
Fetch the next digit (7) from the dividend, attach it to 35 and continue: 357 / 43

Step 6:
When dividing 357 by 43, we get 8 with a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 19838.0
Deduct 344 from 357 and we're left with 13.
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 7:
The number 43 fits into 130 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 19838.3
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.

Step 8:
When dividing 10 by 43, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 19838.3
Deduct 0 from 10 and we're left 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.

On to step 9:
The number 43 fits into 100 2 times, leaving a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 19838.302
The remainder is 14 after subtracting 86 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 10:
When dividing 140 by 43, we get 3 with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 19838.3023
Subtracting 129 from 140 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 11:
43 can be fit into 110 2 times, resulting in a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 19838.30232
Subtracting 86 from 110 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
43 goes into 240 5 times with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 19838.302325
If we subtract 215 from 240, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 13:
When dividing 250 by 43, we get 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 19838.3023255
If we subtract 215 from 250, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 19838.3023255 with a remainder of 3.5e-07.
