Let's divide 391392 by 43
The aim is to understand the frequency of 43 in 391392.

Advancing to step 1:
43 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 43

Going ahead to step 2:
39 divided by 43 is 0 with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Include the next digit (1) from the dividend after 39, then repeat: 391 / 43

Moving on to step 3:
43 can be fit into 391 9 times, resulting in a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 387 from 391 and we're left with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 43

Advancing to step 4:
43 can be fit into 43 1 times, resulting in a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 91.0
The remainder is 0 after subtracting 43 from 43.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 43

Going ahead to step 5:
9 divided by 43 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 910.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 43

Let's proceed to step 6:
When dividing 92 by 43, we get 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 9102.0
Deduct 86 from 92 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
43 goes into 60 1 times with a remainder of 17.
The next digit of our result is 1. 
Result so far: 9102.1
Deduct 43 from 60 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 8:
The number 43 fits into 170 3 times, leaving a remainder of 41.
Record the quotient 3 as the next digit in the result. 
Result so far: 9102.13
Subtract 129 from 170 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 9:
When dividing 410 by 43, we get 9 with a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 9102.139
Subtracting 387 from 410 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 10:
When dividing 230 by 43, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 9102.1395
Subtract 215 from 230 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 11:
43 can be fit into 150 3 times, resulting in a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 9102.13953
If we take 129 away from 150, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 12:
210 divided by 43 is 4 with a remainder of 38.
The next digit of our result is 4. 
Result so far: 9102.139534
Deduct 172 from 210 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 13:
If we divide 380 by 43, we get 8 and a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 9102.1395348
If we subtract 344 from 380, we get 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 14:
43 goes into 360 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 9102.13953488
The remainder is 16 after subtracting 344 from 360.
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 9102.13953488 and a remainder of 1.6e-08.
