We're dividing 72146649 by 43 
The aim is to understand the frequency of 43 in 72146649.

Advancing to step 1:
The number 43 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 43

Going ahead to step 2:
If we divide 72 by 43, we get 1 and a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 43 from 72 leaves us with 29.
Fetch the next digit (1) from the dividend, attach it to 29 and continue: 291 / 43

Step 3:
43 goes into 291 6 times with a remainder of 33.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtracting 258 from 291 leaves us with 33.
Include the next digit (4) from the dividend after 33, then repeat: 334 / 43

Let's proceed to step 4:
If we divide 334 by 43, we get 7 and a remainder of 33.
Write down 7 as next digit of the result. 
Result so far: 167.0
Subtracting 301 from 334 leaves us with 33.
Grab the next digit (6) from the dividend, add it to 33, then carry on: 336 / 43

Let's proceed to step 5:
The number 43 fits into 336 7 times, leaving a remainder of 35.
The number 7 becomes the next digit in our result. 
Result so far: 1677.0
If we subtract 301 from 336, we get 35.
Take the next digit (6) from the dividend and append it to 35, then repeat: 356 / 43

Let's proceed to step 6:
356 divided by 43 is 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 16778.0
If we subtract 344 from 356, we get 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 43

On to step 7:
If we divide 124 by 43, we get 2 and a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 167782.0
If we subtract 86 from 124, we get 38.
Fetch the next digit (9) from the dividend, attach it to 38 and continue: 389 / 43

Advancing to step 8:
43 goes into 389 9 times with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 1677829.0
Subtracting 387 from 389 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
When dividing 20 by 43, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 1677829.0
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
43 goes into 200 4 times with a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 1677829.04
Subtract 172 from 200 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 11:
The number 43 fits into 280 6 times, leaving a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 1677829.046
Subtract 258 from 280 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 12:
43 can be fit into 220 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 1677829.0465
Subtract 215 from 220 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 13:
If we divide 50 by 43, we get 1 and a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 1677829.04651
The remainder is 7 after subtracting 43 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 14:
43 goes into 70 1 times with a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 1677829.046511
Subtracting 43 from 70 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Our division results in 1677829.046511 with a remaining 2.7e-06.
