653484 divided by 43 
The aim is to understand the frequency of 43 in 653484.

On to step 1:
If we divide 6 by 43, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 43

Going ahead to step 2:
If we divide 65 by 43, we get 1 and a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 43 away from 65, we end up with 22.
Include the next digit (3) from the dividend after 22, then repeat: 223 / 43

On to step 3:
223 divided by 43 is 5 with a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtracting 215 from 223 leaves us with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 43

Moving on to step 4:
The number 43 fits into 84 1 times, leaving a remainder of 41.
The next digit of our result is 1. 
Result so far: 151.0
Subtract 43 from 84 to get 41.
Append the next digit (8) from the dividend to 41 and continue with: 418 / 43

Going ahead to step 5:
The number 43 fits into 418 9 times, leaving a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 1519.0
Deduct 387 from 418 and we're left with 31.
Fetch the next digit (4) from the dividend, attach it to 31 and continue: 314 / 43

Moving on to step 6:
If we divide 314 by 43, we get 7 and a remainder of 13.
The next digit of our result is 7. 
Result so far: 15197.0
If we take 301 away from 314, we end up 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.

Advancing to step 7:
130 divided by 43 is 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 15197.3
The remainder is 1 after subtracting 129 from 130.
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:
If we divide 10 by 43, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 15197.3
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.

Step 9:
100 divided by 43 is 2 with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 15197.302
Subtract 86 from 100 to 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.

Going ahead to step 10:
The number 43 fits into 140 3 times, leaving a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 15197.3023
If we take 129 away from 140, we end up 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.

Advancing to step 11:
43 can be fit into 110 2 times, resulting in a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 15197.30232
If we take 86 away from 110, we end up 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.
The next digit of our result is 5. 
Result so far: 15197.302325
The remainder is 25 after subtracting 215 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 13:
250 divided by 43 is 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 15197.3023255
Deduct 215 from 250 and we're left with 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 15197.3023255 with a remainder of 3.5e-07.
