We're dividing 525236 by 43 
The aim is to understand the frequency of 43 in 525236.

Step 1:
The number 43 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 43

Going ahead to step 2:
If we divide 52 by 43, we get 1 and a remainder of 9.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 9 after subtracting 43 from 52.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 43

On to step 3:
95 divided by 43 is 2 with a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we take 86 away from 95, we end up with 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 43

Advancing to step 4:
43 goes into 92 2 times with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 122.0
Deduct 86 from 92 and we're left with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 43

Going ahead to step 5:
The number 43 fits into 63 1 times, leaving a remainder of 20.
The next digit of our result is 1. 
Result so far: 1221.0
If we subtract 43 from 63, we get 20.
Fetch the next digit (6) from the dividend, attach it to 20 and continue: 206 / 43

Step 6:
When dividing 206 by 43, we get 4 with a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 12214.0
The remainder is 34 after subtracting 172 from 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 7:
43 can be fit into 340 7 times, resulting in a remainder of 39.
The next digit of our result is 7. 
Result so far: 12214.7
Subtract 301 from 340 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 8:
If we divide 390 by 43, we get 9 and a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 12214.79
The remainder is 3 after subtracting 387 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 9:
30 divided by 43 is 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 12214.79
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
When dividing 300 by 43, we get 6 with a remainder of 42.
The next digit of our result is 6. 
Result so far: 12214.7906
Subtracting 258 from 300 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 11:
43 goes into 420 9 times with a remainder of 33.
Write down 9 as next digit of the result. 
Result so far: 12214.79069
If we subtract 387 from 420, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 12:
The number 43 fits into 330 7 times, leaving a remainder of 29.
Record the quotient 7 as the next digit in the result. 
Result so far: 12214.790697
Subtracting 301 from 330 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 13:
The number 43 fits into 290 6 times, leaving a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 12214.7906976
Subtracting 258 from 290 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 14:
43 goes into 320 7 times with a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 12214.79069767
Deduct 301 from 320 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

After the division, we end up with 12214.79069767 and a remainder of 1.9e-08.
