We're dividing 86529013 by 43 
The aim is to understand the frequency of 43 in 86529013.

Moving on to step 1:
When dividing 8 by 43, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 43

Moving on to step 2:
86 divided by 43 is 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 0 after subtracting 86 from 86.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 43

Advancing to step 3:
If we divide 5 by 43, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we subtract 0 from 5, we get 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 43

Step 4:
43 can be fit into 52 1 times, resulting in a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 201.0
Deduct 43 from 52 and we're left with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 43

Moving on to step 5:
99 divided by 43 is 2 with a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 2012.0
Subtract 86 from 99 to get 13.
Grab the next digit (0) from the dividend, add it to 13, then carry on: 130 / 43

On to step 6:
43 goes into 130 3 times with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 20123.0
Deduct 129 from 130 and we're left with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 43

Let's proceed to step 7:
43 goes into 11 0 times with a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 201230.0
Subtract 0 from 11 to get 11.
Fetch the next digit (3) from the dividend, attach it to 11 and continue: 113 / 43

Let's proceed to step 8:
43 goes into 113 2 times with a remainder of 27.
The next digit of our result is 2. 
Result so far: 2012302.0
Subtracting 86 from 113 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.

Moving on to step 9:
The number 43 fits into 270 6 times, leaving a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 2012302.6
Subtract 258 from 270 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
120 divided by 43 is 2 with a remainder of 34.
The next digit of our result is 2. 
Result so far: 2012302.62
If we take 86 away from 120, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 11:
The number 43 fits into 340 7 times, leaving a remainder of 39.
Write down 7 as next digit of the result. 
Result so far: 2012302.627
If we take 301 away from 340, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 12:
390 divided by 43 is 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 2012302.6279
If we take 387 away from 390, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 13:
43 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 2012302.6279
If we take 0 away from 30, we end up 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.

Advancing to step 14:
If we divide 300 by 43, we get 6 and a remainder of 42.
The number 6 becomes the next digit in our result. 
Result so far: 2012302.627906
If we take 258 away from 300, we end up 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 15:
The number 43 fits into 420 9 times, leaving a remainder of 33.
Put 9 as the next digit of the answer. 
Result so far: 2012302.6279069
Deduct 387 from 420 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 16:
The number 43 fits into 330 7 times, leaving a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 2012302.62790697
Deduct 301 from 330 and we're left 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.

The final outcome is 2012302.62790697, with a leftover of 2.9e-08.
