15529 divided by 43 
The aim is to understand the frequency of 43 in 15529.

On to step 1:
43 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 43

Moving on to step 2:
If we divide 15 by 43, we get 0 and a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 43

Step 3:
If we divide 155 by 43, we get 3 and a remainder of 26.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 26 after subtracting 129 from 155.
Include the next digit (2) from the dividend after 26, then repeat: 262 / 43

Step 4:
If we divide 262 by 43, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 36.0
If we take 258 away from 262, we end up with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 43

On to step 5:
The number 43 fits into 49 1 times, leaving a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 361.0
If we take 43 away from 49, we end up 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.

On to step 6:
If we divide 60 by 43, we get 1 and a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 361.1
Subtracting 43 from 60 leaves us 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.

Step 7:
43 goes into 170 3 times with a remainder of 41.
The number 3 becomes the next digit in our result. 
Result so far: 361.13
Deduct 129 from 170 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 8:
When dividing 410 by 43, we get 9 with a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 361.139
Deduct 387 from 410 and we're left 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.

Going ahead to step 9:
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: 361.1395
If we subtract 215 from 230, we 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.

Step 10:
43 can be fit into 150 3 times, resulting in a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 361.13953
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.

Step 11:
If we divide 210 by 43, we get 4 and a remainder of 38.
Record the quotient 4 as the next digit in the result. 
Result so far: 361.139534
If we subtract 172 from 210, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 12:
When dividing 380 by 43, we get 8 with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 361.1395348
Subtracting 344 from 380 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 13:
When dividing 360 by 43, we get 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 361.13953488
Subtract 344 from 360 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 361.13953488 with a remaining 1.6e-08.
