525445 ÷ 43 
The aim is to understand the frequency of 43 in 525445.

Moving on to step 1:
43 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 43

Going ahead to step 2:
52 divided by 43 is 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 43 from 52 and we're left with 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 43

Going ahead to step 3:
If we divide 95 by 43, we get 2 and a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 86 from 95 to get 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 43

Step 4:
If we divide 94 by 43, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 122.0
Subtracting 86 from 94 leaves us with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 43

Advancing to step 5:
43 goes into 84 1 times with a remainder of 41.
Write down 1 as next digit of the result. 
Result so far: 1221.0
The remainder is 41 after subtracting 43 from 84.
Fetch the next digit (5) from the dividend, attach it to 41 and continue: 415 / 43

Going ahead to step 6:
When dividing 415 by 43, we get 9 with a remainder of 28.
Write down 9 as next digit of the result. 
Result so far: 12219.0
The remainder is 28 after subtracting 387 from 415.
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 7:
280 divided by 43 is 6 with a remainder of 22.
The next digit of our result is 6. 
Result so far: 12219.6
If we subtract 258 from 280, we 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.

Going ahead to step 8:
When dividing 220 by 43, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 12219.65
If we subtract 215 from 220, we 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.

Step 9:
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: 12219.651
If we take 43 away from 50, we end up with 7.
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 10:
The number 43 fits into 70 1 times, leaving a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 12219.6511
Subtract 43 from 70 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

After the division, we end up with 12219.6511 and a remainder of 0.00027.
