864925 ÷ 43 
The aim is to understand the frequency of 43 in 864925.

Moving on to step 1:
8 divided by 43 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 43

Moving on to step 2:
86 divided by 43 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 86 from 86 to get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 43

Going ahead to step 3:
When dividing 4 by 43, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we take 0 away from 4, we end up with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 43

Moving on to step 4:
49 divided by 43 is 1 with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 201.0
Subtracting 43 from 49 leaves us with 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 43

Moving on to step 5:
If we divide 62 by 43, we get 1 and a remainder of 19.
The next digit of our result is 1. 
Result so far: 2011.0
Deduct 43 from 62 and we're left with 19.
Bring next digit (5) of the dividend behind the 19 and repeat the process: 195 / 43

Step 6:
43 goes into 195 4 times with a remainder of 23.
The number 4 becomes the next digit in our result. 
Result so far: 20114.0
If we take 172 away from 195, we end up 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.

Step 7:
If we divide 230 by 43, we get 5 and a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 20114.5
Deduct 215 from 230 and we're left with 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 8:
43 goes into 150 3 times with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 20114.53
The remainder is 21 after subtracting 129 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 9:
43 goes into 210 4 times with a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 20114.534
If we take 172 away from 210, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 10:
43 goes into 380 8 times with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 20114.5348
Subtract 344 from 380 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 11:
43 can be fit into 360 8 times, resulting in a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 20114.53488
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.

After the division, we end up with 20114.53488 and a remainder of 1.6e-05.
