862087 ÷ 43 
The aim is to understand the frequency of 43 in 862087.

On to step 1:
If we divide 8 by 43, we get 0 and 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.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 43

Step 2:
86 divided by 43 is 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 86 from 86 leaves us with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 43

Step 3:
43 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 43

On to step 4:
The number 43 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 200.0
The remainder is 20 after subtracting 0 from 20.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 43

Moving on to step 5:
43 goes into 208 4 times with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 2004.0
Subtract 172 from 208 to get 36.
Take the next digit (7) from the dividend and append it to 36, then repeat: 367 / 43

Going ahead to step 6:
43 can be fit into 367 8 times, resulting in a remainder of 23.
The number 8 becomes the next digit in our result. 
Result so far: 20048.0
If we take 344 away from 367, 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.

Going ahead to step 7:
230 divided by 43 is 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 20048.5
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.

Going ahead to step 8:
When dividing 150 by 43, we get 3 with a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 20048.53
If we subtract 129 from 150, we get 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 9:
The number 43 fits into 210 4 times, leaving a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 20048.534
The remainder is 38 after subtracting 172 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 10:
43 can be fit into 380 8 times, resulting in a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 20048.5348
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.

Step 11:
The number 43 fits into 360 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 20048.53488
If we subtract 344 from 360, we 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.

The final outcome is 20048.53488, with a leftover of 1.6e-05.
