We divide 686901 by 43
The aim is to understand the frequency of 43 in 686901.

Step 1:
If we divide 6 by 43, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 43

Step 2:
43 goes into 68 1 times with a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 25 after subtracting 43 from 68.
Grab the next digit (6) from the dividend, add it to 25, then carry on: 256 / 43

On to step 3:
The number 43 fits into 256 5 times, leaving a remainder of 41.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 215 away from 256, we end up with 41.
Bring next digit (9) of the dividend behind the 41 and repeat the process: 419 / 43

Going ahead to step 4:
When dividing 419 by 43, we get 9 with a remainder of 32.
Put 9 as the next digit of the answer. 
Result so far: 159.0
Subtracting 387 from 419 leaves us with 32.
Take the next digit (0) from the dividend and append it to 32, then repeat: 320 / 43

On to step 5:
The number 43 fits into 320 7 times, leaving a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 1597.0
If we take 301 away from 320, we end up with 19.
Take the next digit (1) from the dividend and append it to 19, then repeat: 191 / 43

Advancing to step 6:
The number 43 fits into 191 4 times, leaving a remainder of 19.
Use 4 as the next digit of our solution. 
Result so far: 15974.0
Deduct 172 from 191 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
190 divided by 43 is 4 with a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 15974.4
If we take 172 away from 190, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
If we divide 180 by 43, we get 4 and a remainder of 8.
The next digit of our result is 4. 
Result so far: 15974.44
Subtracting 172 from 180 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 15974.44 with a remaining 0.008.
