577806 ÷ 43 
The aim is to understand the frequency of 43 in 577806.

Going ahead to step 1:
5 divided by 43 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 43

Going ahead to step 2:
43 can be fit into 57 1 times, resulting in a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 43 from 57 to get 14.
Grab the next digit (7) from the dividend, add it to 14, then carry on: 147 / 43

Let's proceed to step 3:
The number 43 fits into 147 3 times, leaving a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 129 from 147 leaves us with 18.
Bring next digit (8) of the dividend behind the 18 and repeat the process: 188 / 43

Going ahead to step 4:
When dividing 188 by 43, we get 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 134.0
Subtract 172 from 188 to get 16.
Grab the next digit (0) from the dividend, add it to 16, then carry on: 160 / 43

Moving on to step 5:
43 can be fit into 160 3 times, resulting in a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 1343.0
If we subtract 129 from 160, we get 31.
Bring next digit (6) of the dividend behind the 31 and repeat the process: 316 / 43

Step 6:
When dividing 316 by 43, we get 7 with a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 13437.0
Subtract 301 from 316 to 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 7:
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: 13437.3
Deduct 129 from 150 and we're left 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.

Advancing to step 8:
When dividing 210 by 43, we get 4 with a remainder of 38.
Write down 4 as next digit of the result. 
Result so far: 13437.34
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.

On to step 9:
380 divided by 43 is 8 with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 13437.348
Deduct 344 from 380 and we're left 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.

Advancing to step 10:
43 can be fit into 360 8 times, resulting in a remainder of 16.
The next digit of our result is 8. 
Result so far: 13437.3488
Deduct 344 from 360 and we're left with 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 13437.3488 with a remaining 0.00016.
