Let's divide 221377 by 43
The aim is to understand the frequency of 43 in 221377.

Moving on to step 1:
When dividing 2 by 43, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 43

On to step 2:
The number 43 fits into 22 0 times, leaving a remainder of 22.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 22, we get 22.
Include the next digit (1) from the dividend after 22, then repeat: 221 / 43

Advancing to step 3:
221 divided by 43 is 5 with a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 215 from 221 to get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 43

Going ahead to step 4:
When dividing 63 by 43, we get 1 with a remainder of 20.
The next digit of our result is 1. 
Result so far: 51.0
If we take 43 away from 63, we end up with 20.
Include the next digit (7) from the dividend after 20, then repeat: 207 / 43

Step 5:
The number 43 fits into 207 4 times, leaving a remainder of 35.
Record the quotient 4 as the next digit in the result. 
Result so far: 514.0
If we take 172 away from 207, we end up with 35.
Append the next digit (7) from the dividend to 35 and continue with: 357 / 43

Step 6:
When dividing 357 by 43, we get 8 with a remainder of 13.
The next digit of our result is 8. 
Result so far: 5148.0
If we subtract 344 from 357, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
If we divide 130 by 43, we get 3 and a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 5148.3
If we take 129 away from 130, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 8:
When dividing 10 by 43, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 5148.3
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
When dividing 100 by 43, we get 2 with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 5148.302
If we take 86 away from 100, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 10:
43 can be fit into 140 3 times, resulting in a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 5148.3023
If we take 129 away from 140, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 11:
The number 43 fits into 110 2 times, leaving a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 5148.30232
The remainder is 24 after subtracting 86 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
If we divide 240 by 43, we get 5 and a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 5148.302325
If we take 215 away from 240, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 13:
When dividing 250 by 43, we get 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 5148.3023255
Subtracting 215 from 250 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 5148.3023255 with a remainder of 3.5e-07.
