We're dividing 621062 by 43 
The aim is to understand the frequency of 43 in 621062.

Going ahead to step 1:
The number 43 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 43

Step 2:
43 can be fit into 62 1 times, resulting in a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 43 from 62 leaves us with 19.
Append the next digit (1) from the dividend to 19 and continue with: 191 / 43

Let's proceed to step 3:
When dividing 191 by 43, we get 4 with a remainder of 19.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtracting 172 from 191 leaves us with 19.
Grab the next digit (0) from the dividend, add it to 19, then carry on: 190 / 43

Let's proceed to step 4:
When dividing 190 by 43, we get 4 with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 144.0
If we take 172 away from 190, we end up with 18.
Append the next digit (6) from the dividend to 18 and continue with: 186 / 43

Step 5:
43 can be fit into 186 4 times, resulting in a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 1444.0
Subtract 172 from 186 to get 14.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 43

Let's proceed to step 6:
The number 43 fits into 142 3 times, leaving a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 14443.0
Subtracting 129 from 142 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
If we divide 130 by 43, we get 3 and a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 14443.3
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.

Going ahead to step 8:
The number 43 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 14443.3
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
The number 43 fits into 100 2 times, leaving a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 14443.302
If we subtract 86 from 100, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 10:
When dividing 140 by 43, we get 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 14443.3023
If we subtract 129 from 140, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 11:
43 goes into 110 2 times with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 14443.30232
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.

Moving on to step 12:
43 can be fit into 240 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 14443.302325
Subtract 215 from 240 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed 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: 14443.3023255
If we take 215 away from 250, we end up 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.

After the division, we end up with 14443.3023255 and a remainder of 3.5e-07.
