Let's divide 637371 by 43
The aim is to understand the frequency of 43 in 637371.

On to step 1:
43 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 43

Going ahead to step 2:
43 can be fit into 63 1 times, resulting in a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 43 from 63 leaves us with 20.
Append the next digit (7) from the dividend to 20 and continue with: 207 / 43

On to step 3:
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: 14.0
The remainder is 35 after subtracting 172 from 207.
Append the next digit (3) from the dividend to 35 and continue with: 353 / 43

On to step 4:
When dividing 353 by 43, we get 8 with a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 148.0
Deduct 344 from 353 and we're left with 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 43

Going ahead to step 5:
43 goes into 97 2 times with a remainder of 11.
The next digit of our result is 2. 
Result so far: 1482.0
Deduct 86 from 97 and we're left with 11.
Fetch the next digit (1) from the dividend, attach it to 11 and continue: 111 / 43

Let's proceed to step 6:
The number 43 fits into 111 2 times, leaving a remainder of 25.
Record the quotient 2 as the next digit in the result. 
Result so far: 14822.0
Subtract 86 from 111 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.

Moving on to step 7:
The number 43 fits into 250 5 times, leaving a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 14822.5
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.

Step 8:
When dividing 350 by 43, we get 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 14822.58
Subtract 344 from 350 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 9:
43 can be fit into 60 1 times, resulting in a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 14822.581
Deduct 43 from 60 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 10:
43 goes into 170 3 times with a remainder of 41.
Record the quotient 3 as the next digit in the result. 
Result so far: 14822.5813
If we take 129 away from 170, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 11:
The number 43 fits into 410 9 times, leaving a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 14822.58139
If we subtract 387 from 410, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 12:
When dividing 230 by 43, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 14822.581395
The remainder is 15 after subtracting 215 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 13:
43 goes into 150 3 times with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 14822.5813953
The remainder is 21 after subtracting 129 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 14:
43 goes into 210 4 times with a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 14822.58139534
Deduct 172 from 210 and we're left 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.

The quotient of the division is 14822.58139534, and the remainder is 3.8e-08.
