We look at the division of 637200 by 41 
The aim is to understand the frequency of 41 in 637200.

Step 1:
When dividing 6 by 41, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 41

On to step 2:
63 divided by 41 is 1 with a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 41 from 63 leaves us with 22.
Take the next digit (7) from the dividend and append it to 22, then repeat: 227 / 41

Moving on to step 3:
When dividing 227 by 41, we get 5 with a remainder of 22.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 205 away from 227, we end up with 22.
Fetch the next digit (2) from the dividend, attach it to 22 and continue: 222 / 41

On to step 4:
222 divided by 41 is 5 with a remainder of 17.
The number 5 becomes the next digit in our result. 
Result so far: 155.0
Subtracting 205 from 222 leaves us with 17.
Bring next digit (0) of the dividend behind the 17 and repeat the process: 170 / 41

On to step 5:
The number 41 fits into 170 4 times, leaving a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 1554.0
Subtract 164 from 170 to get 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 41

Step 6:
41 goes into 60 1 times with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 15541.0
Deduct 41 from 60 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.

On to step 7:
When dividing 190 by 41, we get 4 with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 15541.4
Subtract 164 from 190 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 8:
41 can be fit into 260 6 times, resulting in a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 15541.46
The remainder is 14 after subtracting 246 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 9:
The number 41 fits into 140 3 times, leaving a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 15541.463
The remainder is 17 after subtracting 123 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 10:
If we divide 170 by 41, we get 4 and a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 15541.4634
Subtract 164 from 170 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.

On to step 11:
The number 41 fits into 60 1 times, leaving a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 15541.46341
Subtracting 41 from 60 leaves us 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.

Moving on to step 12:
190 divided by 41 is 4 with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 15541.463414
If we take 164 away from 190, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 13:
If we divide 260 by 41, we get 6 and a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 15541.4634146
Deduct 246 from 260 and we're left 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.

Going ahead to step 14:
If we divide 140 by 41, we get 3 and a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 15541.46341463
The remainder is 17 after subtracting 123 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The quotient of the division is 15541.46341463, and the remainder is 1.7e-08.
