40257970 divided by 103 
The aim is to understand the frequency of 103 in 40257970.

Step 1:
103 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 103

Advancing to step 2:
If we divide 40 by 103, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Fetch the next digit (2) from the dividend, attach it to 40 and continue: 402 / 103

Advancing to step 3:
103 goes into 402 3 times with a remainder of 93.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 309 from 402 and we're left with 93.
Append the next digit (5) from the dividend to 93 and continue with: 935 / 103

Moving on to step 4:
935 divided by 103 is 9 with a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 39.0
Subtracting 927 from 935 leaves us with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 103

Going ahead to step 5:
When dividing 87 by 103, we get 0 with a remainder of 87.
The next digit of our result is 0. 
Result so far: 390.0
Deduct 0 from 87 and we're left with 87.
Append the next digit (9) from the dividend to 87 and continue with: 879 / 103

Let's proceed to step 6:
The number 103 fits into 879 8 times, leaving a remainder of 55.
Put 8 as the next digit of the answer. 
Result so far: 3908.0
Subtracting 824 from 879 leaves us with 55.
Fetch the next digit (7) from the dividend, attach it to 55 and continue: 557 / 103

Going ahead to step 7:
When dividing 557 by 103, we get 5 with a remainder of 42.
Write down 5 as next digit of the result. 
Result so far: 39085.0
The remainder is 42 after subtracting 515 from 557.
Fetch the next digit (0) from the dividend, attach it to 42 and continue: 420 / 103

Advancing to step 8:
The number 103 fits into 420 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 390854.0
Subtract 412 from 420 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
80 divided by 103 is 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 390854.0
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 10:
The number 103 fits into 800 7 times, leaving a remainder of 79.
Record the quotient 7 as the next digit in the result. 
Result so far: 390854.07
If we subtract 721 from 800, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 11:
If we divide 790 by 103, we get 7 and a remainder of 69.
Record the quotient 7 as the next digit in the result. 
Result so far: 390854.077
Subtracting 721 from 790 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

After the division, we end up with 390854.077 and a remainder of 0.0069.
