We're dividing 39438975 by 127 
The aim is to understand the frequency of 127 in 39438975.

On to step 1:
The number 127 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 127

Step 2:
If we divide 39 by 127, we get 0 and a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Append the next digit (4) from the dividend to 39 and continue with: 394 / 127

Let's proceed to step 3:
When dividing 394 by 127, we get 3 with a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 381 from 394 and we're left with 13.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 127

Moving on to step 4:
When dividing 133 by 127, we get 1 with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Deduct 127 from 133 and we're left with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 127

Step 5:
When dividing 68 by 127, we get 0 with a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 310.0
The remainder is 68 after subtracting 0 from 68.
Append the next digit (9) from the dividend to 68 and continue with: 689 / 127

Let's proceed to step 6:
127 goes into 689 5 times with a remainder of 54.
Use 5 as the next digit of our solution. 
Result so far: 3105.0
The remainder is 54 after subtracting 635 from 689.
Grab the next digit (7) from the dividend, add it to 54, then carry on: 547 / 127

Moving on to step 7:
547 divided by 127 is 4 with a remainder of 39.
Record the quotient 4 as the next digit in the result. 
Result so far: 31054.0
Subtracting 508 from 547 leaves us with 39.
Append the next digit (5) from the dividend to 39 and continue with: 395 / 127

On to step 8:
395 divided by 127 is 3 with a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 310543.0
The remainder is 14 after subtracting 381 from 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
If we divide 140 by 127, we get 1 and a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 310543.1
Subtract 127 from 140 to 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.

Advancing to step 10:
The number 127 fits into 130 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 310543.11
Subtracting 127 from 130 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The quotient of the division is 310543.11, and the remainder is 0.003.
