We look at the division of 50155930 by 754 
The aim is to understand the frequency of 754 in 50155930.

On to step 1:
754 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 754

Going ahead to step 2:
The number 754 fits into 50 0 times, leaving a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 50, we end up with 50.
Grab the next digit (1) from the dividend, add it to 50, then carry on: 501 / 754

On to step 3:
The number 754 fits into 501 0 times, leaving a remainder of 501.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 501, we get 501.
Include the next digit (5) from the dividend after 501, then repeat: 5015 / 754

Going ahead to step 4:
The number 754 fits into 5015 6 times, leaving a remainder of 491.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 4524 from 5015, we get 491.
Grab the next digit (5) from the dividend, add it to 491, then carry on: 4915 / 754

Advancing to step 5:
754 can be fit into 4915 6 times, resulting in a remainder of 391.
The next digit of our result is 6. 
Result so far: 66.0
The remainder is 391 after subtracting 4524 from 4915.
Grab the next digit (9) from the dividend, add it to 391, then carry on: 3919 / 754

On to step 6:
If we divide 3919 by 754, we get 5 and a remainder of 149.
The next digit of our result is 5. 
Result so far: 665.0
Subtract 3770 from 3919 to get 149.
Grab the next digit (3) from the dividend, add it to 149, then carry on: 1493 / 754

Going ahead to step 7:
The number 754 fits into 1493 1 times, leaving a remainder of 739.
Record the quotient 1 as the next digit in the result. 
Result so far: 6651.0
Subtract 754 from 1493 to get 739.
Append the next digit (0) from the dividend to 739 and continue with: 7390 / 754

Moving on to step 8:
7390 divided by 754 is 9 with a remainder of 604.
The number 9 becomes the next digit in our result. 
Result so far: 66519.0
Deduct 6786 from 7390 and we're left with 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Advancing to step 9:
If we divide 6040 by 754, we get 8 and a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 66519.8
The remainder is 8 after subtracting 6032 from 6040.
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 10:
80 divided by 754 is 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 66519.8
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 11:
If we divide 800 by 754, we get 1 and a remainder of 46.
Put 1 as the next digit of the answer. 
Result so far: 66519.801
Deduct 754 from 800 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 12:
If we divide 460 by 754, we get 0 and a remainder of 460.
The next digit of our result is 0. 
Result so far: 66519.801
If we subtract 0 from 460, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Moving on to step 13:
The number 754 fits into 4600 6 times, leaving a remainder of 76.
The number 6 becomes the next digit in our result. 
Result so far: 66519.80106
If we take 4524 away from 4600, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 14:
754 can be fit into 760 1 times, resulting in a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 66519.801061
If we take 754 away from 760, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 15:
If we divide 60 by 754, we get 0 and a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 66519.801061
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 16:
600 divided by 754 is 0 with a remainder of 600.
The next digit of our result is 0. 
Result so far: 66519.801061
If we take 0 away from 600, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The final result is 66519.801061 with a remainder of 6e-07.
