We look at the division of 51874174 by 754 
The aim is to understand the frequency of 754 in 51874174.

Let's proceed to step 1:
If we divide 5 by 754, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 754

Step 2:
The number 754 fits into 51 0 times, leaving a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Include the next digit (8) from the dividend after 51, then repeat: 518 / 754

Moving on to step 3:
754 can be fit into 518 0 times, resulting in a remainder of 518.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 518 after subtracting 0 from 518.
Bring next digit (7) of the dividend behind the 518 and repeat the process: 5187 / 754

Step 4:
754 goes into 5187 6 times with a remainder of 663.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 663 after subtracting 4524 from 5187.
Fetch the next digit (4) from the dividend, attach it to 663 and continue: 6634 / 754

On to step 5:
6634 divided by 754 is 8 with a remainder of 602.
Record the quotient 8 as the next digit in the result. 
Result so far: 68.0
The remainder is 602 after subtracting 6032 from 6634.
Append the next digit (1) from the dividend to 602 and continue with: 6021 / 754

On to step 6:
754 can be fit into 6021 7 times, resulting in a remainder of 743.
Use 7 as the next digit of our solution. 
Result so far: 687.0
Subtracting 5278 from 6021 leaves us with 743.
Grab the next digit (7) from the dividend, add it to 743, then carry on: 7437 / 754

Advancing to step 7:
754 goes into 7437 9 times with a remainder of 651.
The next digit of our result is 9. 
Result so far: 6879.0
Subtracting 6786 from 7437 leaves us with 651.
Include the next digit (4) from the dividend after 651, then repeat: 6514 / 754

On to step 8:
754 can be fit into 6514 8 times, resulting in a remainder of 482.
Record the quotient 8 as the next digit in the result. 
Result so far: 68798.0
Subtracting 6032 from 6514 leaves us with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Let's proceed to step 9:
754 can be fit into 4820 6 times, resulting in a remainder of 296.
The next digit of our result is 6. 
Result so far: 68798.6
Deduct 4524 from 4820 and we're left with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Advancing to step 10:
If we divide 2960 by 754, we get 3 and a remainder of 698.
Use 3 as the next digit of our solution. 
Result so far: 68798.63
Subtracting 2262 from 2960 leaves us with 698.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6980, and continue the process.

Step 11:
754 can be fit into 6980 9 times, resulting in a remainder of 194.
Use 9 as the next digit of our solution. 
Result so far: 68798.639
Subtracting 6786 from 6980 leaves us with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Moving on to step 12:
754 goes into 1940 2 times with a remainder of 432.
The number 2 becomes the next digit in our result. 
Result so far: 68798.6392
Subtracting 1508 from 1940 leaves us with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Step 13:
When dividing 4320 by 754, we get 5 with a remainder of 550.
The number 5 becomes the next digit in our result. 
Result so far: 68798.63925
Deduct 3770 from 4320 and we're left with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Moving on to step 14:
754 can be fit into 5500 7 times, resulting in a remainder of 222.
Use 7 as the next digit of our solution. 
Result so far: 68798.639257
Subtract 5278 from 5500 to get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Advancing to step 15:
When dividing 2220 by 754, we get 2 with a remainder of 712.
Write down 2 as next digit of the result. 
Result so far: 68798.6392572
The remainder is 712 after subtracting 1508 from 2220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

Moving on to step 16:
If we divide 7120 by 754, we get 9 and a remainder of 334.
Write down 9 as next digit of the result. 
Result so far: 68798.63925729
If we take 6786 away from 7120, we end up with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

After the division, we end up with 68798.63925729 and a remainder of 3.34e-07.
