We look at the division of 78958434 by 754 
The aim is to understand the frequency of 754 in 78958434.

Advancing to step 1:
If we divide 7 by 754, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 754

Let's proceed to step 2:
754 goes into 78 0 times with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Bring next digit (9) of the dividend behind the 78 and repeat the process: 789 / 754

Moving on to step 3:
789 divided by 754 is 1 with a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 754 away from 789, we end up with 35.
Append the next digit (5) from the dividend to 35 and continue with: 355 / 754

Moving on to step 4:
If we divide 355 by 754, we get 0 and a remainder of 355.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 355 leaves us with 355.
Append the next digit (8) from the dividend to 355 and continue with: 3558 / 754

Moving on to step 5:
754 can be fit into 3558 4 times, resulting in a remainder of 542.
The number 4 becomes the next digit in our result. 
Result so far: 104.0
If we take 3016 away from 3558, we end up with 542.
Include the next digit (4) from the dividend after 542, then repeat: 5424 / 754

Moving on to step 6:
754 can be fit into 5424 7 times, resulting in a remainder of 146.
Write down 7 as next digit of the result. 
Result so far: 1047.0
If we subtract 5278 from 5424, we get 146.
Bring next digit (3) of the dividend behind the 146 and repeat the process: 1463 / 754

Advancing to step 7:
754 can be fit into 1463 1 times, resulting in a remainder of 709.
Use 1 as the next digit of our solution. 
Result so far: 10471.0
Subtract 754 from 1463 to get 709.
Grab the next digit (4) from the dividend, add it to 709, then carry on: 7094 / 754

Moving on to step 8:
754 can be fit into 7094 9 times, resulting in a remainder of 308.
Use 9 as the next digit of our solution. 
Result so far: 104719.0
Subtracting 6786 from 7094 leaves us with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Step 9:
When dividing 3080 by 754, we get 4 with a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 104719.4
Subtracting 3016 from 3080 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 10:
The number 754 fits into 640 0 times, leaving a remainder of 640.
The next digit of our result is 0. 
Result so far: 104719.4
Subtracting 0 from 640 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

On to step 11:
The number 754 fits into 6400 8 times, leaving a remainder of 368.
Put 8 as the next digit of the answer. 
Result so far: 104719.408
Deduct 6032 from 6400 and we're left with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Step 12:
754 goes into 3680 4 times with a remainder of 664.
Use 4 as the next digit of our solution. 
Result so far: 104719.4084
The remainder is 664 after subtracting 3016 from 3680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

Step 13:
6640 divided by 754 is 8 with a remainder of 608.
Use 8 as the next digit of our solution. 
Result so far: 104719.40848
If we subtract 6032 from 6640, we get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Going ahead to step 14:
The number 754 fits into 6080 8 times, leaving a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 104719.408488
Deduct 6032 from 6080 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 104719.408488 and a remainder of 4.8e-06.
