We're dividing 58641035 by 754 
The aim is to understand the frequency of 754 in 58641035.

Step 1:
When dividing 5 by 754, we get 0 with 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.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 754

On to step 2:
The number 754 fits into 58 0 times, leaving a remainder of 58.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 58 and we're left with 58.
Append the next digit (6) from the dividend to 58 and continue with: 586 / 754

Let's proceed to step 3:
754 can be fit into 586 0 times, resulting in a remainder of 586.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 586 to get 586.
Bring next digit (4) of the dividend behind the 586 and repeat the process: 5864 / 754

Advancing to step 4:
5864 divided by 754 is 7 with a remainder of 586.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 586 after subtracting 5278 from 5864.
Bring next digit (1) of the dividend behind the 586 and repeat the process: 5861 / 754

Moving on to step 5:
If we divide 5861 by 754, we get 7 and a remainder of 583.
The number 7 becomes the next digit in our result. 
Result so far: 77.0
Deduct 5278 from 5861 and we're left with 583.
Take the next digit (0) from the dividend and append it to 583, then repeat: 5830 / 754

On to step 6:
If we divide 5830 by 754, we get 7 and a remainder of 552.
Record the quotient 7 as the next digit in the result. 
Result so far: 777.0
If we subtract 5278 from 5830, we get 552.
Grab the next digit (3) from the dividend, add it to 552, then carry on: 5523 / 754

Advancing to step 7:
When dividing 5523 by 754, we get 7 with a remainder of 245.
Use 7 as the next digit of our solution. 
Result so far: 7777.0
Subtracting 5278 from 5523 leaves us with 245.
Append the next digit (5) from the dividend to 245 and continue with: 2455 / 754

Moving on to step 8:
754 goes into 2455 3 times with a remainder of 193.
The next digit of our result is 3. 
Result so far: 77773.0
The remainder is 193 after subtracting 2262 from 2455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Let's proceed to step 9:
If we divide 1930 by 754, we get 2 and a remainder of 422.
Put 2 as the next digit of the answer. 
Result so far: 77773.2
Deduct 1508 from 1930 and we're left with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Moving on to step 10:
When dividing 4220 by 754, we get 5 with a remainder of 450.
Record the quotient 5 as the next digit in the result. 
Result so far: 77773.25
Subtract 3770 from 4220 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 11:
If we divide 4500 by 754, we get 5 and a remainder of 730.
The number 5 becomes the next digit in our result. 
Result so far: 77773.255
If we subtract 3770 from 4500, we get 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

The final result is 77773.255 with a remainder of 0.073.
