Let's divide 258591 by 76
The aim is to understand the frequency of 76 in 258591.

Let's proceed to step 1:
The number 76 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 76

Moving on to step 2:
The number 76 fits into 25 0 times, leaving a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Grab the next digit (8) from the dividend, add it to 25, then carry on: 258 / 76

Let's proceed to step 3:
The number 76 fits into 258 3 times, leaving a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 228 from 258 to get 30.
Bring next digit (5) of the dividend behind the 30 and repeat the process: 305 / 76

Step 4:
When dividing 305 by 76, we get 4 with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
Subtract 304 from 305 to get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 76

Step 5:
When dividing 19 by 76, we get 0 with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 340.0
Deduct 0 from 19 and we're left with 19.
Append the next digit (1) from the dividend to 19 and continue with: 191 / 76

Moving on to step 6:
The number 76 fits into 191 2 times, leaving a remainder of 39.
Use 2 as the next digit of our solution. 
Result so far: 3402.0
Deduct 152 from 191 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 7:
If we divide 390 by 76, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 3402.5
If we subtract 380 from 390, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
76 goes into 100 1 times with a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 3402.51
The remainder is 24 after subtracting 76 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 9:
76 goes into 240 3 times with a remainder of 12.
The next digit of our result is 3. 
Result so far: 3402.513
Subtract 228 from 240 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
120 divided by 76 is 1 with a remainder of 44.
Write down 1 as next digit of the result. 
Result so far: 3402.5131
Subtract 76 from 120 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 11:
76 goes into 440 5 times with a remainder of 60.
The next digit of our result is 5. 
Result so far: 3402.51315
If we subtract 380 from 440, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 12:
76 can be fit into 600 7 times, resulting in a remainder of 68.
The number 7 becomes the next digit in our result. 
Result so far: 3402.513157
Subtract 532 from 600 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 13:
76 goes into 680 8 times with a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 3402.5131578
Deduct 608 from 680 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 14:
76 goes into 720 9 times with a remainder of 36.
Write down 9 as next digit of the result. 
Result so far: 3402.51315789
Subtract 684 from 720 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final result is 3402.51315789 with a remainder of 3.6e-08.
