42645261 ÷ 755 
The aim is to understand the frequency of 755 in 42645261.

Moving on to step 1:
The number 755 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 755

Moving on to step 2:
755 goes into 42 0 times with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Append the next digit (6) from the dividend to 42 and continue with: 426 / 755

Step 3:
426 divided by 755 is 0 with a remainder of 426.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 426 and we're left with 426.
Grab the next digit (4) from the dividend, add it to 426, then carry on: 4264 / 755

Going ahead to step 4:
755 goes into 4264 5 times with a remainder of 489.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 3775 from 4264 and we're left with 489.
Grab the next digit (5) from the dividend, add it to 489, then carry on: 4895 / 755

Going ahead to step 5:
4895 divided by 755 is 6 with a remainder of 365.
Use 6 as the next digit of our solution. 
Result so far: 56.0
Subtract 4530 from 4895 to get 365.
Include the next digit (2) from the dividend after 365, then repeat: 3652 / 755

Let's proceed to step 6:
If we divide 3652 by 755, we get 4 and a remainder of 632.
The number 4 becomes the next digit in our result. 
Result so far: 564.0
If we subtract 3020 from 3652, we get 632.
Include the next digit (6) from the dividend after 632, then repeat: 6326 / 755

Let's proceed to step 7:
If we divide 6326 by 755, we get 8 and a remainder of 286.
Use 8 as the next digit of our solution. 
Result so far: 5648.0
If we take 6040 away from 6326, we end up with 286.
Bring next digit (1) of the dividend behind the 286 and repeat the process: 2861 / 755

On to step 8:
2861 divided by 755 is 3 with a remainder of 596.
The number 3 becomes the next digit in our result. 
Result so far: 56483.0
Subtracting 2265 from 2861 leaves us with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Step 9:
755 can be fit into 5960 7 times, resulting in a remainder of 675.
Record the quotient 7 as the next digit in the result. 
Result so far: 56483.7
If we take 5285 away from 5960, we end up with 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

Advancing to step 10:
The number 755 fits into 6750 8 times, leaving a remainder of 710.
Record the quotient 8 as the next digit in the result. 
Result so far: 56483.78
If we subtract 6040 from 6750, we get 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Advancing to step 11:
7100 divided by 755 is 9 with a remainder of 305.
Use 9 as the next digit of our solution. 
Result so far: 56483.789
The remainder is 305 after subtracting 6795 from 7100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Going ahead to step 12:
The number 755 fits into 3050 4 times, leaving a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 56483.7894
If we take 3020 away from 3050, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 13:
755 can be fit into 300 0 times, resulting in a remainder of 300.
Write down 0 as next digit of the result. 
Result so far: 56483.7894
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 14:
When dividing 3000 by 755, we get 3 with a remainder of 735.
Use 3 as the next digit of our solution. 
Result so far: 56483.789403
The remainder is 735 after subtracting 2265 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7350, and continue the process.

Let's proceed to step 15:
7350 divided by 755 is 9 with a remainder of 555.
Put 9 as the next digit of the answer. 
Result so far: 56483.7894039
Deduct 6795 from 7350 and we're left with 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Going ahead to step 16:
5550 divided by 755 is 7 with a remainder of 265.
The number 7 becomes the next digit in our result. 
Result so far: 56483.78940397
Subtracting 5285 from 5550 leaves us with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Our division results in 56483.78940397 with a remaining 2.65e-07.
