30663071 ÷ 755 
The aim is to understand the frequency of 755 in 30663071.

On to step 1:
If we divide 3 by 755, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 755

Step 2:
If we divide 30 by 755, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Grab the next digit (6) from the dividend, add it to 30, then carry on: 306 / 755

Going ahead to step 3:
306 divided by 755 is 0 with a remainder of 306.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 306 leaves us with 306.
Bring next digit (6) of the dividend behind the 306 and repeat the process: 3066 / 755

Step 4:
755 goes into 3066 4 times with a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 3020 from 3066, we get 46.
Fetch the next digit (3) from the dividend, attach it to 46 and continue: 463 / 755

Going ahead to step 5:
755 goes into 463 0 times with a remainder of 463.
The next digit of our result is 0. 
Result so far: 40.0
Subtracting 0 from 463 leaves us with 463.
Take the next digit (0) from the dividend and append it to 463, then repeat: 4630 / 755

Step 6:
755 goes into 4630 6 times with a remainder of 100.
Write down 6 as next digit of the result. 
Result so far: 406.0
Subtract 4530 from 4630 to get 100.
Grab the next digit (7) from the dividend, add it to 100, then carry on: 1007 / 755

Going ahead to step 7:
1007 divided by 755 is 1 with a remainder of 252.
Record the quotient 1 as the next digit in the result. 
Result so far: 4061.0
Subtracting 755 from 1007 leaves us with 252.
Append the next digit (1) from the dividend to 252 and continue with: 2521 / 755

On to step 8:
755 can be fit into 2521 3 times, resulting in a remainder of 256.
Use 3 as the next digit of our solution. 
Result so far: 40613.0
If we take 2265 away from 2521, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 9:
The number 755 fits into 2560 3 times, leaving a remainder of 295.
The next digit of our result is 3. 
Result so far: 40613.3
If we take 2265 away from 2560, we end up with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Advancing to step 10:
755 can be fit into 2950 3 times, resulting in a remainder of 685.
The next digit of our result is 3. 
Result so far: 40613.33
If we take 2265 away from 2950, we end up with 685.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

After the division, we end up with 40613.33 and a remainder of 0.685.
