10402213 divided by 755 
The aim is to understand the frequency of 755 in 10402213.

Advancing to step 1:
1 divided by 755 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 755

Moving on to step 2:
755 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 755

Step 3:
104 divided by 755 is 0 with a remainder of 104.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 104 and we're left with 104.
Append the next digit (0) from the dividend to 104 and continue with: 1040 / 755

Going ahead to step 4:
When dividing 1040 by 755, we get 1 with a remainder of 285.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 755 from 1040 to get 285.
Take the next digit (2) from the dividend and append it to 285, then repeat: 2852 / 755

Step 5:
The number 755 fits into 2852 3 times, leaving a remainder of 587.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we take 2265 away from 2852, we end up with 587.
Include the next digit (2) from the dividend after 587, then repeat: 5872 / 755

Going ahead to step 6:
When dividing 5872 by 755, we get 7 with a remainder of 587.
Use 7 as the next digit of our solution. 
Result so far: 137.0
Deduct 5285 from 5872 and we're left with 587.
Include the next digit (1) from the dividend after 587, then repeat: 5871 / 755

On to step 7:
5871 divided by 755 is 7 with a remainder of 586.
The next digit of our result is 7. 
Result so far: 1377.0
The remainder is 586 after subtracting 5285 from 5871.
Include the next digit (3) from the dividend after 586, then repeat: 5863 / 755

Going ahead to step 8:
5863 divided by 755 is 7 with a remainder of 578.
Record the quotient 7 as the next digit in the result. 
Result so far: 13777.0
Subtracting 5285 from 5863 leaves us with 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Going ahead to step 9:
If we divide 5780 by 755, we get 7 and a remainder of 495.
The number 7 becomes the next digit in our result. 
Result so far: 13777.7
The remainder is 495 after subtracting 5285 from 5780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Step 10:
755 can be fit into 4950 6 times, resulting in a remainder of 420.
Put 6 as the next digit of the answer. 
Result so far: 13777.76
If we subtract 4530 from 4950, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 11:
755 can be fit into 4200 5 times, resulting in a remainder of 425.
The next digit of our result is 5. 
Result so far: 13777.765
Deduct 3775 from 4200 and we're left with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Step 12:
755 goes into 4250 5 times with a remainder of 475.
Use 5 as the next digit of our solution. 
Result so far: 13777.7655
Subtract 3775 from 4250 to get 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

The final result is 13777.7655 with a remainder of 0.00475.
