30901228 ÷ 763 
The aim is to understand the frequency of 763 in 30901228.

Let's proceed to step 1:
If we divide 3 by 763, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 763

Moving on to step 2:
When dividing 30 by 763, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Grab the next digit (9) from the dividend, add it to 30, then carry on: 309 / 763

Let's proceed to step 3:
309 divided by 763 is 0 with a remainder of 309.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 309 after subtracting 0 from 309.
Append the next digit (0) from the dividend to 309 and continue with: 3090 / 763

Step 4:
The number 763 fits into 3090 4 times, leaving a remainder of 38.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 3052 from 3090 and we're left with 38.
Take the next digit (1) from the dividend and append it to 38, then repeat: 381 / 763

Moving on to step 5:
The number 763 fits into 381 0 times, leaving a remainder of 381.
The next digit of our result is 0. 
Result so far: 40.0
Subtract 0 from 381 to get 381.
Take the next digit (2) from the dividend and append it to 381, then repeat: 3812 / 763

Let's proceed to step 6:
When dividing 3812 by 763, we get 4 with a remainder of 760.
The number 4 becomes the next digit in our result. 
Result so far: 404.0
Deduct 3052 from 3812 and we're left with 760.
Take the next digit (2) from the dividend and append it to 760, then repeat: 7602 / 763

On to step 7:
The number 763 fits into 7602 9 times, leaving a remainder of 735.
Use 9 as the next digit of our solution. 
Result so far: 4049.0
Subtracting 6867 from 7602 leaves us with 735.
Take the next digit (8) from the dividend and append it to 735, then repeat: 7358 / 763

Going ahead to step 8:
If we divide 7358 by 763, we get 9 and a remainder of 491.
The next digit of our result is 9. 
Result so far: 40499.0
The remainder is 491 after subtracting 6867 from 7358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Step 9:
The number 763 fits into 4910 6 times, leaving a remainder of 332.
Write down 6 as next digit of the result. 
Result so far: 40499.6
Subtract 4578 from 4910 to get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Advancing to step 10:
763 goes into 3320 4 times with a remainder of 268.
Write down 4 as next digit of the result. 
Result so far: 40499.64
Subtracting 3052 from 3320 leaves us with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Advancing to step 11:
763 goes into 2680 3 times with a remainder of 391.
Record the quotient 3 as the next digit in the result. 
Result so far: 40499.643
Subtract 2289 from 2680 to get 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Advancing to step 12:
763 can be fit into 3910 5 times, resulting in a remainder of 95.
The next digit of our result is 5. 
Result so far: 40499.6435
If we take 3815 away from 3910, we end up with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 13:
763 can be fit into 950 1 times, resulting in a remainder of 187.
Use 1 as the next digit of our solution. 
Result so far: 40499.64351
Subtract 763 from 950 to get 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Let's proceed to step 14:
When dividing 1870 by 763, we get 2 with a remainder of 344.
Write down 2 as next digit of the result. 
Result so far: 40499.643512
Subtracting 1526 from 1870 leaves us with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Advancing to step 15:
The number 763 fits into 3440 4 times, leaving a remainder of 388.
Record the quotient 4 as the next digit in the result. 
Result so far: 40499.6435124
Deduct 3052 from 3440 and we're left with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Advancing to step 16:
3880 divided by 763 is 5 with a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 40499.64351245
If we take 3815 away from 3880, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

In conclusion, the division gives 40499.64351245 with a balance of 6.5e-08.
