30219530 ÷ 781 
The aim is to understand the frequency of 781 in 30219530.

Advancing to step 1:
The number 781 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 781

Advancing to step 2:
781 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Include the next digit (2) from the dividend after 30, then repeat: 302 / 781

On to step 3:
If we divide 302 by 781, we get 0 and a remainder of 302.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 302 after subtracting 0 from 302.
Append the next digit (1) from the dividend to 302 and continue with: 3021 / 781

Advancing to step 4:
If we divide 3021 by 781, we get 3 and a remainder of 678.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 2343 from 3021 to get 678.
Append the next digit (9) from the dividend to 678 and continue with: 6789 / 781

Moving on to step 5:
781 can be fit into 6789 8 times, resulting in a remainder of 541.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
If we take 6248 away from 6789, we end up with 541.
Include the next digit (5) from the dividend after 541, then repeat: 5415 / 781

Let's proceed to step 6:
781 goes into 5415 6 times with a remainder of 729.
The next digit of our result is 6. 
Result so far: 386.0
Deduct 4686 from 5415 and we're left with 729.
Include the next digit (3) from the dividend after 729, then repeat: 7293 / 781

Going ahead to step 7:
781 can be fit into 7293 9 times, resulting in a remainder of 264.
The number 9 becomes the next digit in our result. 
Result so far: 3869.0
Subtracting 7029 from 7293 leaves us with 264.
Include the next digit (0) from the dividend after 264, then repeat: 2640 / 781

Let's proceed to step 8:
If we divide 2640 by 781, we get 3 and a remainder of 297.
Write down 3 as next digit of the result. 
Result so far: 38693.0
Subtracting 2343 from 2640 leaves us with 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Advancing to step 9:
The number 781 fits into 2970 3 times, leaving a remainder of 627.
Write down 3 as next digit of the result. 
Result so far: 38693.3
If we subtract 2343 from 2970, we get 627.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6270, and continue the process.

Advancing to step 10:
The number 781 fits into 6270 8 times, leaving a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 38693.38
Subtract 6248 from 6270 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 11:
If we divide 220 by 781, we get 0 and a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 38693.38
Subtracting 0 from 220 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 12:
781 can be fit into 2200 2 times, resulting in a remainder of 638.
Use 2 as the next digit of our solution. 
Result so far: 38693.3802
Deduct 1562 from 2200 and we're left with 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Step 13:
781 can be fit into 6380 8 times, resulting in a remainder of 132.
Record the quotient 8 as the next digit in the result. 
Result so far: 38693.38028
Deduct 6248 from 6380 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 14:
If we divide 1320 by 781, we get 1 and a remainder of 539.
Use 1 as the next digit of our solution. 
Result so far: 38693.380281
If we take 781 away from 1320, we end up with 539.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5390, and continue the process.

Going ahead to step 15:
When dividing 5390 by 781, we get 6 with a remainder of 704.
The number 6 becomes the next digit in our result. 
Result so far: 38693.3802816
Deduct 4686 from 5390 and we're left with 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

On to step 16:
7040 divided by 781 is 9 with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 38693.38028169
If we subtract 7029 from 7040, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The quotient of the division is 38693.38028169, and the remainder is 1.1e-08.
