Let's divide 30450378 by 719
The aim is to understand the frequency of 719 in 30450378.

Step 1:
3 divided by 719 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 719

Moving on to step 2:
719 goes into 30 0 times with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Bring next digit (4) of the dividend behind the 30 and repeat the process: 304 / 719

Advancing to step 3:
719 goes into 304 0 times with a remainder of 304.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 304, we end up with 304.
Include the next digit (5) from the dividend after 304, then repeat: 3045 / 719

Step 4:
3045 divided by 719 is 4 with a remainder of 169.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 2876 from 3045 and we're left with 169.
Fetch the next digit (0) from the dividend, attach it to 169 and continue: 1690 / 719

On to step 5:
719 goes into 1690 2 times with a remainder of 252.
Write down 2 as next digit of the result. 
Result so far: 42.0
If we take 1438 away from 1690, we end up with 252.
Bring next digit (3) of the dividend behind the 252 and repeat the process: 2523 / 719

Advancing to step 6:
719 goes into 2523 3 times with a remainder of 366.
Write down 3 as next digit of the result. 
Result so far: 423.0
If we take 2157 away from 2523, we end up with 366.
Take the next digit (7) from the dividend and append it to 366, then repeat: 3667 / 719

Let's proceed to step 7:
719 goes into 3667 5 times with a remainder of 72.
The number 5 becomes the next digit in our result. 
Result so far: 4235.0
The remainder is 72 after subtracting 3595 from 3667.
Take the next digit (8) from the dividend and append it to 72, then repeat: 728 / 719

Advancing to step 8:
The number 719 fits into 728 1 times, leaving a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 42351.0
Subtract 719 from 728 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 9:
719 can be fit into 90 0 times, resulting in a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 42351.0
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 10:
When dividing 900 by 719, we get 1 with a remainder of 181.
Record the quotient 1 as the next digit in the result. 
Result so far: 42351.01
Subtract 719 from 900 to get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Advancing to step 11:
The number 719 fits into 1810 2 times, leaving a remainder of 372.
Put 2 as the next digit of the answer. 
Result so far: 42351.012
If we take 1438 away from 1810, we end up with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

On to step 12:
If we divide 3720 by 719, we get 5 and a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 42351.0125
Subtracting 3595 from 3720 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 13:
The number 719 fits into 1250 1 times, leaving a remainder of 531.
Record the quotient 1 as the next digit in the result. 
Result so far: 42351.01251
If we subtract 719 from 1250, we get 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

Going ahead to step 14:
When dividing 5310 by 719, we get 7 with a remainder of 277.
The number 7 becomes the next digit in our result. 
Result so far: 42351.012517
Subtracting 5033 from 5310 leaves us with 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Advancing to step 15:
The number 719 fits into 2770 3 times, leaving a remainder of 613.
Write down 3 as next digit of the result. 
Result so far: 42351.0125173
Subtracting 2157 from 2770 leaves us with 613.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6130, and continue the process.

Moving on to step 16:
719 goes into 6130 8 times with a remainder of 378.
Record the quotient 8 as the next digit in the result. 
Result so far: 42351.01251738
Subtracting 5752 from 6130 leaves us with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

The final outcome is 42351.01251738, with a leftover of 3.78e-07.
