We divide 71317691 by 719
The aim is to understand the frequency of 719 in 71317691.

Moving on to step 1:
If we divide 7 by 719, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 719

On to step 2:
The number 719 fits into 71 0 times, leaving a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Bring next digit (3) of the dividend behind the 71 and repeat the process: 713 / 719

Advancing to step 3:
719 can be fit into 713 0 times, resulting in a remainder of 713.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 713 after subtracting 0 from 713.
Include the next digit (1) from the dividend after 713, then repeat: 7131 / 719

On to step 4:
719 can be fit into 7131 9 times, resulting in a remainder of 660.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 6471 from 7131 leaves us with 660.
Fetch the next digit (7) from the dividend, attach it to 660 and continue: 6607 / 719

Advancing to step 5:
719 goes into 6607 9 times with a remainder of 136.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
The remainder is 136 after subtracting 6471 from 6607.
Include the next digit (6) from the dividend after 136, then repeat: 1366 / 719

Advancing to step 6:
719 goes into 1366 1 times with a remainder of 647.
The next digit of our result is 1. 
Result so far: 991.0
The remainder is 647 after subtracting 719 from 1366.
Bring next digit (9) of the dividend behind the 647 and repeat the process: 6479 / 719

On to step 7:
719 goes into 6479 9 times with a remainder of 8.
The next digit of our result is 9. 
Result so far: 9919.0
If we take 6471 away from 6479, we end up with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 719

Step 8:
When dividing 81 by 719, we get 0 with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 99190.0
Subtract 0 from 81 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 9:
719 can be fit into 810 1 times, resulting in a remainder of 91.
Record the quotient 1 as the next digit in the result. 
Result so far: 99190.1
Subtract 719 from 810 to get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Going ahead to step 10:
If we divide 910 by 719, we get 1 and a remainder of 191.
Use 1 as the next digit of our solution. 
Result so far: 99190.11
If we subtract 719 from 910, we get 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

The quotient of the division is 99190.11, and the remainder is 0.191.
