We look at the division of 78810416 by 727 
The aim is to understand the frequency of 727 in 78810416.

Step 1:
727 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 727

Step 2:
727 can be fit into 78 0 times, resulting in a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Append the next digit (8) from the dividend to 78 and continue with: 788 / 727

Let's proceed to step 3:
When dividing 788 by 727, we get 1 with a remainder of 61.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 727 from 788, we get 61.
Grab the next digit (1) from the dividend, add it to 61, then carry on: 611 / 727

Going ahead to step 4:
If we divide 611 by 727, we get 0 and a remainder of 611.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 611 after subtracting 0 from 611.
Fetch the next digit (0) from the dividend, attach it to 611 and continue: 6110 / 727

Moving on to step 5:
727 can be fit into 6110 8 times, resulting in a remainder of 294.
Write down 8 as next digit of the result. 
Result so far: 108.0
If we subtract 5816 from 6110, we get 294.
Take the next digit (4) from the dividend and append it to 294, then repeat: 2944 / 727

Moving on to step 6:
If we divide 2944 by 727, we get 4 and a remainder of 36.
The next digit of our result is 4. 
Result so far: 1084.0
The remainder is 36 after subtracting 2908 from 2944.
Bring next digit (1) of the dividend behind the 36 and repeat the process: 361 / 727

Advancing to step 7:
361 divided by 727 is 0 with a remainder of 361.
Use 0 as the next digit of our solution. 
Result so far: 10840.0
The remainder is 361 after subtracting 0 from 361.
Fetch the next digit (6) from the dividend, attach it to 361 and continue: 3616 / 727

Moving on to step 8:
The number 727 fits into 3616 4 times, leaving a remainder of 708.
Write down 4 as next digit of the result. 
Result so far: 108404.0
If we take 2908 away from 3616, we end up with 708.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

Let's proceed to step 9:
If we divide 7080 by 727, we get 9 and a remainder of 537.
Write down 9 as next digit of the result. 
Result so far: 108404.9
Deduct 6543 from 7080 and we're left with 537.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5370, and continue the process.

Moving on to step 10:
5370 divided by 727 is 7 with a remainder of 281.
Put 7 as the next digit of the answer. 
Result so far: 108404.97
The remainder is 281 after subtracting 5089 from 5370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

On to step 11:
727 can be fit into 2810 3 times, resulting in a remainder of 629.
Put 3 as the next digit of the answer. 
Result so far: 108404.973
If we subtract 2181 from 2810, we get 629.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6290, and continue the process.

Going ahead to step 12:
727 can be fit into 6290 8 times, resulting in a remainder of 474.
Record the quotient 8 as the next digit in the result. 
Result so far: 108404.9738
Deduct 5816 from 6290 and we're left with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

On to step 13:
4740 divided by 727 is 6 with a remainder of 378.
Put 6 as the next digit of the answer. 
Result so far: 108404.97386
The remainder is 378 after subtracting 4362 from 4740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

On to step 14:
3780 divided by 727 is 5 with a remainder of 145.
Record the quotient 5 as the next digit in the result. 
Result so far: 108404.973865
If we subtract 3635 from 3780, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Let's proceed to step 15:
1450 divided by 727 is 1 with a remainder of 723.
Use 1 as the next digit of our solution. 
Result so far: 108404.9738651
If we take 727 away from 1450, we end up with 723.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7230, and continue the process.

Moving on to step 16:
When dividing 7230 by 727, we get 9 with a remainder of 687.
Write down 9 as next digit of the result. 
Result so far: 108404.97386519
Subtracting 6543 from 7230 leaves us with 687.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6870, and continue the process.

The final outcome is 108404.97386519, with a leftover of 6.87e-07.
