Let's divide 78163788 by 725
The aim is to understand the frequency of 725 in 78163788.

Let's proceed to step 1:
725 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 725

Let's proceed to step 2:
The number 725 fits into 78 0 times, leaving a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Include the next digit (1) from the dividend after 78, then repeat: 781 / 725

Going ahead to step 3:
725 goes into 781 1 times with a remainder of 56.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 56 after subtracting 725 from 781.
Take the next digit (6) from the dividend and append it to 56, then repeat: 566 / 725

Let's proceed to step 4:
725 goes into 566 0 times with a remainder of 566.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 566, we get 566.
Grab the next digit (3) from the dividend, add it to 566, then carry on: 5663 / 725

Let's proceed to step 5:
5663 divided by 725 is 7 with a remainder of 588.
Record the quotient 7 as the next digit in the result. 
Result so far: 107.0
If we subtract 5075 from 5663, we get 588.
Fetch the next digit (7) from the dividend, attach it to 588 and continue: 5887 / 725

Advancing to step 6:
725 goes into 5887 8 times with a remainder of 87.
The number 8 becomes the next digit in our result. 
Result so far: 1078.0
If we subtract 5800 from 5887, we get 87.
Append the next digit (8) from the dividend to 87 and continue with: 878 / 725

Going ahead to step 7:
725 goes into 878 1 times with a remainder of 153.
The next digit of our result is 1. 
Result so far: 10781.0
If we subtract 725 from 878, we get 153.
Append the next digit (8) from the dividend to 153 and continue with: 1538 / 725

Advancing to step 8:
725 can be fit into 1538 2 times, resulting in a remainder of 88.
Use 2 as the next digit of our solution. 
Result so far: 107812.0
Deduct 1450 from 1538 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 9:
725 can be fit into 880 1 times, resulting in a remainder of 155.
Record the quotient 1 as the next digit in the result. 
Result so far: 107812.1
Deduct 725 from 880 and we're left with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Going ahead to step 10:
If we divide 1550 by 725, we get 2 and a remainder of 100.
Use 2 as the next digit of our solution. 
Result so far: 107812.12
If we subtract 1450 from 1550, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 11:
1000 divided by 725 is 1 with a remainder of 275.
The number 1 becomes the next digit in our result. 
Result so far: 107812.121
Subtracting 725 from 1000 leaves us with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Let's proceed to step 12:
If we divide 2750 by 725, we get 3 and a remainder of 575.
The next digit of our result is 3. 
Result so far: 107812.1213
The remainder is 575 after subtracting 2175 from 2750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Step 13:
When dividing 5750 by 725, we get 7 with a remainder of 675.
Put 7 as the next digit of the answer. 
Result so far: 107812.12137
If we subtract 5075 from 5750, we get 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

Moving on to step 14:
If we divide 6750 by 725, we get 9 and a remainder of 225.
Use 9 as the next digit of our solution. 
Result so far: 107812.121379
Deduct 6525 from 6750 and we're left with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Advancing to step 15:
2250 divided by 725 is 3 with a remainder of 75.
Use 3 as the next digit of our solution. 
Result so far: 107812.1213793
If we subtract 2175 from 2250, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 16:
725 can be fit into 750 1 times, resulting in a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 107812.12137931
If we subtract 725 from 750, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final outcome is 107812.12137931, with a leftover of 2.5e-08.
