Let's divide 78909345 by 724
The aim is to understand the frequency of 724 in 78909345.

Step 1:
When dividing 7 by 724, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 724

Moving on to step 2:
When dividing 78 by 724, we get 0 with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Grab the next digit (9) from the dividend, add it to 78, then carry on: 789 / 724

Going ahead to step 3:
The number 724 fits into 789 1 times, leaving a remainder of 65.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 65 after subtracting 724 from 789.
Take the next digit (0) from the dividend and append it to 65, then repeat: 650 / 724

On to step 4:
724 can be fit into 650 0 times, resulting in a remainder of 650.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 650 leaves us with 650.
Include the next digit (9) from the dividend after 650, then repeat: 6509 / 724

Advancing to step 5:
724 can be fit into 6509 8 times, resulting in a remainder of 717.
The number 8 becomes the next digit in our result. 
Result so far: 108.0
If we subtract 5792 from 6509, we get 717.
Take the next digit (3) from the dividend and append it to 717, then repeat: 7173 / 724

Step 6:
724 can be fit into 7173 9 times, resulting in a remainder of 657.
Put 9 as the next digit of the answer. 
Result so far: 1089.0
If we subtract 6516 from 7173, we get 657.
Fetch the next digit (4) from the dividend, attach it to 657 and continue: 6574 / 724

Let's proceed to step 7:
When dividing 6574 by 724, we get 9 with a remainder of 58.
Use 9 as the next digit of our solution. 
Result so far: 10899.0
Deduct 6516 from 6574 and we're left with 58.
Grab the next digit (5) from the dividend, add it to 58, then carry on: 585 / 724

Let's proceed to step 8:
The number 724 fits into 585 0 times, leaving a remainder of 585.
The number 0 becomes the next digit in our result. 
Result so far: 108990.0
Subtracting 0 from 585 leaves us with 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Step 9:
724 goes into 5850 8 times with a remainder of 58.
The number 8 becomes the next digit in our result. 
Result so far: 108990.8
Subtract 5792 from 5850 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 10:
724 can be fit into 580 0 times, resulting in a remainder of 580.
Use 0 as the next digit of our solution. 
Result so far: 108990.8
If we subtract 0 from 580, we get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Moving on to step 11:
If we divide 5800 by 724, we get 8 and a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 108990.808
If we take 5792 away from 5800, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
724 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 108990.808
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 13:
When dividing 800 by 724, we get 1 with a remainder of 76.
Use 1 as the next digit of our solution. 
Result so far: 108990.80801
Subtracting 724 from 800 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 14:
724 goes into 760 1 times with a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 108990.808011
If we take 724 away from 760, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Our division results in 108990.808011 with a remaining 3.6e-06.
