Let's divide 72648868 by 738
The aim is to understand the frequency of 738 in 72648868.

On to step 1:
738 can be fit into 7 0 times, resulting in 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.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 738

Going ahead to step 2:
72 divided by 738 is 0 with a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Bring next digit (6) of the dividend behind the 72 and repeat the process: 726 / 738

Going ahead to step 3:
The number 738 fits into 726 0 times, leaving a remainder of 726.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 726 after subtracting 0 from 726.
Grab the next digit (4) from the dividend, add it to 726, then carry on: 7264 / 738

Advancing to step 4:
738 can be fit into 7264 9 times, resulting in a remainder of 622.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 6642 from 7264 to get 622.
Bring next digit (8) of the dividend behind the 622 and repeat the process: 6228 / 738

Let's proceed to step 5:
6228 divided by 738 is 8 with a remainder of 324.
Write down 8 as next digit of the result. 
Result so far: 98.0
Deduct 5904 from 6228 and we're left with 324.
Take the next digit (8) from the dividend and append it to 324, then repeat: 3248 / 738

Advancing to step 6:
738 can be fit into 3248 4 times, resulting in a remainder of 296.
Record the quotient 4 as the next digit in the result. 
Result so far: 984.0
The remainder is 296 after subtracting 2952 from 3248.
Include the next digit (6) from the dividend after 296, then repeat: 2966 / 738

On to step 7:
738 can be fit into 2966 4 times, resulting in a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 9844.0
Subtract 2952 from 2966 to get 14.
Append the next digit (8) from the dividend to 14 and continue with: 148 / 738

Advancing to step 8:
When dividing 148 by 738, we get 0 with a remainder of 148.
Use 0 as the next digit of our solution. 
Result so far: 98440.0
If we take 0 away from 148, we end up with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 9:
If we divide 1480 by 738, we get 2 and a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 98440.2
If we take 1476 away from 1480, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
When dividing 40 by 738, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 98440.2
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
738 goes into 400 0 times with a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 98440.2
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final outcome is 98440.2, with a leftover of 0.04.
