72238139 ÷ 768 
The aim is to understand the frequency of 768 in 72238139.

Step 1:
The number 768 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 768

Advancing to step 2:
768 goes into 72 0 times with a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Bring next digit (2) of the dividend behind the 72 and repeat the process: 722 / 768

Advancing to step 3:
The number 768 fits into 722 0 times, leaving a remainder of 722.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 722 and we're left with 722.
Include the next digit (3) from the dividend after 722, then repeat: 7223 / 768

Advancing to step 4:
768 can be fit into 7223 9 times, resulting in a remainder of 311.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 6912 from 7223 and we're left with 311.
Fetch the next digit (8) from the dividend, attach it to 311 and continue: 3118 / 768

Moving on to step 5:
768 can be fit into 3118 4 times, resulting in a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 94.0
Subtracting 3072 from 3118 leaves us with 46.
Grab the next digit (1) from the dividend, add it to 46, then carry on: 461 / 768

Let's proceed to step 6:
461 divided by 768 is 0 with a remainder of 461.
Record the quotient 0 as the next digit in the result. 
Result so far: 940.0
If we take 0 away from 461, we end up with 461.
Append the next digit (3) from the dividend to 461 and continue with: 4613 / 768

Step 7:
4613 divided by 768 is 6 with a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 9406.0
Subtracting 4608 from 4613 leaves us with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 768

On to step 8:
768 goes into 59 0 times with a remainder of 59.
Put 0 as the next digit of the answer. 
Result so far: 94060.0
If we subtract 0 from 59, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 9:
768 goes into 590 0 times with a remainder of 590.
Use 0 as the next digit of our solution. 
Result so far: 94060.0
If we subtract 0 from 590, we get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Step 10:
If we divide 5900 by 768, we get 7 and a remainder of 524.
The next digit of our result is 7. 
Result so far: 94060.07
If we subtract 5376 from 5900, we get 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Moving on to step 11:
768 can be fit into 5240 6 times, resulting in a remainder of 632.
Write down 6 as next digit of the result. 
Result so far: 94060.076
Subtracting 4608 from 5240 leaves us with 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Let's proceed to step 12:
The number 768 fits into 6320 8 times, leaving a remainder of 176.
Record the quotient 8 as the next digit in the result. 
Result so far: 94060.0768
The remainder is 176 after subtracting 6144 from 6320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 13:
768 can be fit into 1760 2 times, resulting in a remainder of 224.
Put 2 as the next digit of the answer. 
Result so far: 94060.07682
Deduct 1536 from 1760 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 14:
When dividing 2240 by 768, we get 2 with a remainder of 704.
The next digit of our result is 2. 
Result so far: 94060.076822
If we take 1536 away from 2240, we end up with 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

After the division, we end up with 94060.076822 and a remainder of 7.04e-05.
