We look at the division of 68545923 by 760 
The aim is to understand the frequency of 760 in 68545923.

On to step 1:
If we divide 6 by 760, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 760

On to step 2:
When dividing 68 by 760, we get 0 with a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Fetch the next digit (5) from the dividend, attach it to 68 and continue: 685 / 760

Going ahead to step 3:
The number 760 fits into 685 0 times, leaving a remainder of 685.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 685, we end up with 685.
Take the next digit (4) from the dividend and append it to 685, then repeat: 6854 / 760

Advancing to step 4:
The number 760 fits into 6854 9 times, leaving a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 14 after subtracting 6840 from 6854.
Grab the next digit (5) from the dividend, add it to 14, then carry on: 145 / 760

Step 5:
145 divided by 760 is 0 with a remainder of 145.
The number 0 becomes the next digit in our result. 
Result so far: 90.0
If we subtract 0 from 145, we get 145.
Bring next digit (9) of the dividend behind the 145 and repeat the process: 1459 / 760

On to step 6:
If we divide 1459 by 760, we get 1 and a remainder of 699.
Use 1 as the next digit of our solution. 
Result so far: 901.0
Deduct 760 from 1459 and we're left with 699.
Take the next digit (2) from the dividend and append it to 699, then repeat: 6992 / 760

On to step 7:
6992 divided by 760 is 9 with a remainder of 152.
The next digit of our result is 9. 
Result so far: 9019.0
Subtracting 6840 from 6992 leaves us with 152.
Fetch the next digit (3) from the dividend, attach it to 152 and continue: 1523 / 760

Moving on to step 8:
760 goes into 1523 2 times with a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 90192.0
If we subtract 1520 from 1523, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 9:
When dividing 30 by 760, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 90192.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
When dividing 300 by 760, we get 0 with a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 90192.0
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

After the division, we end up with 90192.0 and a remainder of 0.3.
