We divide 78503 by 65
The aim is to understand the frequency of 65 in 78503.

Moving on to step 1:
If we divide 7 by 65, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 65

Moving on to step 2:
When dividing 78 by 65, we get 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 65 away from 78, we end up with 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 65

Step 3:
When dividing 135 by 65, we get 2 with a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 130 from 135 to get 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 65

Advancing to step 4:
If we divide 50 by 65, we get 0 and a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 120.0
If we subtract 0 from 50, we get 50.
Take the next digit (3) from the dividend and append it to 50, then repeat: 503 / 65

Advancing to step 5:
503 divided by 65 is 7 with a remainder of 48.
Put 7 as the next digit of the answer. 
Result so far: 1207.0
If we subtract 455 from 503, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 6:
The number 65 fits into 480 7 times, leaving a remainder of 25.
The number 7 becomes the next digit in our result. 
Result so far: 1207.7
Subtract 455 from 480 to 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.

Step 7:
65 goes into 250 3 times with a remainder of 55.
Record the quotient 3 as the next digit in the result. 
Result so far: 1207.73
Subtracting 195 from 250 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 8:
If we divide 550 by 65, we get 8 and a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 1207.738
Deduct 520 from 550 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.

Let's proceed to step 9:
If we divide 300 by 65, we get 4 and a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 1207.7384
If we subtract 260 from 300, 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.

Going ahead to step 10:
When dividing 400 by 65, we get 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 1207.73846
Subtracting 390 from 400 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 11:
65 can be fit into 100 1 times, resulting in a remainder of 35.
Record the quotient 1 as the next digit in the result. 
Result so far: 1207.738461
Subtracting 65 from 100 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 12:
65 goes into 350 5 times with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 1207.7384615
Deduct 325 from 350 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 13:
250 divided by 65 is 3 with a remainder of 55.
Write down 3 as next digit of the result. 
Result so far: 1207.73846153
If we subtract 195 from 250, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The final result is 1207.73846153 with a remainder of 5.5e-08.
