We're dividing 398070 by 65 
The aim is to understand the frequency of 65 in 398070.

Advancing to step 1:
65 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 65

Going ahead to step 2:
39 divided by 65 is 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Include the next digit (8) from the dividend after 39, then repeat: 398 / 65

Moving on to step 3:
398 divided by 65 is 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 390 from 398 and we're left with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 65

On to step 4:
65 can be fit into 80 1 times, resulting in a remainder of 15.
The next digit of our result is 1. 
Result so far: 61.0
Subtract 65 from 80 to get 15.
Grab the next digit (7) from the dividend, add it to 15, then carry on: 157 / 65

Advancing to step 5:
157 divided by 65 is 2 with a remainder of 27.
Put 2 as the next digit of the answer. 
Result so far: 612.0
The remainder is 27 after subtracting 130 from 157.
Include the next digit (0) from the dividend after 27, then repeat: 270 / 65

Moving on to step 6:
65 can be fit into 270 4 times, resulting in a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 6124.0
If we take 260 away from 270, we end up 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 7:
100 divided by 65 is 1 with a remainder of 35.
Record the quotient 1 as the next digit in the result. 
Result so far: 6124.1
If we subtract 65 from 100, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 8:
65 can be fit into 350 5 times, resulting in a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 6124.15
If we subtract 325 from 350, we 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.

On to step 9:
The number 65 fits into 250 3 times, leaving a remainder of 55.
Write down 3 as next digit of the result. 
Result so far: 6124.153
Subtract 195 from 250 to 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.

On to step 10:
When dividing 550 by 65, we get 8 with a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 6124.1538
Subtracting 520 from 550 leaves us 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 11:
300 divided by 65 is 4 with a remainder of 40.
The next digit of our result is 4. 
Result so far: 6124.15384
Subtracting 260 from 300 leaves us with 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 12:
400 divided by 65 is 6 with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 6124.153846
If we take 390 away from 400, we end up 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.

Advancing to step 13:
The number 65 fits into 100 1 times, leaving a remainder of 35.
The next digit of our result is 1. 
Result so far: 6124.1538461
The remainder is 35 after subtracting 65 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 14:
65 can be fit into 350 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 6124.15384615
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.

The quotient of the division is 6124.15384615, and the remainder is 2.5e-08.
