Let's divide 620621 by 65
The aim is to understand the frequency of 65 in 620621.

Let's proceed to step 1:
65 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 65

On to step 2:
62 divided by 65 is 0 with a remainder of 62.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 62 after subtracting 0 from 62.
Grab the next digit (0) from the dividend, add it to 62, then carry on: 620 / 65

Advancing to step 3:
When dividing 620 by 65, we get 9 with a remainder of 35.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 585 from 620 and we're left with 35.
Append the next digit (6) from the dividend to 35 and continue with: 356 / 65

On to step 4:
356 divided by 65 is 5 with a remainder of 31.
Use 5 as the next digit of our solution. 
Result so far: 95.0
If we take 325 away from 356, we end up with 31.
Take the next digit (2) from the dividend and append it to 31, then repeat: 312 / 65

Moving on to step 5:
65 goes into 312 4 times with a remainder of 52.
The next digit of our result is 4. 
Result so far: 954.0
Subtracting 260 from 312 leaves us with 52.
Fetch the next digit (1) from the dividend, attach it to 52 and continue: 521 / 65

Advancing to step 6:
When dividing 521 by 65, we get 8 with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 9548.0
Deduct 520 from 521 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
If we divide 10 by 65, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 9548.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
If we divide 100 by 65, we get 1 and a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 9548.01
Subtract 65 from 100 to 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.

Step 9:
The number 65 fits into 350 5 times, leaving a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 9548.015
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.

Step 10:
If we divide 250 by 65, we get 3 and a remainder of 55.
Write down 3 as next digit of the result. 
Result so far: 9548.0153
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.

Step 11:
65 can be fit into 550 8 times, resulting in a remainder of 30.
The next digit of our result is 8. 
Result so far: 9548.01538
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.

Step 12:
The number 65 fits into 300 4 times, leaving a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 9548.015384
Deduct 260 from 300 and we're left 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.

Advancing to step 13:
65 can be fit into 400 6 times, resulting in a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 9548.0153846
The remainder is 10 after subtracting 390 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 14:
65 can be fit into 100 1 times, resulting in a remainder of 35.
The next digit of our result is 1. 
Result so far: 9548.01538461
Subtract 65 from 100 to 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.

The quotient of the division is 9548.01538461, and the remainder is 3.5e-08.
