Let's divide 645977 by 65
The aim is to understand the frequency of 65 in 645977.

Step 1:
The number 65 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 65

On to step 2:
64 divided by 65 is 0 with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Bring next digit (5) of the dividend behind the 64 and repeat the process: 645 / 65

Going ahead to step 3:
If we divide 645 by 65, we get 9 and a remainder of 60.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 585 from 645 leaves us with 60.
Grab the next digit (9) from the dividend, add it to 60, then carry on: 609 / 65

On to step 4:
609 divided by 65 is 9 with a remainder of 24.
Write down 9 as next digit of the result. 
Result so far: 99.0
Subtracting 585 from 609 leaves us with 24.
Fetch the next digit (7) from the dividend, attach it to 24 and continue: 247 / 65

Going ahead to step 5:
247 divided by 65 is 3 with a remainder of 52.
The number 3 becomes the next digit in our result. 
Result so far: 993.0
Deduct 195 from 247 and we're left with 52.
Grab the next digit (7) from the dividend, add it to 52, then carry on: 527 / 65

Moving on to step 6:
527 divided by 65 is 8 with a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 9938.0
If we subtract 520 from 527, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
When dividing 70 by 65, we get 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 9938.1
Deduct 65 from 70 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
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: 9938.1
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
If we divide 500 by 65, we get 7 and a remainder of 45.
Write down 7 as next digit of the result. 
Result so far: 9938.107
If we take 455 away from 500, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 10:
When dividing 450 by 65, we get 6 with a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 9938.1076
If we take 390 away from 450, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 11:
If we divide 600 by 65, we get 9 and a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 9938.10769
Subtracting 585 from 600 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 12:
If we divide 150 by 65, we get 2 and a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 9938.107692
Subtracting 130 from 150 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
If we divide 200 by 65, we get 3 and a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 9938.1076923
If we subtract 195 from 200, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 14:
65 goes into 50 0 times with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 9938.1076923
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 9938.1076923 and a remainder of 5e-08.
