We divide 781841 by 65
The aim is to understand the frequency of 65 in 781841.

Advancing to step 1:
The number 65 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 65

Advancing to step 2:
65 can be fit into 78 1 times, resulting in a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 65 away from 78, we end up with 13.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 65

Moving on to step 3:
If we divide 131 by 65, we get 2 and a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 130 from 131 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 65

On to step 4:
When dividing 18 by 65, we get 0 with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 120.0
If we subtract 0 from 18, we get 18.
Append the next digit (4) from the dividend to 18 and continue with: 184 / 65

On to step 5:
65 goes into 184 2 times with a remainder of 54.
Write down 2 as next digit of the result. 
Result so far: 1202.0
Deduct 130 from 184 and we're left with 54.
Grab the next digit (1) from the dividend, add it to 54, then carry on: 541 / 65

Going ahead to step 6:
If we divide 541 by 65, we get 8 and a remainder of 21.
Record the quotient 8 as the next digit in the result. 
Result so far: 12028.0
If we take 520 away from 541, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
65 can be fit into 210 3 times, resulting in a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 12028.3
Subtracting 195 from 210 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.

Advancing to step 8:
When dividing 150 by 65, we get 2 with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 12028.32
Subtract 130 from 150 to get 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 9:
When dividing 200 by 65, we get 3 with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 12028.323
Subtracting 195 from 200 leaves us 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.

Moving on to step 10:
50 divided by 65 is 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 12028.323
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 11:
500 divided by 65 is 7 with a remainder of 45.
Put 7 as the next digit of the answer. 
Result so far: 12028.32307
Subtracting 455 from 500 leaves us 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 12:
65 goes into 450 6 times with a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 12028.323076
The remainder is 60 after subtracting 390 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 13:
600 divided by 65 is 9 with a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 12028.3230769
If we subtract 585 from 600, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 14:
150 divided by 65 is 2 with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 12028.32307692
Subtract 130 from 150 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 12028.32307692 with a remaining 2e-08.
