We're dividing 1459519 by 665 
The aim is to understand the frequency of 665 in 1459519.

On to step 1:
665 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 665

On to step 2:
665 goes into 14 0 times with a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Bring next digit (5) of the dividend behind the 14 and repeat the process: 145 / 665

Advancing to step 3:
145 divided by 665 is 0 with a remainder of 145.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 145 after subtracting 0 from 145.
Append the next digit (9) from the dividend to 145 and continue with: 1459 / 665

On to step 4:
If we divide 1459 by 665, we get 2 and a remainder of 129.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 129 after subtracting 1330 from 1459.
Bring next digit (5) of the dividend behind the 129 and repeat the process: 1295 / 665

Advancing to step 5:
665 goes into 1295 1 times with a remainder of 630.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Deduct 665 from 1295 and we're left with 630.
Include the next digit (1) from the dividend after 630, then repeat: 6301 / 665

On to step 6:
When dividing 6301 by 665, we get 9 with a remainder of 316.
Record the quotient 9 as the next digit in the result. 
Result so far: 219.0
If we subtract 5985 from 6301, we get 316.
Grab the next digit (9) from the dividend, add it to 316, then carry on: 3169 / 665

Step 7:
3169 divided by 665 is 4 with a remainder of 509.
The number 4 becomes the next digit in our result. 
Result so far: 2194.0
If we take 2660 away from 3169, we end up with 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

Step 8:
665 can be fit into 5090 7 times, resulting in a remainder of 435.
Record the quotient 7 as the next digit in the result. 
Result so far: 2194.7
Deduct 4655 from 5090 and we're left with 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Going ahead to step 9:
665 can be fit into 4350 6 times, resulting in a remainder of 360.
Use 6 as the next digit of our solution. 
Result so far: 2194.76
If we take 3990 away from 4350, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 10:
The number 665 fits into 3600 5 times, leaving a remainder of 275.
Use 5 as the next digit of our solution. 
Result so far: 2194.765
If we take 3325 away from 3600, we end up with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Moving on to step 11:
The number 665 fits into 2750 4 times, leaving a remainder of 90.
Put 4 as the next digit of the answer. 
Result so far: 2194.7654
If we subtract 2660 from 2750, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 12:
665 goes into 900 1 times with a remainder of 235.
The number 1 becomes the next digit in our result. 
Result so far: 2194.76541
The remainder is 235 after subtracting 665 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Let's proceed to step 13:
If we divide 2350 by 665, we get 3 and a remainder of 355.
Put 3 as the next digit of the answer. 
Result so far: 2194.765413
Subtract 1995 from 2350 to get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Step 14:
3550 divided by 665 is 5 with a remainder of 225.
Write down 5 as next digit of the result. 
Result so far: 2194.7654135
Subtracting 3325 from 3550 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Going ahead to step 15:
If we divide 2250 by 665, we get 3 and a remainder of 255.
Use 3 as the next digit of our solution. 
Result so far: 2194.76541353
If we subtract 1995 from 2250, we get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

The quotient of the division is 2194.76541353, and the remainder is 2.55e-07.
