We're dividing 8480874 by 649 
The aim is to understand the frequency of 649 in 8480874.

Let's proceed to step 1:
When dividing 8 by 649, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 649

Let's proceed to step 2:
When dividing 84 by 649, we get 0 with a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 84, we end up with 84.
Append the next digit (8) from the dividend to 84 and continue with: 848 / 649

Let's proceed to step 3:
649 can be fit into 848 1 times, resulting in a remainder of 199.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 649 from 848 to get 199.
Include the next digit (0) from the dividend after 199, then repeat: 1990 / 649

Let's proceed to step 4:
649 goes into 1990 3 times with a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 1947 from 1990, we get 43.
Fetch the next digit (8) from the dividend, attach it to 43 and continue: 438 / 649

Step 5:
438 divided by 649 is 0 with a remainder of 438.
Put 0 as the next digit of the answer. 
Result so far: 130.0
If we take 0 away from 438, we end up with 438.
Grab the next digit (7) from the dividend, add it to 438, then carry on: 4387 / 649

Moving on to step 6:
If we divide 4387 by 649, we get 6 and a remainder of 493.
Write down 6 as next digit of the result. 
Result so far: 1306.0
The remainder is 493 after subtracting 3894 from 4387.
Bring next digit (4) of the dividend behind the 493 and repeat the process: 4934 / 649

On to step 7:
649 can be fit into 4934 7 times, resulting in a remainder of 391.
The next digit of our result is 7. 
Result so far: 13067.0
Deduct 4543 from 4934 and we're left with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Going ahead to step 8:
649 can be fit into 3910 6 times, resulting in a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 13067.6
If we take 3894 away from 3910, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
When dividing 160 by 649, we get 0 with a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 13067.6
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 10:
649 goes into 1600 2 times with a remainder of 302.
Record the quotient 2 as the next digit in the result. 
Result so far: 13067.602
The remainder is 302 after subtracting 1298 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Going ahead to step 11:
When dividing 3020 by 649, we get 4 with a remainder of 424.
The number 4 becomes the next digit in our result. 
Result so far: 13067.6024
The remainder is 424 after subtracting 2596 from 3020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Going ahead to step 12:
If we divide 4240 by 649, we get 6 and a remainder of 346.
Write down 6 as next digit of the result. 
Result so far: 13067.60246
Subtract 3894 from 4240 to get 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Step 13:
649 can be fit into 3460 5 times, resulting in a remainder of 215.
The number 5 becomes the next digit in our result. 
Result so far: 13067.602465
Subtracting 3245 from 3460 leaves us with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Step 14:
If we divide 2150 by 649, we get 3 and a remainder of 203.
Record the quotient 3 as the next digit in the result. 
Result so far: 13067.6024653
The remainder is 203 after subtracting 1947 from 2150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Step 15:
If we divide 2030 by 649, we get 3 and a remainder of 83.
Write down 3 as next digit of the result. 
Result so far: 13067.60246533
Subtract 1947 from 2030 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Our division results in 13067.60246533 with a remaining 8.3e-08.
