We're dividing 30101289 by 649 
The aim is to understand the frequency of 649 in 30101289.

Step 1:
649 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 649

Step 2:
If we divide 30 by 649, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Take the next digit (1) from the dividend and append it to 30, then repeat: 301 / 649

On to step 3:
649 goes into 301 0 times with a remainder of 301.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 301 leaves us with 301.
Grab the next digit (0) from the dividend, add it to 301, then carry on: 3010 / 649

Advancing to step 4:
The number 649 fits into 3010 4 times, leaving a remainder of 414.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 2596 from 3010 leaves us with 414.
Append the next digit (1) from the dividend to 414 and continue with: 4141 / 649

Advancing to step 5:
If we divide 4141 by 649, we get 6 and a remainder of 247.
Put 6 as the next digit of the answer. 
Result so far: 46.0
If we take 3894 away from 4141, we end up with 247.
Append the next digit (2) from the dividend to 247 and continue with: 2472 / 649

Step 6:
2472 divided by 649 is 3 with a remainder of 525.
The next digit of our result is 3. 
Result so far: 463.0
Deduct 1947 from 2472 and we're left with 525.
Fetch the next digit (8) from the dividend, attach it to 525 and continue: 5258 / 649

On to step 7:
649 can be fit into 5258 8 times, resulting in a remainder of 66.
The next digit of our result is 8. 
Result so far: 4638.0
Subtracting 5192 from 5258 leaves us with 66.
Bring next digit (9) of the dividend behind the 66 and repeat the process: 669 / 649

Step 8:
649 goes into 669 1 times with a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 46381.0
The remainder is 20 after subtracting 649 from 669.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
The number 649 fits into 200 0 times, leaving a remainder of 200.
The next digit of our result is 0. 
Result so far: 46381.0
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 10:
2000 divided by 649 is 3 with a remainder of 53.
The next digit of our result is 3. 
Result so far: 46381.03
If we subtract 1947 from 2000, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 11:
649 can be fit into 530 0 times, resulting in a remainder of 530.
The next digit of our result is 0. 
Result so far: 46381.03
If we subtract 0 from 530, we get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Going ahead to step 12:
5300 divided by 649 is 8 with a remainder of 108.
Put 8 as the next digit of the answer. 
Result so far: 46381.0308
Subtracting 5192 from 5300 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Let's proceed to step 13:
The number 649 fits into 1080 1 times, leaving a remainder of 431.
The next digit of our result is 1. 
Result so far: 46381.03081
If we subtract 649 from 1080, we get 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

Step 14:
If we divide 4310 by 649, we get 6 and a remainder of 416.
Use 6 as the next digit of our solution. 
Result so far: 46381.030816
If we subtract 3894 from 4310, we get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Moving on to step 15:
649 goes into 4160 6 times with a remainder of 266.
Use 6 as the next digit of our solution. 
Result so far: 46381.0308166
Deduct 3894 from 4160 and we're left with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

The quotient of the division is 46381.0308166, and the remainder is 2.66e-06.
