27429854 ÷ 649 
The aim is to understand the frequency of 649 in 27429854.

Step 1:
If we divide 2 by 649, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 649

Step 2:
649 can be fit into 27 0 times, resulting in a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 27 leaves us with 27.
Grab the next digit (4) from the dividend, add it to 27, then carry on: 274 / 649

Let's proceed to step 3:
649 goes into 274 0 times with a remainder of 274.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 274, we get 274.
Grab the next digit (2) from the dividend, add it to 274, then carry on: 2742 / 649

Let's proceed to step 4:
If we divide 2742 by 649, we get 4 and a remainder of 146.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 2596 from 2742, we get 146.
Bring next digit (9) of the dividend behind the 146 and repeat the process: 1469 / 649

Moving on to step 5:
The number 649 fits into 1469 2 times, leaving a remainder of 171.
The next digit of our result is 2. 
Result so far: 42.0
Subtracting 1298 from 1469 leaves us with 171.
Include the next digit (8) from the dividend after 171, then repeat: 1718 / 649

Let's proceed to step 6:
When dividing 1718 by 649, we get 2 with a remainder of 420.
Write down 2 as next digit of the result. 
Result so far: 422.0
If we take 1298 away from 1718, we end up with 420.
Take the next digit (5) from the dividend and append it to 420, then repeat: 4205 / 649

Let's proceed to step 7:
4205 divided by 649 is 6 with a remainder of 311.
Use 6 as the next digit of our solution. 
Result so far: 4226.0
If we subtract 3894 from 4205, we get 311.
Bring next digit (4) of the dividend behind the 311 and repeat the process: 3114 / 649

Step 8:
The number 649 fits into 3114 4 times, leaving a remainder of 518.
Put 4 as the next digit of the answer. 
Result so far: 42264.0
Deduct 2596 from 3114 and we're left with 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Advancing to step 9:
The number 649 fits into 5180 7 times, leaving a remainder of 637.
Use 7 as the next digit of our solution. 
Result so far: 42264.7
The remainder is 637 after subtracting 4543 from 5180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6370, and continue the process.

Advancing to step 10:
The number 649 fits into 6370 9 times, leaving a remainder of 529.
Put 9 as the next digit of the answer. 
Result so far: 42264.79
If we take 5841 away from 6370, we end up with 529.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5290, and continue the process.

Let's proceed to step 11:
649 goes into 5290 8 times with a remainder of 98.
Use 8 as the next digit of our solution. 
Result so far: 42264.798
The remainder is 98 after subtracting 5192 from 5290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Advancing to step 12:
When dividing 980 by 649, we get 1 with a remainder of 331.
Put 1 as the next digit of the answer. 
Result so far: 42264.7981
If we take 649 away from 980, we end up with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Moving on to step 13:
If we divide 3310 by 649, we get 5 and a remainder of 65.
The next digit of our result is 5. 
Result so far: 42264.79815
Subtract 3245 from 3310 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 14:
When dividing 650 by 649, we get 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 42264.798151
If we take 649 away from 650, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 15:
649 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 42264.798151
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 16:
649 goes into 100 0 times with a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 42264.798151
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

After the division, we end up with 42264.798151 and a remainder of 1e-07.
