97139494 ÷ 649 
The aim is to understand the frequency of 649 in 97139494.

Advancing to step 1:
649 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 649

Advancing to step 2:
If we divide 97 by 649, we get 0 and a remainder of 97.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 97 leaves us with 97.
Include the next digit (1) from the dividend after 97, then repeat: 971 / 649

Step 3:
649 can be fit into 971 1 times, resulting in a remainder of 322.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 649 from 971, we get 322.
Take the next digit (3) from the dividend and append it to 322, then repeat: 3223 / 649

Step 4:
If we divide 3223 by 649, we get 4 and a remainder of 627.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we take 2596 away from 3223, we end up with 627.
Fetch the next digit (9) from the dividend, attach it to 627 and continue: 6279 / 649

Moving on to step 5:
When dividing 6279 by 649, we get 9 with a remainder of 438.
Use 9 as the next digit of our solution. 
Result so far: 149.0
Deduct 5841 from 6279 and we're left with 438.
Append the next digit (4) from the dividend to 438 and continue with: 4384 / 649

Moving on to step 6:
If we divide 4384 by 649, we get 6 and a remainder of 490.
The next digit of our result is 6. 
Result so far: 1496.0
If we take 3894 away from 4384, we end up with 490.
Include the next digit (9) from the dividend after 490, then repeat: 4909 / 649

Going ahead to step 7:
649 can be fit into 4909 7 times, resulting in a remainder of 366.
The number 7 becomes the next digit in our result. 
Result so far: 14967.0
Subtracting 4543 from 4909 leaves us with 366.
Append the next digit (4) from the dividend to 366 and continue with: 3664 / 649

Let's proceed to step 8:
When dividing 3664 by 649, we get 5 with a remainder of 419.
Record the quotient 5 as the next digit in the result. 
Result so far: 149675.0
If we take 3245 away from 3664, we end up with 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Step 9:
The number 649 fits into 4190 6 times, leaving a remainder of 296.
Use 6 as the next digit of our solution. 
Result so far: 149675.6
Subtract 3894 from 4190 to get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

On to step 10:
If we divide 2960 by 649, we get 4 and a remainder of 364.
Put 4 as the next digit of the answer. 
Result so far: 149675.64
Subtract 2596 from 2960 to get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Step 11:
When dividing 3640 by 649, we get 5 with a remainder of 395.
Put 5 as the next digit of the answer. 
Result so far: 149675.645
If we take 3245 away from 3640, we end up with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Moving on to step 12:
649 can be fit into 3950 6 times, resulting in a remainder of 56.
The number 6 becomes the next digit in our result. 
Result so far: 149675.6456
The remainder is 56 after subtracting 3894 from 3950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 13:
560 divided by 649 is 0 with a remainder of 560.
Write down 0 as next digit of the result. 
Result so far: 149675.6456
The remainder is 560 after subtracting 0 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Moving on to step 14:
If we divide 5600 by 649, we get 8 and a remainder of 408.
The number 8 becomes the next digit in our result. 
Result so far: 149675.645608
Subtracting 5192 from 5600 leaves us with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Step 15:
When dividing 4080 by 649, we get 6 with a remainder of 186.
Use 6 as the next digit of our solution. 
Result so far: 149675.6456086
If we take 3894 away from 4080, we end up with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 16:
When dividing 1860 by 649, we get 2 with a remainder of 562.
The next digit of our result is 2. 
Result so far: 149675.64560862
If we take 1298 away from 1860, we end up with 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

The final result is 149675.64560862 with a remainder of 5.62e-07.
