90294935 ÷ 649 
The aim is to understand the frequency of 649 in 90294935.

Moving on to step 1:
If we divide 9 by 649, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 649

Going ahead to step 2:
The number 649 fits into 90 0 times, leaving a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Bring next digit (2) of the dividend behind the 90 and repeat the process: 902 / 649

On to step 3:
If we divide 902 by 649, we get 1 and a remainder of 253.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 253 after subtracting 649 from 902.
Grab the next digit (9) from the dividend, add it to 253, then carry on: 2539 / 649

Going ahead to step 4:
The number 649 fits into 2539 3 times, leaving a remainder of 592.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 1947 away from 2539, we end up with 592.
Take the next digit (4) from the dividend and append it to 592, then repeat: 5924 / 649

On to step 5:
When dividing 5924 by 649, we get 9 with a remainder of 83.
The number 9 becomes the next digit in our result. 
Result so far: 139.0
If we subtract 5841 from 5924, we get 83.
Grab the next digit (9) from the dividend, add it to 83, then carry on: 839 / 649

Moving on to step 6:
When dividing 839 by 649, we get 1 with a remainder of 190.
Put 1 as the next digit of the answer. 
Result so far: 1391.0
Subtracting 649 from 839 leaves us with 190.
Include the next digit (3) from the dividend after 190, then repeat: 1903 / 649

Advancing to step 7:
The number 649 fits into 1903 2 times, leaving a remainder of 605.
Write down 2 as next digit of the result. 
Result so far: 13912.0
The remainder is 605 after subtracting 1298 from 1903.
Fetch the next digit (5) from the dividend, attach it to 605 and continue: 6055 / 649

Let's proceed to step 8:
649 goes into 6055 9 times with a remainder of 214.
The number 9 becomes the next digit in our result. 
Result so far: 139129.0
Deduct 5841 from 6055 and we're left with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Moving on to step 9:
When dividing 2140 by 649, we get 3 with a remainder of 193.
Use 3 as the next digit of our solution. 
Result so far: 139129.3
Deduct 1947 from 2140 and we're left with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Advancing to step 10:
649 goes into 1930 2 times with a remainder of 632.
Use 2 as the next digit of our solution. 
Result so far: 139129.32
If we subtract 1298 from 1930, we get 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Advancing to step 11:
649 can be fit into 6320 9 times, resulting in a remainder of 479.
The number 9 becomes the next digit in our result. 
Result so far: 139129.329
Subtract 5841 from 6320 to get 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

Going ahead to step 12:
When dividing 4790 by 649, we get 7 with a remainder of 247.
The number 7 becomes the next digit in our result. 
Result so far: 139129.3297
If we take 4543 away from 4790, we end up with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Let's proceed to step 13:
649 can be fit into 2470 3 times, resulting in a remainder of 523.
Use 3 as the next digit of our solution. 
Result so far: 139129.32973
If we take 1947 away from 2470, we end up with 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

On to step 14:
If we divide 5230 by 649, we get 8 and a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 139129.329738
Subtract 5192 from 5230 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 15:
When dividing 380 by 649, we get 0 with a remainder of 380.
Use 0 as the next digit of our solution. 
Result so far: 139129.329738
If we subtract 0 from 380, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 16:
The number 649 fits into 3800 5 times, leaving a remainder of 555.
Put 5 as the next digit of the answer. 
Result so far: 139129.32973805
Subtracting 3245 from 3800 leaves us with 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

In conclusion, the division gives 139129.32973805 with a balance of 5.55e-07.
