31366910 divided by 649 
The aim is to understand the frequency of 649 in 31366910.

On to step 1:
The number 649 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 649

Advancing to step 2:
When dividing 31 by 649, we get 0 with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Bring next digit (3) of the dividend behind the 31 and repeat the process: 313 / 649

Step 3:
If we divide 313 by 649, we get 0 and a remainder of 313.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 313, we get 313.
Fetch the next digit (6) from the dividend, attach it to 313 and continue: 3136 / 649

Let's proceed to step 4:
When dividing 3136 by 649, we get 4 with a remainder of 540.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 540 after subtracting 2596 from 3136.
Append the next digit (6) from the dividend to 540 and continue with: 5406 / 649

Advancing to step 5:
If we divide 5406 by 649, we get 8 and a remainder of 214.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
Subtracting 5192 from 5406 leaves us with 214.
Bring next digit (9) of the dividend behind the 214 and repeat the process: 2149 / 649

Going ahead to step 6:
2149 divided by 649 is 3 with a remainder of 202.
Put 3 as the next digit of the answer. 
Result so far: 483.0
If we take 1947 away from 2149, we end up with 202.
Include the next digit (1) from the dividend after 202, then repeat: 2021 / 649

On to step 7:
If we divide 2021 by 649, we get 3 and a remainder of 74.
The next digit of our result is 3. 
Result so far: 4833.0
Subtracting 1947 from 2021 leaves us with 74.
Append the next digit (0) from the dividend to 74 and continue with: 740 / 649

On to step 8:
649 goes into 740 1 times with a remainder of 91.
Use 1 as the next digit of our solution. 
Result so far: 48331.0
Subtracting 649 from 740 leaves us with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Moving on to step 9:
649 goes into 910 1 times with a remainder of 261.
Write down 1 as next digit of the result. 
Result so far: 48331.1
Deduct 649 from 910 and we're left with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

On to step 10:
When dividing 2610 by 649, we get 4 with a remainder of 14.
The next digit of our result is 4. 
Result so far: 48331.14
Deduct 2596 from 2610 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 11:
The number 649 fits into 140 0 times, leaving a remainder of 140.
The next digit of our result is 0. 
Result so far: 48331.14
If we subtract 0 from 140, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 12:
649 can be fit into 1400 2 times, resulting in a remainder of 102.
The next digit of our result is 2. 
Result so far: 48331.1402
If we take 1298 away from 1400, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Step 13:
When dividing 1020 by 649, we get 1 with a remainder of 371.
The next digit of our result is 1. 
Result so far: 48331.14021
Deduct 649 from 1020 and we're left with 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Moving on to step 14:
649 can be fit into 3710 5 times, resulting in a remainder of 465.
The number 5 becomes the next digit in our result. 
Result so far: 48331.140215
Subtracting 3245 from 3710 leaves us with 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Let's proceed to step 15:
When dividing 4650 by 649, we get 7 with a remainder of 107.
Record the quotient 7 as the next digit in the result. 
Result so far: 48331.1402157
The remainder is 107 after subtracting 4543 from 4650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Advancing to step 16:
If we divide 1070 by 649, we get 1 and a remainder of 421.
Write down 1 as next digit of the result. 
Result so far: 48331.14021571
Deduct 649 from 1070 and we're left with 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

The final outcome is 48331.14021571, with a leftover of 4.21e-07.
