We divide 30939916 by 689
The aim is to understand the frequency of 689 in 30939916.

Step 1:
3 divided by 689 is 0 with 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.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 689

On to step 2:
30 divided by 689 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Include the next digit (9) from the dividend after 30, then repeat: 309 / 689

Advancing to step 3:
When dividing 309 by 689, we get 0 with a remainder of 309.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 309, we end up with 309.
Grab the next digit (3) from the dividend, add it to 309, then carry on: 3093 / 689

Going ahead to step 4:
The number 689 fits into 3093 4 times, leaving a remainder of 337.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 2756 from 3093 leaves us with 337.
Append the next digit (9) from the dividend to 337 and continue with: 3379 / 689

Step 5:
689 can be fit into 3379 4 times, resulting in a remainder of 623.
Use 4 as the next digit of our solution. 
Result so far: 44.0
If we take 2756 away from 3379, we end up with 623.
Append the next digit (9) from the dividend to 623 and continue with: 6239 / 689

Let's proceed to step 6:
689 goes into 6239 9 times with a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 449.0
Subtracting 6201 from 6239 leaves us with 38.
Bring next digit (1) of the dividend behind the 38 and repeat the process: 381 / 689

Advancing to step 7:
The number 689 fits into 381 0 times, leaving a remainder of 381.
The next digit of our result is 0. 
Result so far: 4490.0
If we take 0 away from 381, we end up with 381.
Fetch the next digit (6) from the dividend, attach it to 381 and continue: 3816 / 689

Moving on to step 8:
689 can be fit into 3816 5 times, resulting in a remainder of 371.
The next digit of our result is 5. 
Result so far: 44905.0
Deduct 3445 from 3816 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 9:
3710 divided by 689 is 5 with a remainder of 265.
The next digit of our result is 5. 
Result so far: 44905.5
Subtracting 3445 from 3710 leaves us with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Step 10:
When dividing 2650 by 689, we get 3 with a remainder of 583.
The next digit of our result is 3. 
Result so far: 44905.53
Subtract 2067 from 2650 to get 583.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5830, and continue the process.

Step 11:
The number 689 fits into 5830 8 times, leaving a remainder of 318.
The number 8 becomes the next digit in our result. 
Result so far: 44905.538
The remainder is 318 after subtracting 5512 from 5830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Advancing to step 12:
If we divide 3180 by 689, we get 4 and a remainder of 424.
The next digit of our result is 4. 
Result so far: 44905.5384
The remainder is 424 after subtracting 2756 from 3180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Step 13:
When dividing 4240 by 689, we get 6 with a remainder of 106.
The next digit of our result is 6. 
Result so far: 44905.53846
Deduct 4134 from 4240 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 14:
1060 divided by 689 is 1 with a remainder of 371.
Use 1 as the next digit of our solution. 
Result so far: 44905.538461
If we take 689 away from 1060, we end up 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.

Let's proceed to step 15:
When dividing 3710 by 689, we get 5 with a remainder of 265.
The number 5 becomes the next digit in our result. 
Result so far: 44905.5384615
Subtracting 3445 from 3710 leaves us with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Step 16:
689 goes into 2650 3 times with a remainder of 583.
Record the quotient 3 as the next digit in the result. 
Result so far: 44905.53846153
The remainder is 583 after subtracting 2067 from 2650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5830, and continue the process.

The final outcome is 44905.53846153, with a leftover of 5.83e-07.
