Let's divide 68945319 by 690
The aim is to understand the frequency of 690 in 68945319.

Let's proceed to step 1:
690 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 690

On to step 2:
690 goes into 68 0 times with a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Take the next digit (9) from the dividend and append it to 68, then repeat: 689 / 690

Let's proceed to step 3:
689 divided by 690 is 0 with a remainder of 689.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 689 after subtracting 0 from 689.
Append the next digit (4) from the dividend to 689 and continue with: 6894 / 690

Let's proceed to step 4:
690 can be fit into 6894 9 times, resulting in a remainder of 684.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 6210 away from 6894, we end up with 684.
Include the next digit (5) from the dividend after 684, then repeat: 6845 / 690

Moving on to step 5:
The number 690 fits into 6845 9 times, leaving a remainder of 635.
The next digit of our result is 9. 
Result so far: 99.0
If we take 6210 away from 6845, we end up with 635.
Bring next digit (3) of the dividend behind the 635 and repeat the process: 6353 / 690

Let's proceed to step 6:
When dividing 6353 by 690, we get 9 with a remainder of 143.
Put 9 as the next digit of the answer. 
Result so far: 999.0
Subtracting 6210 from 6353 leaves us with 143.
Fetch the next digit (1) from the dividend, attach it to 143 and continue: 1431 / 690

Step 7:
When dividing 1431 by 690, we get 2 with a remainder of 51.
The next digit of our result is 2. 
Result so far: 9992.0
The remainder is 51 after subtracting 1380 from 1431.
Append the next digit (9) from the dividend to 51 and continue with: 519 / 690

Moving on to step 8:
If we divide 519 by 690, we get 0 and a remainder of 519.
The number 0 becomes the next digit in our result. 
Result so far: 99920.0
Subtracting 0 from 519 leaves us with 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

Moving on to step 9:
690 goes into 5190 7 times with a remainder of 360.
Use 7 as the next digit of our solution. 
Result so far: 99920.7
Subtract 4830 from 5190 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 10:
690 can be fit into 3600 5 times, resulting in a remainder of 150.
The number 5 becomes the next digit in our result. 
Result so far: 99920.75
Subtracting 3450 from 3600 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 11:
When dividing 1500 by 690, we get 2 with a remainder of 120.
The next digit of our result is 2. 
Result so far: 99920.752
If we subtract 1380 from 1500, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 12:
690 goes into 1200 1 times with a remainder of 510.
The number 1 becomes the next digit in our result. 
Result so far: 99920.7521
Subtracting 690 from 1200 leaves us with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Let's proceed to step 13:
When dividing 5100 by 690, we get 7 with a remainder of 270.
The number 7 becomes the next digit in our result. 
Result so far: 99920.75217
Deduct 4830 from 5100 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Going ahead to step 14:
The number 690 fits into 2700 3 times, leaving a remainder of 630.
The number 3 becomes the next digit in our result. 
Result so far: 99920.752173
Subtract 2070 from 2700 to get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Moving on to step 15:
When dividing 6300 by 690, we get 9 with a remainder of 90.
Use 9 as the next digit of our solution. 
Result so far: 99920.7521739
If we take 6210 away from 6300, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 16:
690 goes into 900 1 times with a remainder of 210.
Write down 1 as next digit of the result. 
Result so far: 99920.75217391
If we subtract 690 from 900, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

After the division, we end up with 99920.75217391 and a remainder of 2.1e-07.
