69899014 divided by 690 
The aim is to understand the frequency of 690 in 69899014.

Moving on to step 1:
The number 690 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 690

On to step 2:
690 can be fit into 69 0 times, resulting in a remainder of 69.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Append the next digit (8) from the dividend to 69 and continue with: 698 / 690

Moving on to step 3:
If we divide 698 by 690, we get 1 and a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 690 from 698 to get 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 690

Step 4:
When dividing 89 by 690, we get 0 with a remainder of 89.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 89 after subtracting 0 from 89.
Take the next digit (9) from the dividend and append it to 89, then repeat: 899 / 690

Moving on to step 5:
690 can be fit into 899 1 times, resulting in a remainder of 209.
Use 1 as the next digit of our solution. 
Result so far: 101.0
If we subtract 690 from 899, we get 209.
Fetch the next digit (0) from the dividend, attach it to 209 and continue: 2090 / 690

Going ahead to step 6:
The number 690 fits into 2090 3 times, leaving a remainder of 20.
Put 3 as the next digit of the answer. 
Result so far: 1013.0
Subtract 2070 from 2090 to get 20.
Include the next digit (1) from the dividend after 20, then repeat: 201 / 690

Going ahead to step 7:
If we divide 201 by 690, we get 0 and a remainder of 201.
The next digit of our result is 0. 
Result so far: 10130.0
If we subtract 0 from 201, we get 201.
Take the next digit (4) from the dividend and append it to 201, then repeat: 2014 / 690

Moving on to step 8:
When dividing 2014 by 690, we get 2 with a remainder of 634.
Record the quotient 2 as the next digit in the result. 
Result so far: 101302.0
Subtract 1380 from 2014 to get 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

On to step 9:
690 goes into 6340 9 times with a remainder of 130.
Write down 9 as next digit of the result. 
Result so far: 101302.9
Subtracting 6210 from 6340 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 10:
690 can be fit into 1300 1 times, resulting in a remainder of 610.
Write down 1 as next digit of the result. 
Result so far: 101302.91
Subtracting 690 from 1300 leaves us with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Moving on to step 11:
6100 divided by 690 is 8 with a remainder of 580.
The next digit of our result is 8. 
Result so far: 101302.918
The remainder is 580 after subtracting 5520 from 6100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

On to step 12:
If we divide 5800 by 690, we get 8 and a remainder of 280.
The number 8 becomes the next digit in our result. 
Result so far: 101302.9188
If we subtract 5520 from 5800, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

The final outcome is 101302.9188, with a leftover of 0.0028.
