We look at the division of 76926123 by 690 
The aim is to understand the frequency of 690 in 76926123.

On to step 1:
7 divided by 690 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 690

Moving on to step 2:
The number 690 fits into 76 0 times, leaving a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 76 to get 76.
Take the next digit (9) from the dividend and append it to 76, then repeat: 769 / 690

On to step 3:
The number 690 fits into 769 1 times, leaving a remainder of 79.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 690 from 769, we get 79.
Bring next digit (2) of the dividend behind the 79 and repeat the process: 792 / 690

Advancing to step 4:
690 goes into 792 1 times with a remainder of 102.
Put 1 as the next digit of the answer. 
Result so far: 11.0
The remainder is 102 after subtracting 690 from 792.
Take the next digit (6) from the dividend and append it to 102, then repeat: 1026 / 690

On to step 5:
690 goes into 1026 1 times with a remainder of 336.
Put 1 as the next digit of the answer. 
Result so far: 111.0
If we take 690 away from 1026, we end up with 336.
Bring next digit (1) of the dividend behind the 336 and repeat the process: 3361 / 690

On to step 6:
The number 690 fits into 3361 4 times, leaving a remainder of 601.
Write down 4 as next digit of the result. 
Result so far: 1114.0
Subtracting 2760 from 3361 leaves us with 601.
Append the next digit (2) from the dividend to 601 and continue with: 6012 / 690

Going ahead to step 7:
If we divide 6012 by 690, we get 8 and a remainder of 492.
The next digit of our result is 8. 
Result so far: 11148.0
Subtract 5520 from 6012 to get 492.
Fetch the next digit (3) from the dividend, attach it to 492 and continue: 4923 / 690

On to step 8:
690 goes into 4923 7 times with a remainder of 93.
The next digit of our result is 7. 
Result so far: 111487.0
If we take 4830 away from 4923, we end up with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Moving on to step 9:
690 goes into 930 1 times with a remainder of 240.
Put 1 as the next digit of the answer. 
Result so far: 111487.1
The remainder is 240 after subtracting 690 from 930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 10:
The number 690 fits into 2400 3 times, leaving a remainder of 330.
The number 3 becomes the next digit in our result. 
Result so far: 111487.13
Subtract 2070 from 2400 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Step 11:
3300 divided by 690 is 4 with a remainder of 540.
The number 4 becomes the next digit in our result. 
Result so far: 111487.134
Subtract 2760 from 3300 to get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Moving on to step 12:
690 can be fit into 5400 7 times, resulting in a remainder of 570.
Record the quotient 7 as the next digit in the result. 
Result so far: 111487.1347
Deduct 4830 from 5400 and we're left with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Going ahead to step 13:
690 can be fit into 5700 8 times, resulting in a remainder of 180.
The next digit of our result is 8. 
Result so far: 111487.13478
If we subtract 5520 from 5700, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 14:
1800 divided by 690 is 2 with a remainder of 420.
Use 2 as the next digit of our solution. 
Result so far: 111487.134782
Subtracting 1380 from 1800 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 15:
4200 divided by 690 is 6 with a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 111487.1347826
The remainder is 60 after subtracting 4140 from 4200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 16:
690 goes into 600 0 times with a remainder of 600.
The next digit of our result is 0. 
Result so far: 111487.1347826
Subtract 0 from 600 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The quotient of the division is 111487.1347826, and the remainder is 6e-07.
