We look at the division of 76050847 by 690 
The aim is to understand the frequency of 690 in 76050847.

Going ahead to step 1:
If we divide 7 by 690, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 690

Let's proceed to step 2:
690 can be fit into 76 0 times, resulting in a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 76 after subtracting 0 from 76.
Include the next digit (0) from the dividend after 76, then repeat: 760 / 690

Let's proceed to step 3:
760 divided by 690 is 1 with a remainder of 70.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 690 from 760 to get 70.
Grab the next digit (5) from the dividend, add it to 70, then carry on: 705 / 690

Moving on to step 4:
The number 690 fits into 705 1 times, leaving a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 690 from 705 and we're left with 15.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 690

Advancing to step 5:
If we divide 150 by 690, we get 0 and a remainder of 150.
The next digit of our result is 0. 
Result so far: 110.0
Deduct 0 from 150 and we're left with 150.
Take the next digit (8) from the dividend and append it to 150, then repeat: 1508 / 690

Let's proceed to step 6:
When dividing 1508 by 690, we get 2 with a remainder of 128.
Put 2 as the next digit of the answer. 
Result so far: 1102.0
Deduct 1380 from 1508 and we're left with 128.
Fetch the next digit (4) from the dividend, attach it to 128 and continue: 1284 / 690

Let's proceed to step 7:
690 can be fit into 1284 1 times, resulting in a remainder of 594.
The number 1 becomes the next digit in our result. 
Result so far: 11021.0
Subtract 690 from 1284 to get 594.
Take the next digit (7) from the dividend and append it to 594, then repeat: 5947 / 690

Going ahead to step 8:
If we divide 5947 by 690, we get 8 and a remainder of 427.
Use 8 as the next digit of our solution. 
Result so far: 110218.0
If we take 5520 away from 5947, we end up with 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

Moving on to step 9:
If we divide 4270 by 690, we get 6 and a remainder of 130.
The number 6 becomes the next digit in our result. 
Result so far: 110218.6
If we take 4140 away from 4270, we end up 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.

Advancing to step 10:
When dividing 1300 by 690, we get 1 with a remainder of 610.
Write down 1 as next digit of the result. 
Result so far: 110218.61
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.

Let's proceed to step 11:
When dividing 6100 by 690, we get 8 with a remainder of 580.
Write down 8 as next digit of the result. 
Result so far: 110218.618
Subtracting 5520 from 6100 leaves us with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Advancing to step 12:
When dividing 5800 by 690, we get 8 with a remainder of 280.
Use 8 as the next digit of our solution. 
Result so far: 110218.6188
Subtracting 5520 from 5800 leaves us with 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 110218.6188, with a leftover of 0.0028.
