We divide 80680016 by 689
The aim is to understand the frequency of 689 in 80680016.

Moving on to step 1:
689 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 689

Advancing to step 2:
80 divided by 689 is 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Grab the next digit (6) from the dividend, add it to 80, then carry on: 806 / 689

Let's proceed to step 3:
When dividing 806 by 689, we get 1 with a remainder of 117.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 689 from 806 and we're left with 117.
Include the next digit (8) from the dividend after 117, then repeat: 1178 / 689

Let's proceed to step 4:
The number 689 fits into 1178 1 times, leaving a remainder of 489.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we take 689 away from 1178, we end up with 489.
Bring next digit (0) of the dividend behind the 489 and repeat the process: 4890 / 689

Going ahead to step 5:
689 can be fit into 4890 7 times, resulting in a remainder of 67.
Write down 7 as next digit of the result. 
Result so far: 117.0
The remainder is 67 after subtracting 4823 from 4890.
Fetch the next digit (0) from the dividend, attach it to 67 and continue: 670 / 689

Going ahead to step 6:
689 can be fit into 670 0 times, resulting in a remainder of 670.
Use 0 as the next digit of our solution. 
Result so far: 1170.0
If we subtract 0 from 670, we get 670.
Bring next digit (1) of the dividend behind the 670 and repeat the process: 6701 / 689

Going ahead to step 7:
689 can be fit into 6701 9 times, resulting in a remainder of 500.
Record the quotient 9 as the next digit in the result. 
Result so far: 11709.0
Subtracting 6201 from 6701 leaves us with 500.
Append the next digit (6) from the dividend to 500 and continue with: 5006 / 689

Advancing to step 8:
When dividing 5006 by 689, we get 7 with a remainder of 183.
The next digit of our result is 7. 
Result so far: 117097.0
If we take 4823 away from 5006, we end up with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Moving on to step 9:
689 can be fit into 1830 2 times, resulting in a remainder of 452.
The next digit of our result is 2. 
Result so far: 117097.2
Deduct 1378 from 1830 and we're left with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Moving on to step 10:
If we divide 4520 by 689, we get 6 and a remainder of 386.
Put 6 as the next digit of the answer. 
Result so far: 117097.26
Subtracting 4134 from 4520 leaves us with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Advancing to step 11:
If we divide 3860 by 689, we get 5 and a remainder of 415.
The next digit of our result is 5. 
Result so far: 117097.265
Subtracting 3445 from 3860 leaves us with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Advancing to step 12:
If we divide 4150 by 689, we get 6 and a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 117097.2656
Subtract 4134 from 4150 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
When dividing 160 by 689, we get 0 with a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 117097.2656
Subtract 0 from 160 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 14:
The number 689 fits into 1600 2 times, leaving a remainder of 222.
The next digit of our result is 2. 
Result so far: 117097.265602
If we subtract 1378 from 1600, we get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Step 15:
The number 689 fits into 2220 3 times, leaving a remainder of 153.
Put 3 as the next digit of the answer. 
Result so far: 117097.2656023
Subtracting 2067 from 2220 leaves us with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Going ahead to step 16:
689 can be fit into 1530 2 times, resulting in a remainder of 152.
Write down 2 as next digit of the result. 
Result so far: 117097.26560232
If we subtract 1378 from 1530, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

The quotient of the division is 117097.26560232, and the remainder is 1.52e-07.
