69591066 ÷ 687 
The aim is to understand the frequency of 687 in 69591066.

Step 1:
687 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 687

Let's proceed to step 2:
687 can be fit into 69 0 times, resulting in a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 69, we end up with 69.
Take the next digit (5) from the dividend and append it to 69, then repeat: 695 / 687

Let's proceed to step 3:
If we divide 695 by 687, we get 1 and a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 687 from 695, we get 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 687

Advancing to step 4:
687 can be fit into 89 0 times, resulting in a remainder of 89.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 89 leaves us with 89.
Include the next digit (1) from the dividend after 89, then repeat: 891 / 687

Step 5:
891 divided by 687 is 1 with a remainder of 204.
Use 1 as the next digit of our solution. 
Result so far: 101.0
Deduct 687 from 891 and we're left with 204.
Append the next digit (0) from the dividend to 204 and continue with: 2040 / 687

Let's proceed to step 6:
687 goes into 2040 2 times with a remainder of 666.
Put 2 as the next digit of the answer. 
Result so far: 1012.0
If we subtract 1374 from 2040, we get 666.
Include the next digit (6) from the dividend after 666, then repeat: 6666 / 687

Advancing to step 7:
The number 687 fits into 6666 9 times, leaving a remainder of 483.
The next digit of our result is 9. 
Result so far: 10129.0
Deduct 6183 from 6666 and we're left with 483.
Include the next digit (6) from the dividend after 483, then repeat: 4836 / 687

Let's proceed to step 8:
The number 687 fits into 4836 7 times, leaving a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 101297.0
Deduct 4809 from 4836 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 9:
687 goes into 270 0 times with a remainder of 270.
The next digit of our result is 0. 
Result so far: 101297.0
Deduct 0 from 270 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.

Advancing to step 10:
687 can be fit into 2700 3 times, resulting in a remainder of 639.
The next digit of our result is 3. 
Result so far: 101297.03
Subtract 2061 from 2700 to get 639.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6390, and continue the process.

Advancing to step 11:
If we divide 6390 by 687, we get 9 and a remainder of 207.
The number 9 becomes the next digit in our result. 
Result so far: 101297.039
Subtract 6183 from 6390 to get 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Let's proceed to step 12:
2070 divided by 687 is 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 101297.0393
If we take 2061 away from 2070, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 13:
When dividing 90 by 687, we get 0 with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 101297.0393
Deduct 0 from 90 and we're left 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.

Let's proceed to step 14:
687 can be fit into 900 1 times, resulting in a remainder of 213.
Use 1 as the next digit of our solution. 
Result so far: 101297.039301
If we subtract 687 from 900, we get 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Moving on to step 15:
When dividing 2130 by 687, we get 3 with a remainder of 69.
The number 3 becomes the next digit in our result. 
Result so far: 101297.0393013
The remainder is 69 after subtracting 2061 from 2130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 16:
The number 687 fits into 690 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 101297.03930131
The remainder is 3 after subtracting 687 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

After the division, we end up with 101297.03930131 and a remainder of 3e-09.
