We divide 52186783 by 689
The aim is to understand the frequency of 689 in 52186783.

Moving on to step 1:
689 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 689

Step 2:
When dividing 52 by 689, we get 0 with a remainder of 52.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 52 after subtracting 0 from 52.
Fetch the next digit (1) from the dividend, attach it to 52 and continue: 521 / 689

Advancing to step 3:
521 divided by 689 is 0 with a remainder of 521.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 521 and we're left with 521.
Include the next digit (8) from the dividend after 521, then repeat: 5218 / 689

On to step 4:
689 can be fit into 5218 7 times, resulting in a remainder of 395.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 4823 from 5218 leaves us with 395.
Grab the next digit (6) from the dividend, add it to 395, then carry on: 3956 / 689

Moving on to step 5:
When dividing 3956 by 689, we get 5 with a remainder of 511.
Put 5 as the next digit of the answer. 
Result so far: 75.0
If we subtract 3445 from 3956, we get 511.
Include the next digit (7) from the dividend after 511, then repeat: 5117 / 689

Let's proceed to step 6:
5117 divided by 689 is 7 with a remainder of 294.
Write down 7 as next digit of the result. 
Result so far: 757.0
The remainder is 294 after subtracting 4823 from 5117.
Bring next digit (8) of the dividend behind the 294 and repeat the process: 2948 / 689

Moving on to step 7:
The number 689 fits into 2948 4 times, leaving a remainder of 192.
Record the quotient 4 as the next digit in the result. 
Result so far: 7574.0
Deduct 2756 from 2948 and we're left with 192.
Append the next digit (3) from the dividend to 192 and continue with: 1923 / 689

Let's proceed to step 8:
689 goes into 1923 2 times with a remainder of 545.
Write down 2 as next digit of the result. 
Result so far: 75742.0
Subtracting 1378 from 1923 leaves us with 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Advancing to step 9:
The number 689 fits into 5450 7 times, leaving a remainder of 627.
Record the quotient 7 as the next digit in the result. 
Result so far: 75742.7
Subtracting 4823 from 5450 leaves us with 627.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6270, and continue the process.

Moving on to step 10:
The number 689 fits into 6270 9 times, leaving a remainder of 69.
Use 9 as the next digit of our solution. 
Result so far: 75742.79
The remainder is 69 after subtracting 6201 from 6270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 11:
689 goes into 690 1 times with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 75742.791
If we subtract 689 from 690, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 12:
If we divide 10 by 689, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 75742.791
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 13:
The number 689 fits into 100 0 times, leaving a remainder of 100.
The next digit of our result is 0. 
Result so far: 75742.791
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

After the division, we end up with 75742.791 and a remainder of 0.0001.
