We divide 63758731 by 686
The aim is to understand the frequency of 686 in 63758731.

Step 1:
6 divided by 686 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 686

On to step 2:
686 goes into 63 0 times with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Bring next digit (7) of the dividend behind the 63 and repeat the process: 637 / 686

Step 3:
When dividing 637 by 686, we get 0 with a remainder of 637.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 637, we get 637.
Fetch the next digit (5) from the dividend, attach it to 637 and continue: 6375 / 686

Step 4:
686 goes into 6375 9 times with a remainder of 201.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 6174 from 6375 leaves us with 201.
Take the next digit (8) from the dividend and append it to 201, then repeat: 2018 / 686

Advancing to step 5:
686 can be fit into 2018 2 times, resulting in a remainder of 646.
Record the quotient 2 as the next digit in the result. 
Result so far: 92.0
If we take 1372 away from 2018, we end up with 646.
Include the next digit (7) from the dividend after 646, then repeat: 6467 / 686

Moving on to step 6:
The number 686 fits into 6467 9 times, leaving a remainder of 293.
Put 9 as the next digit of the answer. 
Result so far: 929.0
The remainder is 293 after subtracting 6174 from 6467.
Bring next digit (3) of the dividend behind the 293 and repeat the process: 2933 / 686

Moving on to step 7:
2933 divided by 686 is 4 with a remainder of 189.
The next digit of our result is 4. 
Result so far: 9294.0
Deduct 2744 from 2933 and we're left with 189.
Append the next digit (1) from the dividend to 189 and continue with: 1891 / 686

Going ahead to step 8:
686 goes into 1891 2 times with a remainder of 519.
The next digit of our result is 2. 
Result so far: 92942.0
Subtracting 1372 from 1891 leaves us with 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

Step 9:
When dividing 5190 by 686, we get 7 with a remainder of 388.
The number 7 becomes the next digit in our result. 
Result so far: 92942.7
If we subtract 4802 from 5190, we get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Moving on to step 10:
When dividing 3880 by 686, we get 5 with a remainder of 450.
The number 5 becomes the next digit in our result. 
Result so far: 92942.75
If we take 3430 away from 3880, we end up with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 11:
686 can be fit into 4500 6 times, resulting in a remainder of 384.
The number 6 becomes the next digit in our result. 
Result so far: 92942.756
If we take 4116 away from 4500, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Let's proceed to step 12:
When dividing 3840 by 686, we get 5 with a remainder of 410.
Put 5 as the next digit of the answer. 
Result so far: 92942.7565
Subtract 3430 from 3840 to get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Let's proceed to step 13:
4100 divided by 686 is 5 with a remainder of 670.
The next digit of our result is 5. 
Result so far: 92942.75655
Subtract 3430 from 4100 to get 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

In conclusion, the division gives 92942.75655 with a balance of 0.00067.
