We look at the division of 63627665 by 931 
The aim is to understand the frequency of 931 in 63627665.

Advancing to step 1:
931 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 931

Step 2:
The number 931 fits into 63 0 times, leaving a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Bring next digit (6) of the dividend behind the 63 and repeat the process: 636 / 931

Advancing to step 3:
931 can be fit into 636 0 times, resulting in a remainder of 636.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 636 and we're left with 636.
Grab the next digit (2) from the dividend, add it to 636, then carry on: 6362 / 931

On to step 4:
When dividing 6362 by 931, we get 6 with a remainder of 776.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 5586 from 6362 to get 776.
Fetch the next digit (7) from the dividend, attach it to 776 and continue: 7767 / 931

Let's proceed to step 5:
The number 931 fits into 7767 8 times, leaving a remainder of 319.
The number 8 becomes the next digit in our result. 
Result so far: 68.0
Subtracting 7448 from 7767 leaves us with 319.
Bring next digit (6) of the dividend behind the 319 and repeat the process: 3196 / 931

Let's proceed to step 6:
If we divide 3196 by 931, we get 3 and a remainder of 403.
Write down 3 as next digit of the result. 
Result so far: 683.0
The remainder is 403 after subtracting 2793 from 3196.
Take the next digit (6) from the dividend and append it to 403, then repeat: 4036 / 931

Let's proceed to step 7:
If we divide 4036 by 931, we get 4 and a remainder of 312.
The number 4 becomes the next digit in our result. 
Result so far: 6834.0
Subtract 3724 from 4036 to get 312.
Append the next digit (5) from the dividend to 312 and continue with: 3125 / 931

Step 8:
If we divide 3125 by 931, we get 3 and a remainder of 332.
Use 3 as the next digit of our solution. 
Result so far: 68343.0
If we take 2793 away from 3125, we end up with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Step 9:
The number 931 fits into 3320 3 times, leaving a remainder of 527.
Record the quotient 3 as the next digit in the result. 
Result so far: 68343.3
If we take 2793 away from 3320, we end up with 527.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5270, and continue the process.

Moving on to step 10:
The number 931 fits into 5270 5 times, leaving a remainder of 615.
Record the quotient 5 as the next digit in the result. 
Result so far: 68343.35
Subtracting 4655 from 5270 leaves us with 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

On to step 11:
931 goes into 6150 6 times with a remainder of 564.
Record the quotient 6 as the next digit in the result. 
Result so far: 68343.356
Subtracting 5586 from 6150 leaves us with 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

On to step 12:
If we divide 5640 by 931, we get 6 and a remainder of 54.
Put 6 as the next digit of the answer. 
Result so far: 68343.3566
Subtract 5586 from 5640 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

After the division, we end up with 68343.3566 and a remainder of 0.00054.
