We look at the division of 72927037 by 631 
The aim is to understand the frequency of 631 in 72927037.

Going ahead to step 1:
The number 631 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 631

On to step 2:
The number 631 fits into 72 0 times, leaving a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Include the next digit (9) from the dividend after 72, then repeat: 729 / 631

On to step 3:
631 can be fit into 729 1 times, resulting in a remainder of 98.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 631 from 729, we get 98.
Append the next digit (2) from the dividend to 98 and continue with: 982 / 631

Let's proceed to step 4:
The number 631 fits into 982 1 times, leaving a remainder of 351.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 631 from 982 and we're left with 351.
Grab the next digit (7) from the dividend, add it to 351, then carry on: 3517 / 631

Step 5:
631 can be fit into 3517 5 times, resulting in a remainder of 362.
Write down 5 as next digit of the result. 
Result so far: 115.0
If we subtract 3155 from 3517, we get 362.
Include the next digit (0) from the dividend after 362, then repeat: 3620 / 631

Step 6:
631 goes into 3620 5 times with a remainder of 465.
Record the quotient 5 as the next digit in the result. 
Result so far: 1155.0
The remainder is 465 after subtracting 3155 from 3620.
Bring next digit (3) of the dividend behind the 465 and repeat the process: 4653 / 631

Going ahead to step 7:
631 can be fit into 4653 7 times, resulting in a remainder of 236.
Put 7 as the next digit of the answer. 
Result so far: 11557.0
If we take 4417 away from 4653, we end up with 236.
Bring next digit (7) of the dividend behind the 236 and repeat the process: 2367 / 631

On to step 8:
When dividing 2367 by 631, we get 3 with a remainder of 474.
Record the quotient 3 as the next digit in the result. 
Result so far: 115573.0
If we subtract 1893 from 2367, we get 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Going ahead to step 9:
631 can be fit into 4740 7 times, resulting in a remainder of 323.
The number 7 becomes the next digit in our result. 
Result so far: 115573.7
If we subtract 4417 from 4740, we get 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Let's proceed to step 10:
When dividing 3230 by 631, we get 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 115573.75
Deduct 3155 from 3230 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 11:
If we divide 750 by 631, we get 1 and a remainder of 119.
Write down 1 as next digit of the result. 
Result so far: 115573.751
Deduct 631 from 750 and we're left with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Step 12:
The number 631 fits into 1190 1 times, leaving a remainder of 559.
Write down 1 as next digit of the result. 
Result so far: 115573.7511
If we take 631 away from 1190, we end up with 559.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5590, and continue the process.

The final result is 115573.7511 with a remainder of 0.00559.
