1660725 divided by 931 
The aim is to understand the frequency of 931 in 1660725.

Moving on to step 1:
When dividing 1 by 931, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 931

On to step 2:
If we divide 16 by 931, we get 0 and a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Take the next digit (6) from the dividend and append it to 16, then repeat: 166 / 931

On to step 3:
166 divided by 931 is 0 with a remainder of 166.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 166 after subtracting 0 from 166.
Append the next digit (0) from the dividend to 166 and continue with: 1660 / 931

Let's proceed to step 4:
When dividing 1660 by 931, we get 1 with a remainder of 729.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 931 away from 1660, we end up with 729.
Bring next digit (7) of the dividend behind the 729 and repeat the process: 7297 / 931

Going ahead to step 5:
The number 931 fits into 7297 7 times, leaving a remainder of 780.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Deduct 6517 from 7297 and we're left with 780.
Fetch the next digit (2) from the dividend, attach it to 780 and continue: 7802 / 931

Advancing to step 6:
The number 931 fits into 7802 8 times, leaving a remainder of 354.
The next digit of our result is 8. 
Result so far: 178.0
Deduct 7448 from 7802 and we're left with 354.
Take the next digit (5) from the dividend and append it to 354, then repeat: 3545 / 931

Going ahead to step 7:
931 can be fit into 3545 3 times, resulting in a remainder of 752.
The number 3 becomes the next digit in our result. 
Result so far: 1783.0
Subtracting 2793 from 3545 leaves us with 752.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

Moving on to step 8:
When dividing 7520 by 931, we get 8 with a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 1783.8
If we take 7448 away from 7520, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 9:
When dividing 720 by 931, we get 0 with a remainder of 720.
Write down 0 as next digit of the result. 
Result so far: 1783.8
If we take 0 away from 720, we end up with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Moving on to step 10:
7200 divided by 931 is 7 with a remainder of 683.
The number 7 becomes the next digit in our result. 
Result so far: 1783.807
If we subtract 6517 from 7200, we get 683.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6830, and continue the process.

Advancing to step 11:
The number 931 fits into 6830 7 times, leaving a remainder of 313.
Use 7 as the next digit of our solution. 
Result so far: 1783.8077
If we take 6517 away from 6830, we end up with 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

After the division, we end up with 1783.8077 and a remainder of 0.00313.
