We look at the division of 16608745 by 931 
The aim is to understand the frequency of 931 in 16608745.

Going ahead to step 1:
The number 931 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 931

Step 2:
931 goes into 16 0 times with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Include the next digit (6) from the dividend after 16, then repeat: 166 / 931

Going ahead to step 3:
The number 931 fits into 166 0 times, leaving a remainder of 166.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 166 to get 166.
Fetch the next digit (0) from the dividend, attach it to 166 and continue: 1660 / 931

Advancing to step 4:
931 can be fit into 1660 1 times, resulting in a remainder of 729.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 931 from 1660 leaves us with 729.
Take the next digit (8) from the dividend and append it to 729, then repeat: 7298 / 931

On to step 5:
931 can be fit into 7298 7 times, resulting in a remainder of 781.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Deduct 6517 from 7298 and we're left with 781.
Fetch the next digit (7) from the dividend, attach it to 781 and continue: 7817 / 931

Advancing to step 6:
When dividing 7817 by 931, we get 8 with a remainder of 369.
Put 8 as the next digit of the answer. 
Result so far: 178.0
The remainder is 369 after subtracting 7448 from 7817.
Take the next digit (4) from the dividend and append it to 369, then repeat: 3694 / 931

On to step 7:
If we divide 3694 by 931, we get 3 and a remainder of 901.
The next digit of our result is 3. 
Result so far: 1783.0
Deduct 2793 from 3694 and we're left with 901.
Fetch the next digit (5) from the dividend, attach it to 901 and continue: 9015 / 931

Going ahead to step 8:
931 goes into 9015 9 times with a remainder of 636.
The next digit of our result is 9. 
Result so far: 17839.0
The remainder is 636 after subtracting 8379 from 9015.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Going ahead to step 9:
931 goes into 6360 6 times with a remainder of 774.
The number 6 becomes the next digit in our result. 
Result so far: 17839.6
If we subtract 5586 from 6360, we get 774.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7740, and continue the process.

Going ahead to step 10:
7740 divided by 931 is 8 with a remainder of 292.
Put 8 as the next digit of the answer. 
Result so far: 17839.68
Deduct 7448 from 7740 and we're left with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

On to step 11:
931 can be fit into 2920 3 times, resulting in a remainder of 127.
Write down 3 as next digit of the result. 
Result so far: 17839.683
Deduct 2793 from 2920 and we're left with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Step 12:
When dividing 1270 by 931, we get 1 with a remainder of 339.
Use 1 as the next digit of our solution. 
Result so far: 17839.6831
If we take 931 away from 1270, we end up with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Step 13:
931 can be fit into 3390 3 times, resulting in a remainder of 597.
The next digit of our result is 3. 
Result so far: 17839.68313
Subtracting 2793 from 3390 leaves us with 597.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5970, and continue the process.

Advancing to step 14:
When dividing 5970 by 931, we get 6 with a remainder of 384.
The number 6 becomes the next digit in our result. 
Result so far: 17839.683136
The remainder is 384 after subtracting 5586 from 5970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

On to step 15:
931 goes into 3840 4 times with a remainder of 116.
The number 4 becomes the next digit in our result. 
Result so far: 17839.6831364
The remainder is 116 after subtracting 3724 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Let's proceed to step 16:
The number 931 fits into 1160 1 times, leaving a remainder of 229.
The number 1 becomes the next digit in our result. 
Result so far: 17839.68313641
If we take 931 away from 1160, we end up with 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

The quotient of the division is 17839.68313641, and the remainder is 2.29e-07.
