We look at the division of 31805291 by 979 
The aim is to understand the frequency of 979 in 31805291.

Going ahead to step 1:
The number 979 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 979

Let's proceed to step 2:
When dividing 31 by 979, we get 0 with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Bring next digit (8) of the dividend behind the 31 and repeat the process: 318 / 979

Let's proceed to step 3:
318 divided by 979 is 0 with a remainder of 318.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 318 and we're left with 318.
Take the next digit (0) from the dividend and append it to 318, then repeat: 3180 / 979

Let's proceed to step 4:
The number 979 fits into 3180 3 times, leaving a remainder of 243.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 2937 from 3180 and we're left with 243.
Append the next digit (5) from the dividend to 243 and continue with: 2435 / 979

Moving on to step 5:
979 can be fit into 2435 2 times, resulting in a remainder of 477.
Write down 2 as next digit of the result. 
Result so far: 32.0
Subtracting 1958 from 2435 leaves us with 477.
Include the next digit (2) from the dividend after 477, then repeat: 4772 / 979

Moving on to step 6:
If we divide 4772 by 979, we get 4 and a remainder of 856.
Record the quotient 4 as the next digit in the result. 
Result so far: 324.0
If we take 3916 away from 4772, we end up with 856.
Fetch the next digit (9) from the dividend, attach it to 856 and continue: 8569 / 979

On to step 7:
979 goes into 8569 8 times with a remainder of 737.
The next digit of our result is 8. 
Result so far: 3248.0
If we take 7832 away from 8569, we end up with 737.
Take the next digit (1) from the dividend and append it to 737, then repeat: 7371 / 979

Going ahead to step 8:
979 can be fit into 7371 7 times, resulting in a remainder of 518.
Record the quotient 7 as the next digit in the result. 
Result so far: 32487.0
Subtracting 6853 from 7371 leaves us with 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Moving on to step 9:
The number 979 fits into 5180 5 times, leaving a remainder of 285.
Record the quotient 5 as the next digit in the result. 
Result so far: 32487.5
If we take 4895 away from 5180, we end up with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Going ahead to step 10:
The number 979 fits into 2850 2 times, leaving a remainder of 892.
Put 2 as the next digit of the answer. 
Result so far: 32487.52
Subtracting 1958 from 2850 leaves us with 892.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8920, and continue the process.

Moving on to step 11:
When dividing 8920 by 979, we get 9 with a remainder of 109.
Write down 9 as next digit of the result. 
Result so far: 32487.529
Deduct 8811 from 8920 and we're left with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Let's proceed to step 12:
979 can be fit into 1090 1 times, resulting in a remainder of 111.
Use 1 as the next digit of our solution. 
Result so far: 32487.5291
If we subtract 979 from 1090, we get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Step 13:
If we divide 1110 by 979, we get 1 and a remainder of 131.
Record the quotient 1 as the next digit in the result. 
Result so far: 32487.52911
Deduct 979 from 1110 and we're left with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

After the division, we end up with 32487.52911 and a remainder of 0.000131.
