We're dividing 39779940 by 979 
The aim is to understand the frequency of 979 in 39779940.

Advancing to step 1:
The number 979 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 979

Advancing to step 2:
979 can be fit into 39 0 times, resulting in a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Include the next digit (7) from the dividend after 39, then repeat: 397 / 979

Advancing to step 3:
979 goes into 397 0 times with a remainder of 397.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 397 and we're left with 397.
Bring next digit (7) of the dividend behind the 397 and repeat the process: 3977 / 979

Going ahead to step 4:
When dividing 3977 by 979, we get 4 with a remainder of 61.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 3916 from 3977 and we're left with 61.
Bring next digit (9) of the dividend behind the 61 and repeat the process: 619 / 979

Going ahead to step 5:
619 divided by 979 is 0 with a remainder of 619.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
Deduct 0 from 619 and we're left with 619.
Take the next digit (9) from the dividend and append it to 619, then repeat: 6199 / 979

Let's proceed to step 6:
When dividing 6199 by 979, we get 6 with a remainder of 325.
The next digit of our result is 6. 
Result so far: 406.0
If we take 5874 away from 6199, we end up with 325.
Fetch the next digit (4) from the dividend, attach it to 325 and continue: 3254 / 979

Let's proceed to step 7:
979 can be fit into 3254 3 times, resulting in a remainder of 317.
The next digit of our result is 3. 
Result so far: 4063.0
If we take 2937 away from 3254, we end up with 317.
Append the next digit (0) from the dividend to 317 and continue with: 3170 / 979

Moving on to step 8:
The number 979 fits into 3170 3 times, leaving a remainder of 233.
Record the quotient 3 as the next digit in the result. 
Result so far: 40633.0
Deduct 2937 from 3170 and we're left with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Going ahead to step 9:
2330 divided by 979 is 2 with a remainder of 372.
The next digit of our result is 2. 
Result so far: 40633.2
Deduct 1958 from 2330 and we're left with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Let's proceed to step 10:
3720 divided by 979 is 3 with a remainder of 783.
Put 3 as the next digit of the answer. 
Result so far: 40633.23
If we take 2937 away from 3720, we end up with 783.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7830, and continue the process.

Step 11:
The number 979 fits into 7830 7 times, leaving a remainder of 977.
Record the quotient 7 as the next digit in the result. 
Result so far: 40633.237
If we take 6853 away from 7830, we end up with 977.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9770, and continue the process.

On to step 12:
If we divide 9770 by 979, we get 9 and a remainder of 959.
Put 9 as the next digit of the answer. 
Result so far: 40633.2379
If we subtract 8811 from 9770, we get 959.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9590, and continue the process.

Moving on to step 13:
979 goes into 9590 9 times with a remainder of 779.
Write down 9 as next digit of the result. 
Result so far: 40633.23799
Subtracting 8811 from 9590 leaves us with 779.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7790, and continue the process.

The final result is 40633.23799 with a remainder of 0.000779.
