78338940 divided by 979 
The aim is to understand the frequency of 979 in 78338940.

Going ahead to step 1:
7 divided by 979 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 979

Going ahead to step 2:
When dividing 78 by 979, we get 0 with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Grab the next digit (3) from the dividend, add it to 78, then carry on: 783 / 979

On to step 3:
783 divided by 979 is 0 with a remainder of 783.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 783 leaves us with 783.
Take the next digit (3) from the dividend and append it to 783, then repeat: 7833 / 979

Step 4:
If we divide 7833 by 979, we get 8 and a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 7832 from 7833 leaves us with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 979

Step 5:
If we divide 18 by 979, we get 0 and a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 80.0
The remainder is 18 after subtracting 0 from 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 979

Moving on to step 6:
979 goes into 189 0 times with a remainder of 189.
Record the quotient 0 as the next digit in the result. 
Result so far: 800.0
Deduct 0 from 189 and we're left with 189.
Take the next digit (4) from the dividend and append it to 189, then repeat: 1894 / 979

On to step 7:
If we divide 1894 by 979, we get 1 and a remainder of 915.
Put 1 as the next digit of the answer. 
Result so far: 8001.0
If we subtract 979 from 1894, we get 915.
Include the next digit (0) from the dividend after 915, then repeat: 9150 / 979

Step 8:
979 goes into 9150 9 times with a remainder of 339.
Record the quotient 9 as the next digit in the result. 
Result so far: 80019.0
The remainder is 339 after subtracting 8811 from 9150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Step 9:
979 can be fit into 3390 3 times, resulting in a remainder of 453.
Record the quotient 3 as the next digit in the result. 
Result so far: 80019.3
If we subtract 2937 from 3390, we get 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

Advancing to step 10:
4530 divided by 979 is 4 with a remainder of 614.
Use 4 as the next digit of our solution. 
Result so far: 80019.34
The remainder is 614 after subtracting 3916 from 4530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Step 11:
The number 979 fits into 6140 6 times, leaving a remainder of 266.
The next digit of our result is 6. 
Result so far: 80019.346
If we subtract 5874 from 6140, we get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Step 12:
The number 979 fits into 2660 2 times, leaving a remainder of 702.
Use 2 as the next digit of our solution. 
Result so far: 80019.3462
If we take 1958 away from 2660, we end up with 702.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7020, and continue the process.

Step 13:
979 goes into 7020 7 times with a remainder of 167.
Record the quotient 7 as the next digit in the result. 
Result so far: 80019.34627
Subtract 6853 from 7020 to get 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Moving on to step 14:
If we divide 1670 by 979, we get 1 and a remainder of 691.
Record the quotient 1 as the next digit in the result. 
Result so far: 80019.346271
If we subtract 979 from 1670, we get 691.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6910, and continue the process.

Advancing to step 15:
979 can be fit into 6910 7 times, resulting in a remainder of 57.
Write down 7 as next digit of the result. 
Result so far: 80019.3462717
The remainder is 57 after subtracting 6853 from 6910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 16:
570 divided by 979 is 0 with a remainder of 570.
Record the quotient 0 as the next digit in the result. 
Result so far: 80019.3462717
Subtract 0 from 570 to get 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

The final outcome is 80019.3462717, with a leftover of 5.7e-07.
