20180439 ÷ 978 
The aim is to understand the frequency of 978 in 20180439.

Going ahead to step 1:
If we divide 2 by 978, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 978

On to step 2:
The number 978 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Include the next digit (1) from the dividend after 20, then repeat: 201 / 978

Going ahead to step 3:
978 goes into 201 0 times with a remainder of 201.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 201 leaves us with 201.
Bring next digit (8) of the dividend behind the 201 and repeat the process: 2018 / 978

Going ahead to step 4:
The number 978 fits into 2018 2 times, leaving a remainder of 62.
The next digit of our result is 2. 
Result so far: 2.0
If we take 1956 away from 2018, we end up with 62.
Fetch the next digit (0) from the dividend, attach it to 62 and continue: 620 / 978

Moving on to step 5:
If we divide 620 by 978, we get 0 and a remainder of 620.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtracting 0 from 620 leaves us with 620.
Bring next digit (4) of the dividend behind the 620 and repeat the process: 6204 / 978

On to step 6:
978 goes into 6204 6 times with a remainder of 336.
Put 6 as the next digit of the answer. 
Result so far: 206.0
The remainder is 336 after subtracting 5868 from 6204.
Append the next digit (3) from the dividend to 336 and continue with: 3363 / 978

Let's proceed to step 7:
If we divide 3363 by 978, we get 3 and a remainder of 429.
Write down 3 as next digit of the result. 
Result so far: 2063.0
Deduct 2934 from 3363 and we're left with 429.
Fetch the next digit (9) from the dividend, attach it to 429 and continue: 4299 / 978

Moving on to step 8:
4299 divided by 978 is 4 with a remainder of 387.
Use 4 as the next digit of our solution. 
Result so far: 20634.0
If we take 3912 away from 4299, we end up with 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Advancing to step 9:
978 can be fit into 3870 3 times, resulting in a remainder of 936.
The next digit of our result is 3. 
Result so far: 20634.3
If we take 2934 away from 3870, we end up with 936.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9360, and continue the process.

Let's proceed to step 10:
978 can be fit into 9360 9 times, resulting in a remainder of 558.
The next digit of our result is 9. 
Result so far: 20634.39
Subtract 8802 from 9360 to get 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Step 11:
978 can be fit into 5580 5 times, resulting in a remainder of 690.
Put 5 as the next digit of the answer. 
Result so far: 20634.395
The remainder is 690 after subtracting 4890 from 5580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Let's proceed to step 12:
978 can be fit into 6900 7 times, resulting in a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 20634.3957
The remainder is 54 after subtracting 6846 from 6900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 13:
540 divided by 978 is 0 with a remainder of 540.
Record the quotient 0 as the next digit in the result. 
Result so far: 20634.3957
If we take 0 away from 540, we end up with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Step 14:
When dividing 5400 by 978, we get 5 with a remainder of 510.
The number 5 becomes the next digit in our result. 
Result so far: 20634.395705
Subtracting 4890 from 5400 leaves us with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Step 15:
978 can be fit into 5100 5 times, resulting in a remainder of 210.
Record the quotient 5 as the next digit in the result. 
Result so far: 20634.3957055
The remainder is 210 after subtracting 4890 from 5100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

In conclusion, the division gives 20634.3957055 with a balance of 2.1e-06.
