We look at the division of 66602367 by 978 
The aim is to understand the frequency of 978 in 66602367.

Step 1:
The number 978 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 978

On to step 2:
When dividing 66 by 978, we get 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Fetch the next digit (6) from the dividend, attach it to 66 and continue: 666 / 978

Advancing to step 3:
978 goes into 666 0 times with a remainder of 666.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 666, we get 666.
Append the next digit (0) from the dividend to 666 and continue with: 6660 / 978

Advancing to step 4:
If we divide 6660 by 978, we get 6 and a remainder of 792.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 5868 from 6660 leaves us with 792.
Include the next digit (2) from the dividend after 792, then repeat: 7922 / 978

Moving on to step 5:
978 goes into 7922 8 times with a remainder of 98.
The number 8 becomes the next digit in our result. 
Result so far: 68.0
Subtracting 7824 from 7922 leaves us with 98.
Include the next digit (3) from the dividend after 98, then repeat: 983 / 978

Moving on to step 6:
978 goes into 983 1 times with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 681.0
If we take 978 away from 983, we end up with 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 978

Let's proceed to step 7:
When dividing 56 by 978, we get 0 with a remainder of 56.
Use 0 as the next digit of our solution. 
Result so far: 6810.0
If we subtract 0 from 56, we get 56.
Fetch the next digit (7) from the dividend, attach it to 56 and continue: 567 / 978

Moving on to step 8:
If we divide 567 by 978, we get 0 and a remainder of 567.
The next digit of our result is 0. 
Result so far: 68100.0
Subtract 0 from 567 to get 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

Moving on to step 9:
978 goes into 5670 5 times with a remainder of 780.
The next digit of our result is 5. 
Result so far: 68100.5
If we take 4890 away from 5670, we end up with 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

On to step 10:
978 goes into 7800 7 times with a remainder of 954.
Use 7 as the next digit of our solution. 
Result so far: 68100.57
Subtract 6846 from 7800 to get 954.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9540, and continue the process.

On to step 11:
If we divide 9540 by 978, we get 9 and a remainder of 738.
Use 9 as the next digit of our solution. 
Result so far: 68100.579
Subtract 8802 from 9540 to get 738.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7380, and continue the process.

Going ahead to step 12:
When dividing 7380 by 978, we get 7 with a remainder of 534.
Put 7 as the next digit of the answer. 
Result so far: 68100.5797
The remainder is 534 after subtracting 6846 from 7380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Going ahead to step 13:
978 goes into 5340 5 times with a remainder of 450.
Write down 5 as next digit of the result. 
Result so far: 68100.57975
Subtracting 4890 from 5340 leaves us with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Going ahead to step 14:
978 can be fit into 4500 4 times, resulting in a remainder of 588.
Use 4 as the next digit of our solution. 
Result so far: 68100.579754
The remainder is 588 after subtracting 3912 from 4500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Step 15:
When dividing 5880 by 978, we get 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 68100.5797546
If we subtract 5868 from 5880, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 16:
120 divided by 978 is 0 with a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 68100.5797546
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Our division results in 68100.5797546 with a remaining 1.2e-07.
