The aim is to understand the frequency of 978 in 66132657.

Step 1:
The number 978 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 978

Let's proceed to step 2:
66 divided by 978 is 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Fetch the next digit (1) from the dividend, attach it to 66 and continue: 661 / 978

Moving on to step 3:
978 goes into 661 0 times with a remainder of 661.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 661 to get 661.
Grab the next digit (3) from the dividend, add it to 661, then carry on: 6613 / 978

On to step 4:
The number 978 fits into 6613 6 times, leaving a remainder of 745.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 5868 from 6613 leaves us with 745.
Grab the next digit (2) from the dividend, add it to 745, then carry on: 7452 / 978

Going ahead to step 5:
7452 divided by 978 is 7 with a remainder of 606.
The number 7 becomes the next digit in our result. 
Result so far: 67.0
Subtract 6846 from 7452 to get 606.
Take the next digit (6) from the dividend and append it to 606, then repeat: 6066 / 978

Advancing to step 6:
If we divide 6066 by 978, we get 6 and a remainder of 198.
The number 6 becomes the next digit in our result. 
Result so far: 676.0
Subtract 5868 from 6066 to get 198.
Grab the next digit (5) from the dividend, add it to 198, then carry on: 1985 / 978

Advancing to step 7:
If we divide 1985 by 978, we get 2 and a remainder of 29.
Put 2 as the next digit of the answer. 
Result so far: 6762.0
If we take 1956 away from 1985, we end up with 29.
Take the next digit (7) from the dividend and append it to 29, then repeat: 297 / 978

Step 8:
297 divided by 978 is 0 with a remainder of 297.
The number 0 becomes the next digit in our result. 
Result so far: 67620.0
Subtract 0 from 297 to get 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Going ahead to step 9:
When dividing 2970 by 978, we get 3 with a remainder of 36.
Use 3 as the next digit of our solution. 
Result so far: 67620.3
If we subtract 2934 from 2970, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 10:
The number 978 fits into 360 0 times, leaving a remainder of 360.
Write down 0 as next digit of the result. 
Result so far: 67620.3
The remainder is 360 after subtracting 0 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 11:
978 goes into 3600 3 times with a remainder of 666.
Use 3 as the next digit of our solution. 
Result so far: 67620.303
If we subtract 2934 from 3600, we get 666.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6660, and continue the process.

Moving on to step 12:
978 goes into 6660 6 times with a remainder of 792.
Record the quotient 6 as the next digit in the result. 
Result so far: 67620.3036
If we subtract 5868 from 6660, we get 792.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7920, and continue the process.

Moving on to step 13:
978 goes into 7920 8 times with a remainder of 96.
Record the quotient 8 as the next digit in the result. 
Result so far: 67620.30368
If we take 7824 away from 7920, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 14:
The number 978 fits into 960 0 times, leaving a remainder of 960.
The next digit of our result is 0. 
Result so far: 67620.30368
Deduct 0 from 960 and we're left with 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9600, and continue the process.

Step 15:
If we divide 9600 by 978, we get 9 and a remainder of 798.
Put 9 as the next digit of the answer. 
Result so far: 67620.3036809
Subtract 8802 from 9600 to get 798.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7980, and continue the process.

Advancing to step 16:
If we divide 7980 by 978, we get 8 and a remainder of 156.
Write down 8 as next digit of the result. 
Result so far: 67620.30368098
Subtracting 7824 from 7980 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

The quotient of the division is 67620.30368098, and the remainder is 1.56e-07.
