We look at the division of 89138982 by 978 
The aim is to understand the frequency of 978 in 89138982.

Advancing to step 1:
If we divide 8 by 978, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 978

Step 2:
89 divided by 978 is 0 with a remainder of 89.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 89 leaves us with 89.
Include the next digit (1) from the dividend after 89, then repeat: 891 / 978

Going ahead to step 3:
The number 978 fits into 891 0 times, leaving a remainder of 891.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 891 leaves us with 891.
Bring next digit (3) of the dividend behind the 891 and repeat the process: 8913 / 978

On to step 4:
978 can be fit into 8913 9 times, resulting in a remainder of 111.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 111 after subtracting 8802 from 8913.
Append the next digit (8) from the dividend to 111 and continue with: 1118 / 978

Moving on to step 5:
The number 978 fits into 1118 1 times, leaving a remainder of 140.
Put 1 as the next digit of the answer. 
Result so far: 91.0
If we take 978 away from 1118, we end up with 140.
Bring next digit (9) of the dividend behind the 140 and repeat the process: 1409 / 978

On to step 6:
When dividing 1409 by 978, we get 1 with a remainder of 431.
Record the quotient 1 as the next digit in the result. 
Result so far: 911.0
If we take 978 away from 1409, we end up with 431.
Take the next digit (8) from the dividend and append it to 431, then repeat: 4318 / 978

Advancing to step 7:
If we divide 4318 by 978, we get 4 and a remainder of 406.
The number 4 becomes the next digit in our result. 
Result so far: 9114.0
If we subtract 3912 from 4318, we get 406.
Append the next digit (2) from the dividend to 406 and continue with: 4062 / 978

Moving on to step 8:
If we divide 4062 by 978, we get 4 and a remainder of 150.
The next digit of our result is 4. 
Result so far: 91144.0
The remainder is 150 after subtracting 3912 from 4062.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 9:
The number 978 fits into 1500 1 times, leaving a remainder of 522.
Put 1 as the next digit of the answer. 
Result so far: 91144.1
Subtracting 978 from 1500 leaves us with 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

On to step 10:
978 can be fit into 5220 5 times, resulting in a remainder of 330.
Write down 5 as next digit of the result. 
Result so far: 91144.15
If we take 4890 away from 5220, we end up with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 11:
978 goes into 3300 3 times with a remainder of 366.
The number 3 becomes the next digit in our result. 
Result so far: 91144.153
Deduct 2934 from 3300 and we're left with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Going ahead to step 12:
The number 978 fits into 3660 3 times, leaving a remainder of 726.
The number 3 becomes the next digit in our result. 
Result so far: 91144.1533
Deduct 2934 from 3660 and we're left with 726.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7260, and continue the process.

In conclusion, the division gives 91144.1533 with a balance of 0.00726.
