97521788 ÷ 989 
The aim is to understand the frequency of 989 in 97521788.

Step 1:
989 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 989

Let's proceed to step 2:
The number 989 fits into 97 0 times, leaving a remainder of 97.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 97 leaves us with 97.
Include the next digit (5) from the dividend after 97, then repeat: 975 / 989

Moving on to step 3:
If we divide 975 by 989, we get 0 and a remainder of 975.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 975 after subtracting 0 from 975.
Grab the next digit (2) from the dividend, add it to 975, then carry on: 9752 / 989

Let's proceed to step 4:
The number 989 fits into 9752 9 times, leaving a remainder of 851.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 8901 from 9752 leaves us with 851.
Grab the next digit (1) from the dividend, add it to 851, then carry on: 8511 / 989

Going ahead to step 5:
When dividing 8511 by 989, we get 8 with a remainder of 599.
Use 8 as the next digit of our solution. 
Result so far: 98.0
If we subtract 7912 from 8511, we get 599.
Fetch the next digit (7) from the dividend, attach it to 599 and continue: 5997 / 989

Moving on to step 6:
989 goes into 5997 6 times with a remainder of 63.
The next digit of our result is 6. 
Result so far: 986.0
Subtract 5934 from 5997 to get 63.
Fetch the next digit (8) from the dividend, attach it to 63 and continue: 638 / 989

Step 7:
989 can be fit into 638 0 times, resulting in a remainder of 638.
Put 0 as the next digit of the answer. 
Result so far: 9860.0
If we subtract 0 from 638, we get 638.
Grab the next digit (8) from the dividend, add it to 638, then carry on: 6388 / 989

Step 8:
989 can be fit into 6388 6 times, resulting in a remainder of 454.
The number 6 becomes the next digit in our result. 
Result so far: 98606.0
If we subtract 5934 from 6388, we get 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Step 9:
When dividing 4540 by 989, we get 4 with a remainder of 584.
The number 4 becomes the next digit in our result. 
Result so far: 98606.4
Deduct 3956 from 4540 and we're left with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Step 10:
If we divide 5840 by 989, we get 5 and a remainder of 895.
Put 5 as the next digit of the answer. 
Result so far: 98606.45
Deduct 4945 from 5840 and we're left with 895.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8950, and continue the process.

Advancing to step 11:
If we divide 8950 by 989, we get 9 and a remainder of 49.
The number 9 becomes the next digit in our result. 
Result so far: 98606.459
Subtracting 8901 from 8950 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 12:
490 divided by 989 is 0 with a remainder of 490.
Write down 0 as next digit of the result. 
Result so far: 98606.459
Deduct 0 from 490 and we're left with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Moving on to step 13:
989 goes into 4900 4 times with a remainder of 944.
The number 4 becomes the next digit in our result. 
Result so far: 98606.45904
The remainder is 944 after subtracting 3956 from 4900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9440, and continue the process.

Moving on to step 14:
The number 989 fits into 9440 9 times, leaving a remainder of 539.
Record the quotient 9 as the next digit in the result. 
Result so far: 98606.459049
If we take 8901 away from 9440, we end up with 539.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5390, and continue the process.

Going ahead to step 15:
5390 divided by 989 is 5 with a remainder of 445.
The next digit of our result is 5. 
Result so far: 98606.4590495
If we take 4945 away from 5390, we end up with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Step 16:
The number 989 fits into 4450 4 times, leaving a remainder of 494.
Write down 4 as next digit of the result. 
Result so far: 98606.45904954
If we take 3956 away from 4450, we end up with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

After the division, we end up with 98606.45904954 and a remainder of 4.94e-07.
