54827680 ÷ 989 
The aim is to understand the frequency of 989 in 54827680.

Step 1:
989 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 989

Step 2:
The number 989 fits into 54 0 times, leaving a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Include the next digit (8) from the dividend after 54, then repeat: 548 / 989

Let's proceed to step 3:
When dividing 548 by 989, we get 0 with a remainder of 548.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 548, we get 548.
Take the next digit (2) from the dividend and append it to 548, then repeat: 5482 / 989

Step 4:
989 can be fit into 5482 5 times, resulting in a remainder of 537.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 4945 from 5482, we get 537.
Append the next digit (7) from the dividend to 537 and continue with: 5377 / 989

Step 5:
989 can be fit into 5377 5 times, resulting in a remainder of 432.
The next digit of our result is 5. 
Result so far: 55.0
Subtract 4945 from 5377 to get 432.
Bring next digit (6) of the dividend behind the 432 and repeat the process: 4326 / 989

Step 6:
4326 divided by 989 is 4 with a remainder of 370.
Put 4 as the next digit of the answer. 
Result so far: 554.0
Subtract 3956 from 4326 to get 370.
Fetch the next digit (8) from the dividend, attach it to 370 and continue: 3708 / 989

Going ahead to step 7:
989 goes into 3708 3 times with a remainder of 741.
The number 3 becomes the next digit in our result. 
Result so far: 5543.0
Subtract 2967 from 3708 to get 741.
Take the next digit (0) from the dividend and append it to 741, then repeat: 7410 / 989

Step 8:
If we divide 7410 by 989, we get 7 and a remainder of 487.
The next digit of our result is 7. 
Result so far: 55437.0
Subtract 6923 from 7410 to get 487.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4870, and continue the process.

Advancing to step 9:
989 can be fit into 4870 4 times, resulting in a remainder of 914.
Record the quotient 4 as the next digit in the result. 
Result so far: 55437.4
If we subtract 3956 from 4870, we get 914.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9140, and continue the process.

On to step 10:
The number 989 fits into 9140 9 times, leaving a remainder of 239.
The number 9 becomes the next digit in our result. 
Result so far: 55437.49
Deduct 8901 from 9140 and we're left with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Step 11:
The number 989 fits into 2390 2 times, leaving a remainder of 412.
Write down 2 as next digit of the result. 
Result so far: 55437.492
The remainder is 412 after subtracting 1978 from 2390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Moving on to step 12:
4120 divided by 989 is 4 with a remainder of 164.
The number 4 becomes the next digit in our result. 
Result so far: 55437.4924
Deduct 3956 from 4120 and we're left with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

On to step 13:
1640 divided by 989 is 1 with a remainder of 651.
Record the quotient 1 as the next digit in the result. 
Result so far: 55437.49241
If we take 989 away from 1640, we end up with 651.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6510, and continue the process.

Advancing to step 14:
989 can be fit into 6510 6 times, resulting in a remainder of 576.
The number 6 becomes the next digit in our result. 
Result so far: 55437.492416
Deduct 5934 from 6510 and we're left with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Advancing to step 15:
If we divide 5760 by 989, we get 5 and a remainder of 815.
Put 5 as the next digit of the answer. 
Result so far: 55437.4924165
If we take 4945 away from 5760, we end up with 815.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8150, and continue the process.

Moving on to step 16:
When dividing 8150 by 989, we get 8 with a remainder of 238.
Use 8 as the next digit of our solution. 
Result so far: 55437.49241658
Subtract 7912 from 8150 to get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

The quotient of the division is 55437.49241658, and the remainder is 2.38e-07.
