We're dividing 80168897 by 989 
The aim is to understand the frequency of 989 in 80168897.

On to step 1:
8 divided by 989 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 989

Moving on to step 2:
When dividing 80 by 989, we get 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Fetch the next digit (1) from the dividend, attach it to 80 and continue: 801 / 989

On to step 3:
If we divide 801 by 989, we get 0 and a remainder of 801.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 801, we end up with 801.
Grab the next digit (6) from the dividend, add it to 801, then carry on: 8016 / 989

Let's proceed to step 4:
If we divide 8016 by 989, we get 8 and a remainder of 104.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 7912 from 8016 and we're left with 104.
Append the next digit (8) from the dividend to 104 and continue with: 1048 / 989

Moving on to step 5:
989 can be fit into 1048 1 times, resulting in a remainder of 59.
Put 1 as the next digit of the answer. 
Result so far: 81.0
The remainder is 59 after subtracting 989 from 1048.
Append the next digit (8) from the dividend to 59 and continue with: 598 / 989

Step 6:
989 can be fit into 598 0 times, resulting in a remainder of 598.
Write down 0 as next digit of the result. 
Result so far: 810.0
Subtracting 0 from 598 leaves us with 598.
Append the next digit (9) from the dividend to 598 and continue with: 5989 / 989

On to step 7:
When dividing 5989 by 989, we get 6 with a remainder of 55.
Record the quotient 6 as the next digit in the result. 
Result so far: 8106.0
The remainder is 55 after subtracting 5934 from 5989.
Bring next digit (7) of the dividend behind the 55 and repeat the process: 557 / 989

Step 8:
When dividing 557 by 989, we get 0 with a remainder of 557.
Write down 0 as next digit of the result. 
Result so far: 81060.0
The remainder is 557 after subtracting 0 from 557.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5570, and continue the process.

Moving on to step 9:
If we divide 5570 by 989, we get 5 and a remainder of 625.
Write down 5 as next digit of the result. 
Result so far: 81060.5
Subtracting 4945 from 5570 leaves us with 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Going ahead to step 10:
When dividing 6250 by 989, we get 6 with a remainder of 316.
The next digit of our result is 6. 
Result so far: 81060.56
The remainder is 316 after subtracting 5934 from 6250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Step 11:
989 goes into 3160 3 times with a remainder of 193.
Put 3 as the next digit of the answer. 
Result so far: 81060.563
If we subtract 2967 from 3160, we get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Moving on to step 12:
1930 divided by 989 is 1 with a remainder of 941.
Put 1 as the next digit of the answer. 
Result so far: 81060.5631
Subtract 989 from 1930 to get 941.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9410, and continue the process.

Advancing to step 13:
989 goes into 9410 9 times with a remainder of 509.
Write down 9 as next digit of the result. 
Result so far: 81060.56319
Subtracting 8901 from 9410 leaves us with 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

Step 14:
If we divide 5090 by 989, we get 5 and a remainder of 145.
The next digit of our result is 5. 
Result so far: 81060.563195
If we take 4945 away from 5090, we end up with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Step 15:
When dividing 1450 by 989, we get 1 with a remainder of 461.
Write down 1 as next digit of the result. 
Result so far: 81060.5631951
Subtracting 989 from 1450 leaves us with 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

Advancing to step 16:
989 can be fit into 4610 4 times, resulting in a remainder of 654.
The next digit of our result is 4. 
Result so far: 81060.56319514
Subtracting 3956 from 4610 leaves us with 654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Our division results in 81060.56319514 with a remaining 6.54e-07.
