We look at the division of 19935502 by 989 
The aim is to understand the frequency of 989 in 19935502.

Step 1:
989 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 989

On to step 2:
The number 989 fits into 19 0 times, leaving a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Bring next digit (9) of the dividend behind the 19 and repeat the process: 199 / 989

Advancing to step 3:
989 can be fit into 199 0 times, resulting in a remainder of 199.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 199, we end up with 199.
Take the next digit (3) from the dividend and append it to 199, then repeat: 1993 / 989

Moving on to step 4:
If we divide 1993 by 989, we get 2 and a remainder of 15.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 1978 from 1993 and we're left with 15.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 989

Let's proceed to step 5:
When dividing 155 by 989, we get 0 with a remainder of 155.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we subtract 0 from 155, we get 155.
Bring next digit (5) of the dividend behind the 155 and repeat the process: 1555 / 989

Let's proceed to step 6:
989 goes into 1555 1 times with a remainder of 566.
Write down 1 as next digit of the result. 
Result so far: 201.0
The remainder is 566 after subtracting 989 from 1555.
Grab the next digit (0) from the dividend, add it to 566, then carry on: 5660 / 989

On to step 7:
989 can be fit into 5660 5 times, resulting in a remainder of 715.
The next digit of our result is 5. 
Result so far: 2015.0
Subtract 4945 from 5660 to get 715.
Take the next digit (2) from the dividend and append it to 715, then repeat: 7152 / 989

Step 8:
If we divide 7152 by 989, we get 7 and a remainder of 229.
Put 7 as the next digit of the answer. 
Result so far: 20157.0
If we subtract 6923 from 7152, we get 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Moving on to step 9:
989 goes into 2290 2 times with a remainder of 312.
Put 2 as the next digit of the answer. 
Result so far: 20157.2
Subtract 1978 from 2290 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Going ahead to step 10:
When dividing 3120 by 989, we get 3 with a remainder of 153.
Put 3 as the next digit of the answer. 
Result so far: 20157.23
If we take 2967 away from 3120, we end up with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Advancing to step 11:
When dividing 1530 by 989, we get 1 with a remainder of 541.
Write down 1 as next digit of the result. 
Result so far: 20157.231
If we take 989 away from 1530, we end up with 541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5410, and continue the process.

Moving on to step 12:
When dividing 5410 by 989, we get 5 with a remainder of 465.
Write down 5 as next digit of the result. 
Result so far: 20157.2315
If we take 4945 away from 5410, we end up with 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Let's proceed to step 13:
The number 989 fits into 4650 4 times, leaving a remainder of 694.
The next digit of our result is 4. 
Result so far: 20157.23154
The remainder is 694 after subtracting 3956 from 4650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6940, and continue the process.

Step 14:
6940 divided by 989 is 7 with a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 20157.231547
Subtract 6923 from 6940 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 15:
When dividing 170 by 989, we get 0 with a remainder of 170.
Write down 0 as next digit of the result. 
Result so far: 20157.231547
If we subtract 0 from 170, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 16:
The number 989 fits into 1700 1 times, leaving a remainder of 711.
Record the quotient 1 as the next digit in the result. 
Result so far: 20157.23154701
Deduct 989 from 1700 and we're left with 711.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7110, and continue the process.

The final outcome is 20157.23154701, with a leftover of 7.11e-07.
