16321423 divided by 989 
We want to figure out the number of times 16321423 can be divided by 989.

On to step 1:
989 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 989

Step 2:
989 can be fit into 16 0 times, resulting in a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 989

Moving on to step 3:
989 goes into 163 0 times with a remainder of 163.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 163 and we're left with 163.
Bring next digit (2) of the dividend behind the 163 and repeat the process: 1632 / 989

Let's proceed to step 4:
1632 divided by 989 is 1 with a remainder of 643.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 989 from 1632, we get 643.
Fetch the next digit (1) from the dividend, attach it to 643 and continue: 6431 / 989

Let's proceed to step 5:
6431 divided by 989 is 6 with a remainder of 497.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Deduct 5934 from 6431 and we're left with 497.
Fetch the next digit (4) from the dividend, attach it to 497 and continue: 4974 / 989

Going ahead to step 6:
989 goes into 4974 5 times with a remainder of 29.
Record the quotient 5 as the next digit in the result. 
Result so far: 165.0
If we take 4945 away from 4974, we end up with 29.
Fetch the next digit (2) from the dividend, attach it to 29 and continue: 292 / 989

Let's proceed to step 7:
292 divided by 989 is 0 with a remainder of 292.
The next digit of our result is 0. 
Result so far: 1650.0
If we subtract 0 from 292, we get 292.
Take the next digit (3) from the dividend and append it to 292, then repeat: 2923 / 989

Step 8:
If we divide 2923 by 989, we get 2 and a remainder of 945.
Record the quotient 2 as the next digit in the result. 
Result so far: 16502.0
Deduct 1978 from 2923 and we're left with 945.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9450, and continue the process.

Going ahead to step 9:
989 can be fit into 9450 9 times, resulting in a remainder of 549.
Put 9 as the next digit of the answer. 
Result so far: 16502.9
If we take 8901 away from 9450, we end up with 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

Moving on to step 10:
989 goes into 5490 5 times with a remainder of 545.
The next digit of our result is 5. 
Result so far: 16502.95
Deduct 4945 from 5490 and we're left with 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Let's proceed to step 11:
When dividing 5450 by 989, we get 5 with a remainder of 505.
The number 5 becomes the next digit in our result. 
Result so far: 16502.955
Subtract 4945 from 5450 to get 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Our division results in 16502.955 with a remaining 0.0505.
