We're dividing 144221 by 991 
We're looking to find how many times 991 goes into 144221.

Let's proceed to step 1:
991 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
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 991

Moving on to step 2:
991 can be fit into 14 0 times, resulting in a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Include the next digit (4) from the dividend after 14, then repeat: 144 / 991

Advancing to step 3:
991 goes into 144 0 times with a remainder of 144.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 144 leaves us with 144.
Fetch the next digit (2) from the dividend, attach it to 144 and continue: 1442 / 991

Step 4:
991 goes into 1442 1 times with a remainder of 451.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 991 from 1442 to get 451.
Include the next digit (2) from the dividend after 451, then repeat: 4512 / 991

Advancing to step 5:
991 goes into 4512 4 times with a remainder of 548.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Deduct 3964 from 4512 and we're left with 548.
Include the next digit (1) from the dividend after 548, then repeat: 5481 / 991

Going ahead to step 6:
The number 991 fits into 5481 5 times, leaving a remainder of 526.
Use 5 as the next digit of our solution. 
Result so far: 145.0
The remainder is 526 after subtracting 4955 from 5481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Moving on to step 7:
991 goes into 5260 5 times with a remainder of 305.
Write down 5 as next digit of the result. 
Result so far: 145.5
If we take 4955 away from 5260, we end up with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Let's proceed to step 8:
When dividing 3050 by 991, we get 3 with a remainder of 77.
The next digit of our result is 3. 
Result so far: 145.53
Subtracting 2973 from 3050 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 9:
The number 991 fits into 770 0 times, leaving a remainder of 770.
Write down 0 as next digit of the result. 
Result so far: 145.53
If we take 0 away from 770, we end up with 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Let's proceed to step 10:
The number 991 fits into 7700 7 times, leaving a remainder of 763.
The next digit of our result is 7. 
Result so far: 145.5307
Deduct 6937 from 7700 and we're left with 763.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7630, and continue the process.

Going ahead to step 11:
If we divide 7630 by 991, we get 7 and a remainder of 693.
The next digit of our result is 7. 
Result so far: 145.53077
Subtract 6937 from 7630 to get 693.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6930, and continue the process.

In conclusion, the division gives 145.53077 with a balance of 0.000693.
