991958 ÷ 28 
Let's see how many times 28 fits into 991958.

Advancing to step 1:
If we divide 9 by 28, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 28

Let's proceed to step 2:
28 can be fit into 99 3 times, resulting in a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 84 from 99 leaves us with 15.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 28

Step 3:
28 goes into 151 5 times with a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
If we subtract 140 from 151, we get 11.
Fetch the next digit (9) from the dividend, attach it to 11 and continue: 119 / 28

Advancing to step 4:
When dividing 119 by 28, we get 4 with a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 354.0
Subtracting 112 from 119 leaves us with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 28

Going ahead to step 5:
28 goes into 75 2 times with a remainder of 19.
Use 2 as the next digit of our solution. 
Result so far: 3542.0
Deduct 56 from 75 and we're left with 19.
Include the next digit (8) from the dividend after 19, then repeat: 198 / 28

Going ahead to step 6:
198 divided by 28 is 7 with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 35427.0
The remainder is 2 after subtracting 196 from 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
The number 28 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 35427.0
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
If we divide 200 by 28, we get 7 and a remainder of 4.
The next digit of our result is 7. 
Result so far: 35427.07
If we take 196 away from 200, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
When dividing 40 by 28, we get 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 35427.071
Deduct 28 from 40 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
28 goes into 120 4 times with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 35427.0714
If we subtract 112 from 120, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
28 can be fit into 80 2 times, resulting in a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 35427.07142
Deduct 56 from 80 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 12:
28 goes into 240 8 times with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 35427.071428
If we subtract 224 from 240, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
28 goes into 160 5 times with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 35427.0714285
If we subtract 140 from 160, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 14:
The number 28 fits into 200 7 times, leaving a remainder of 4.
The next digit of our result is 7. 
Result so far: 35427.07142857
If we take 196 away from 200, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 35427.07142857 and a remainder of 4e-09.
