991352 divided by 28 
We want to figure out the number of times 991352 can be divided by 28.

Let's proceed to step 1:
9 divided by 28 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 28

Let's proceed to step 2:
If we divide 99 by 28, we get 3 and a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 84 from 99, we get 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 28

On to step 3:
28 goes into 151 5 times with a remainder of 11.
The next digit of our result is 5. 
Result so far: 35.0
The remainder is 11 after subtracting 140 from 151.
Fetch the next digit (3) from the dividend, attach it to 11 and continue: 113 / 28

Moving on to step 4:
28 goes into 113 4 times with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 354.0
Deduct 112 from 113 and we're left with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 28

Advancing to step 5:
If we divide 15 by 28, we get 0 and a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 3540.0
Deduct 0 from 15 and we're left with 15.
Grab the next digit (2) from the dividend, add it to 15, then carry on: 152 / 28

Step 6:
28 goes into 152 5 times with a remainder of 12.
Write down 5 as next digit of the result. 
Result so far: 35405.0
The remainder is 12 after subtracting 140 from 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 7:
If we divide 120 by 28, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 35405.4
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 8:
The number 28 fits into 80 2 times, leaving a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 35405.42
Subtract 56 from 80 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 9:
28 can be fit into 240 8 times, resulting in a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 35405.428
Subtracting 224 from 240 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 10:
When dividing 160 by 28, we get 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 35405.4285
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.

Advancing to step 11:
28 goes into 200 7 times with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 35405.42857
Subtract 196 from 200 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 12:
The number 28 fits into 40 1 times, leaving a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 35405.428571
If we take 28 away from 40, we end up 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.

Going ahead to step 13:
28 goes into 120 4 times with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 35405.4285714
Deduct 112 from 120 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 14:
The number 28 fits into 80 2 times, leaving a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 35405.42857142
If we subtract 56 from 80, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 35405.42857142 and a remainder of 2.4e-08.
