We look at the division of 112199 by 28 
We want to figure out the number of times 112199 can be divided by 28.

Step 1:
28 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 28

On to step 2:
11 divided by 28 is 0 with a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 11, we end up with 11.
Bring next digit (2) of the dividend behind the 11 and repeat the process: 112 / 28

Moving on to step 3:
28 can be fit into 112 4 times, resulting in a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 0 after subtracting 112 from 112.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 28

Going ahead to step 4:
If we divide 1 by 28, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 40.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 28

Step 5:
When dividing 19 by 28, we get 0 with a remainder of 19.
The next digit of our result is 0. 
Result so far: 400.0
Deduct 0 from 19 and we're left with 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 28

Let's proceed to step 6:
28 goes into 199 7 times with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 4007.0
The remainder is 3 after subtracting 196 from 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
30 divided by 28 is 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 4007.1
If we take 28 away from 30, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
When dividing 20 by 28, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 4007.1
If we subtract 0 from 20, 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.

On to step 9:
28 goes into 200 7 times with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 4007.107
If we subtract 196 from 200, we 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.

On to step 10:
28 goes into 40 1 times with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 4007.1071
Subtract 28 from 40 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 11:
28 can be fit into 120 4 times, resulting in a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 4007.10714
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.

Advancing to step 12:
If we divide 80 by 28, we get 2 and a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 4007.107142
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.

Step 13:
28 can be fit into 240 8 times, resulting in a remainder of 16.
The next digit of our result is 8. 
Result so far: 4007.1071428
Deduct 224 from 240 and we're left 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.

Advancing to step 14:
28 can be fit into 160 5 times, resulting in a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 4007.10714285
Subtract 140 from 160 to 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.

The final result is 4007.10714285 with a remainder of 2e-08.
