Let's divide 35803 by 28
We're looking to find how many times 28 goes into 35803.

Going ahead to step 1:
If we divide 3 by 28, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 28

Going ahead to step 2:
If we divide 35 by 28, we get 1 and a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 28 from 35 to get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 28

On to step 3:
When dividing 78 by 28, we get 2 with a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 56 from 78, we get 22.
Grab the next digit (0) from the dividend, add it to 22, then carry on: 220 / 28

On to step 4:
28 can be fit into 220 7 times, resulting in a remainder of 24.
The next digit of our result is 7. 
Result so far: 127.0
The remainder is 24 after subtracting 196 from 220.
Append the next digit (3) from the dividend to 24 and continue with: 243 / 28

Let's proceed to step 5:
243 divided by 28 is 8 with a remainder of 19.
Write down 8 as next digit of the result. 
Result so far: 1278.0
Subtracting 224 from 243 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 6:
If we divide 190 by 28, we get 6 and a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 1278.6
Subtract 168 from 190 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 7:
28 can be fit into 220 7 times, resulting in a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 1278.67
If we subtract 196 from 220, 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 8:
28 goes into 240 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 1278.678
If we take 224 away from 240, we end up 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.

On to step 9:
When dividing 160 by 28, we get 5 with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 1278.6785
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.

Going ahead to step 10:
If we divide 200 by 28, we get 7 and a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 1278.67857
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.

Step 11:
28 can be fit into 40 1 times, resulting in a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1278.678571
If we subtract 28 from 40, we 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.

Advancing to step 12:
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: 1278.6785714
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.

Step 13:
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: 1278.67857142
The remainder is 24 after subtracting 56 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 1278.67857142 with a remainder of 2.4e-08.
