We're dividing 378816 by 28 
Let's see how many times 28 fits into 378816.

Let's proceed to step 1:
3 divided by 28 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 28

Moving on to step 2:
If we divide 37 by 28, we get 1 and a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 28 from 37 leaves us with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 28

Let's proceed to step 3:
The number 28 fits into 98 3 times, leaving a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 13.0
Deduct 84 from 98 and we're left with 14.
Take the next digit (8) from the dividend and append it to 14, then repeat: 148 / 28

Advancing to step 4:
When dividing 148 by 28, we get 5 with a remainder of 8.
The next digit of our result is 5. 
Result so far: 135.0
If we take 140 away from 148, we end up with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 28

Advancing to step 5:
When dividing 81 by 28, we get 2 with a remainder of 25.
Use 2 as the next digit of our solution. 
Result so far: 1352.0
If we subtract 56 from 81, we get 25.
Fetch the next digit (6) from the dividend, attach it to 25 and continue: 256 / 28

Going ahead to step 6:
When dividing 256 by 28, we get 9 with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 13529.0
Subtract 252 from 256 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.

On to step 7:
40 divided by 28 is 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 13529.1
Subtracting 28 from 40 leaves us 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.

Advancing to step 8:
When dividing 120 by 28, we get 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 13529.14
Subtract 112 from 120 to 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 9:
When dividing 80 by 28, we get 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 13529.142
If we take 56 away from 80, we end up 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.

Let's proceed to step 10:
If we divide 240 by 28, we get 8 and a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 13529.1428
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.

Let's proceed to step 11:
The number 28 fits into 160 5 times, leaving a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 13529.14285
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.

On to step 12:
When dividing 200 by 28, we get 7 with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 13529.142857
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.

Going ahead to step 13:
40 divided by 28 is 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 13529.1428571
Subtracting 28 from 40 leaves us 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.

On to step 14:
The number 28 fits into 120 4 times, leaving a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 13529.14285714
Subtracting 112 from 120 leaves us 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.

The final outcome is 13529.14285714, with a leftover of 8e-09.
