We're dividing 869 by 19 
We want to divide 869 by 19.

On to step 1:
8 divided by 19 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 19

Moving on to step 2:
19 can be fit into 86 4 times, resulting in a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 10 after subtracting 76 from 86.
Append the next digit (9) from the dividend to 10 and continue with: 109 / 19

On to step 3:
The number 19 fits into 109 5 times, leaving a remainder of 14.
Use 5 as the next digit of our solution. 
Result so far: 45.0
Subtracting 95 from 109 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 4:
19 can be fit into 140 7 times, resulting in a remainder of 7.
The next digit of our result is 7. 
Result so far: 45.7
If we take 133 away from 140, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 5:
When dividing 70 by 19, we get 3 with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 45.73
The remainder is 13 after subtracting 57 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 6:
19 can be fit into 130 6 times, resulting in a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 45.736
Deduct 114 from 130 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.

Moving on to step 7:
If we divide 160 by 19, we get 8 and a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 45.7368
If we subtract 152 from 160, 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.

Let's proceed to step 8:
19 goes into 80 4 times with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 45.73684
The remainder is 4 after subtracting 76 from 80.
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 9:
If we divide 40 by 19, we get 2 and a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 45.736842
Subtract 38 from 40 to get 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 10:
The number 19 fits into 20 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 45.7368421
Subtract 19 from 20 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 11:
The number 19 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 45.7368421
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 45.7368421 with a remainder of 1e-08.
