Let's divide 436638 by 19
We're looking to find how many times 19 goes into 436638.

On to step 1:
19 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 19

Going ahead to step 2:
19 goes into 43 2 times with a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 38 from 43 leaves us with 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 19

Going ahead to step 3:
The number 19 fits into 56 2 times, leaving a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Deduct 38 from 56 and we're left with 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 19

Moving on to step 4:
186 divided by 19 is 9 with a remainder of 15.
The next digit of our result is 9. 
Result so far: 229.0
The remainder is 15 after subtracting 171 from 186.
Take the next digit (3) from the dividend and append it to 15, then repeat: 153 / 19

Going ahead to step 5:
19 can be fit into 153 8 times, resulting in a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 2298.0
Deduct 152 from 153 and we're left with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 19

Going ahead to step 6:
If we divide 18 by 19, we get 0 and a remainder of 18.
The next digit of our result is 0. 
Result so far: 22980.0
Subtract 0 from 18 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
19 goes into 180 9 times with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 22980.9
If we take 171 away from 180, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 8:
The number 19 fits into 90 4 times, leaving a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 22980.94
Subtract 76 from 90 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 9:
The number 19 fits into 140 7 times, leaving a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 22980.947
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.

Moving on to step 10:
When dividing 70 by 19, we get 3 with a remainder of 13.
The next digit of our result is 3. 
Result so far: 22980.9473
Subtract 57 from 70 to get 13.
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 11:
If we divide 130 by 19, we get 6 and a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 22980.94736
If we take 114 away from 130, 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.

Let's proceed to step 12:
If we divide 160 by 19, we get 8 and a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 22980.947368
Deduct 152 from 160 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 13:
19 can be fit into 80 4 times, resulting in a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 22980.9473684
If we take 76 away from 80, we end up with 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 14:
19 goes into 40 2 times with a remainder of 2.
The next digit of our result is 2. 
Result so far: 22980.94736842
Deduct 38 from 40 and we're left 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.

After the division, we end up with 22980.94736842 and a remainder of 2e-09.
