19900 ÷ 47 
Our goal is to divide 19900 by 47.

On to step 1:
The number 47 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 47

Let's proceed to step 2:
The number 47 fits into 19 0 times, leaving a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Include the next digit (9) from the dividend after 19, then repeat: 199 / 47

Moving on to step 3:
If we divide 199 by 47, we get 4 and a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 188 away from 199, we end up with 11.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 47

Step 4:
When dividing 110 by 47, we get 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
The remainder is 16 after subtracting 94 from 110.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 47

Let's proceed to step 5:
47 can be fit into 160 3 times, resulting in a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 423.0
Deduct 141 from 160 and we're left 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.

Advancing to step 6:
47 can be fit into 190 4 times, resulting in a remainder of 2.
The next digit of our result is 4. 
Result so far: 423.4
Subtracting 188 from 190 leaves us 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.

Step 7:
47 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 423.4
If we take 0 away from 20, we end up with 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 8:
The number 47 fits into 200 4 times, leaving a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 423.404
Deduct 188 from 200 and we're left 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.

Let's proceed to step 9:
The number 47 fits into 120 2 times, leaving a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 423.4042
Subtracting 94 from 120 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 10:
If we divide 260 by 47, we get 5 and a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 423.40425
The remainder is 25 after subtracting 235 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 11:
The number 47 fits into 250 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 423.404255
Subtracting 235 from 250 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 423.404255, and the remainder is 1.5e-06.
