We look at the division of 19189471 by 489 
We want to divide 19189471 by 489.

Let's proceed to step 1:
489 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 489

Advancing to step 2:
19 divided by 489 is 0 with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Append the next digit (1) from the dividend to 19 and continue with: 191 / 489

Advancing to step 3:
The number 489 fits into 191 0 times, leaving a remainder of 191.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 191 leaves us with 191.
Include the next digit (8) from the dividend after 191, then repeat: 1918 / 489

On to step 4:
If we divide 1918 by 489, we get 3 and a remainder of 451.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 1467 away from 1918, we end up with 451.
Include the next digit (9) from the dividend after 451, then repeat: 4519 / 489

Going ahead to step 5:
The number 489 fits into 4519 9 times, leaving a remainder of 118.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Subtract 4401 from 4519 to get 118.
Grab the next digit (4) from the dividend, add it to 118, then carry on: 1184 / 489

Going ahead to step 6:
If we divide 1184 by 489, we get 2 and a remainder of 206.
The number 2 becomes the next digit in our result. 
Result so far: 392.0
The remainder is 206 after subtracting 978 from 1184.
Take the next digit (7) from the dividend and append it to 206, then repeat: 2067 / 489

Let's proceed to step 7:
489 can be fit into 2067 4 times, resulting in a remainder of 111.
The number 4 becomes the next digit in our result. 
Result so far: 3924.0
If we take 1956 away from 2067, we end up with 111.
Append the next digit (1) from the dividend to 111 and continue with: 1111 / 489

On to step 8:
When dividing 1111 by 489, we get 2 with a remainder of 133.
The number 2 becomes the next digit in our result. 
Result so far: 39242.0
Subtract 978 from 1111 to get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Moving on to step 9:
The number 489 fits into 1330 2 times, leaving a remainder of 352.
Use 2 as the next digit of our solution. 
Result so far: 39242.2
If we subtract 978 from 1330, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Going ahead to step 10:
489 can be fit into 3520 7 times, resulting in a remainder of 97.
The next digit of our result is 7. 
Result so far: 39242.27
The remainder is 97 after subtracting 3423 from 3520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 11:
When dividing 970 by 489, we get 1 with a remainder of 481.
Record the quotient 1 as the next digit in the result. 
Result so far: 39242.271
Subtract 489 from 970 to get 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

On to step 12:
489 goes into 4810 9 times with a remainder of 409.
Record the quotient 9 as the next digit in the result. 
Result so far: 39242.2719
Deduct 4401 from 4810 and we're left with 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Moving on to step 13:
4090 divided by 489 is 8 with a remainder of 178.
Write down 8 as next digit of the result. 
Result so far: 39242.27198
Deduct 3912 from 4090 and we're left with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Going ahead to step 14:
The number 489 fits into 1780 3 times, leaving a remainder of 313.
Put 3 as the next digit of the answer. 
Result so far: 39242.271983
Subtracting 1467 from 1780 leaves us with 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Moving on to step 15:
If we divide 3130 by 489, we get 6 and a remainder of 196.
Put 6 as the next digit of the answer. 
Result so far: 39242.2719836
If we take 2934 away from 3130, we end up with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

On to step 16:
1960 divided by 489 is 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 39242.27198364
If we take 1956 away from 1960, 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.

After the division, we end up with 39242.27198364 and a remainder of 4e-09.
