1721072 ÷ 384 
We're looking to find how many times 384 goes into 1721072.

Advancing to step 1:
384 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 384

On to step 2:
When dividing 17 by 384, we get 0 with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 384

Moving on to step 3:
The number 384 fits into 172 0 times, leaving a remainder of 172.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 172 leaves us with 172.
Take the next digit (1) from the dividend and append it to 172, then repeat: 1721 / 384

Going ahead to step 4:
The number 384 fits into 1721 4 times, leaving a remainder of 185.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 1536 away from 1721, we end up with 185.
Append the next digit (0) from the dividend to 185 and continue with: 1850 / 384

Let's proceed to step 5:
If we divide 1850 by 384, we get 4 and a remainder of 314.
Use 4 as the next digit of our solution. 
Result so far: 44.0
Deduct 1536 from 1850 and we're left with 314.
Include the next digit (7) from the dividend after 314, then repeat: 3147 / 384

Going ahead to step 6:
If we divide 3147 by 384, we get 8 and a remainder of 75.
The next digit of our result is 8. 
Result so far: 448.0
Subtract 3072 from 3147 to get 75.
Grab the next digit (2) from the dividend, add it to 75, then carry on: 752 / 384

Step 7:
If we divide 752 by 384, we get 1 and a remainder of 368.
Use 1 as the next digit of our solution. 
Result so far: 4481.0
Deduct 384 from 752 and we're left with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Let's proceed to step 8:
384 can be fit into 3680 9 times, resulting in a remainder of 224.
Write down 9 as next digit of the result. 
Result so far: 4481.9
The remainder is 224 after subtracting 3456 from 3680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Let's proceed to step 9:
384 goes into 2240 5 times with a remainder of 320.
Put 5 as the next digit of the answer. 
Result so far: 4481.95
The remainder is 320 after subtracting 1920 from 2240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 10:
The number 384 fits into 3200 8 times, leaving a remainder of 128.
Put 8 as the next digit of the answer. 
Result so far: 4481.958
If we take 3072 away from 3200, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 11:
If we divide 1280 by 384, we get 3 and a remainder of 128.
Use 3 as the next digit of our solution. 
Result so far: 4481.9583
The remainder is 128 after subtracting 1152 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 12:
384 can be fit into 1280 3 times, resulting in a remainder of 128.
Write down 3 as next digit of the result. 
Result so far: 4481.95833
If we take 1152 away from 1280, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The quotient of the division is 4481.95833, and the remainder is 0.000128.
