21380746 divided by 320 
Let's see how many times 320 fits into 21380746.

Let's proceed to step 1:
320 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 320

Moving on to step 2:
21 divided by 320 is 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 320

On to step 3:
320 can be fit into 213 0 times, resulting in a remainder of 213.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 213, we end up with 213.
Take the next digit (8) from the dividend and append it to 213, then repeat: 2138 / 320

Advancing to step 4:
If we divide 2138 by 320, we get 6 and a remainder of 218.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 1920 from 2138 and we're left with 218.
Take the next digit (0) from the dividend and append it to 218, then repeat: 2180 / 320

Step 5:
2180 divided by 320 is 6 with a remainder of 260.
Use 6 as the next digit of our solution. 
Result so far: 66.0
If we take 1920 away from 2180, we end up with 260.
Append the next digit (7) from the dividend to 260 and continue with: 2607 / 320

Step 6:
The number 320 fits into 2607 8 times, leaving a remainder of 47.
The next digit of our result is 8. 
Result so far: 668.0
Subtract 2560 from 2607 to get 47.
Fetch the next digit (4) from the dividend, attach it to 47 and continue: 474 / 320

Step 7:
When dividing 474 by 320, we get 1 with a remainder of 154.
Record the quotient 1 as the next digit in the result. 
Result so far: 6681.0
Deduct 320 from 474 and we're left with 154.
Take the next digit (6) from the dividend and append it to 154, then repeat: 1546 / 320

Moving on to step 8:
320 can be fit into 1546 4 times, resulting in a remainder of 266.
Use 4 as the next digit of our solution. 
Result so far: 66814.0
The remainder is 266 after subtracting 1280 from 1546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Step 9:
If we divide 2660 by 320, we get 8 and a remainder of 100.
The number 8 becomes the next digit in our result. 
Result so far: 66814.8
Subtract 2560 from 2660 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 10:
1000 divided by 320 is 3 with a remainder of 40.
Use 3 as the next digit of our solution. 
Result so far: 66814.83
Deduct 960 from 1000 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
320 goes into 400 1 times with a remainder of 80.
The next digit of our result is 1. 
Result so far: 66814.831
Subtracting 320 from 400 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 12:
320 goes into 800 2 times with a remainder of 160.
Put 2 as the next digit of the answer. 
Result so far: 66814.8312
If we take 640 away from 800, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 13:
If we divide 1600 by 320, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 66814.83125
Deduct 1600 from 1600 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 14:
The number 320 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 66814.83125
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 15:
When dividing 0 by 320, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 66814.83125
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 66814.83125 with a remaining 0.0.
