20653421 ÷ 320 
We're looking to find how many times 320 goes into 20653421.

On to step 1:
The number 320 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 320

On to step 2:
The number 320 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Bring next digit (6) of the dividend behind the 20 and repeat the process: 206 / 320

On to step 3:
320 goes into 206 0 times with a remainder of 206.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 206 leaves us with 206.
Bring next digit (5) of the dividend behind the 206 and repeat the process: 2065 / 320

Step 4:
320 goes into 2065 6 times with a remainder of 145.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 1920 away from 2065, we end up with 145.
Append the next digit (3) from the dividend to 145 and continue with: 1453 / 320

Step 5:
320 can be fit into 1453 4 times, resulting in a remainder of 173.
Put 4 as the next digit of the answer. 
Result so far: 64.0
Deduct 1280 from 1453 and we're left with 173.
Fetch the next digit (4) from the dividend, attach it to 173 and continue: 1734 / 320

Step 6:
320 can be fit into 1734 5 times, resulting in a remainder of 134.
The next digit of our result is 5. 
Result so far: 645.0
Subtracting 1600 from 1734 leaves us with 134.
Grab the next digit (2) from the dividend, add it to 134, then carry on: 1342 / 320

On to step 7:
When dividing 1342 by 320, we get 4 with a remainder of 62.
Put 4 as the next digit of the answer. 
Result so far: 6454.0
If we take 1280 away from 1342, we end up with 62.
Take the next digit (1) from the dividend and append it to 62, then repeat: 621 / 320

Moving on to step 8:
320 goes into 621 1 times with a remainder of 301.
Record the quotient 1 as the next digit in the result. 
Result so far: 64541.0
The remainder is 301 after subtracting 320 from 621.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

On to step 9:
3010 divided by 320 is 9 with a remainder of 130.
The number 9 becomes the next digit in our result. 
Result so far: 64541.9
The remainder is 130 after subtracting 2880 from 3010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 10:
1300 divided by 320 is 4 with a remainder of 20.
The next digit of our result is 4. 
Result so far: 64541.94
Subtract 1280 from 1300 to get 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 11:
320 can be fit into 200 0 times, resulting in a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 64541.94
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 12:
The number 320 fits into 2000 6 times, leaving a remainder of 80.
Put 6 as the next digit of the answer. 
Result so far: 64541.9406
Deduct 1920 from 2000 and we're left 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 13:
800 divided by 320 is 2 with a remainder of 160.
Use 2 as the next digit of our solution. 
Result so far: 64541.94062
The remainder is 160 after subtracting 640 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 14:
320 can be fit into 1600 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 64541.940625
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.

Moving on to step 15:
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: 64541.940625
Subtracting 0 from 0 leaves us 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.

Let's proceed to step 16:
320 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 64541.940625
If we take 0 away from 0, we end up 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 64541.940625 with a remaining 0.0.
