20457775 ÷ 321 
Let's see how many times 321 fits into 20457775.

Moving on to step 1:
321 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 321

Moving on to step 2:
321 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Include the next digit (4) from the dividend after 20, then repeat: 204 / 321

Step 3:
204 divided by 321 is 0 with a remainder of 204.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 204, we end up with 204.
Include the next digit (5) from the dividend after 204, then repeat: 2045 / 321

Moving on to step 4:
321 can be fit into 2045 6 times, resulting in a remainder of 119.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 1926 from 2045 to get 119.
Append the next digit (7) from the dividend to 119 and continue with: 1197 / 321

Step 5:
When dividing 1197 by 321, we get 3 with a remainder of 234.
The next digit of our result is 3. 
Result so far: 63.0
If we take 963 away from 1197, we end up with 234.
Include the next digit (7) from the dividend after 234, then repeat: 2347 / 321

Advancing to step 6:
The number 321 fits into 2347 7 times, leaving a remainder of 100.
Record the quotient 7 as the next digit in the result. 
Result so far: 637.0
Deduct 2247 from 2347 and we're left with 100.
Take the next digit (7) from the dividend and append it to 100, then repeat: 1007 / 321

Step 7:
If we divide 1007 by 321, we get 3 and a remainder of 44.
Put 3 as the next digit of the answer. 
Result so far: 6373.0
If we subtract 963 from 1007, we get 44.
Fetch the next digit (5) from the dividend, attach it to 44 and continue: 445 / 321

Moving on to step 8:
321 can be fit into 445 1 times, resulting in a remainder of 124.
The next digit of our result is 1. 
Result so far: 63731.0
If we subtract 321 from 445, we get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Going ahead to step 9:
The number 321 fits into 1240 3 times, leaving a remainder of 277.
The next digit of our result is 3. 
Result so far: 63731.3
If we subtract 963 from 1240, we get 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Going ahead to step 10:
If we divide 2770 by 321, we get 8 and a remainder of 202.
Put 8 as the next digit of the answer. 
Result so far: 63731.38
If we take 2568 away from 2770, we end up with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

On to step 11:
321 goes into 2020 6 times with a remainder of 94.
Write down 6 as next digit of the result. 
Result so far: 63731.386
Subtract 1926 from 2020 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 12:
When dividing 940 by 321, we get 2 with a remainder of 298.
Put 2 as the next digit of the answer. 
Result so far: 63731.3862
If we subtract 642 from 940, we get 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Moving on to step 13:
The number 321 fits into 2980 9 times, leaving a remainder of 91.
Put 9 as the next digit of the answer. 
Result so far: 63731.38629
Subtracting 2889 from 2980 leaves us with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Advancing to step 14:
321 can be fit into 910 2 times, resulting in a remainder of 268.
Put 2 as the next digit of the answer. 
Result so far: 63731.386292
Subtracting 642 from 910 leaves us with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

On to step 15:
When dividing 2680 by 321, we get 8 with a remainder of 112.
The next digit of our result is 8. 
Result so far: 63731.3862928
If we subtract 2568 from 2680, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 16:
The number 321 fits into 1120 3 times, leaving a remainder of 157.
The number 3 becomes the next digit in our result. 
Result so far: 63731.38629283
The remainder is 157 after subtracting 963 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Our division results in 63731.38629283 with a remaining 1.57e-07.
