21655921 divided by 486 
Our goal is to divide 21655921 by 486.

Going ahead to step 1:
The number 486 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 486

Going ahead to step 2:
486 goes into 21 0 times with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 486

Step 3:
The number 486 fits into 216 0 times, leaving a remainder of 216.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 216 and we're left with 216.
Take the next digit (5) from the dividend and append it to 216, then repeat: 2165 / 486

Let's proceed to step 4:
The number 486 fits into 2165 4 times, leaving a remainder of 221.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 1944 from 2165, we get 221.
Append the next digit (5) from the dividend to 221 and continue with: 2215 / 486

Advancing to step 5:
486 goes into 2215 4 times with a remainder of 271.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
The remainder is 271 after subtracting 1944 from 2215.
Include the next digit (9) from the dividend after 271, then repeat: 2719 / 486

Advancing to step 6:
2719 divided by 486 is 5 with a remainder of 289.
The number 5 becomes the next digit in our result. 
Result so far: 445.0
Deduct 2430 from 2719 and we're left with 289.
Bring next digit (2) of the dividend behind the 289 and repeat the process: 2892 / 486

Let's proceed to step 7:
The number 486 fits into 2892 5 times, leaving a remainder of 462.
The next digit of our result is 5. 
Result so far: 4455.0
Subtract 2430 from 2892 to get 462.
Include the next digit (1) from the dividend after 462, then repeat: 4621 / 486

Going ahead to step 8:
When dividing 4621 by 486, we get 9 with a remainder of 247.
Put 9 as the next digit of the answer. 
Result so far: 44559.0
Subtract 4374 from 4621 to get 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Going ahead to step 9:
If we divide 2470 by 486, we get 5 and a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 44559.5
Subtracting 2430 from 2470 leaves us 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.

Let's proceed to step 10:
486 goes into 400 0 times with a remainder of 400.
The next digit of our result is 0. 
Result so far: 44559.5
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 11:
The number 486 fits into 4000 8 times, leaving a remainder of 112.
Record the quotient 8 as the next digit in the result. 
Result so far: 44559.508
The remainder is 112 after subtracting 3888 from 4000.
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 12:
486 can be fit into 1120 2 times, resulting in a remainder of 148.
Put 2 as the next digit of the answer. 
Result so far: 44559.5082
Deduct 972 from 1120 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 13:
When dividing 1480 by 486, we get 3 with a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 44559.50823
If we take 1458 away from 1480, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 14:
If we divide 220 by 486, we get 0 and a remainder of 220.
The next digit of our result is 0. 
Result so far: 44559.50823
Deduct 0 from 220 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 15:
If we divide 2200 by 486, we get 4 and a remainder of 256.
Write down 4 as next digit of the result. 
Result so far: 44559.5082304
If we subtract 1944 from 2200, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 16:
486 can be fit into 2560 5 times, resulting in a remainder of 130.
Use 5 as the next digit of our solution. 
Result so far: 44559.50823045
If we take 2430 away from 2560, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Our division results in 44559.50823045 with a remaining 1.3e-07.
