Let's divide 416053 by 21
We want to divide 416053 by 21.

Advancing to step 1:
The number 21 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 21

Going ahead to step 2:
21 goes into 41 1 times with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 21 from 41 to get 20.
Append the next digit (6) from the dividend to 20 and continue with: 206 / 21

Advancing to step 3:
206 divided by 21 is 9 with a remainder of 17.
The next digit of our result is 9. 
Result so far: 19.0
The remainder is 17 after subtracting 189 from 206.
Bring next digit (0) of the dividend behind the 17 and repeat the process: 170 / 21

Moving on to step 4:
When dividing 170 by 21, we get 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 198.0
Deduct 168 from 170 and we're left with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 21

Step 5:
21 can be fit into 25 1 times, resulting in a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1981.0
If we take 21 away from 25, we end up with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 21

Advancing to step 6:
21 can be fit into 43 2 times, resulting in a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 19812.0
If we take 42 away from 43, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
10 divided by 21 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 19812.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
100 divided by 21 is 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 19812.04
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
160 divided by 21 is 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 19812.047
Subtract 147 from 160 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 10:
21 can be fit into 130 6 times, resulting in a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 19812.0476
Subtract 126 from 130 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 11:
When dividing 40 by 21, we get 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 19812.04761
Subtract 21 from 40 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 12:
190 divided by 21 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 19812.047619
The remainder is 1 after subtracting 189 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 13:
21 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 19812.047619
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
The number 21 fits into 100 4 times, leaving a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 19812.04761904
Deduct 84 from 100 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 19812.04761904 and a remainder of 1.6e-08.
