We're dividing 622495 by 21 
We want to figure out the number of times 622495 can be divided by 21.

Advancing to step 1:
If we divide 6 by 21, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 21

Step 2:
The number 21 fits into 62 2 times, leaving a remainder of 20.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 20 after subtracting 42 from 62.
Fetch the next digit (2) from the dividend, attach it to 20 and continue: 202 / 21

Advancing to step 3:
When dividing 202 by 21, we get 9 with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 29.0
Subtracting 189 from 202 leaves us with 13.
Bring next digit (4) of the dividend behind the 13 and repeat the process: 134 / 21

Moving on to step 4:
134 divided by 21 is 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 296.0
Deduct 126 from 134 and we're left with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 21

Step 5:
21 can be fit into 89 4 times, resulting in a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 2964.0
If we take 84 away from 89, we end up with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 21

Going ahead to step 6:
55 divided by 21 is 2 with a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 29642.0
The remainder is 13 after subtracting 42 from 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
130 divided by 21 is 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 29642.6
If we subtract 126 from 130, we 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.

Step 8:
21 can be fit into 40 1 times, resulting in a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 29642.61
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.

Going ahead to step 9:
21 goes into 190 9 times with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 29642.619
Deduct 189 from 190 and we're left 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.

Moving on to step 10:
21 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 29642.619
If we subtract 0 from 10, we 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.

Step 11:
21 can be fit into 100 4 times, resulting in a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 29642.61904
Subtract 84 from 100 to 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.

Going ahead to step 12:
160 divided by 21 is 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 29642.619047
Deduct 147 from 160 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 13:
If we divide 130 by 21, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 29642.6190476
If we take 126 away from 130, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
When dividing 40 by 21, we get 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 29642.61904761
If we take 21 away from 40, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Our division results in 29642.61904761 with a remaining 1.9e-08.
