We look at the division of 62204545 by 21 
Let's see how many times 21 fits into 62204545.

On to step 1:
6 divided by 21 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 21

Going ahead to step 2:
21 goes into 62 2 times with a remainder of 20.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 42 from 62 and we're left with 20.
Take the next digit (2) from the dividend and append it to 20, then repeat: 202 / 21

Step 3:
When dividing 202 by 21, we get 9 with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Subtract 189 from 202 to get 13.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 21

Moving on to step 4:
The number 21 fits into 130 6 times, leaving a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 296.0
If we subtract 126 from 130, we get 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 21

Step 5:
When dividing 44 by 21, we get 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 2962.0
If we subtract 42 from 44, we get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 21

Going ahead to step 6:
21 goes into 25 1 times with a remainder of 4.
The next digit of our result is 1. 
Result so far: 29621.0
If we subtract 21 from 25, we get 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 21

Let's proceed to step 7:
44 divided by 21 is 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 296212.0
If we subtract 42 from 44, we get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 21

Going ahead to step 8:
When dividing 25 by 21, we get 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 2962121.0
Deduct 21 from 25 and we're left 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.

Advancing to step 9:
The number 21 fits into 40 1 times, leaving a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 2962121.1
Subtracting 21 from 40 leaves us 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.

On to step 10:
21 goes into 190 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 2962121.19
Subtract 189 from 190 to get 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 11:
The number 21 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 2962121.19
The remainder is 10 after subtracting 0 from 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 12:
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: 2962121.1904
If we take 84 away from 100, we end up 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.

Moving on to step 13:
160 divided by 21 is 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 2962121.19047
Subtracting 147 from 160 leaves us 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.

On to step 14:
When dividing 130 by 21, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 2962121.190476
The remainder is 4 after subtracting 126 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 15:
When dividing 40 by 21, we get 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 2962121.1904761
Subtracting 21 from 40 leaves us 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.

On to step 16:
21 goes into 190 9 times with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 2962121.19047619
Subtract 189 from 190 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Our division results in 2962121.19047619 with a remaining 1e-09.
