We look at the division of 62899027 by 21 
Let's see how many times 21 fits into 62899027.

Moving on to step 1:
21 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 21

Going ahead to step 2:
The number 21 fits into 62 2 times, leaving a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 20 after subtracting 42 from 62.
Take the next digit (8) from the dividend and append it to 20, then repeat: 208 / 21

Let's proceed to step 3:
21 can be fit into 208 9 times, resulting in a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
The remainder is 19 after subtracting 189 from 208.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 21

Let's proceed to step 4:
199 divided by 21 is 9 with a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 299.0
The remainder is 10 after subtracting 189 from 199.
Fetch the next digit (9) from the dividend, attach it to 10 and continue: 109 / 21

On to step 5:
21 can be fit into 109 5 times, resulting in a remainder of 4.
The next digit of our result is 5. 
Result so far: 2995.0
Subtracting 105 from 109 leaves us with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 21

Going ahead to step 6:
When dividing 40 by 21, we get 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 29951.0
The remainder is 19 after subtracting 21 from 40.
Append the next digit (2) from the dividend to 19 and continue with: 192 / 21

Going ahead to step 7:
If we divide 192 by 21, we get 9 and a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 299519.0
Subtract 189 from 192 to get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 21

On to step 8:
When dividing 37 by 21, we get 1 with a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 2995191.0
If we take 21 away from 37, 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.

Step 9:
160 divided by 21 is 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 2995191.7
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.

Advancing to step 10:
The number 21 fits into 130 6 times, leaving a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 2995191.76
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.

Moving on to step 11:
40 divided by 21 is 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 2995191.761
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.

Going ahead to step 12:
When dividing 190 by 21, we get 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 2995191.7619
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.

Step 13:
When dividing 10 by 21, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 2995191.7619
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:
21 goes into 100 4 times with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 2995191.761904
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 15:
The number 21 fits into 160 7 times, leaving a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 2995191.7619047
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.

Step 16:
21 can be fit into 130 6 times, resulting in a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 2995191.76190476
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.

The final outcome is 2995191.76190476, with a leftover of 4e-09.
