We divide 62478515 by 21
Let's see how many times 21 fits into 62478515.

Let's proceed to step 1:
If we divide 6 by 21, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 21

Moving on to step 2:
21 can be fit into 62 2 times, resulting in a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 42 from 62, we get 20.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 21

On to step 3:
204 divided by 21 is 9 with a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
If we take 189 away from 204, we end up with 15.
Include the next digit (7) from the dividend after 15, then repeat: 157 / 21

Going ahead to step 4:
If we divide 157 by 21, we get 7 and a remainder of 10.
The next digit of our result is 7. 
Result so far: 297.0
If we take 147 away from 157, we end up with 10.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 21

Let's proceed to step 5:
21 goes into 108 5 times with a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 2975.0
Subtract 105 from 108 to get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 21

Going ahead to step 6:
The number 21 fits into 35 1 times, leaving a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 29751.0
Subtracting 21 from 35 leaves us with 14.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 21

Step 7:
21 goes into 141 6 times with a remainder of 15.
The number 6 becomes the next digit in our result. 
Result so far: 297516.0
Deduct 126 from 141 and we're left with 15.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 21

Going ahead to step 8:
21 goes into 155 7 times with a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 2975167.0
The remainder is 8 after subtracting 147 from 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
80 divided by 21 is 3 with a remainder of 17.
The next digit of our result is 3. 
Result so far: 2975167.3
If we take 63 away from 80, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 10:
The number 21 fits into 170 8 times, leaving a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 2975167.38
If we take 168 away from 170, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 11:
21 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 2975167.38
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 12:
21 can be fit into 200 9 times, resulting in a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 2975167.3809
Subtract 189 from 200 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 13:
21 can be fit into 110 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 2975167.38095
If we take 105 away from 110, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 14:
If we divide 50 by 21, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 2975167.380952
Subtracting 42 from 50 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 15:
The number 21 fits into 80 3 times, leaving a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 2975167.3809523
The remainder is 17 after subtracting 63 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 16:
When dividing 170 by 21, we get 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 2975167.38095238
If we subtract 168 from 170, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 2975167.38095238 with a remaining 2e-09.
