Let's divide 13294783 by 21
We want to figure out the number of times 13294783 can be divided by 21.

Advancing to step 1:
21 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 21

Let's proceed to step 2:
If we divide 13 by 21, we get 0 and a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Bring next digit (2) of the dividend behind the 13 and repeat the process: 132 / 21

Moving on to step 3:
21 can be fit into 132 6 times, resulting in a remainder of 6.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 126 from 132, we get 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 21

On to step 4:
69 divided by 21 is 3 with a remainder of 6.
The next digit of our result is 3. 
Result so far: 63.0
Subtract 63 from 69 to get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 21

On to step 5:
When dividing 64 by 21, we get 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 633.0
If we subtract 63 from 64, we get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 21

Step 6:
21 goes into 17 0 times with a remainder of 17.
The next digit of our result is 0. 
Result so far: 6330.0
Subtract 0 from 17 to get 17.
Bring next digit (8) of the dividend behind the 17 and repeat the process: 178 / 21

On to step 7:
The number 21 fits into 178 8 times, leaving a remainder of 10.
The next digit of our result is 8. 
Result so far: 63308.0
Deduct 168 from 178 and we're left with 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 21

Advancing to step 8:
21 can be fit into 103 4 times, resulting in a remainder of 19.
The next digit of our result is 4. 
Result so far: 633084.0
Subtracting 84 from 103 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.

Let's proceed to step 9:
If we divide 190 by 21, we get 9 and a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 633084.9
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 10:
10 divided by 21 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 633084.9
Deduct 0 from 10 and we're left 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.

Moving on to step 11:
21 can be fit into 100 4 times, resulting in a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 633084.904
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.

Going ahead to step 12:
When dividing 160 by 21, we get 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 633084.9047
If we take 147 away from 160, we end up 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 13:
The number 21 fits into 130 6 times, leaving a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 633084.90476
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.

Let's proceed to step 14:
21 goes into 40 1 times with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 633084.904761
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.

Step 15:
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: 633084.9047619
If we subtract 189 from 190, we 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.

Advancing to step 16:
If we divide 10 by 21, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 633084.9047619
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.

Our division results in 633084.9047619 with a remaining 1e-08.
