Let's divide 107291 by 21
We want to figure out the number of times 107291 can be divided by 21.

Let's proceed to step 1:
When dividing 1 by 21, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 21

On to step 2:
10 divided by 21 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Bring next digit (7) of the dividend behind the 10 and repeat the process: 107 / 21

Let's proceed to step 3:
21 can be fit into 107 5 times, resulting in a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 105 from 107 and we're left with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 21

Going ahead to step 4:
21 can be fit into 22 1 times, resulting in a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 51.0
If we take 21 away from 22, we end up with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 21

Advancing to step 5:
21 can be fit into 19 0 times, resulting in a remainder of 19.
The next digit of our result is 0. 
Result so far: 510.0
Subtracting 0 from 19 leaves us with 19.
Grab the next digit (1) from the dividend, add it to 19, then carry on: 191 / 21

Moving on to step 6:
The number 21 fits into 191 9 times, leaving a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 5109.0
If we subtract 189 from 191, 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.

Let's proceed to step 7:
The number 21 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 5109.0
Deduct 0 from 20 and we're left 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 8:
When dividing 200 by 21, we get 9 with a remainder of 11.
The next digit of our result is 9. 
Result so far: 5109.09
If we take 189 away from 200, we end up with 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 9:
21 can be fit into 110 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 5109.095
Subtract 105 from 110 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 10:
When dividing 50 by 21, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 5109.0952
Deduct 42 from 50 and we're left 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.

Let's proceed to step 11:
The number 21 fits into 80 3 times, leaving a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 5109.09523
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.

Going ahead to step 12:
The number 21 fits into 170 8 times, leaving a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 5109.095238
The remainder is 2 after subtracting 168 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 13:
20 divided by 21 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 5109.095238
If we subtract 0 from 20, we get 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 14:
The number 21 fits into 200 9 times, leaving a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 5109.09523809
Subtracting 189 from 200 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

In conclusion, the division gives 5109.09523809 with a balance of 1.1e-08.
