108967 divided by 21 
We're looking to find how many times 21 goes into 108967.

Let's proceed to step 1:
21 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 21

Step 2:
When dividing 10 by 21, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 21

Advancing to step 3:
21 can be fit into 108 5 times, resulting in a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 105 from 108 to get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 21

Going ahead to step 4:
39 divided by 21 is 1 with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
If we take 21 away from 39, we end up with 18.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 21

Step 5:
The number 21 fits into 186 8 times, leaving a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 518.0
Subtract 168 from 186 to get 18.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 21

Going ahead to step 6:
187 divided by 21 is 8 with a remainder of 19.
Record the quotient 8 as the next digit in the result. 
Result so far: 5188.0
The remainder is 19 after subtracting 168 from 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
21 goes into 190 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 5188.9
Subtracting 189 from 190 leaves us 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.

Let's proceed to step 8:
When dividing 10 by 21, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 5188.9
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.

Going ahead to step 9:
If we divide 100 by 21, we get 4 and a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 5188.904
Subtract 84 from 100 to 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.

Step 10:
The number 21 fits into 160 7 times, leaving a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 5188.9047
The remainder is 13 after subtracting 147 from 160.
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 11:
If we divide 130 by 21, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 5188.90476
Subtracting 126 from 130 leaves us 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.

On to step 12:
When dividing 40 by 21, we get 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 5188.904761
If we take 21 away from 40, we end up 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 13:
190 divided by 21 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 5188.9047619
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.

Going ahead to step 14:
21 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 5188.9047619
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.

The final outcome is 5188.9047619, with a leftover of 1e-08.
