21372968 ÷ 109 
We want to figure out the number of times 21372968 can be divided by 109.

Let's proceed to step 1:
When dividing 2 by 109, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 109

Step 2:
21 divided by 109 is 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Bring next digit (3) of the dividend behind the 21 and repeat the process: 213 / 109

On to step 3:
The number 109 fits into 213 1 times, leaving a remainder of 104.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 104 after subtracting 109 from 213.
Fetch the next digit (7) from the dividend, attach it to 104 and continue: 1047 / 109

Going ahead to step 4:
When dividing 1047 by 109, we get 9 with a remainder of 66.
Write down 9 as next digit of the result. 
Result so far: 19.0
The remainder is 66 after subtracting 981 from 1047.
Bring next digit (2) of the dividend behind the 66 and repeat the process: 662 / 109

Step 5:
When dividing 662 by 109, we get 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 196.0
Subtracting 654 from 662 leaves us with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 109

Moving on to step 6:
109 goes into 89 0 times with a remainder of 89.
The next digit of our result is 0. 
Result so far: 1960.0
If we subtract 0 from 89, we get 89.
Take the next digit (6) from the dividend and append it to 89, then repeat: 896 / 109

Going ahead to step 7:
When dividing 896 by 109, we get 8 with a remainder of 24.
The next digit of our result is 8. 
Result so far: 19608.0
The remainder is 24 after subtracting 872 from 896.
Fetch the next digit (8) from the dividend, attach it to 24 and continue: 248 / 109

Going ahead to step 8:
If we divide 248 by 109, we get 2 and a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 196082.0
If we take 218 away from 248, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
300 divided by 109 is 2 with a remainder of 82.
Use 2 as the next digit of our solution. 
Result so far: 196082.2
If we take 218 away from 300, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 10:
If we divide 820 by 109, we get 7 and a remainder of 57.
Record the quotient 7 as the next digit in the result. 
Result so far: 196082.27
The remainder is 57 after subtracting 763 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 11:
109 can be fit into 570 5 times, resulting in a remainder of 25.
The next digit of our result is 5. 
Result so far: 196082.275
If we subtract 545 from 570, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 12:
250 divided by 109 is 2 with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 196082.2752
Subtracting 218 from 250 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 13:
If we divide 320 by 109, we get 2 and a remainder of 102.
Record the quotient 2 as the next digit in the result. 
Result so far: 196082.27522
Deduct 218 from 320 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

In conclusion, the division gives 196082.27522 with a balance of 0.000102.
