21239356 ÷ 108 
Let's see how many times 108 fits into 21239356.

Going ahead to step 1:
108 goes into 2 0 times 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 / 108

Advancing to step 2:
108 goes into 21 0 times with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Fetch the next digit (2) from the dividend, attach it to 21 and continue: 212 / 108

Going ahead to step 3:
108 can be fit into 212 1 times, resulting in a remainder of 104.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 108 from 212 leaves us with 104.
Take the next digit (3) from the dividend and append it to 104, then repeat: 1043 / 108

On to step 4:
When dividing 1043 by 108, we get 9 with a remainder of 71.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
The remainder is 71 after subtracting 972 from 1043.
Grab the next digit (9) from the dividend, add it to 71, then carry on: 719 / 108

On to step 5:
719 divided by 108 is 6 with a remainder of 71.
The number 6 becomes the next digit in our result. 
Result so far: 196.0
If we subtract 648 from 719, we get 71.
Grab the next digit (3) from the dividend, add it to 71, then carry on: 713 / 108

Step 6:
The number 108 fits into 713 6 times, leaving a remainder of 65.
Use 6 as the next digit of our solution. 
Result so far: 1966.0
If we subtract 648 from 713, we get 65.
Grab the next digit (5) from the dividend, add it to 65, then carry on: 655 / 108

Going ahead to step 7:
108 can be fit into 655 6 times, resulting in a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 19666.0
Deduct 648 from 655 and we're left with 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 108

Going ahead to step 8:
If we divide 76 by 108, we get 0 and a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 196660.0
The remainder is 76 after subtracting 0 from 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 9:
108 can be fit into 760 7 times, resulting in a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 196660.7
The remainder is 4 after subtracting 756 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
108 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 196660.7
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
The number 108 fits into 400 3 times, leaving a remainder of 76.
The number 3 becomes the next digit in our result. 
Result so far: 196660.703
Deduct 324 from 400 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 12:
If we divide 760 by 108, we get 7 and a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 196660.7037
Deduct 756 from 760 and we're left 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.

Step 13:
When dividing 40 by 108, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 196660.7037
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 14:
108 goes into 400 3 times with a remainder of 76.
Use 3 as the next digit of our solution. 
Result so far: 196660.703703
Subtracting 324 from 400 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 15:
760 divided by 108 is 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 196660.7037037
The remainder is 4 after subtracting 756 from 760.
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 16:
108 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 196660.7037037
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 196660.7037037 and a remainder of 4e-08.
