20856039 ÷ 108 
We want to divide 20856039 by 108.

Step 1:
When dividing 2 by 108, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 108

Let's proceed to step 2:
108 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Take the next digit (8) from the dividend and append it to 20, then repeat: 208 / 108

Going ahead to step 3:
The number 108 fits into 208 1 times, leaving a remainder of 100.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 108 from 208 leaves us with 100.
Fetch the next digit (5) from the dividend, attach it to 100 and continue: 1005 / 108

Let's proceed to step 4:
When dividing 1005 by 108, we get 9 with a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we subtract 972 from 1005, we get 33.
Grab the next digit (6) from the dividend, add it to 33, then carry on: 336 / 108

Going ahead to step 5:
When dividing 336 by 108, we get 3 with a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 193.0
The remainder is 12 after subtracting 324 from 336.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 108

Moving on to step 6:
When dividing 120 by 108, we get 1 with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1931.0
If we subtract 108 from 120, we get 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 108

Step 7:
The number 108 fits into 123 1 times, leaving a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 19311.0
If we subtract 108 from 123, we get 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 108

Let's proceed to step 8:
108 goes into 159 1 times with a remainder of 51.
The number 1 becomes the next digit in our result. 
Result so far: 193111.0
Deduct 108 from 159 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 9:
510 divided by 108 is 4 with a remainder of 78.
Write down 4 as next digit of the result. 
Result so far: 193111.4
The remainder is 78 after subtracting 432 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 10:
780 divided by 108 is 7 with a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 193111.47
The remainder is 24 after subtracting 756 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
240 divided by 108 is 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 193111.472
The remainder is 24 after subtracting 216 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 12:
If we divide 240 by 108, we get 2 and a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 193111.4722
Deduct 216 from 240 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 193111.4722, with a leftover of 0.00024.
