20508438 ÷ 868 
We want to figure out the number of times 20508438 can be divided by 868.

Step 1:
When dividing 2 by 868, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 868

Let's proceed to step 2:
If we divide 20 by 868, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Fetch the next digit (5) from the dividend, attach it to 20 and continue: 205 / 868

On to step 3:
205 divided by 868 is 0 with a remainder of 205.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 205, we get 205.
Take the next digit (0) from the dividend and append it to 205, then repeat: 2050 / 868

Step 4:
When dividing 2050 by 868, we get 2 with a remainder of 314.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 1736 from 2050, we get 314.
Append the next digit (8) from the dividend to 314 and continue with: 3148 / 868

Step 5:
The number 868 fits into 3148 3 times, leaving a remainder of 544.
Write down 3 as next digit of the result. 
Result so far: 23.0
Deduct 2604 from 3148 and we're left with 544.
Take the next digit (4) from the dividend and append it to 544, then repeat: 5444 / 868

On to step 6:
The number 868 fits into 5444 6 times, leaving a remainder of 236.
Write down 6 as next digit of the result. 
Result so far: 236.0
Deduct 5208 from 5444 and we're left with 236.
Append the next digit (3) from the dividend to 236 and continue with: 2363 / 868

On to step 7:
868 goes into 2363 2 times with a remainder of 627.
Write down 2 as next digit of the result. 
Result so far: 2362.0
Subtract 1736 from 2363 to get 627.
Include the next digit (8) from the dividend after 627, then repeat: 6278 / 868

Let's proceed to step 8:
The number 868 fits into 6278 7 times, leaving a remainder of 202.
The number 7 becomes the next digit in our result. 
Result so far: 23627.0
If we take 6076 away from 6278, we end up with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Let's proceed to step 9:
2020 divided by 868 is 2 with a remainder of 284.
The number 2 becomes the next digit in our result. 
Result so far: 23627.2
Subtract 1736 from 2020 to get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Going ahead to step 10:
868 goes into 2840 3 times with a remainder of 236.
The number 3 becomes the next digit in our result. 
Result so far: 23627.23
Subtract 2604 from 2840 to get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Going ahead to step 11:
868 goes into 2360 2 times with a remainder of 624.
The number 2 becomes the next digit in our result. 
Result so far: 23627.232
Subtract 1736 from 2360 to get 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Going ahead to step 12:
When dividing 6240 by 868, we get 7 with a remainder of 164.
Put 7 as the next digit of the answer. 
Result so far: 23627.2327
Deduct 6076 from 6240 and we're left with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Step 13:
868 can be fit into 1640 1 times, resulting in a remainder of 772.
Use 1 as the next digit of our solution. 
Result so far: 23627.23271
Subtract 868 from 1640 to get 772.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7720, and continue the process.

Advancing to step 14:
868 can be fit into 7720 8 times, resulting in a remainder of 776.
Put 8 as the next digit of the answer. 
Result so far: 23627.232718
If we subtract 6944 from 7720, we get 776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7760, and continue the process.

Advancing to step 15:
7760 divided by 868 is 8 with a remainder of 816.
Use 8 as the next digit of our solution. 
Result so far: 23627.2327188
The remainder is 816 after subtracting 6944 from 7760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8160, and continue the process.

In conclusion, the division gives 23627.2327188 with a balance of 8.16e-06.
