Let's divide 20486869 by 315
We want to figure out the number of times 20486869 can be divided by 315.

Going ahead to step 1:
2 divided by 315 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 315

On to step 2:
315 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Take the next digit (4) from the dividend and append it to 20, then repeat: 204 / 315

Advancing to step 3:
If we divide 204 by 315, we get 0 and a remainder of 204.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 204 leaves us with 204.
Include the next digit (8) from the dividend after 204, then repeat: 2048 / 315

Moving on to step 4:
315 goes into 2048 6 times with a remainder of 158.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 1890 from 2048 to get 158.
Grab the next digit (6) from the dividend, add it to 158, then carry on: 1586 / 315

On to step 5:
The number 315 fits into 1586 5 times, leaving a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 65.0
Subtracting 1575 from 1586 leaves us with 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 315

Let's proceed to step 6:
315 can be fit into 118 0 times, resulting in a remainder of 118.
The number 0 becomes the next digit in our result. 
Result so far: 650.0
If we subtract 0 from 118, we get 118.
Fetch the next digit (6) from the dividend, attach it to 118 and continue: 1186 / 315

Let's proceed to step 7:
If we divide 1186 by 315, we get 3 and a remainder of 241.
The next digit of our result is 3. 
Result so far: 6503.0
The remainder is 241 after subtracting 945 from 1186.
Include the next digit (9) from the dividend after 241, then repeat: 2419 / 315

Step 8:
When dividing 2419 by 315, we get 7 with a remainder of 214.
The number 7 becomes the next digit in our result. 
Result so far: 65037.0
Deduct 2205 from 2419 and we're left with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Let's proceed to step 9:
315 goes into 2140 6 times with a remainder of 250.
The next digit of our result is 6. 
Result so far: 65037.6
If we subtract 1890 from 2140, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 10:
If we divide 2500 by 315, we get 7 and a remainder of 295.
Record the quotient 7 as the next digit in the result. 
Result so far: 65037.67
Subtracting 2205 from 2500 leaves us with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Let's proceed to step 11:
2950 divided by 315 is 9 with a remainder of 115.
Use 9 as the next digit of our solution. 
Result so far: 65037.679
Subtract 2835 from 2950 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

On to step 12:
The number 315 fits into 1150 3 times, leaving a remainder of 205.
The number 3 becomes the next digit in our result. 
Result so far: 65037.6793
If we subtract 945 from 1150, we get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Let's proceed to step 13:
The number 315 fits into 2050 6 times, leaving a remainder of 160.
Use 6 as the next digit of our solution. 
Result so far: 65037.67936
If we subtract 1890 from 2050, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 14:
315 goes into 1600 5 times with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 65037.679365
Subtracting 1575 from 1600 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 15:
When dividing 250 by 315, we get 0 with a remainder of 250.
Write down 0 as next digit of the result. 
Result so far: 65037.679365
The remainder is 250 after subtracting 0 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 16:
When dividing 2500 by 315, we get 7 with a remainder of 295.
The number 7 becomes the next digit in our result. 
Result so far: 65037.67936507
Subtract 2205 from 2500 to get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Our division results in 65037.67936507 with a remaining 2.95e-07.
