31245095 ÷ 855 
We want to figure out the number of times 31245095 can be divided by 855.

Step 1:
855 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 855

On to step 2:
When dividing 31 by 855, we get 0 with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Include the next digit (2) from the dividend after 31, then repeat: 312 / 855

On to step 3:
312 divided by 855 is 0 with a remainder of 312.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 312 to get 312.
Take the next digit (4) from the dividend and append it to 312, then repeat: 3124 / 855

Let's proceed to step 4:
When dividing 3124 by 855, we get 3 with a remainder of 559.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 2565 from 3124 leaves us with 559.
Bring next digit (5) of the dividend behind the 559 and repeat the process: 5595 / 855

Let's proceed to step 5:
855 goes into 5595 6 times with a remainder of 465.
Use 6 as the next digit of our solution. 
Result so far: 36.0
Subtract 5130 from 5595 to get 465.
Bring next digit (0) of the dividend behind the 465 and repeat the process: 4650 / 855

Advancing to step 6:
If we divide 4650 by 855, we get 5 and a remainder of 375.
Write down 5 as next digit of the result. 
Result so far: 365.0
If we subtract 4275 from 4650, we get 375.
Fetch the next digit (9) from the dividend, attach it to 375 and continue: 3759 / 855

Step 7:
855 goes into 3759 4 times with a remainder of 339.
The number 4 becomes the next digit in our result. 
Result so far: 3654.0
If we take 3420 away from 3759, we end up with 339.
Append the next digit (5) from the dividend to 339 and continue with: 3395 / 855

On to step 8:
855 can be fit into 3395 3 times, resulting in a remainder of 830.
Put 3 as the next digit of the answer. 
Result so far: 36543.0
If we take 2565 away from 3395, we end up with 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8300, and continue the process.

Moving on to step 9:
When dividing 8300 by 855, we get 9 with a remainder of 605.
Record the quotient 9 as the next digit in the result. 
Result so far: 36543.9
Subtract 7695 from 8300 to get 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

Going ahead to step 10:
If we divide 6050 by 855, we get 7 and a remainder of 65.
Use 7 as the next digit of our solution. 
Result so far: 36543.97
Subtract 5985 from 6050 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 11:
The number 855 fits into 650 0 times, leaving a remainder of 650.
Use 0 as the next digit of our solution. 
Result so far: 36543.97
If we subtract 0 from 650, we get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

On to step 12:
855 goes into 6500 7 times with a remainder of 515.
The next digit of our result is 7. 
Result so far: 36543.9707
Subtract 5985 from 6500 to get 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Step 13:
When dividing 5150 by 855, we get 6 with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 36543.97076
Subtract 5130 from 5150 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 14:
If we divide 200 by 855, we get 0 and a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 36543.97076
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 15:
When dividing 2000 by 855, we get 2 with a remainder of 290.
Record the quotient 2 as the next digit in the result. 
Result so far: 36543.9707602
If we subtract 1710 from 2000, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Moving on to step 16:
The number 855 fits into 2900 3 times, leaving a remainder of 335.
The next digit of our result is 3. 
Result so far: 36543.97076023
The remainder is 335 after subtracting 2565 from 2900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Our division results in 36543.97076023 with a remaining 3.35e-07.
