We're dividing 39187563 by 855 
We're looking to find how many times 855 goes into 39187563.

Step 1:
When dividing 3 by 855, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 855

Let's proceed to step 2:
855 goes into 39 0 times with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Grab the next digit (1) from the dividend, add it to 39, then carry on: 391 / 855

Step 3:
When dividing 391 by 855, we get 0 with a remainder of 391.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 391 leaves us with 391.
Append the next digit (8) from the dividend to 391 and continue with: 3918 / 855

Advancing to step 4:
3918 divided by 855 is 4 with a remainder of 498.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 498 after subtracting 3420 from 3918.
Bring next digit (7) of the dividend behind the 498 and repeat the process: 4987 / 855

Let's proceed to step 5:
If we divide 4987 by 855, we get 5 and a remainder of 712.
Write down 5 as next digit of the result. 
Result so far: 45.0
If we subtract 4275 from 4987, we get 712.
Bring next digit (5) of the dividend behind the 712 and repeat the process: 7125 / 855

Advancing to step 6:
The number 855 fits into 7125 8 times, leaving a remainder of 285.
The number 8 becomes the next digit in our result. 
Result so far: 458.0
Subtracting 6840 from 7125 leaves us with 285.
Append the next digit (6) from the dividend to 285 and continue with: 2856 / 855

Going ahead to step 7:
2856 divided by 855 is 3 with a remainder of 291.
The next digit of our result is 3. 
Result so far: 4583.0
The remainder is 291 after subtracting 2565 from 2856.
Bring next digit (3) of the dividend behind the 291 and repeat the process: 2913 / 855

On to step 8:
2913 divided by 855 is 3 with a remainder of 348.
Use 3 as the next digit of our solution. 
Result so far: 45833.0
If we subtract 2565 from 2913, we get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Let's proceed to step 9:
855 can be fit into 3480 4 times, resulting in a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 45833.4
The remainder is 60 after subtracting 3420 from 3480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
The number 855 fits into 600 0 times, leaving a remainder of 600.
The next digit of our result is 0. 
Result so far: 45833.4
The remainder is 600 after subtracting 0 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 11:
855 can be fit into 6000 7 times, resulting in a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 45833.407
Subtract 5985 from 6000 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 12:
150 divided by 855 is 0 with a remainder of 150.
The next digit of our result is 0. 
Result so far: 45833.407
Subtracting 0 from 150 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 13:
When dividing 1500 by 855, we get 1 with a remainder of 645.
Use 1 as the next digit of our solution. 
Result so far: 45833.40701
Subtract 855 from 1500 to get 645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

Let's proceed to step 14:
The number 855 fits into 6450 7 times, leaving a remainder of 465.
Put 7 as the next digit of the answer. 
Result so far: 45833.407017
The remainder is 465 after subtracting 5985 from 6450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Advancing to step 15:
The number 855 fits into 4650 5 times, leaving a remainder of 375.
The number 5 becomes the next digit in our result. 
Result so far: 45833.4070175
If we take 4275 away from 4650, we end up with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Let's proceed to step 16:
3750 divided by 855 is 4 with a remainder of 330.
Write down 4 as next digit of the result. 
Result so far: 45833.40701754
If we take 3420 away from 3750, we end up with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

The final result is 45833.40701754 with a remainder of 3.3e-07.
