3404748 divided by 855 
We want to figure out the number of times 3404748 can be divided by 855.

Advancing to step 1:
855 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 855

On to step 2:
If we divide 34 by 855, we get 0 and a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 34 and we're left with 34.
Fetch the next digit (0) from the dividend, attach it to 34 and continue: 340 / 855

Going ahead to step 3:
The number 855 fits into 340 0 times, leaving a remainder of 340.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 340 to get 340.
Fetch the next digit (4) from the dividend, attach it to 340 and continue: 3404 / 855

Advancing to step 4:
The number 855 fits into 3404 3 times, leaving a remainder of 839.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 839 after subtracting 2565 from 3404.
Take the next digit (7) from the dividend and append it to 839, then repeat: 8397 / 855

Let's proceed to step 5:
8397 divided by 855 is 9 with a remainder of 702.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Deduct 7695 from 8397 and we're left with 702.
Grab the next digit (4) from the dividend, add it to 702, then carry on: 7024 / 855

Advancing to step 6:
855 goes into 7024 8 times with a remainder of 184.
Record the quotient 8 as the next digit in the result. 
Result so far: 398.0
Subtract 6840 from 7024 to get 184.
Bring next digit (8) of the dividend behind the 184 and repeat the process: 1848 / 855

Let's proceed to step 7:
When dividing 1848 by 855, we get 2 with a remainder of 138.
Put 2 as the next digit of the answer. 
Result so far: 3982.0
Subtracting 1710 from 1848 leaves us with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Step 8:
1380 divided by 855 is 1 with a remainder of 525.
Put 1 as the next digit of the answer. 
Result so far: 3982.1
If we subtract 855 from 1380, we get 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

On to step 9:
The number 855 fits into 5250 6 times, leaving a remainder of 120.
Use 6 as the next digit of our solution. 
Result so far: 3982.16
Subtract 5130 from 5250 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 10:
1200 divided by 855 is 1 with a remainder of 345.
The number 1 becomes the next digit in our result. 
Result so far: 3982.161
The remainder is 345 after subtracting 855 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Let's proceed to step 11:
If we divide 3450 by 855, we get 4 and a remainder of 30.
Use 4 as the next digit of our solution. 
Result so far: 3982.1614
If we take 3420 away from 3450, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 12:
If we divide 300 by 855, we get 0 and a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 3982.1614
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 13:
When dividing 3000 by 855, we get 3 with a remainder of 435.
Use 3 as the next digit of our solution. 
Result so far: 3982.161403
Deduct 2565 from 3000 and we're left with 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Let's proceed to step 14:
If we divide 4350 by 855, we get 5 and a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 3982.1614035
Subtract 4275 from 4350 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 15:
The number 855 fits into 750 0 times, leaving a remainder of 750.
The next digit of our result is 0. 
Result so far: 3982.1614035
If we subtract 0 from 750, we get 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Our division results in 3982.1614035 with a remaining 7.5e-07.
