Let's divide 7456404 by 855
We're looking to find how many times 855 goes into 7456404.

Step 1:
When dividing 7 by 855, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 855

Moving on to step 2:
If we divide 74 by 855, we get 0 and a remainder of 74.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Include the next digit (5) from the dividend after 74, then repeat: 745 / 855

Step 3:
When dividing 745 by 855, we get 0 with a remainder of 745.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 745 to get 745.
Append the next digit (6) from the dividend to 745 and continue with: 7456 / 855

Going ahead to step 4:
When dividing 7456 by 855, we get 8 with a remainder of 616.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 6840 from 7456 and we're left with 616.
Bring next digit (4) of the dividend behind the 616 and repeat the process: 6164 / 855

On to step 5:
6164 divided by 855 is 7 with a remainder of 179.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
Subtracting 5985 from 6164 leaves us with 179.
Bring next digit (0) of the dividend behind the 179 and repeat the process: 1790 / 855

Step 6:
1790 divided by 855 is 2 with a remainder of 80.
The number 2 becomes the next digit in our result. 
Result so far: 872.0
The remainder is 80 after subtracting 1710 from 1790.
Append the next digit (4) from the dividend to 80 and continue with: 804 / 855

Step 7:
855 goes into 804 0 times with a remainder of 804.
Write down 0 as next digit of the result. 
Result so far: 8720.0
If we take 0 away from 804, we end up with 804.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8040, and continue the process.

On to step 8:
8040 divided by 855 is 9 with a remainder of 345.
Record the quotient 9 as the next digit in the result. 
Result so far: 8720.9
The remainder is 345 after subtracting 7695 from 8040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Step 9:
3450 divided by 855 is 4 with a remainder of 30.
The next digit of our result is 4. 
Result so far: 8720.94
Deduct 3420 from 3450 and we're left 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.

On to step 10:
855 can be fit into 300 0 times, resulting in a remainder of 300.
The next digit of our result is 0. 
Result so far: 8720.94
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 11:
855 can be fit into 3000 3 times, resulting in a remainder of 435.
Write down 3 as next digit of the result. 
Result so far: 8720.9403
Subtract 2565 from 3000 to get 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Moving on to step 12:
855 can be fit into 4350 5 times, resulting in a remainder of 75.
The next digit of our result is 5. 
Result so far: 8720.94035
The remainder is 75 after subtracting 4275 from 4350.
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 13:
If we divide 750 by 855, we get 0 and a remainder of 750.
Use 0 as the next digit of our solution. 
Result so far: 8720.94035
Deduct 0 from 750 and we're left with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

On to step 14:
855 can be fit into 7500 8 times, resulting in a remainder of 660.
Write down 8 as next digit of the result. 
Result so far: 8720.9403508
If we take 6840 away from 7500, we end up with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

On to step 15:
The number 855 fits into 6600 7 times, leaving a remainder of 615.
Write down 7 as next digit of the result. 
Result so far: 8720.94035087
Subtract 5985 from 6600 to get 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

In conclusion, the division gives 8720.94035087 with a balance of 6.15e-07.
