55365432 divided by 855 
Let's see how many times 855 fits into 55365432.

Let's proceed to step 1:
5 divided by 855 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 855

Moving on to step 2:
855 goes into 55 0 times with a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Include the next digit (3) from the dividend after 55, then repeat: 553 / 855

Moving on to step 3:
855 goes into 553 0 times with a remainder of 553.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 553, we end up with 553.
Append the next digit (6) from the dividend to 553 and continue with: 5536 / 855

Advancing to step 4:
855 can be fit into 5536 6 times, resulting in a remainder of 406.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 5130 from 5536 to get 406.
Grab the next digit (5) from the dividend, add it to 406, then carry on: 4065 / 855

Step 5:
855 can be fit into 4065 4 times, resulting in a remainder of 645.
Put 4 as the next digit of the answer. 
Result so far: 64.0
The remainder is 645 after subtracting 3420 from 4065.
Bring next digit (4) of the dividend behind the 645 and repeat the process: 6454 / 855

Let's proceed to step 6:
855 can be fit into 6454 7 times, resulting in a remainder of 469.
Write down 7 as next digit of the result. 
Result so far: 647.0
Deduct 5985 from 6454 and we're left with 469.
Include the next digit (3) from the dividend after 469, then repeat: 4693 / 855

Going ahead to step 7:
4693 divided by 855 is 5 with a remainder of 418.
The number 5 becomes the next digit in our result. 
Result so far: 6475.0
Subtract 4275 from 4693 to get 418.
Include the next digit (2) from the dividend after 418, then repeat: 4182 / 855

Going ahead to step 8:
When dividing 4182 by 855, we get 4 with a remainder of 762.
Record the quotient 4 as the next digit in the result. 
Result so far: 64754.0
Deduct 3420 from 4182 and we're left with 762.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7620, and continue the process.

On to step 9:
If we divide 7620 by 855, we get 8 and a remainder of 780.
The number 8 becomes the next digit in our result. 
Result so far: 64754.8
Subtract 6840 from 7620 to get 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Step 10:
The number 855 fits into 7800 9 times, leaving a remainder of 105.
The next digit of our result is 9. 
Result so far: 64754.89
If we subtract 7695 from 7800, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Let's proceed to step 11:
If we divide 1050 by 855, we get 1 and a remainder of 195.
Write down 1 as next digit of the result. 
Result so far: 64754.891
If we take 855 away from 1050, we end up with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Step 12:
If we divide 1950 by 855, we get 2 and a remainder of 240.
The next digit of our result is 2. 
Result so far: 64754.8912
If we subtract 1710 from 1950, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 13:
When dividing 2400 by 855, we get 2 with a remainder of 690.
Record the quotient 2 as the next digit in the result. 
Result so far: 64754.89122
Subtract 1710 from 2400 to get 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

The final result is 64754.89122 with a remainder of 0.00069.
