Let's divide 23551188 by 855
We want to divide 23551188 by 855.

Going ahead to step 1:
The number 855 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 855

Moving on to step 2:
855 can be fit into 23 0 times, resulting in a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 23 and we're left with 23.
Fetch the next digit (5) from the dividend, attach it to 23 and continue: 235 / 855

Advancing to step 3:
When dividing 235 by 855, we get 0 with a remainder of 235.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 235, we get 235.
Append the next digit (5) from the dividend to 235 and continue with: 2355 / 855

On to step 4:
The number 855 fits into 2355 2 times, leaving a remainder of 645.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 1710 from 2355, we get 645.
Grab the next digit (1) from the dividend, add it to 645, then carry on: 6451 / 855

Moving on to step 5:
The number 855 fits into 6451 7 times, leaving a remainder of 466.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
If we take 5985 away from 6451, we end up with 466.
Include the next digit (1) from the dividend after 466, then repeat: 4661 / 855

Let's proceed to step 6:
If we divide 4661 by 855, we get 5 and a remainder of 386.
Use 5 as the next digit of our solution. 
Result so far: 275.0
If we subtract 4275 from 4661, we get 386.
Bring next digit (8) of the dividend behind the 386 and repeat the process: 3868 / 855

Advancing to step 7:
If we divide 3868 by 855, we get 4 and a remainder of 448.
Put 4 as the next digit of the answer. 
Result so far: 2754.0
If we take 3420 away from 3868, we end up with 448.
Fetch the next digit (8) from the dividend, attach it to 448 and continue: 4488 / 855

On to step 8:
If we divide 4488 by 855, we get 5 and a remainder of 213.
The number 5 becomes the next digit in our result. 
Result so far: 27545.0
Subtract 4275 from 4488 to get 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Advancing to step 9:
If we divide 2130 by 855, we get 2 and a remainder of 420.
The next digit of our result is 2. 
Result so far: 27545.2
If we subtract 1710 from 2130, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 10:
When dividing 4200 by 855, we get 4 with a remainder of 780.
The next digit of our result is 4. 
Result so far: 27545.24
Deduct 3420 from 4200 and we're left with 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 11:
7800 divided by 855 is 9 with a remainder of 105.
Put 9 as the next digit of the answer. 
Result so far: 27545.249
The remainder is 105 after subtracting 7695 from 7800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

On to step 12:
1050 divided by 855 is 1 with a remainder of 195.
Record the quotient 1 as the next digit in the result. 
Result so far: 27545.2491
Deduct 855 from 1050 and we're left 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.

Moving on to step 13:
If we divide 1950 by 855, we get 2 and a remainder of 240.
Record the quotient 2 as the next digit in the result. 
Result so far: 27545.24912
The remainder is 240 after subtracting 1710 from 1950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 14:
855 can be fit into 2400 2 times, resulting in a remainder of 690.
The number 2 becomes the next digit in our result. 
Result so far: 27545.249122
If we take 1710 away from 2400, we end up with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

After the division, we end up with 27545.249122 and a remainder of 6.9e-05.
