Let's divide 18706326 by 855
Our goal is to divide 18706326 by 855.

Step 1:
855 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 855

Step 2:
When dividing 18 by 855, we get 0 with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 855

Going ahead to step 3:
187 divided by 855 is 0 with a remainder of 187.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 187 to get 187.
Fetch the next digit (0) from the dividend, attach it to 187 and continue: 1870 / 855

Going ahead to step 4:
855 can be fit into 1870 2 times, resulting in a remainder of 160.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 1710 from 1870 and we're left with 160.
Include the next digit (6) from the dividend after 160, then repeat: 1606 / 855

Moving on to step 5:
When dividing 1606 by 855, we get 1 with a remainder of 751.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtract 855 from 1606 to get 751.
Bring next digit (3) of the dividend behind the 751 and repeat the process: 7513 / 855

Going ahead to step 6:
7513 divided by 855 is 8 with a remainder of 673.
Put 8 as the next digit of the answer. 
Result so far: 218.0
If we take 6840 away from 7513, we end up with 673.
Bring next digit (2) of the dividend behind the 673 and repeat the process: 6732 / 855

Advancing to step 7:
855 goes into 6732 7 times with a remainder of 747.
Use 7 as the next digit of our solution. 
Result so far: 2187.0
If we take 5985 away from 6732, we end up with 747.
Bring next digit (6) of the dividend behind the 747 and repeat the process: 7476 / 855

Let's proceed to step 8:
855 can be fit into 7476 8 times, resulting in a remainder of 636.
Write down 8 as next digit of the result. 
Result so far: 21878.0
Deduct 6840 from 7476 and we're left with 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Going ahead to step 9:
When dividing 6360 by 855, we get 7 with a remainder of 375.
The number 7 becomes the next digit in our result. 
Result so far: 21878.7
If we subtract 5985 from 6360, we get 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 10:
If we divide 3750 by 855, we get 4 and a remainder of 330.
Write down 4 as next digit of the result. 
Result so far: 21878.74
Subtracting 3420 from 3750 leaves us 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.

On to step 11:
If we divide 3300 by 855, we get 3 and a remainder of 735.
Record the quotient 3 as the next digit in the result. 
Result so far: 21878.743
If we subtract 2565 from 3300, we get 735.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7350, and continue the process.

Let's proceed to step 12:
7350 divided by 855 is 8 with a remainder of 510.
Write down 8 as next digit of the result. 
Result so far: 21878.7438
Subtract 6840 from 7350 to get 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Going ahead to step 13:
5100 divided by 855 is 5 with a remainder of 825.
The number 5 becomes the next digit in our result. 
Result so far: 21878.74385
Subtract 4275 from 5100 to get 825.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8250, and continue the process.

Moving on to step 14:
855 can be fit into 8250 9 times, resulting in a remainder of 555.
The number 9 becomes the next digit in our result. 
Result so far: 21878.743859
If we take 7695 away from 8250, we end up with 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Moving on to step 15:
5550 divided by 855 is 6 with a remainder of 420.
Put 6 as the next digit of the answer. 
Result so far: 21878.7438596
Subtracting 5130 from 5550 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 16:
4200 divided by 855 is 4 with a remainder of 780.
The number 4 becomes the next digit in our result. 
Result so far: 21878.74385964
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.

The final result is 21878.74385964 with a remainder of 7.8e-07.
