Let's divide 13388660 by 855
We want to divide 13388660 by 855.

Going ahead to step 1:
If we divide 1 by 855, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 855

Advancing to step 2:
13 divided by 855 is 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 855

Step 3:
133 divided by 855 is 0 with a remainder of 133.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 133, we end up with 133.
Bring next digit (8) of the dividend behind the 133 and repeat the process: 1338 / 855

Going ahead to step 4:
If we divide 1338 by 855, we get 1 and a remainder of 483.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 855 away from 1338, we end up with 483.
Append the next digit (8) from the dividend to 483 and continue with: 4838 / 855

Moving on to step 5:
If we divide 4838 by 855, we get 5 and a remainder of 563.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 563 after subtracting 4275 from 4838.
Take the next digit (6) from the dividend and append it to 563, then repeat: 5636 / 855

Going ahead to step 6:
855 goes into 5636 6 times with a remainder of 506.
Write down 6 as next digit of the result. 
Result so far: 156.0
Deduct 5130 from 5636 and we're left with 506.
Grab the next digit (6) from the dividend, add it to 506, then carry on: 5066 / 855

Step 7:
855 goes into 5066 5 times with a remainder of 791.
Use 5 as the next digit of our solution. 
Result so far: 1565.0
Subtract 4275 from 5066 to get 791.
Fetch the next digit (0) from the dividend, attach it to 791 and continue: 7910 / 855

Advancing to step 8:
If we divide 7910 by 855, we get 9 and a remainder of 215.
The number 9 becomes the next digit in our result. 
Result so far: 15659.0
The remainder is 215 after subtracting 7695 from 7910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Step 9:
2150 divided by 855 is 2 with a remainder of 440.
Put 2 as the next digit of the answer. 
Result so far: 15659.2
Subtract 1710 from 2150 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Step 10:
If we divide 4400 by 855, we get 5 and a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 15659.25
Subtracting 4275 from 4400 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 11:
The number 855 fits into 1250 1 times, leaving a remainder of 395.
Write down 1 as next digit of the result. 
Result so far: 15659.251
If we take 855 away from 1250, we end up with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Let's proceed to step 12:
855 can be fit into 3950 4 times, resulting in a remainder of 530.
The number 4 becomes the next digit in our result. 
Result so far: 15659.2514
If we take 3420 away from 3950, we end up with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Going ahead to step 13:
When dividing 5300 by 855, we get 6 with a remainder of 170.
Write down 6 as next digit of the result. 
Result so far: 15659.25146
Subtract 5130 from 5300 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 14:
855 goes into 1700 1 times with a remainder of 845.
Put 1 as the next digit of the answer. 
Result so far: 15659.251461
Subtract 855 from 1700 to get 845.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8450, and continue the process.

On to step 15:
If we divide 8450 by 855, we get 9 and a remainder of 755.
Put 9 as the next digit of the answer. 
Result so far: 15659.2514619
Subtracting 7695 from 8450 leaves us with 755.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7550, and continue the process.

Let's proceed to step 16:
The number 855 fits into 7550 8 times, leaving a remainder of 710.
Use 8 as the next digit of our solution. 
Result so far: 15659.25146198
The remainder is 710 after subtracting 6840 from 7550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

The final result is 15659.25146198 with a remainder of 7.1e-07.
