Let's divide 13666143 by 785
We're looking to find how many times 785 goes into 13666143.

On to step 1:
If we divide 1 by 785, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 785

Let's proceed to step 2:
The number 785 fits into 13 0 times, leaving a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Include the next digit (6) from the dividend after 13, then repeat: 136 / 785

Step 3:
136 divided by 785 is 0 with a remainder of 136.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 136 after subtracting 0 from 136.
Fetch the next digit (6) from the dividend, attach it to 136 and continue: 1366 / 785

Step 4:
If we divide 1366 by 785, we get 1 and a remainder of 581.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 785 from 1366, we get 581.
Take the next digit (6) from the dividend and append it to 581, then repeat: 5816 / 785

Moving on to step 5:
5816 divided by 785 is 7 with a remainder of 321.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Deduct 5495 from 5816 and we're left with 321.
Append the next digit (1) from the dividend to 321 and continue with: 3211 / 785

Step 6:
3211 divided by 785 is 4 with a remainder of 71.
Use 4 as the next digit of our solution. 
Result so far: 174.0
The remainder is 71 after subtracting 3140 from 3211.
Grab the next digit (4) from the dividend, add it to 71, then carry on: 714 / 785

Step 7:
When dividing 714 by 785, we get 0 with a remainder of 714.
The next digit of our result is 0. 
Result so far: 1740.0
Subtract 0 from 714 to get 714.
Append the next digit (3) from the dividend to 714 and continue with: 7143 / 785

On to step 8:
The number 785 fits into 7143 9 times, leaving a remainder of 78.
The number 9 becomes the next digit in our result. 
Result so far: 17409.0
If we subtract 7065 from 7143, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 9:
The number 785 fits into 780 0 times, leaving a remainder of 780.
Put 0 as the next digit of the answer. 
Result so far: 17409.0
Deduct 0 from 780 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.

Going ahead to step 10:
7800 divided by 785 is 9 with a remainder of 735.
Put 9 as the next digit of the answer. 
Result so far: 17409.09
The remainder is 735 after subtracting 7065 from 7800.
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 11:
If we divide 7350 by 785, we get 9 and a remainder of 285.
Write down 9 as next digit of the result. 
Result so far: 17409.099
Subtract 7065 from 7350 to get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

The final outcome is 17409.099, with a leftover of 0.0285.
