We're dividing 13640755 by 853 
We want to figure out the number of times 13640755 can be divided by 853.

Let's proceed to step 1:
853 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 853

Advancing to step 2:
853 can be fit into 13 0 times, resulting in 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.
Include the next digit (6) from the dividend after 13, then repeat: 136 / 853

Going ahead to step 3:
The number 853 fits into 136 0 times, leaving a remainder of 136.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 136 after subtracting 0 from 136.
Fetch the next digit (4) from the dividend, attach it to 136 and continue: 1364 / 853

Let's proceed to step 4:
If we divide 1364 by 853, we get 1 and a remainder of 511.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 853 from 1364 to get 511.
Grab the next digit (0) from the dividend, add it to 511, then carry on: 5110 / 853

Let's proceed to step 5:
When dividing 5110 by 853, we get 5 with a remainder of 845.
The next digit of our result is 5. 
Result so far: 15.0
If we subtract 4265 from 5110, we get 845.
Fetch the next digit (7) from the dividend, attach it to 845 and continue: 8457 / 853

On to step 6:
The number 853 fits into 8457 9 times, leaving a remainder of 780.
Write down 9 as next digit of the result. 
Result so far: 159.0
Deduct 7677 from 8457 and we're left with 780.
Fetch the next digit (5) from the dividend, attach it to 780 and continue: 7805 / 853

Moving on to step 7:
If we divide 7805 by 853, we get 9 and a remainder of 128.
Use 9 as the next digit of our solution. 
Result so far: 1599.0
Subtract 7677 from 7805 to get 128.
Take the next digit (5) from the dividend and append it to 128, then repeat: 1285 / 853

Moving on to step 8:
1285 divided by 853 is 1 with a remainder of 432.
The number 1 becomes the next digit in our result. 
Result so far: 15991.0
If we take 853 away from 1285, we end up with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Moving on to step 9:
If we divide 4320 by 853, we get 5 and a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 15991.5
Deduct 4265 from 4320 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 10:
853 can be fit into 550 0 times, resulting in a remainder of 550.
Write down 0 as next digit of the result. 
Result so far: 15991.5
If we subtract 0 from 550, we get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Going ahead to step 11:
853 goes into 5500 6 times with a remainder of 382.
The number 6 becomes the next digit in our result. 
Result so far: 15991.506
The remainder is 382 after subtracting 5118 from 5500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Let's proceed to step 12:
853 goes into 3820 4 times with a remainder of 408.
The number 4 becomes the next digit in our result. 
Result so far: 15991.5064
Subtracting 3412 from 3820 leaves us with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Moving on to step 13:
If we divide 4080 by 853, we get 4 and a remainder of 668.
Write down 4 as next digit of the result. 
Result so far: 15991.50644
Deduct 3412 from 4080 and we're left with 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

The final outcome is 15991.50644, with a leftover of 0.000668.
