We're dividing 38430686 by 853 
We're looking to find how many times 853 goes into 38430686.

Let's proceed to step 1:
3 divided by 853 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 853

Let's proceed to step 2:
When dividing 38 by 853, we get 0 with a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Bring next digit (4) of the dividend behind the 38 and repeat the process: 384 / 853

Going ahead to step 3:
When dividing 384 by 853, we get 0 with a remainder of 384.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 384 leaves us with 384.
Append the next digit (3) from the dividend to 384 and continue with: 3843 / 853

Moving on to step 4:
3843 divided by 853 is 4 with a remainder of 431.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 3412 from 3843 to get 431.
Bring next digit (0) of the dividend behind the 431 and repeat the process: 4310 / 853

Going ahead to step 5:
4310 divided by 853 is 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 45.0
If we subtract 4265 from 4310, we get 45.
Take the next digit (6) from the dividend and append it to 45, then repeat: 456 / 853

Advancing to step 6:
If we divide 456 by 853, we get 0 and a remainder of 456.
Put 0 as the next digit of the answer. 
Result so far: 450.0
The remainder is 456 after subtracting 0 from 456.
Append the next digit (8) from the dividend to 456 and continue with: 4568 / 853

Going ahead to step 7:
When dividing 4568 by 853, we get 5 with a remainder of 303.
The number 5 becomes the next digit in our result. 
Result so far: 4505.0
Subtract 4265 from 4568 to get 303.
Append the next digit (6) from the dividend to 303 and continue with: 3036 / 853

Advancing to step 8:
If we divide 3036 by 853, we get 3 and a remainder of 477.
Use 3 as the next digit of our solution. 
Result so far: 45053.0
Deduct 2559 from 3036 and we're left with 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

Step 9:
The number 853 fits into 4770 5 times, leaving a remainder of 505.
Write down 5 as next digit of the result. 
Result so far: 45053.5
Deduct 4265 from 4770 and we're left with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Going ahead to step 10:
The number 853 fits into 5050 5 times, leaving a remainder of 785.
The next digit of our result is 5. 
Result so far: 45053.55
If we subtract 4265 from 5050, we get 785.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7850, and continue the process.

Our division results in 45053.55 with a remaining 0.785.
