We're dividing 78528053 by 853 
We want to divide 78528053 by 853.

Step 1:
If we divide 7 by 853, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 853

Let's proceed to step 2:
78 divided by 853 is 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Grab the next digit (5) from the dividend, add it to 78, then carry on: 785 / 853

Let's proceed to step 3:
The number 853 fits into 785 0 times, leaving a remainder of 785.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 785 after subtracting 0 from 785.
Include the next digit (2) from the dividend after 785, then repeat: 7852 / 853

Moving on to step 4:
7852 divided by 853 is 9 with a remainder of 175.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 7677 away from 7852, we end up with 175.
Bring next digit (8) of the dividend behind the 175 and repeat the process: 1758 / 853

Step 5:
853 goes into 1758 2 times with a remainder of 52.
Record the quotient 2 as the next digit in the result. 
Result so far: 92.0
If we take 1706 away from 1758, we end up with 52.
Fetch the next digit (0) from the dividend, attach it to 52 and continue: 520 / 853

Going ahead to step 6:
When dividing 520 by 853, we get 0 with a remainder of 520.
Write down 0 as next digit of the result. 
Result so far: 920.0
Subtract 0 from 520 to get 520.
Bring next digit (5) of the dividend behind the 520 and repeat the process: 5205 / 853

Step 7:
When dividing 5205 by 853, we get 6 with a remainder of 87.
Record the quotient 6 as the next digit in the result. 
Result so far: 9206.0
If we take 5118 away from 5205, we end up with 87.
Grab the next digit (3) from the dividend, add it to 87, then carry on: 873 / 853

Advancing to step 8:
853 goes into 873 1 times with a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 92061.0
If we take 853 away from 873, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
200 divided by 853 is 0 with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 92061.0
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 10:
2000 divided by 853 is 2 with a remainder of 294.
Write down 2 as next digit of the result. 
Result so far: 92061.02
Subtract 1706 from 2000 to get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Moving on to step 11:
2940 divided by 853 is 3 with a remainder of 381.
Write down 3 as next digit of the result. 
Result so far: 92061.023
Subtracting 2559 from 2940 leaves us with 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Let's proceed to step 12:
When dividing 3810 by 853, we get 4 with a remainder of 398.
The number 4 becomes the next digit in our result. 
Result so far: 92061.0234
Subtracting 3412 from 3810 leaves us with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Let's proceed to step 13:
The number 853 fits into 3980 4 times, leaving a remainder of 568.
Put 4 as the next digit of the answer. 
Result so far: 92061.02344
Subtracting 3412 from 3980 leaves us with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

The final result is 92061.02344 with a remainder of 0.000568.
