Let's divide 51963809 by 853
We're looking to find how many times 853 goes into 51963809.

Let's proceed to step 1:
If we divide 5 by 853, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 853

Advancing to step 2:
The number 853 fits into 51 0 times, leaving a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Fetch the next digit (9) from the dividend, attach it to 51 and continue: 519 / 853

Step 3:
When dividing 519 by 853, we get 0 with a remainder of 519.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 519, we get 519.
Grab the next digit (6) from the dividend, add it to 519, then carry on: 5196 / 853

Step 4:
853 can be fit into 5196 6 times, resulting in a remainder of 78.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 5118 from 5196 and we're left with 78.
Include the next digit (3) from the dividend after 78, then repeat: 783 / 853

Going ahead to step 5:
If we divide 783 by 853, we get 0 and a remainder of 783.
Use 0 as the next digit of our solution. 
Result so far: 60.0
Deduct 0 from 783 and we're left with 783.
Bring next digit (8) of the dividend behind the 783 and repeat the process: 7838 / 853

Advancing to step 6:
853 goes into 7838 9 times with a remainder of 161.
Record the quotient 9 as the next digit in the result. 
Result so far: 609.0
Deduct 7677 from 7838 and we're left with 161.
Grab the next digit (0) from the dividend, add it to 161, then carry on: 1610 / 853

Let's proceed to step 7:
When dividing 1610 by 853, we get 1 with a remainder of 757.
The number 1 becomes the next digit in our result. 
Result so far: 6091.0
Deduct 853 from 1610 and we're left with 757.
Take the next digit (9) from the dividend and append it to 757, then repeat: 7579 / 853

Moving on to step 8:
853 goes into 7579 8 times with a remainder of 755.
The next digit of our result is 8. 
Result so far: 60918.0
Deduct 6824 from 7579 and we're left 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 9:
If we divide 7550 by 853, we get 8 and a remainder of 726.
Record the quotient 8 as the next digit in the result. 
Result so far: 60918.8
If we subtract 6824 from 7550, we get 726.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7260, and continue the process.

Going ahead to step 10:
853 goes into 7260 8 times with a remainder of 436.
Record the quotient 8 as the next digit in the result. 
Result so far: 60918.88
Subtract 6824 from 7260 to get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

After the division, we end up with 60918.88 and a remainder of 0.436.
