We look at the division of 53330978 by 851 
Our goal is to divide 53330978 by 851.

On to step 1:
851 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 851

Let's proceed to step 2:
851 can be fit into 53 0 times, resulting in a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Fetch the next digit (3) from the dividend, attach it to 53 and continue: 533 / 851

Advancing to step 3:
The number 851 fits into 533 0 times, leaving a remainder of 533.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 533 leaves us with 533.
Grab the next digit (3) from the dividend, add it to 533, then carry on: 5333 / 851

Let's proceed to step 4:
851 can be fit into 5333 6 times, resulting in a remainder of 227.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 5106 away from 5333, we end up with 227.
Take the next digit (0) from the dividend and append it to 227, then repeat: 2270 / 851

Going ahead to step 5:
When dividing 2270 by 851, we get 2 with a remainder of 568.
Write down 2 as next digit of the result. 
Result so far: 62.0
If we subtract 1702 from 2270, we get 568.
Take the next digit (9) from the dividend and append it to 568, then repeat: 5689 / 851

Let's proceed to step 6:
851 can be fit into 5689 6 times, resulting in a remainder of 583.
Record the quotient 6 as the next digit in the result. 
Result so far: 626.0
Subtracting 5106 from 5689 leaves us with 583.
Grab the next digit (7) from the dividend, add it to 583, then carry on: 5837 / 851

Step 7:
When dividing 5837 by 851, we get 6 with a remainder of 731.
Write down 6 as next digit of the result. 
Result so far: 6266.0
Subtract 5106 from 5837 to get 731.
Grab the next digit (8) from the dividend, add it to 731, then carry on: 7318 / 851

On to step 8:
If we divide 7318 by 851, we get 8 and a remainder of 510.
Record the quotient 8 as the next digit in the result. 
Result so far: 62668.0
If we subtract 6808 from 7318, we get 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Going ahead to step 9:
If we divide 5100 by 851, we get 5 and a remainder of 845.
Use 5 as the next digit of our solution. 
Result so far: 62668.5
If we subtract 4255 from 5100, we get 845.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8450, and continue the process.

Advancing to step 10:
The number 851 fits into 8450 9 times, leaving a remainder of 791.
The next digit of our result is 9. 
Result so far: 62668.59
If we take 7659 away from 8450, we end up with 791.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7910, and continue the process.

On to step 11:
When dividing 7910 by 851, we get 9 with a remainder of 251.
Use 9 as the next digit of our solution. 
Result so far: 62668.599
Deduct 7659 from 7910 and we're left with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

The quotient of the division is 62668.599, and the remainder is 0.0251.
