853770 divided by 51 
We want to divide 853770 by 51.

Going ahead to step 1:
8 divided by 51 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 51

Advancing to step 2:
If we divide 85 by 51, we get 1 and a remainder of 34.
The next digit of our result is 1. 
Result so far: 1.0
If we take 51 away from 85, we end up with 34.
Append the next digit (3) from the dividend to 34 and continue with: 343 / 51

Let's proceed to step 3:
The number 51 fits into 343 6 times, leaving a remainder of 37.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we take 306 away from 343, we end up with 37.
Bring next digit (7) of the dividend behind the 37 and repeat the process: 377 / 51

Advancing to step 4:
377 divided by 51 is 7 with a remainder of 20.
The next digit of our result is 7. 
Result so far: 167.0
Deduct 357 from 377 and we're left with 20.
Include the next digit (7) from the dividend after 20, then repeat: 207 / 51

Let's proceed to step 5:
The number 51 fits into 207 4 times, leaving a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 1674.0
Subtract 204 from 207 to get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 51

Advancing to step 6:
51 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 16740.0
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 7:
If we divide 300 by 51, we get 5 and a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 16740.5
Subtracting 255 from 300 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 8:
51 goes into 450 8 times with a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 16740.58
Subtract 408 from 450 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 9:
420 divided by 51 is 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 16740.588
If we take 408 away from 420, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 16740.588, and the remainder is 0.0012.
