51981565 divided by 852 
We want to divide 51981565 by 852.

Let's proceed to step 1:
The number 852 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 852

Advancing to step 2:
852 can be fit into 51 0 times, resulting in a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Append the next digit (9) from the dividend to 51 and continue with: 519 / 852

Moving on to step 3:
519 divided by 852 is 0 with a remainder of 519.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 519, we get 519.
Grab the next digit (8) from the dividend, add it to 519, then carry on: 5198 / 852

On to step 4:
The number 852 fits into 5198 6 times, leaving a remainder of 86.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 5112 from 5198 and we're left with 86.
Append the next digit (1) from the dividend to 86 and continue with: 861 / 852

Step 5:
If we divide 861 by 852, we get 1 and a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 61.0
Subtract 852 from 861 to get 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 852

Going ahead to step 6:
852 goes into 95 0 times with a remainder of 95.
The next digit of our result is 0. 
Result so far: 610.0
If we subtract 0 from 95, we get 95.
Grab the next digit (6) from the dividend, add it to 95, then carry on: 956 / 852

Going ahead to step 7:
852 can be fit into 956 1 times, resulting in a remainder of 104.
Write down 1 as next digit of the result. 
Result so far: 6101.0
Subtract 852 from 956 to get 104.
Grab the next digit (5) from the dividend, add it to 104, then carry on: 1045 / 852

Advancing to step 8:
When dividing 1045 by 852, we get 1 with a remainder of 193.
Use 1 as the next digit of our solution. 
Result so far: 61011.0
Deduct 852 from 1045 and we're left with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Moving on to step 9:
852 goes into 1930 2 times with a remainder of 226.
Write down 2 as next digit of the result. 
Result so far: 61011.2
The remainder is 226 after subtracting 1704 from 1930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Step 10:
852 goes into 2260 2 times with a remainder of 556.
Record the quotient 2 as the next digit in the result. 
Result so far: 61011.22
Subtracting 1704 from 2260 leaves us with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

The final result is 61011.22 with a remainder of 0.556.
