Let's divide 77561911 by 52
Our goal is to divide 77561911 by 52.

Step 1:
The number 52 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 52

Going ahead to step 2:
52 goes into 77 1 times with a remainder of 25.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 52 from 77 and we're left with 25.
Bring next digit (5) of the dividend behind the 25 and repeat the process: 255 / 52

Moving on to step 3:
52 can be fit into 255 4 times, resulting in a remainder of 47.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 208 from 255, we get 47.
Include the next digit (6) from the dividend after 47, then repeat: 476 / 52

Moving on to step 4:
If we divide 476 by 52, we get 9 and a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 149.0
Subtract 468 from 476 to get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 52

Advancing to step 5:
81 divided by 52 is 1 with a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 1491.0
If we subtract 52 from 81, we get 29.
Fetch the next digit (9) from the dividend, attach it to 29 and continue: 299 / 52

Let's proceed to step 6:
If we divide 299 by 52, we get 5 and a remainder of 39.
The next digit of our result is 5. 
Result so far: 14915.0
Subtract 260 from 299 to get 39.
Grab the next digit (1) from the dividend, add it to 39, then carry on: 391 / 52

Going ahead to step 7:
391 divided by 52 is 7 with a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 149157.0
Deduct 364 from 391 and we're left with 27.
Grab the next digit (1) from the dividend, add it to 27, then carry on: 271 / 52

Advancing to step 8:
The number 52 fits into 271 5 times, leaving a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 1491575.0
The remainder is 11 after subtracting 260 from 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 9:
52 can be fit into 110 2 times, resulting in a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 1491575.2
If we subtract 104 from 110, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 10:
52 goes into 60 1 times with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1491575.21
The remainder is 8 after subtracting 52 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
When dividing 80 by 52, we get 1 with a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 1491575.211
Deduct 52 from 80 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The quotient of the division is 1491575.211, and the remainder is 0.0028.
