We divide 52521986 by 53
We're looking to find how many times 53 goes into 52521986.

On to step 1:
53 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 53

Going ahead to step 2:
53 can be fit into 52 0 times, resulting in a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Fetch the next digit (5) from the dividend, attach it to 52 and continue: 525 / 53

Let's proceed to step 3:
53 can be fit into 525 9 times, resulting in a remainder of 48.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 477 from 525 leaves us with 48.
Include the next digit (2) from the dividend after 48, then repeat: 482 / 53

Step 4:
If we divide 482 by 53, we get 9 and a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 99.0
Subtract 477 from 482 to get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 53

Going ahead to step 5:
The number 53 fits into 51 0 times, leaving a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 990.0
The remainder is 51 after subtracting 0 from 51.
Grab the next digit (9) from the dividend, add it to 51, then carry on: 519 / 53

On to step 6:
53 goes into 519 9 times with a remainder of 42.
Record the quotient 9 as the next digit in the result. 
Result so far: 9909.0
The remainder is 42 after subtracting 477 from 519.
Bring next digit (8) of the dividend behind the 42 and repeat the process: 428 / 53

Going ahead to step 7:
428 divided by 53 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 99098.0
If we subtract 424 from 428, we get 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 53

On to step 8:
53 goes into 46 0 times with a remainder of 46.
Put 0 as the next digit of the answer. 
Result so far: 990980.0
Deduct 0 from 46 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 9:
The number 53 fits into 460 8 times, leaving a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 990980.8
If we subtract 424 from 460, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 10:
53 can be fit into 360 6 times, resulting in a remainder of 42.
Write down 6 as next digit of the result. 
Result so far: 990980.86
Deduct 318 from 360 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 11:
53 goes into 420 7 times with a remainder of 49.
Put 7 as the next digit of the answer. 
Result so far: 990980.867
Deduct 371 from 420 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 12:
53 goes into 490 9 times with a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 990980.8679
Subtract 477 from 490 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 13:
53 goes into 130 2 times with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 990980.86792
Subtracting 106 from 130 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 14:
53 goes into 240 4 times with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 990980.867924
Subtract 212 from 240 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 15:
280 divided by 53 is 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 990980.8679245
If we take 265 away from 280, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 16:
The number 53 fits into 150 2 times, leaving a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 990980.86792452
The remainder is 44 after subtracting 106 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final outcome is 990980.86792452, with a leftover of 4.4e-08.
