Let's divide 53279786 by 312
We want to divide 53279786 by 312.

On to step 1:
The number 312 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 312

Advancing to step 2:
When dividing 53 by 312, we get 0 with a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Fetch the next digit (2) from the dividend, attach it to 53 and continue: 532 / 312

On to step 3:
532 divided by 312 is 1 with a remainder of 220.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 312 from 532 leaves us with 220.
Fetch the next digit (7) from the dividend, attach it to 220 and continue: 2207 / 312

Going ahead to step 4:
When dividing 2207 by 312, we get 7 with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we take 2184 away from 2207, we end up with 23.
Bring next digit (9) of the dividend behind the 23 and repeat the process: 239 / 312

Going ahead to step 5:
If we divide 239 by 312, we get 0 and a remainder of 239.
The next digit of our result is 0. 
Result so far: 170.0
Deduct 0 from 239 and we're left with 239.
Take the next digit (7) from the dividend and append it to 239, then repeat: 2397 / 312

Advancing to step 6:
When dividing 2397 by 312, we get 7 with a remainder of 213.
Record the quotient 7 as the next digit in the result. 
Result so far: 1707.0
Subtracting 2184 from 2397 leaves us with 213.
Bring next digit (8) of the dividend behind the 213 and repeat the process: 2138 / 312

Advancing to step 7:
The number 312 fits into 2138 6 times, leaving a remainder of 266.
Record the quotient 6 as the next digit in the result. 
Result so far: 17076.0
The remainder is 266 after subtracting 1872 from 2138.
Bring next digit (6) of the dividend behind the 266 and repeat the process: 2666 / 312

Advancing to step 8:
If we divide 2666 by 312, we get 8 and a remainder of 170.
Record the quotient 8 as the next digit in the result. 
Result so far: 170768.0
The remainder is 170 after subtracting 2496 from 2666.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 9:
If we divide 1700 by 312, we get 5 and a remainder of 140.
Use 5 as the next digit of our solution. 
Result so far: 170768.5
The remainder is 140 after subtracting 1560 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 10:
312 can be fit into 1400 4 times, resulting in a remainder of 152.
Use 4 as the next digit of our solution. 
Result so far: 170768.54
The remainder is 152 after subtracting 1248 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 11:
The number 312 fits into 1520 4 times, leaving a remainder of 272.
Record the quotient 4 as the next digit in the result. 
Result so far: 170768.544
If we subtract 1248 from 1520, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

The final result is 170768.544 with a remainder of 0.0272.
