51221051 divided by 314 
Our goal is to divide 51221051 by 314.

Going ahead to step 1:
314 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 314

Advancing to step 2:
314 goes into 51 0 times with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Bring next digit (2) of the dividend behind the 51 and repeat the process: 512 / 314

Step 3:
314 goes into 512 1 times with a remainder of 198.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 314 from 512 leaves us with 198.
Append the next digit (2) from the dividend to 198 and continue with: 1982 / 314

Moving on to step 4:
The number 314 fits into 1982 6 times, leaving a remainder of 98.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we take 1884 away from 1982, we end up with 98.
Grab the next digit (1) from the dividend, add it to 98, then carry on: 981 / 314

Going ahead to step 5:
The number 314 fits into 981 3 times, leaving a remainder of 39.
Write down 3 as next digit of the result. 
Result so far: 163.0
If we take 942 away from 981, we end up with 39.
Fetch the next digit (0) from the dividend, attach it to 39 and continue: 390 / 314

Advancing to step 6:
When dividing 390 by 314, we get 1 with a remainder of 76.
The number 1 becomes the next digit in our result. 
Result so far: 1631.0
Deduct 314 from 390 and we're left with 76.
Fetch the next digit (5) from the dividend, attach it to 76 and continue: 765 / 314

Step 7:
314 can be fit into 765 2 times, resulting in a remainder of 137.
Put 2 as the next digit of the answer. 
Result so far: 16312.0
Subtract 628 from 765 to get 137.
Bring next digit (1) of the dividend behind the 137 and repeat the process: 1371 / 314

Advancing to step 8:
The number 314 fits into 1371 4 times, leaving a remainder of 115.
The next digit of our result is 4. 
Result so far: 163124.0
If we take 1256 away from 1371, we end up with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Step 9:
The number 314 fits into 1150 3 times, leaving a remainder of 208.
Put 3 as the next digit of the answer. 
Result so far: 163124.3
If we subtract 942 from 1150, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

On to step 10:
314 goes into 2080 6 times with a remainder of 196.
Use 6 as the next digit of our solution. 
Result so far: 163124.36
Deduct 1884 from 2080 and we're left with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Advancing to step 11:
1960 divided by 314 is 6 with a remainder of 76.
Use 6 as the next digit of our solution. 
Result so far: 163124.366
Deduct 1884 from 1960 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final result is 163124.366 with a remainder of 0.0076.
