318789 ÷ 51 
Our goal is to divide 318789 by 51.

On to step 1:
If we divide 3 by 51, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 51

Advancing to step 2:
The number 51 fits into 31 0 times, leaving a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Bring next digit (8) of the dividend behind the 31 and repeat the process: 318 / 51

Moving on to step 3:
51 can be fit into 318 6 times, resulting in a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 12 after subtracting 306 from 318.
Take the next digit (7) from the dividend and append it to 12, then repeat: 127 / 51

Step 4:
If we divide 127 by 51, we get 2 and a remainder of 25.
Put 2 as the next digit of the answer. 
Result so far: 62.0
If we subtract 102 from 127, we get 25.
Append the next digit (8) from the dividend to 25 and continue with: 258 / 51

Advancing to step 5:
If we divide 258 by 51, we get 5 and a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 625.0
The remainder is 3 after subtracting 255 from 258.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 51

On to step 6:
39 divided by 51 is 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 6250.0
If we take 0 away from 39, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 7:
51 goes into 390 7 times with a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 6250.7
Deduct 357 from 390 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 8:
When dividing 330 by 51, we get 6 with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 6250.76
Subtracting 306 from 330 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.

Step 9:
The number 51 fits into 240 4 times, leaving a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 6250.764
Subtract 204 from 240 to 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.

Going ahead to step 10:
51 can be fit into 360 7 times, resulting in a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 6250.7647
If we subtract 357 from 360, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 11:
The number 51 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 6250.7647
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
When dividing 300 by 51, we get 5 with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 6250.764705
Subtracting 255 from 300 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 13:
The number 51 fits into 450 8 times, leaving a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 6250.7647058
The remainder is 42 after subtracting 408 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 14:
420 divided by 51 is 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 6250.76470588
If we take 408 away from 420, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 6250.76470588, with a leftover of 1.2e-08.
