343085 ÷ 51 
We want to divide 343085 by 51.

Going ahead to step 1:
51 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 51

Advancing to step 2:
When dividing 34 by 51, we get 0 with a remainder of 34.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 34, we end up with 34.
Take the next digit (3) from the dividend and append it to 34, then repeat: 343 / 51

Moving on to step 3:
If we divide 343 by 51, we get 6 and a remainder of 37.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 37 after subtracting 306 from 343.
Bring next digit (0) of the dividend behind the 37 and repeat the process: 370 / 51

Advancing to step 4:
51 can be fit into 370 7 times, resulting in a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 67.0
Subtract 357 from 370 to get 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 51

On to step 5:
138 divided by 51 is 2 with a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 672.0
The remainder is 36 after subtracting 102 from 138.
Take the next digit (5) from the dividend and append it to 36, then repeat: 365 / 51

Step 6:
51 can be fit into 365 7 times, resulting in a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 6727.0
If we subtract 357 from 365, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
When dividing 80 by 51, we get 1 with a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 6727.1
Subtract 51 from 80 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 8:
51 goes into 290 5 times with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 6727.15
Subtracting 255 from 290 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 9:
When dividing 350 by 51, we get 6 with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 6727.156
Deduct 306 from 350 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 10:
The number 51 fits into 440 8 times, leaving a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 6727.1568
Subtracting 408 from 440 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 11:
When dividing 320 by 51, we get 6 with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 6727.15686
The remainder is 14 after subtracting 306 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 12:
If we divide 140 by 51, we get 2 and a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 6727.156862
If we take 102 away from 140, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 13:
51 can be fit into 380 7 times, resulting in a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 6727.1568627
Subtract 357 from 380 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 14:
The number 51 fits into 230 4 times, leaving a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 6727.15686274
If we subtract 204 from 230, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final outcome is 6727.15686274, with a leftover of 2.6e-08.
