68505 ÷ 51 
Our goal is to divide 68505 by 51.

On to step 1:
51 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 51

Step 2:
51 can be fit into 68 1 times, resulting in a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 51 from 68 and we're left with 17.
Include the next digit (5) from the dividend after 17, then repeat: 175 / 51

Going ahead to step 3:
The number 51 fits into 175 3 times, leaving a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtract 153 from 175 to get 22.
Grab the next digit (0) from the dividend, add it to 22, then carry on: 220 / 51

Let's proceed to step 4:
If we divide 220 by 51, we get 4 and a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 134.0
The remainder is 16 after subtracting 204 from 220.
Take the next digit (5) from the dividend and append it to 16, then repeat: 165 / 51

Let's proceed to step 5:
The number 51 fits into 165 3 times, leaving a remainder of 12.
The next digit of our result is 3. 
Result so far: 1343.0
If we take 153 away from 165, 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.

Let's proceed to step 6:
51 goes into 120 2 times with a remainder of 18.
The next digit of our result is 2. 
Result so far: 1343.2
Deduct 102 from 120 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 7:
51 goes into 180 3 times with a remainder of 27.
The next digit of our result is 3. 
Result so far: 1343.23
Subtracting 153 from 180 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 8:
51 goes into 270 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 1343.235
If we subtract 255 from 270, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 9:
150 divided by 51 is 2 with a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 1343.2352
If we take 102 away from 150, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 10:
51 can be fit into 480 9 times, resulting in a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 1343.23529
If we take 459 away from 480, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 11:
If we divide 210 by 51, we get 4 and a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 1343.235294
The remainder is 6 after subtracting 204 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 12:
When dividing 60 by 51, we get 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 1343.2352941
Subtracting 51 from 60 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 13:
If we divide 90 by 51, we get 1 and a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 1343.23529411
Subtract 51 from 90 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The final outcome is 1343.23529411, with a leftover of 3.9e-08.
