688233 ÷ 51 
Our goal is to divide 688233 by 51.

Step 1:
If we divide 6 by 51, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 51

Moving on to step 2:
51 goes into 68 1 times with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 17 after subtracting 51 from 68.
Bring next digit (8) of the dividend behind the 17 and repeat the process: 178 / 51

Step 3:
178 divided by 51 is 3 with a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 153 from 178 and we're left with 25.
Bring next digit (2) of the dividend behind the 25 and repeat the process: 252 / 51

Step 4:
The number 51 fits into 252 4 times, leaving a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 134.0
If we subtract 204 from 252, we get 48.
Take the next digit (3) from the dividend and append it to 48, then repeat: 483 / 51

On to step 5:
If we divide 483 by 51, we get 9 and a remainder of 24.
Record the quotient 9 as the next digit in the result. 
Result so far: 1349.0
If we take 459 away from 483, we end up with 24.
Append the next digit (3) from the dividend to 24 and continue with: 243 / 51

Let's proceed to step 6:
243 divided by 51 is 4 with a remainder of 39.
Record the quotient 4 as the next digit in the result. 
Result so far: 13494.0
If we subtract 204 from 243, we 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.

Step 7:
If we divide 390 by 51, we get 7 and a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 13494.7
Subtract 357 from 390 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 8:
When dividing 330 by 51, we get 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 13494.76
Deduct 306 from 330 and we're left 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.

Advancing to 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: 13494.764
If we take 204 away from 240, we end up with 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:
The number 51 fits into 360 7 times, leaving a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 13494.7647
Deduct 357 from 360 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 11:
When dividing 30 by 51, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 13494.7647
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 12:
The number 51 fits into 300 5 times, leaving a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 13494.764705
The remainder is 45 after subtracting 255 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 13:
51 can be fit into 450 8 times, resulting in a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 13494.7647058
Deduct 408 from 450 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 14:
If we divide 420 by 51, we get 8 and a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 13494.76470588
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 result is 13494.76470588 with a remainder of 1.2e-08.
