690876 divided by 51 
Our goal is to divide 690876 by 51.

Going ahead to step 1:
The number 51 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 51

Let's proceed to step 2:
If we divide 69 by 51, we get 1 and a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 51 from 69 leaves us with 18.
Bring next digit (0) of the dividend behind the 18 and repeat the process: 180 / 51

Step 3:
The number 51 fits into 180 3 times, leaving a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we subtract 153 from 180, we get 27.
Grab the next digit (8) from the dividend, add it to 27, then carry on: 278 / 51

Moving on to step 4:
278 divided by 51 is 5 with a remainder of 23.
The number 5 becomes the next digit in our result. 
Result so far: 135.0
Subtracting 255 from 278 leaves us with 23.
Take the next digit (7) from the dividend and append it to 23, then repeat: 237 / 51

Let's proceed to step 5:
51 goes into 237 4 times with a remainder of 33.
Use 4 as the next digit of our solution. 
Result so far: 1354.0
If we subtract 204 from 237, we get 33.
Grab the next digit (6) from the dividend, add it to 33, then carry on: 336 / 51

Step 6:
If we divide 336 by 51, we get 6 and a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 13546.0
If we take 306 away from 336, we end up 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 7:
If we divide 300 by 51, we get 5 and a remainder of 45.
The next digit of our result is 5. 
Result so far: 13546.5
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.

Moving on to step 8:
The number 51 fits into 450 8 times, leaving a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 13546.58
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.

Moving on to step 9:
51 goes into 420 8 times with a remainder of 12.
The next digit of our result is 8. 
Result so far: 13546.588
Subtract 408 from 420 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 13546.588 and a remainder of 0.0012.
