687025 divided by 51 
Let's see how many times 51 fits into 687025.

Going ahead to step 1:
If we divide 6 by 51, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 51

Going ahead to step 2:
The number 51 fits into 68 1 times, leaving a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 51 away from 68, we end up with 17.
Bring next digit (7) of the dividend behind the 17 and repeat the process: 177 / 51

On to step 3:
The number 51 fits into 177 3 times, leaving a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 153 from 177 and we're left with 24.
Grab the next digit (0) from the dividend, add it to 24, then carry on: 240 / 51

Step 4:
51 can be fit into 240 4 times, resulting in a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 134.0
The remainder is 36 after subtracting 204 from 240.
Append the next digit (2) from the dividend to 36 and continue with: 362 / 51

Moving on to step 5:
When dividing 362 by 51, we get 7 with a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 1347.0
Subtract 357 from 362 to get 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 51

Let's proceed to step 6:
55 divided by 51 is 1 with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 13471.0
Deduct 51 from 55 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
If we divide 40 by 51, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 13471.0
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
51 goes into 400 7 times with a remainder of 43.
The next digit of our result is 7. 
Result so far: 13471.07
The remainder is 43 after subtracting 357 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 9:
When dividing 430 by 51, we get 8 with a remainder of 22.
The next digit of our result is 8. 
Result so far: 13471.078
Deduct 408 from 430 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 10:
51 can be fit into 220 4 times, resulting in a remainder of 16.
The next digit of our result is 4. 
Result so far: 13471.0784
The remainder is 16 after subtracting 204 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
51 goes into 160 3 times with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 13471.07843
Subtract 153 from 160 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 12:
The number 51 fits into 70 1 times, leaving a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 13471.078431
If we take 51 away from 70, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 13:
190 divided by 51 is 3 with a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 13471.0784313
Deduct 153 from 190 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 14:
370 divided by 51 is 7 with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 13471.07843137
Subtract 357 from 370 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final result is 13471.07843137 with a remainder of 1.3e-08.
