Let's divide 687566 by 51
We want to figure out the number of times 687566 can be divided by 51.

Let's proceed to step 1:
51 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 51

Moving on to step 2:
68 divided by 51 is 1 with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 51 from 68 and we're left with 17.
Fetch the next digit (7) from the dividend, attach it to 17 and continue: 177 / 51

Advancing to step 3:
177 divided by 51 is 3 with a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we take 153 away from 177, we end up with 24.
Take the next digit (5) from the dividend and append it to 24, then repeat: 245 / 51

Let's proceed to step 4:
If we divide 245 by 51, we get 4 and a remainder of 41.
The next digit of our result is 4. 
Result so far: 134.0
Deduct 204 from 245 and we're left with 41.
Take the next digit (6) from the dividend and append it to 41, then repeat: 416 / 51

Moving on to step 5:
The number 51 fits into 416 8 times, leaving a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 1348.0
If we subtract 408 from 416, we get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 51

On to step 6:
If we divide 86 by 51, we get 1 and a remainder of 35.
Record the quotient 1 as the next digit in the result. 
Result so far: 13481.0
Deduct 51 from 86 and we're left 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.

Advancing to step 7:
When dividing 350 by 51, we get 6 with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 13481.6
The remainder is 44 after subtracting 306 from 350.
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 8:
440 divided by 51 is 8 with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 13481.68
Deduct 408 from 440 and we're left 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.

Step 9:
51 goes into 320 6 times with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 13481.686
Subtracting 306 from 320 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 10:
51 can be fit into 140 2 times, resulting in a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 13481.6862
Subtracting 102 from 140 leaves us 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.

Moving on to step 11:
51 goes into 380 7 times with a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 13481.68627
Subtracting 357 from 380 leaves us with 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 12:
When dividing 230 by 51, we get 4 with a remainder of 26.
The next digit of our result is 4. 
Result so far: 13481.686274
If we take 204 away from 230, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 13:
When dividing 260 by 51, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 13481.6862745
Deduct 255 from 260 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 14:
If we divide 50 by 51, we get 0 and a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 13481.6862745
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 13481.6862745 with a remaining 5e-08.
