656386 divided by 51 
We want to figure out the number of times 656386 can be divided by 51.

On to step 1:
The number 51 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 51

On to step 2:
When dividing 65 by 51, we get 1 with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 51 from 65 leaves us with 14.
Bring next digit (6) of the dividend behind the 14 and repeat the process: 146 / 51

Step 3:
146 divided by 51 is 2 with a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 102 from 146 and we're left with 44.
Take the next digit (3) from the dividend and append it to 44, then repeat: 443 / 51

Advancing to step 4:
If we divide 443 by 51, we get 8 and a remainder of 35.
Put 8 as the next digit of the answer. 
Result so far: 128.0
Subtracting 408 from 443 leaves us with 35.
Take the next digit (8) from the dividend and append it to 35, then repeat: 358 / 51

Moving on to step 5:
358 divided by 51 is 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 1287.0
If we subtract 357 from 358, we get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 51

Step 6:
51 can be fit into 16 0 times, resulting in a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 12870.0
Deduct 0 from 16 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
The number 51 fits into 160 3 times, leaving a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 12870.3
If we subtract 153 from 160, we 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.

Let's proceed to step 8:
70 divided by 51 is 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 12870.31
If we subtract 51 from 70, we get 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 9:
When dividing 190 by 51, we get 3 with a remainder of 37.
The next digit of our result is 3. 
Result so far: 12870.313
Subtract 153 from 190 to get 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 10:
The number 51 fits into 370 7 times, leaving a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 12870.3137
The remainder is 13 after subtracting 357 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 11:
When dividing 130 by 51, we get 2 with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 12870.31372
Subtracting 102 from 130 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 12:
The number 51 fits into 280 5 times, leaving a remainder of 25.
The next digit of our result is 5. 
Result so far: 12870.313725
Subtract 255 from 280 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 13:
51 can be fit into 250 4 times, resulting in a remainder of 46.
The next digit of our result is 4. 
Result so far: 12870.3137254
Deduct 204 from 250 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 14:
When dividing 460 by 51, we get 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 12870.31372549
Deduct 459 from 460 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 12870.31372549 and a remainder of 1e-09.
