We divide 645281 by 51
We're looking to find how many times 51 goes into 645281.

Moving on to step 1:
If we divide 6 by 51, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 51

On to step 2:
The number 51 fits into 64 1 times, leaving a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 51 from 64 and we're left with 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 51

Advancing to step 3:
51 goes into 135 2 times with a remainder of 33.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 102 from 135 leaves us with 33.
Grab the next digit (2) from the dividend, add it to 33, then carry on: 332 / 51

Going ahead to step 4:
51 can be fit into 332 6 times, resulting in a remainder of 26.
Write down 6 as next digit of the result. 
Result so far: 126.0
If we subtract 306 from 332, we get 26.
Bring next digit (8) of the dividend behind the 26 and repeat the process: 268 / 51

Going ahead to step 5:
If we divide 268 by 51, we get 5 and a remainder of 13.
Use 5 as the next digit of our solution. 
Result so far: 1265.0
Subtracting 255 from 268 leaves us with 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 51

Advancing to step 6:
If we divide 131 by 51, we get 2 and a remainder of 29.
The number 2 becomes the next digit in our result. 
Result so far: 12652.0
If we subtract 102 from 131, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 7:
If we divide 290 by 51, we get 5 and a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 12652.5
Deduct 255 from 290 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.

Moving on to step 8:
350 divided by 51 is 6 with a remainder of 44.
The next digit of our result is 6. 
Result so far: 12652.56
Subtracting 306 from 350 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 9:
When dividing 440 by 51, we get 8 with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 12652.568
Subtracting 408 from 440 leaves us 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 10:
51 goes into 320 6 times with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 12652.5686
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.

Advancing to step 11:
51 can be fit into 140 2 times, resulting in a remainder of 38.
The next digit of our result is 2. 
Result so far: 12652.56862
Deduct 102 from 140 and we're left 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.

Going ahead to step 12:
If we divide 380 by 51, we get 7 and a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 12652.568627
If we subtract 357 from 380, we get 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 13:
When dividing 230 by 51, we get 4 with a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 12652.5686274
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.

Let's proceed to step 14:
The number 51 fits into 260 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 12652.56862745
Subtract 255 from 260 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 12652.56862745, with a leftover of 5e-09.
