We divide 645862 by 51
We're looking to find how many times 51 goes into 645862.

Let's proceed to step 1:
The number 51 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
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

Step 2:
The number 51 fits into 64 1 times, leaving a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 51 from 64 to get 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 51

Advancing to step 3:
51 goes into 135 2 times with a remainder of 33.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 102 from 135, we get 33.
Include the next digit (8) from the dividend after 33, then repeat: 338 / 51

On to step 4:
338 divided by 51 is 6 with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 126.0
Subtract 306 from 338 to get 32.
Bring next digit (6) of the dividend behind the 32 and repeat the process: 326 / 51

Let's proceed to step 5:
51 can be fit into 326 6 times, resulting in a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 1266.0
Subtract 306 from 326 to get 20.
Bring next digit (2) of the dividend behind the 20 and repeat the process: 202 / 51

On to step 6:
If we divide 202 by 51, we get 3 and a remainder of 49.
The number 3 becomes the next digit in our result. 
Result so far: 12663.0
Subtracting 153 from 202 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 7:
If we divide 490 by 51, we get 9 and a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 12663.9
The remainder is 31 after subtracting 459 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 8:
310 divided by 51 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 12663.96
If we subtract 306 from 310, we get 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 9:
51 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 12663.96
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.

Moving on to step 10:
400 divided by 51 is 7 with a remainder of 43.
Write down 7 as next digit of the result. 
Result so far: 12663.9607
Subtracting 357 from 400 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 11:
The number 51 fits into 430 8 times, leaving a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 12663.96078
The remainder is 22 after subtracting 408 from 430.
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 12:
220 divided by 51 is 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 12663.960784
Subtract 204 from 220 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
The number 51 fits into 160 3 times, leaving a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 12663.9607843
If we take 153 away from 160, we end up with 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 14:
51 can be fit into 70 1 times, resulting in a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 12663.96078431
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.

The final result is 12663.96078431 with a remainder of 1.9e-08.
