Let's divide 726846 by 51
We're looking to find how many times 51 goes into 726846.

Step 1:
When dividing 7 by 51, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 51

On to step 2:
If we divide 72 by 51, we get 1 and a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 51 away from 72, we end up with 21.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 51

Let's proceed to step 3:
51 goes into 216 4 times with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we take 204 away from 216, we end up with 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 51

Advancing to step 4:
When dividing 128 by 51, we get 2 with a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 142.0
If we take 102 away from 128, we end up with 26.
Take the next digit (4) from the dividend and append it to 26, then repeat: 264 / 51

Step 5:
51 can be fit into 264 5 times, resulting in a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 1425.0
If we take 255 away from 264, we end up with 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 51

Advancing to step 6:
51 can be fit into 96 1 times, resulting in a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 14251.0
If we subtract 51 from 96, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 7:
51 can be fit into 450 8 times, resulting in a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 14251.8
Deduct 408 from 450 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 8:
When dividing 420 by 51, we get 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 14251.88
If we take 408 away from 420, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 14251.88, and the remainder is 0.012.
