396665 ÷ 51 
We're looking to find how many times 51 goes into 396665.

On to step 1:
If we divide 3 by 51, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 51

On to step 2:
51 can be fit into 39 0 times, resulting in a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Grab the next digit (6) from the dividend, add it to 39, then carry on: 396 / 51

Step 3:
When dividing 396 by 51, we get 7 with a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 357 away from 396, we end up with 39.
Append the next digit (6) from the dividend to 39 and continue with: 396 / 51

On to step 4:
396 divided by 51 is 7 with a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
Subtracting 357 from 396 leaves us with 39.
Include the next digit (6) from the dividend after 39, then repeat: 396 / 51

Let's proceed to step 5:
51 can be fit into 396 7 times, resulting in a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 777.0
If we subtract 357 from 396, we get 39.
Append the next digit (5) from the dividend to 39 and continue with: 395 / 51

Let's proceed to step 6:
If we divide 395 by 51, we get 7 and a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 7777.0
Subtract 357 from 395 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 7:
The number 51 fits into 380 7 times, leaving a remainder of 23.
The next digit of our result is 7. 
Result so far: 7777.7
Subtract 357 from 380 to 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.

On to step 8:
51 goes into 230 4 times with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 7777.74
The remainder is 26 after subtracting 204 from 230.
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 9:
When dividing 260 by 51, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 7777.745
If we subtract 255 from 260, we 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.

Let's proceed to step 10:
51 goes into 50 0 times with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 7777.745
Subtract 0 from 50 to 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.

Step 11:
When dividing 500 by 51, we get 9 with a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 7777.74509
Subtract 459 from 500 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 12:
410 divided by 51 is 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 7777.745098
If we subtract 408 from 410, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 13:
When dividing 20 by 51, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 7777.745098
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 14:
If we divide 200 by 51, we get 3 and a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 7777.74509803
Deduct 153 from 200 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The quotient of the division is 7777.74509803, and the remainder is 4.7e-08.
