445399 ÷ 51 
We want to divide 445399 by 51.

Moving on to step 1:
The number 51 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 51

Moving on to step 2:
44 divided by 51 is 0 with a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 44 and we're left with 44.
Fetch the next digit (5) from the dividend, attach it to 44 and continue: 445 / 51

Moving on to step 3:
51 can be fit into 445 8 times, resulting in a remainder of 37.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 408 from 445 to get 37.
Include the next digit (3) from the dividend after 37, then repeat: 373 / 51

Going ahead to step 4:
The number 51 fits into 373 7 times, leaving a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 87.0
Subtract 357 from 373 to get 16.
Fetch the next digit (9) from the dividend, attach it to 16 and continue: 169 / 51

Going ahead to step 5:
The number 51 fits into 169 3 times, leaving a remainder of 16.
The next digit of our result is 3. 
Result so far: 873.0
Subtracting 153 from 169 leaves us with 16.
Append the next digit (9) from the dividend to 16 and continue with: 169 / 51

Step 6:
51 can be fit into 169 3 times, resulting in a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 8733.0
The remainder is 16 after subtracting 153 from 169.
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:
When dividing 160 by 51, we get 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 8733.3
Subtracting 153 from 160 leaves us 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.

Advancing to step 8:
51 goes into 70 1 times with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 8733.31
Subtract 51 from 70 to 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.

Let's proceed to step 9:
The number 51 fits into 190 3 times, leaving a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 8733.313
The remainder is 37 after subtracting 153 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 10:
51 can be fit into 370 7 times, resulting in a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 8733.3137
If we take 357 away from 370, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 11:
The number 51 fits into 130 2 times, leaving a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 8733.31372
If we take 102 away from 130, we end up 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.

Step 12:
When dividing 280 by 51, we get 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 8733.313725
Deduct 255 from 280 and we're left with 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:
250 divided by 51 is 4 with a remainder of 46.
The next digit of our result is 4. 
Result so far: 8733.3137254
Subtract 204 from 250 to get 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: 8733.31372549
Subtracting 459 from 460 leaves us 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 8733.31372549 and a remainder of 1e-09.
