Let's divide 51456001 by 851
Let's see how many times 851 fits into 51456001.

On to step 1:
If we divide 5 by 851, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 851

Advancing to step 2:
51 divided by 851 is 0 with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Bring next digit (4) of the dividend behind the 51 and repeat the process: 514 / 851

Moving on to step 3:
851 goes into 514 0 times with a remainder of 514.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 514 and we're left with 514.
Grab the next digit (5) from the dividend, add it to 514, then carry on: 5145 / 851

Going ahead to step 4:
When dividing 5145 by 851, we get 6 with a remainder of 39.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 5106 from 5145, we get 39.
Take the next digit (6) from the dividend and append it to 39, then repeat: 396 / 851

Step 5:
851 goes into 396 0 times with a remainder of 396.
Put 0 as the next digit of the answer. 
Result so far: 60.0
Subtracting 0 from 396 leaves us with 396.
Fetch the next digit (0) from the dividend, attach it to 396 and continue: 3960 / 851

Going ahead to step 6:
The number 851 fits into 3960 4 times, leaving a remainder of 556.
The number 4 becomes the next digit in our result. 
Result so far: 604.0
Subtract 3404 from 3960 to get 556.
Fetch the next digit (0) from the dividend, attach it to 556 and continue: 5560 / 851

Let's proceed to step 7:
When dividing 5560 by 851, we get 6 with a remainder of 454.
The next digit of our result is 6. 
Result so far: 6046.0
The remainder is 454 after subtracting 5106 from 5560.
Include the next digit (1) from the dividend after 454, then repeat: 4541 / 851

Moving on to step 8:
4541 divided by 851 is 5 with a remainder of 286.
Write down 5 as next digit of the result. 
Result so far: 60465.0
Deduct 4255 from 4541 and we're left with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Moving on to step 9:
The number 851 fits into 2860 3 times, leaving a remainder of 307.
Record the quotient 3 as the next digit in the result. 
Result so far: 60465.3
The remainder is 307 after subtracting 2553 from 2860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Going ahead to step 10:
The number 851 fits into 3070 3 times, leaving a remainder of 517.
The number 3 becomes the next digit in our result. 
Result so far: 60465.33
If we take 2553 away from 3070, we end up with 517.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

Our division results in 60465.33 with a remaining 0.517.
