We look at the division of 51261852 by 287 
We want to figure out the number of times 51261852 can be divided by 287.

Advancing to step 1:
If we divide 5 by 287, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 287

Step 2:
When dividing 51 by 287, we get 0 with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Bring next digit (2) of the dividend behind the 51 and repeat the process: 512 / 287

Step 3:
287 goes into 512 1 times with a remainder of 225.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 287 from 512 and we're left with 225.
Take the next digit (6) from the dividend and append it to 225, then repeat: 2256 / 287

Step 4:
The number 287 fits into 2256 7 times, leaving a remainder of 247.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtract 2009 from 2256 to get 247.
Grab the next digit (1) from the dividend, add it to 247, then carry on: 2471 / 287

Advancing to step 5:
2471 divided by 287 is 8 with a remainder of 175.
The next digit of our result is 8. 
Result so far: 178.0
If we take 2296 away from 2471, we end up with 175.
Fetch the next digit (8) from the dividend, attach it to 175 and continue: 1758 / 287

Going ahead to step 6:
287 goes into 1758 6 times with a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 1786.0
If we take 1722 away from 1758, we end up with 36.
Fetch the next digit (5) from the dividend, attach it to 36 and continue: 365 / 287

Let's proceed to step 7:
If we divide 365 by 287, we get 1 and a remainder of 78.
Write down 1 as next digit of the result. 
Result so far: 17861.0
If we take 287 away from 365, we end up with 78.
Include the next digit (2) from the dividend after 78, then repeat: 782 / 287

On to step 8:
If we divide 782 by 287, we get 2 and a remainder of 208.
Write down 2 as next digit of the result. 
Result so far: 178612.0
Subtract 574 from 782 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 9:
287 goes into 2080 7 times with a remainder of 71.
Put 7 as the next digit of the answer. 
Result so far: 178612.7
If we take 2009 away from 2080, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 10:
287 goes into 710 2 times with a remainder of 136.
Record the quotient 2 as the next digit in the result. 
Result so far: 178612.72
Deduct 574 from 710 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

On to step 11:
1360 divided by 287 is 4 with a remainder of 212.
Record the quotient 4 as the next digit in the result. 
Result so far: 178612.724
The remainder is 212 after subtracting 1148 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Going ahead to step 12:
If we divide 2120 by 287, we get 7 and a remainder of 111.
The next digit of our result is 7. 
Result so far: 178612.7247
Subtract 2009 from 2120 to get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Going ahead to step 13:
287 can be fit into 1110 3 times, resulting in a remainder of 249.
The next digit of our result is 3. 
Result so far: 178612.72473
Subtracting 861 from 1110 leaves us with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Moving on to step 14:
When dividing 2490 by 287, we get 8 with a remainder of 194.
Put 8 as the next digit of the answer. 
Result so far: 178612.724738
Deduct 2296 from 2490 and we're left with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Step 15:
287 goes into 1940 6 times with a remainder of 218.
The next digit of our result is 6. 
Result so far: 178612.7247386
If we take 1722 away from 1940, we end up with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Step 16:
When dividing 2180 by 287, we get 7 with a remainder of 171.
Put 7 as the next digit of the answer. 
Result so far: 178612.72473867
The remainder is 171 after subtracting 2009 from 2180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Our division results in 178612.72473867 with a remaining 1.71e-07.
