We look at the division of 51607757 by 903 
We're looking to find how many times 903 goes into 51607757.

On to step 1:
903 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 903

Advancing to step 2:
51 divided by 903 is 0 with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Include the next digit (6) from the dividend after 51, then repeat: 516 / 903

Going ahead to step 3:
903 goes into 516 0 times with a remainder of 516.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 516, we get 516.
Append the next digit (0) from the dividend to 516 and continue with: 5160 / 903

Advancing to step 4:
903 can be fit into 5160 5 times, resulting in a remainder of 645.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 4515 from 5160 to get 645.
Append the next digit (7) from the dividend to 645 and continue with: 6457 / 903

Going ahead to step 5:
When dividing 6457 by 903, we get 7 with a remainder of 136.
The next digit of our result is 7. 
Result so far: 57.0
Subtract 6321 from 6457 to get 136.
Take the next digit (7) from the dividend and append it to 136, then repeat: 1367 / 903

Let's proceed to step 6:
If we divide 1367 by 903, we get 1 and a remainder of 464.
Use 1 as the next digit of our solution. 
Result so far: 571.0
Deduct 903 from 1367 and we're left with 464.
Include the next digit (5) from the dividend after 464, then repeat: 4645 / 903

Let's proceed to step 7:
If we divide 4645 by 903, we get 5 and a remainder of 130.
The next digit of our result is 5. 
Result so far: 5715.0
The remainder is 130 after subtracting 4515 from 4645.
Grab the next digit (7) from the dividend, add it to 130, then carry on: 1307 / 903

Advancing to step 8:
When dividing 1307 by 903, we get 1 with a remainder of 404.
Use 1 as the next digit of our solution. 
Result so far: 57151.0
The remainder is 404 after subtracting 903 from 1307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Advancing to step 9:
The number 903 fits into 4040 4 times, leaving a remainder of 428.
Record the quotient 4 as the next digit in the result. 
Result so far: 57151.4
The remainder is 428 after subtracting 3612 from 4040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Going ahead to step 10:
4280 divided by 903 is 4 with a remainder of 668.
The number 4 becomes the next digit in our result. 
Result so far: 57151.44
The remainder is 668 after subtracting 3612 from 4280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

The final result is 57151.44 with a remainder of 0.668.
