We're dividing 51658944 by 503 
Our goal is to divide 51658944 by 503.

Moving on to step 1:
If we divide 5 by 503, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 503

Moving on to step 2:
The number 503 fits into 51 0 times, leaving a remainder of 51.
Write down 0 as next digit of the 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 / 503

Going ahead to step 3:
When dividing 516 by 503, we get 1 with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 503 from 516, we get 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 503

Advancing to step 4:
503 goes into 135 0 times with a remainder of 135.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 135 leaves us with 135.
Fetch the next digit (8) from the dividend, attach it to 135 and continue: 1358 / 503

Moving on to step 5:
If we divide 1358 by 503, we get 2 and a remainder of 352.
Write down 2 as next digit of the result. 
Result so far: 102.0
If we subtract 1006 from 1358, we get 352.
Append the next digit (9) from the dividend to 352 and continue with: 3529 / 503

Moving on to step 6:
The number 503 fits into 3529 7 times, leaving a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 1027.0
Deduct 3521 from 3529 and we're left with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 503

Advancing to step 7:
503 can be fit into 84 0 times, resulting in a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 10270.0
If we take 0 away from 84, we end up with 84.
Append the next digit (4) from the dividend to 84 and continue with: 844 / 503

Advancing to step 8:
844 divided by 503 is 1 with a remainder of 341.
Record the quotient 1 as the next digit in the result. 
Result so far: 102701.0
If we subtract 503 from 844, we get 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Let's proceed to step 9:
3410 divided by 503 is 6 with a remainder of 392.
Put 6 as the next digit of the answer. 
Result so far: 102701.6
Deduct 3018 from 3410 and we're left with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Going ahead to step 10:
3920 divided by 503 is 7 with a remainder of 399.
Write down 7 as next digit of the result. 
Result so far: 102701.67
If we subtract 3521 from 3920, we get 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

Moving on to step 11:
The number 503 fits into 3990 7 times, leaving a remainder of 469.
Record the quotient 7 as the next digit in the result. 
Result so far: 102701.677
Deduct 3521 from 3990 and we're left with 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

The final outcome is 102701.677, with a leftover of 0.0469.
