We look at the division of 45443741 by 503 
Let's see how many times 503 fits into 45443741.

Advancing to step 1:
503 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 503

Going ahead to step 2:
If we divide 45 by 503, we get 0 and a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Append the next digit (4) from the dividend to 45 and continue with: 454 / 503

On to step 3:
503 can be fit into 454 0 times, resulting in a remainder of 454.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 454, we end up with 454.
Take the next digit (4) from the dividend and append it to 454, then repeat: 4544 / 503

Going ahead to step 4:
When dividing 4544 by 503, we get 9 with a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 4527 away from 4544, we end up with 17.
Fetch the next digit (3) from the dividend, attach it to 17 and continue: 173 / 503

Step 5:
503 can be fit into 173 0 times, resulting in a remainder of 173.
The next digit of our result is 0. 
Result so far: 90.0
If we take 0 away from 173, we end up with 173.
Grab the next digit (7) from the dividend, add it to 173, then carry on: 1737 / 503

Moving on to step 6:
1737 divided by 503 is 3 with a remainder of 228.
The next digit of our result is 3. 
Result so far: 903.0
The remainder is 228 after subtracting 1509 from 1737.
Append the next digit (4) from the dividend to 228 and continue with: 2284 / 503

On to step 7:
When dividing 2284 by 503, we get 4 with a remainder of 272.
Use 4 as the next digit of our solution. 
Result so far: 9034.0
Subtract 2012 from 2284 to get 272.
Append the next digit (1) from the dividend to 272 and continue with: 2721 / 503

Let's proceed to step 8:
The number 503 fits into 2721 5 times, leaving a remainder of 206.
The number 5 becomes the next digit in our result. 
Result so far: 90345.0
Subtracting 2515 from 2721 leaves us with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Step 9:
The number 503 fits into 2060 4 times, leaving a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 90345.4
Subtracting 2012 from 2060 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 10:
503 can be fit into 480 0 times, resulting in a remainder of 480.
The next digit of our result is 0. 
Result so far: 90345.4
Subtracting 0 from 480 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 11:
503 can be fit into 4800 9 times, resulting in a remainder of 273.
Record the quotient 9 as the next digit in the result. 
Result so far: 90345.409
If we subtract 4527 from 4800, we get 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Going ahead to step 12:
If we divide 2730 by 503, we get 5 and a remainder of 215.
The next digit of our result is 5. 
Result so far: 90345.4095
Subtracting 2515 from 2730 leaves us with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Advancing to step 13:
2150 divided by 503 is 4 with a remainder of 138.
Put 4 as the next digit of the answer. 
Result so far: 90345.40954
If we subtract 2012 from 2150, we get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

On to step 14:
503 can be fit into 1380 2 times, resulting in a remainder of 374.
Write down 2 as next digit of the result. 
Result so far: 90345.409542
If we subtract 1006 from 1380, we get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Advancing to step 15:
If we divide 3740 by 503, we get 7 and a remainder of 219.
Record the quotient 7 as the next digit in the result. 
Result so far: 90345.4095427
If we take 3521 away from 3740, we end up with 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Advancing to step 16:
503 goes into 2190 4 times with a remainder of 178.
The number 4 becomes the next digit in our result. 
Result so far: 90345.40954274
If we take 2012 away from 2190, we end up with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

In conclusion, the division gives 90345.40954274 with a balance of 1.78e-07.
