We're dividing 45143738 by 503 
Our goal is to divide 45143738 by 503.

On to step 1:
503 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 503

Let's proceed to step 2:
503 goes into 45 0 times with a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Append the next digit (1) from the dividend to 45 and continue with: 451 / 503

Let's proceed to step 3:
When dividing 451 by 503, we get 0 with a remainder of 451.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 451, we end up with 451.
Append the next digit (4) from the dividend to 451 and continue with: 4514 / 503

Going ahead to step 4:
4514 divided by 503 is 8 with a remainder of 490.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 4024 from 4514 and we're left with 490.
Grab the next digit (3) from the dividend, add it to 490, then carry on: 4903 / 503

Let's proceed to step 5:
503 goes into 4903 9 times with a remainder of 376.
Write down 9 as next digit of the result. 
Result so far: 89.0
If we subtract 4527 from 4903, we get 376.
Include the next digit (7) from the dividend after 376, then repeat: 3767 / 503

On to step 6:
503 goes into 3767 7 times with a remainder of 246.
Write down 7 as next digit of the result. 
Result so far: 897.0
Subtract 3521 from 3767 to get 246.
Include the next digit (3) from the dividend after 246, then repeat: 2463 / 503

Advancing to step 7:
If we divide 2463 by 503, we get 4 and a remainder of 451.
The number 4 becomes the next digit in our result. 
Result so far: 8974.0
If we take 2012 away from 2463, we end up with 451.
Take the next digit (8) from the dividend and append it to 451, then repeat: 4518 / 503

Advancing to step 8:
The number 503 fits into 4518 8 times, leaving a remainder of 494.
Use 8 as the next digit of our solution. 
Result so far: 89748.0
Subtract 4024 from 4518 to get 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Let's proceed to step 9:
The number 503 fits into 4940 9 times, leaving a remainder of 413.
Use 9 as the next digit of our solution. 
Result so far: 89748.9
If we take 4527 away from 4940, we end up with 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

Step 10:
503 goes into 4130 8 times with a remainder of 106.
Use 8 as the next digit of our solution. 
Result so far: 89748.98
Subtracting 4024 from 4130 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Let's proceed to step 11:
When dividing 1060 by 503, we get 2 with a remainder of 54.
Write down 2 as next digit of the result. 
Result so far: 89748.982
Subtracting 1006 from 1060 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 12:
When dividing 540 by 503, we get 1 with a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 89748.9821
The remainder is 37 after subtracting 503 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 13:
The number 503 fits into 370 0 times, leaving a remainder of 370.
The next digit of our result is 0. 
Result so far: 89748.9821
If we take 0 away from 370, we end up with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Going ahead to step 14:
3700 divided by 503 is 7 with a remainder of 179.
The number 7 becomes the next digit in our result. 
Result so far: 89748.982107
Subtract 3521 from 3700 to get 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Advancing to step 15:
When dividing 1790 by 503, we get 3 with a remainder of 281.
Write down 3 as next digit of the result. 
Result so far: 89748.9821073
Deduct 1509 from 1790 and we're left with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Going ahead to step 16:
503 goes into 2810 5 times with a remainder of 295.
Record the quotient 5 as the next digit in the result. 
Result so far: 89748.98210735
Deduct 2515 from 2810 and we're left with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

The quotient of the division is 89748.98210735, and the remainder is 2.95e-07.
