We're dividing 45596503 by 172 
We want to divide 45596503 by 172.

Step 1:
If we divide 4 by 172, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 172

Moving on to step 2:
172 can be fit into 45 0 times, resulting in a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Fetch the next digit (5) from the dividend, attach it to 45 and continue: 455 / 172

Moving on to step 3:
If we divide 455 by 172, we get 2 and a remainder of 111.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 344 from 455, we get 111.
Take the next digit (9) from the dividend and append it to 111, then repeat: 1119 / 172

Advancing to step 4:
If we divide 1119 by 172, we get 6 and a remainder of 87.
Use 6 as the next digit of our solution. 
Result so far: 26.0
Subtract 1032 from 1119 to get 87.
Bring next digit (6) of the dividend behind the 87 and repeat the process: 876 / 172

Advancing to step 5:
If we divide 876 by 172, we get 5 and a remainder of 16.
Use 5 as the next digit of our solution. 
Result so far: 265.0
Deduct 860 from 876 and we're left with 16.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 172

Let's proceed to step 6:
The number 172 fits into 165 0 times, leaving a remainder of 165.
Record the quotient 0 as the next digit in the result. 
Result so far: 2650.0
If we take 0 away from 165, we end up with 165.
Grab the next digit (0) from the dividend, add it to 165, then carry on: 1650 / 172

Going ahead to step 7:
172 goes into 1650 9 times with a remainder of 102.
Write down 9 as next digit of the result. 
Result so far: 26509.0
If we subtract 1548 from 1650, we get 102.
Fetch the next digit (3) from the dividend, attach it to 102 and continue: 1023 / 172

Let's proceed to step 8:
If we divide 1023 by 172, we get 5 and a remainder of 163.
Use 5 as the next digit of our solution. 
Result so far: 265095.0
If we take 860 away from 1023, we end up with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Advancing to step 9:
The number 172 fits into 1630 9 times, leaving a remainder of 82.
The number 9 becomes the next digit in our result. 
Result so far: 265095.9
Deduct 1548 from 1630 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 10:
172 can be fit into 820 4 times, resulting in a remainder of 132.
Record the quotient 4 as the next digit in the result. 
Result so far: 265095.94
Subtracting 688 from 820 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 11:
The number 172 fits into 1320 7 times, leaving a remainder of 116.
Put 7 as the next digit of the answer. 
Result so far: 265095.947
If we subtract 1204 from 1320, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 12:
The number 172 fits into 1160 6 times, leaving a remainder of 128.
Write down 6 as next digit of the result. 
Result so far: 265095.9476
If we subtract 1032 from 1160, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 13:
172 can be fit into 1280 7 times, resulting in a remainder of 76.
Use 7 as the next digit of our solution. 
Result so far: 265095.94767
If we take 1204 away from 1280, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 14:
172 goes into 760 4 times with a remainder of 72.
Write down 4 as next digit of the result. 
Result so far: 265095.947674
Subtracting 688 from 760 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 15:
The number 172 fits into 720 4 times, leaving a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 265095.9476744
If we take 688 away from 720, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 265095.9476744, and the remainder is 3.2e-07.
