We divide 45172855 by 209
We want to divide 45172855 by 209.

Advancing to step 1:
209 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 209

Step 2:
209 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
If we take 0 away from 45, we end up with 45.
Bring next digit (1) of the dividend behind the 45 and repeat the process: 451 / 209

Moving on to step 3:
If we divide 451 by 209, we get 2 and a remainder of 33.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 418 from 451 and we're left with 33.
Include the next digit (7) from the dividend after 33, then repeat: 337 / 209

On to step 4:
The number 209 fits into 337 1 times, leaving a remainder of 128.
The next digit of our result is 1. 
Result so far: 21.0
The remainder is 128 after subtracting 209 from 337.
Fetch the next digit (2) from the dividend, attach it to 128 and continue: 1282 / 209

Let's proceed to step 5:
1282 divided by 209 is 6 with a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 216.0
Subtract 1254 from 1282 to get 28.
Grab the next digit (8) from the dividend, add it to 28, then carry on: 288 / 209

Step 6:
If we divide 288 by 209, we get 1 and a remainder of 79.
Write down 1 as next digit of the result. 
Result so far: 2161.0
If we take 209 away from 288, we end up with 79.
Take the next digit (5) from the dividend and append it to 79, then repeat: 795 / 209

Step 7:
209 goes into 795 3 times with a remainder of 168.
The number 3 becomes the next digit in our result. 
Result so far: 21613.0
Subtract 627 from 795 to get 168.
Bring next digit (5) of the dividend behind the 168 and repeat the process: 1685 / 209

On to step 8:
1685 divided by 209 is 8 with a remainder of 13.
Record the quotient 8 as the next digit in the result. 
Result so far: 216138.0
If we take 1672 away from 1685, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 9:
209 can be fit into 130 0 times, resulting in a remainder of 130.
Put 0 as the next digit of the answer. 
Result so far: 216138.0
Deduct 0 from 130 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 10:
1300 divided by 209 is 6 with a remainder of 46.
The number 6 becomes the next digit in our result. 
Result so far: 216138.06
Subtract 1254 from 1300 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 11:
209 goes into 460 2 times with a remainder of 42.
Use 2 as the next digit of our solution. 
Result so far: 216138.062
If we subtract 418 from 460, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 12:
420 divided by 209 is 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 216138.0622
Subtracting 418 from 420 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 216138.0622 and a remainder of 2e-05.
