We're dividing 45572181 by 887 
Let's see how many times 887 fits into 45572181.

On to step 1:
If we divide 4 by 887, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 887

On to step 2:
The number 887 fits into 45 0 times, leaving a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Append the next digit (5) from the dividend to 45 and continue with: 455 / 887

On to step 3:
If we divide 455 by 887, we get 0 and a remainder of 455.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 455, we end up with 455.
Include the next digit (7) from the dividend after 455, then repeat: 4557 / 887

Advancing to step 4:
If we divide 4557 by 887, we get 5 and a remainder of 122.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 4435 from 4557 and we're left with 122.
Bring next digit (2) of the dividend behind the 122 and repeat the process: 1222 / 887

On to step 5:
887 goes into 1222 1 times with a remainder of 335.
Write down 1 as next digit of the result. 
Result so far: 51.0
Deduct 887 from 1222 and we're left with 335.
Fetch the next digit (1) from the dividend, attach it to 335 and continue: 3351 / 887

Advancing to step 6:
If we divide 3351 by 887, we get 3 and a remainder of 690.
Use 3 as the next digit of our solution. 
Result so far: 513.0
Subtracting 2661 from 3351 leaves us with 690.
Fetch the next digit (8) from the dividend, attach it to 690 and continue: 6908 / 887

Advancing to step 7:
6908 divided by 887 is 7 with a remainder of 699.
The next digit of our result is 7. 
Result so far: 5137.0
Deduct 6209 from 6908 and we're left with 699.
Include the next digit (1) from the dividend after 699, then repeat: 6991 / 887

Step 8:
The number 887 fits into 6991 7 times, leaving a remainder of 782.
Put 7 as the next digit of the answer. 
Result so far: 51377.0
The remainder is 782 after subtracting 6209 from 6991.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7820, and continue the process.

Moving on to step 9:
7820 divided by 887 is 8 with a remainder of 724.
The number 8 becomes the next digit in our result. 
Result so far: 51377.8
If we take 7096 away from 7820, we end up with 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

Let's proceed to step 10:
887 goes into 7240 8 times with a remainder of 144.
Put 8 as the next digit of the answer. 
Result so far: 51377.88
If we take 7096 away from 7240, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Our division results in 51377.88 with a remaining 0.144.
