We divide 8712189 by 224
We want to figure out the number of times 8712189 can be divided by 224.

Advancing to step 1:
If we divide 8 by 224, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 224

On to step 2:
If we divide 87 by 224, we get 0 and a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Append the next digit (1) from the dividend to 87 and continue with: 871 / 224

Let's proceed to step 3:
224 can be fit into 871 3 times, resulting in a remainder of 199.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 672 from 871 and we're left with 199.
Append the next digit (2) from the dividend to 199 and continue with: 1992 / 224

Step 4:
The number 224 fits into 1992 8 times, leaving a remainder of 200.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
If we subtract 1792 from 1992, we get 200.
Bring next digit (1) of the dividend behind the 200 and repeat the process: 2001 / 224

Going ahead to step 5:
The number 224 fits into 2001 8 times, leaving a remainder of 209.
Put 8 as the next digit of the answer. 
Result so far: 388.0
The remainder is 209 after subtracting 1792 from 2001.
Bring next digit (8) of the dividend behind the 209 and repeat the process: 2098 / 224

Step 6:
224 goes into 2098 9 times with a remainder of 82.
Record the quotient 9 as the next digit in the result. 
Result so far: 3889.0
If we take 2016 away from 2098, we end up with 82.
Fetch the next digit (9) from the dividend, attach it to 82 and continue: 829 / 224

Let's proceed to step 7:
224 can be fit into 829 3 times, resulting in a remainder of 157.
The number 3 becomes the next digit in our result. 
Result so far: 38893.0
Subtract 672 from 829 to get 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Let's proceed to step 8:
If we divide 1570 by 224, we get 7 and a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 38893.7
The remainder is 2 after subtracting 1568 from 1570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 9:
If we divide 20 by 224, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 38893.7
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
The number 224 fits into 200 0 times, leaving a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 38893.7
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final result is 38893.7 with a remainder of 0.02.
