Subtract 1782 from 2227 to get 445.
Fetch the next digit (1) from the dividend, attach it to 445 and continue: 4451 / 891

Step 6:
When dividing 4451 by 891, we get 4 with a remainder of 887.
Record the quotient 4 as the next digit in the result. 
Result so far: 624.0
Subtracting 3564 from 4451 leaves us with 887.
Append the next digit (6) from the dividend to 887 and continue with: 8876 / 891

Let's proceed to step 7:
When dividing 8876 by 891, we get 9 with a remainder of 857.
The number 9 becomes the next digit in our result. 
Result so far: 6249.0
The remainder is 857 after subtracting 8019 from 8876.
Append the next digit (1) from the dividend to 857 and continue with: 8571 / 891

On to step 8:
8571 divided by 891 is 9 with a remainder of 552.
Record the quotient 9 as the next digit in the result. 
Result so far: 62499.0
Subtract 8019 from 8571 to get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Going ahead to step 9:
891 goes into 5520 6 times with a remainder of 174.
The number 6 becomes the next digit in our result. 
Result so far: 62499.6
Subtracting 5346 from 5520 leaves us with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Moving on to step 10:
If we divide 1740 by 891, we get 1 and a remainder of 849.
Record the quotient 1 as the next digit in the result. 
Result so far: 62499.61
Subtract 891 from 1740 to get 849.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8490, and continue the process.

Going ahead to step 11:
8490 divided by 891 is 9 with a remainder of 471.
Write down 9 as next digit of the result. 
Result so far: 62499.619
Subtract 8019 from 8490 to get 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

Going ahead to step 12:
If we divide 4710 by 891, we get 5 and a remainder of 255.
The number 5 becomes the next digit in our result. 
Result so far: 62499.6195
Subtract 4455 from 4710 to get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Advancing to step 13:
The number 891 fits into 2550 2 times, leaving a remainder of 768.
Use 2 as the next digit of our solution. 
Result so far: 62499.61952
The remainder is 768 after subtracting 1782 from 2550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

On to step 14:
If we divide 7680 by 891, we get 8 and a remainder of 552.
Record the quotient 8 as the next digit in the result. 
Result so far: 62499.619528
Subtracting 7128 from 7680 leaves us with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Moving on to step 15:
891 goes into 5520 6 times with a remainder of 174.
The next digit of our result is 6. 
Result so far: 62499.6195286
If we subtract 5346 from 5520, we get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Moving on to step 16:
891 can be fit into 1740 1 times, resulting in a remainder of 849.
The next digit of our result is 1. 
Result so far: 62499.61952861
The remainder is 849 after subtracting 891 from 1740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8490, and continue the process.
