We look at the division of 177648 by 21 
We want to figure out the number of times 177648 can be divided by 21.

Moving on to step 1:
1 divided by 21 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 21

Let's proceed to step 2:
21 can be fit into 17 0 times, resulting in a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Bring next digit (7) of the dividend behind the 17 and repeat the process: 177 / 21

Moving on to step 3:
The number 21 fits into 177 8 times, leaving a remainder of 9.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 168 from 177 leaves us with 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 21

Advancing to step 4:
The number 21 fits into 96 4 times, leaving a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 84.0
Deduct 84 from 96 and we're left with 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 21

On to step 5:
The number 21 fits into 124 5 times, leaving a remainder of 19.
Use 5 as the next digit of our solution. 
Result so far: 845.0
If we take 105 away from 124, we end up with 19.
Append the next digit (8) from the dividend to 19 and continue with: 198 / 21

Advancing to step 6:
If we divide 198 by 21, we get 9 and a remainder of 9.
The next digit of our result is 9. 
Result so far: 8459.0
Deduct 189 from 198 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
90 divided by 21 is 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 8459.4
Subtract 84 from 90 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
60 divided by 21 is 2 with a remainder of 18.
The next digit of our result is 2. 
Result so far: 8459.42
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 9:
When dividing 180 by 21, we get 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 8459.428
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
21 goes into 120 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 8459.4285
Subtracting 105 from 120 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 11:
150 divided by 21 is 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 8459.42857
Deduct 147 from 150 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 12:
When dividing 30 by 21, we get 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 8459.428571
If we subtract 21 from 30, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 13:
When dividing 90 by 21, we get 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 8459.4285714
Subtract 84 from 90 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 14:
60 divided by 21 is 2 with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 8459.42857142
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The quotient of the division is 8459.42857142, and the remainder is 1.8e-08.
