177474 divided by 21 
Let's see how many times 21 fits into 177474.

On to step 1:
The number 21 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 21

Let's proceed to step 2:
17 divided by 21 is 0 with a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Bring next digit (7) of the dividend behind the 17 and repeat the process: 177 / 21

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
Deduct 168 from 177 and we're left with 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 21

Moving on to step 4:
The number 21 fits into 94 4 times, leaving a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 84.0
If we subtract 84 from 94, we get 10.
Bring next digit (7) of the dividend behind the 10 and repeat the process: 107 / 21

Moving on to step 5:
If we divide 107 by 21, we get 5 and a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 845.0
Deduct 105 from 107 and we're left with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 21

Let's proceed to step 6:
If we divide 24 by 21, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 8451.0
Deduct 21 from 24 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.

Let's proceed to step 7:
30 divided by 21 is 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 8451.1
If we take 21 away from 30, we end up 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.

Advancing to step 8:
When dividing 90 by 21, we get 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 8451.14
The remainder is 6 after subtracting 84 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
21 can be fit into 60 2 times, resulting in a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 8451.142
If we take 42 away from 60, we end up 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.

Let's proceed to step 10:
21 can be fit into 180 8 times, resulting in a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 8451.1428
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 11:
21 goes into 120 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 8451.14285
Subtract 105 from 120 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 12:
If we divide 150 by 21, we get 7 and a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 8451.142857
If we subtract 147 from 150, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 13:
If we divide 30 by 21, we get 1 and a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 8451.1428571
Subtract 21 from 30 to 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.

Step 14:
90 divided by 21 is 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 8451.14285714
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.

After the division, we end up with 8451.14285714 and a remainder of 6e-09.
