We divide 177896 by 21
We're looking to find how many times 21 goes into 177896.

Step 1:
If we divide 1 by 21, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 21

Step 2:
21 goes into 17 0 times with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 21

Let's proceed to step 3:
The number 21 fits into 177 8 times, leaving a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 168 from 177 and we're left with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 21

Moving on to step 4:
The number 21 fits into 98 4 times, leaving a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
Subtracting 84 from 98 leaves us with 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 21

Advancing to step 5:
If we divide 149 by 21, we get 7 and a remainder of 2.
The next digit of our result is 7. 
Result so far: 847.0
If we subtract 147 from 149, we get 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 21

Advancing to step 6:
When dividing 26 by 21, we get 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 8471.0
If we subtract 21 from 26, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
When dividing 50 by 21, we get 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 8471.2
Subtract 42 from 50 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
21 goes into 80 3 times with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 8471.23
Subtract 63 from 80 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 9:
170 divided by 21 is 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 8471.238
Subtract 168 from 170 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 10:
The number 21 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 8471.238
The remainder is 20 after subtracting 0 from 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 11:
When dividing 200 by 21, we get 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 8471.23809
Deduct 189 from 200 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 12:
21 goes into 110 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 8471.238095
Deduct 105 from 110 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 13:
If we divide 50 by 21, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 8471.2380952
Subtract 42 from 50 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 14:
21 can be fit into 80 3 times, resulting in a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 8471.23809523
Deduct 63 from 80 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Our division results in 8471.23809523 with a remaining 1.7e-08.
