We divide 325778 by 21
We're looking to find how many times 21 goes into 325778.

Going ahead to step 1:
When dividing 3 by 21, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 21

Step 2:
21 goes into 32 1 times with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 21 from 32 to get 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 21

Going ahead to step 3:
The number 21 fits into 115 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we subtract 105 from 115, we get 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 21

Going ahead to step 4:
When dividing 107 by 21, we get 5 with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 155.0
Subtracting 105 from 107 leaves us with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 21

Let's proceed to step 5:
If we divide 27 by 21, we get 1 and a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1551.0
Subtracting 21 from 27 leaves us with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 21

Moving on to step 6:
If we divide 68 by 21, we get 3 and a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 15513.0
If we take 63 away from 68, we end up 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.

Moving on to step 7:
If we divide 50 by 21, we get 2 and a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 15513.2
If we take 42 away from 50, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
When dividing 80 by 21, we get 3 with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 15513.23
Subtracting 63 from 80 leaves us 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.

Advancing to step 9:
170 divided by 21 is 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 15513.238
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.

Step 10:
20 divided by 21 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 15513.238
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.

Step 11:
21 can be fit into 200 9 times, resulting in a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 15513.23809
Subtracting 189 from 200 leaves us 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.

On to step 12:
21 goes into 110 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 15513.238095
Subtracting 105 from 110 leaves us 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.

Advancing to step 13:
50 divided by 21 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 15513.2380952
If we subtract 42 from 50, we 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.

Let's proceed to step 14:
When dividing 80 by 21, we get 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 15513.23809523
Subtracting 63 from 80 leaves us 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.

After the division, we end up with 15513.23809523 and a remainder of 1.7e-08.
