Let's divide 164465 by 21
We want to figure out the number of times 164465 can be divided by 21.

Moving on to step 1:
1 divided by 21 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 21

Step 2:
21 can be fit into 16 0 times, resulting in a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Include the next digit (4) from the dividend after 16, then repeat: 164 / 21

Let's proceed to step 3:
The number 21 fits into 164 7 times, leaving a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 17 after subtracting 147 from 164.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 21

On to step 4:
When dividing 174 by 21, we get 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 78.0
Subtract 168 from 174 to get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 21

Step 5:
If we divide 66 by 21, we get 3 and a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 783.0
If we subtract 63 from 66, we get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 21

On to step 6:
When dividing 35 by 21, we get 1 with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 7831.0
Subtract 21 from 35 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
The number 21 fits into 140 6 times, leaving a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 7831.6
If we take 126 away from 140, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
21 goes into 140 6 times with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 7831.66
If we take 126 away from 140, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 7831.66, with a leftover of 0.014.
