We look at the division of 405821 by 48 
We want to divide 405821 by 48.

Let's proceed to step 1:
When dividing 4 by 48, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 48

Step 2:
48 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Fetch the next digit (5) from the dividend, attach it to 40 and continue: 405 / 48

Step 3:
405 divided by 48 is 8 with a remainder of 21.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 384 away from 405, we end up with 21.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 48

Going ahead to step 4:
48 can be fit into 218 4 times, resulting in a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
If we take 192 away from 218, we end up with 26.
Append the next digit (2) from the dividend to 26 and continue with: 262 / 48

Let's proceed to step 5:
When dividing 262 by 48, we get 5 with a remainder of 22.
Use 5 as the next digit of our solution. 
Result so far: 845.0
Subtract 240 from 262 to get 22.
Grab the next digit (1) from the dividend, add it to 22, then carry on: 221 / 48

Advancing to step 6:
221 divided by 48 is 4 with a remainder of 29.
Record the quotient 4 as the next digit in the result. 
Result so far: 8454.0
If we take 192 away from 221, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 7:
The number 48 fits into 290 6 times, leaving a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 8454.6
Subtract 288 from 290 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.

Let's proceed to step 8:
20 divided by 48 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 8454.6
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
200 divided by 48 is 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 8454.604
Subtract 192 from 200 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.

Advancing to step 10:
The number 48 fits into 80 1 times, leaving a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 8454.6041
If we take 48 away from 80, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 11:
320 divided by 48 is 6 with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 8454.60416
Subtract 288 from 320 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 12:
320 divided by 48 is 6 with a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 8454.604166
Deduct 288 from 320 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 8454.604166, with a leftover of 3.2e-06.
