1622109 ÷ 409 
We want to divide 1622109 by 409.

Moving on to step 1:
409 can be fit into 1 0 times, resulting in 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.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 409

Moving on to step 2:
409 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 subtract 0 from 16, we get 16.
Take the next digit (2) from the dividend and append it to 16, then repeat: 162 / 409

Advancing to step 3:
162 divided by 409 is 0 with a remainder of 162.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 162 to get 162.
Grab the next digit (2) from the dividend, add it to 162, then carry on: 1622 / 409

Advancing to step 4:
The number 409 fits into 1622 3 times, leaving a remainder of 395.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 1227 from 1622 to get 395.
Grab the next digit (1) from the dividend, add it to 395, then carry on: 3951 / 409

Moving on to step 5:
409 goes into 3951 9 times with a remainder of 270.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
Subtract 3681 from 3951 to get 270.
Grab the next digit (0) from the dividend, add it to 270, then carry on: 2700 / 409

Step 6:
If we divide 2700 by 409, we get 6 and a remainder of 246.
Use 6 as the next digit of our solution. 
Result so far: 396.0
Subtracting 2454 from 2700 leaves us with 246.
Bring next digit (9) of the dividend behind the 246 and repeat the process: 2469 / 409

On to step 7:
The number 409 fits into 2469 6 times, leaving a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 3966.0
The remainder is 15 after subtracting 2454 from 2469.
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 8:
150 divided by 409 is 0 with a remainder of 150.
The next digit of our result is 0. 
Result so far: 3966.0
Subtracting 0 from 150 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 9:
1500 divided by 409 is 3 with a remainder of 273.
Use 3 as the next digit of our solution. 
Result so far: 3966.03
Deduct 1227 from 1500 and we're left with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Step 10:
When dividing 2730 by 409, we get 6 with a remainder of 276.
Write down 6 as next digit of the result. 
Result so far: 3966.036
Subtracting 2454 from 2730 leaves us with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

On to step 11:
409 goes into 2760 6 times with a remainder of 306.
Record the quotient 6 as the next digit in the result. 
Result so far: 3966.0366
Subtract 2454 from 2760 to get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Our division results in 3966.0366 with a remaining 0.00306.
