3422407 divided by 815 
Our goal is to divide 3422407 by 815.

Step 1:
3 divided by 815 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 815

Advancing to step 2:
815 goes into 34 0 times with a remainder of 34.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 34 leaves us with 34.
Bring next digit (2) of the dividend behind the 34 and repeat the process: 342 / 815

Let's proceed to step 3:
When dividing 342 by 815, we get 0 with a remainder of 342.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 342, we end up with 342.
Bring next digit (2) of the dividend behind the 342 and repeat the process: 3422 / 815

Moving on to step 4:
815 can be fit into 3422 4 times, resulting in a remainder of 162.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 3260 from 3422, we get 162.
Grab the next digit (4) from the dividend, add it to 162, then carry on: 1624 / 815

On to step 5:
The number 815 fits into 1624 1 times, leaving a remainder of 809.
Use 1 as the next digit of our solution. 
Result so far: 41.0
If we take 815 away from 1624, we end up with 809.
Append the next digit (0) from the dividend to 809 and continue with: 8090 / 815

Going ahead to step 6:
When dividing 8090 by 815, we get 9 with a remainder of 755.
Record the quotient 9 as the next digit in the result. 
Result so far: 419.0
Subtract 7335 from 8090 to get 755.
Bring next digit (7) of the dividend behind the 755 and repeat the process: 7557 / 815

Advancing to step 7:
The number 815 fits into 7557 9 times, leaving a remainder of 222.
Write down 9 as next digit of the result. 
Result so far: 4199.0
Subtracting 7335 from 7557 leaves us with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Let's proceed to step 8:
If we divide 2220 by 815, we get 2 and a remainder of 590.
Write down 2 as next digit of the result. 
Result so far: 4199.2
If we subtract 1630 from 2220, we get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Going ahead to step 9:
When dividing 5900 by 815, we get 7 with a remainder of 195.
The number 7 becomes the next digit in our result. 
Result so far: 4199.27
Deduct 5705 from 5900 and we're left with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Let's proceed to step 10:
815 goes into 1950 2 times with a remainder of 320.
The number 2 becomes the next digit in our result. 
Result so far: 4199.272
If we subtract 1630 from 1950, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 11:
If we divide 3200 by 815, we get 3 and a remainder of 755.
Write down 3 as next digit of the result. 
Result so far: 4199.2723
If we subtract 2445 from 3200, we get 755.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7550, and continue the process.

Advancing to step 12:
When dividing 7550 by 815, we get 9 with a remainder of 215.
The next digit of our result is 9. 
Result so far: 4199.27239
If we take 7335 away from 7550, we end up with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Let's proceed to step 13:
2150 divided by 815 is 2 with a remainder of 520.
The number 2 becomes the next digit in our result. 
Result so far: 4199.272392
Subtract 1630 from 2150 to get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 14:
The number 815 fits into 5200 6 times, leaving a remainder of 310.
Write down 6 as next digit of the result. 
Result so far: 4199.2723926
If we subtract 4890 from 5200, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 15:
3100 divided by 815 is 3 with a remainder of 655.
Record the quotient 3 as the next digit in the result. 
Result so far: 4199.27239263
The remainder is 655 after subtracting 2445 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

After the division, we end up with 4199.27239263 and a remainder of 6.55e-07.
