We divide 1685805 by 410
We want to figure out the number of times 1685805 can be divided by 410.

Going ahead to step 1:
If we divide 1 by 410, we get 0 and 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 / 410

Going ahead to step 2:
410 goes into 16 0 times with a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Include the next digit (8) from the dividend after 16, then repeat: 168 / 410

Advancing to step 3:
If we divide 168 by 410, we get 0 and a remainder of 168.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 168 leaves us with 168.
Include the next digit (5) from the dividend after 168, then repeat: 1685 / 410

Advancing to step 4:
When dividing 1685 by 410, we get 4 with a remainder of 45.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 1640 from 1685, we get 45.
Take the next digit (8) from the dividend and append it to 45, then repeat: 458 / 410

Moving on to step 5:
When dividing 458 by 410, we get 1 with a remainder of 48.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
Subtracting 410 from 458 leaves us with 48.
Bring next digit (0) of the dividend behind the 48 and repeat the process: 480 / 410

Going ahead to step 6:
When dividing 480 by 410, we get 1 with a remainder of 70.
Use 1 as the next digit of our solution. 
Result so far: 411.0
The remainder is 70 after subtracting 410 from 480.
Append the next digit (5) from the dividend to 70 and continue with: 705 / 410

Advancing to step 7:
The number 410 fits into 705 1 times, leaving a remainder of 295.
The number 1 becomes the next digit in our result. 
Result so far: 4111.0
If we subtract 410 from 705, we get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Let's proceed to step 8:
When dividing 2950 by 410, we get 7 with a remainder of 80.
Write down 7 as next digit of the result. 
Result so far: 4111.7
Deduct 2870 from 2950 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 9:
When dividing 800 by 410, we get 1 with a remainder of 390.
The next digit of our result is 1. 
Result so far: 4111.71
Subtract 410 from 800 to get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Moving on to step 10:
The number 410 fits into 3900 9 times, leaving a remainder of 210.
The number 9 becomes the next digit in our result. 
Result so far: 4111.719
Deduct 3690 from 3900 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 11:
If we divide 2100 by 410, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 4111.7195
If we subtract 2050 from 2100, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 12:
410 can be fit into 500 1 times, resulting in a remainder of 90.
The next digit of our result is 1. 
Result so far: 4111.71951
Subtracting 410 from 500 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 13:
The number 410 fits into 900 2 times, leaving a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 4111.719512
Deduct 820 from 900 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 14:
410 can be fit into 800 1 times, resulting in a remainder of 390.
Put 1 as the next digit of the answer. 
Result so far: 4111.7195121
The remainder is 390 after subtracting 410 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 15:
3900 divided by 410 is 9 with a remainder of 210.
Record the quotient 9 as the next digit in the result. 
Result so far: 4111.71951219
If we take 3690 away from 3900, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Our division results in 4111.71951219 with a remaining 2.1e-07.
