16418891 divided by 410 
We want to figure out the number of times 16418891 can be divided by 410.

Step 1:
The number 410 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 410

Let's proceed to step 2:
16 divided by 410 is 0 with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 410

Advancing to step 3:
When dividing 164 by 410, we get 0 with a remainder of 164.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 164, we end up with 164.
Fetch the next digit (1) from the dividend, attach it to 164 and continue: 1641 / 410

Let's proceed to step 4:
1641 divided by 410 is 4 with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 1640 away from 1641, we end up with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 410

On to step 5:
410 can be fit into 18 0 times, resulting in a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
Deduct 0 from 18 and we're left with 18.
Include the next digit (8) from the dividend after 18, then repeat: 188 / 410

On to step 6:
410 can be fit into 188 0 times, resulting in a remainder of 188.
The next digit of our result is 0. 
Result so far: 400.0
Subtract 0 from 188 to get 188.
Include the next digit (9) from the dividend after 188, then repeat: 1889 / 410

Advancing to step 7:
410 goes into 1889 4 times with a remainder of 249.
Record the quotient 4 as the next digit in the result. 
Result so far: 4004.0
If we take 1640 away from 1889, we end up with 249.
Fetch the next digit (1) from the dividend, attach it to 249 and continue: 2491 / 410

Going ahead to step 8:
410 can be fit into 2491 6 times, resulting in a remainder of 31.
Write down 6 as next digit of the result. 
Result so far: 40046.0
The remainder is 31 after subtracting 2460 from 2491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 9:
410 can be fit into 310 0 times, resulting in a remainder of 310.
The next digit of our result is 0. 
Result so far: 40046.0
If we take 0 away from 310, we end up with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

On to step 10:
If we divide 3100 by 410, we get 7 and a remainder of 230.
The number 7 becomes the next digit in our result. 
Result so far: 40046.07
If we subtract 2870 from 3100, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 11:
2300 divided by 410 is 5 with a remainder of 250.
Write down 5 as next digit of the result. 
Result so far: 40046.075
If we subtract 2050 from 2300, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 12:
If we divide 2500 by 410, we get 6 and a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 40046.0756
Subtracting 2460 from 2500 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 13:
410 can be fit into 400 0 times, resulting in a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 40046.0756
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 14:
410 can be fit into 4000 9 times, resulting in a remainder of 310.
Record the quotient 9 as the next digit in the result. 
Result so far: 40046.075609
If we subtract 3690 from 4000, 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.

Let's proceed to step 15:
When dividing 3100 by 410, we get 7 with a remainder of 230.
Put 7 as the next digit of the answer. 
Result so far: 40046.0756097
The remainder is 230 after subtracting 2870 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 16:
If we divide 2300 by 410, we get 5 and a remainder of 250.
The next digit of our result is 5. 
Result so far: 40046.07560975
If we subtract 2050 from 2300, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

After the division, we end up with 40046.07560975 and a remainder of 2.5e-07.
