18416921 divided by 412 
We're looking to find how many times 412 goes into 18416921.

Advancing to step 1:
If we divide 1 by 412, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 412

Step 2:
If we divide 18 by 412, we get 0 and a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Fetch the next digit (4) from the dividend, attach it to 18 and continue: 184 / 412

Moving on to step 3:
412 goes into 184 0 times with a remainder of 184.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 184 and we're left with 184.
Bring next digit (1) of the dividend behind the 184 and repeat the process: 1841 / 412

Step 4:
1841 divided by 412 is 4 with a remainder of 193.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 1648 from 1841 to get 193.
Grab the next digit (6) from the dividend, add it to 193, then carry on: 1936 / 412

Let's proceed to step 5:
412 goes into 1936 4 times with a remainder of 288.
Put 4 as the next digit of the answer. 
Result so far: 44.0
Subtract 1648 from 1936 to get 288.
Fetch the next digit (9) from the dividend, attach it to 288 and continue: 2889 / 412

Let's proceed to step 6:
2889 divided by 412 is 7 with a remainder of 5.
The next digit of our result is 7. 
Result so far: 447.0
Subtract 2884 from 2889 to get 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 412

Step 7:
If we divide 52 by 412, we get 0 and a remainder of 52.
The next digit of our result is 0. 
Result so far: 4470.0
Deduct 0 from 52 and we're left with 52.
Include the next digit (1) from the dividend after 52, then repeat: 521 / 412

On to step 8:
If we divide 521 by 412, we get 1 and a remainder of 109.
Write down 1 as next digit of the result. 
Result so far: 44701.0
If we take 412 away from 521, we end up with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Step 9:
1090 divided by 412 is 2 with a remainder of 266.
The number 2 becomes the next digit in our result. 
Result so far: 44701.2
If we take 824 away from 1090, we end up with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Moving on to step 10:
The number 412 fits into 2660 6 times, leaving a remainder of 188.
The number 6 becomes the next digit in our result. 
Result so far: 44701.26
If we take 2472 away from 2660, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Advancing to step 11:
412 can be fit into 1880 4 times, resulting in a remainder of 232.
The next digit of our result is 4. 
Result so far: 44701.264
If we take 1648 away from 1880, we end up with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 12:
The number 412 fits into 2320 5 times, leaving a remainder of 260.
Write down 5 as next digit of the result. 
Result so far: 44701.2645
Subtract 2060 from 2320 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 13:
2600 divided by 412 is 6 with a remainder of 128.
Record the quotient 6 as the next digit in the result. 
Result so far: 44701.26456
The remainder is 128 after subtracting 2472 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 14:
412 goes into 1280 3 times with a remainder of 44.
Write down 3 as next digit of the result. 
Result so far: 44701.264563
Deduct 1236 from 1280 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 15:
If we divide 440 by 412, we get 1 and a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 44701.2645631
Subtract 412 from 440 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 16:
The number 412 fits into 280 0 times, leaving a remainder of 280.
Use 0 as the next digit of our solution. 
Result so far: 44701.2645631
If we subtract 0 from 280, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

The final outcome is 44701.2645631, with a leftover of 2.8e-07.
