16420074 ÷ 324 
We want to figure out the number of times 16420074 can be divided by 324.

Moving on to step 1:
If we divide 1 by 324, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 324

On to step 2:
When dividing 16 by 324, we get 0 with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Include the next digit (4) from the dividend after 16, then repeat: 164 / 324

On to step 3:
When dividing 164 by 324, we get 0 with a remainder of 164.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 164, we end up with 164.
Append the next digit (2) from the dividend to 164 and continue with: 1642 / 324

Step 4:
When dividing 1642 by 324, we get 5 with a remainder of 22.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 1620 from 1642, we get 22.
Take the next digit (0) from the dividend and append it to 22, then repeat: 220 / 324

On to step 5:
The number 324 fits into 220 0 times, leaving a remainder of 220.
Write down 0 as next digit of the result. 
Result so far: 50.0
Deduct 0 from 220 and we're left with 220.
Include the next digit (0) from the dividend after 220, then repeat: 2200 / 324

Advancing to step 6:
2200 divided by 324 is 6 with a remainder of 256.
Put 6 as the next digit of the answer. 
Result so far: 506.0
If we take 1944 away from 2200, we end up with 256.
Bring next digit (7) of the dividend behind the 256 and repeat the process: 2567 / 324

Moving on to step 7:
324 goes into 2567 7 times with a remainder of 299.
Write down 7 as next digit of the result. 
Result so far: 5067.0
If we take 2268 away from 2567, we end up with 299.
Grab the next digit (4) from the dividend, add it to 299, then carry on: 2994 / 324

Moving on to step 8:
The number 324 fits into 2994 9 times, leaving a remainder of 78.
The number 9 becomes the next digit in our result. 
Result so far: 50679.0
Subtracting 2916 from 2994 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 9:
If we divide 780 by 324, we get 2 and a remainder of 132.
Write down 2 as next digit of the result. 
Result so far: 50679.2
Subtract 648 from 780 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 10:
The number 324 fits into 1320 4 times, leaving a remainder of 24.
The next digit of our result is 4. 
Result so far: 50679.24
If we take 1296 away from 1320, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 11:
If we divide 240 by 324, we get 0 and a remainder of 240.
The next digit of our result is 0. 
Result so far: 50679.24
If we take 0 away from 240, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 12:
324 goes into 2400 7 times with a remainder of 132.
Record the quotient 7 as the next digit in the result. 
Result so far: 50679.2407
Subtracting 2268 from 2400 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Advancing to step 13:
324 can be fit into 1320 4 times, resulting in a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 50679.24074
Subtract 1296 from 1320 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 14:
The number 324 fits into 240 0 times, leaving a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 50679.24074
Deduct 0 from 240 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 15:
324 goes into 2400 7 times with a remainder of 132.
The next digit of our result is 7. 
Result so far: 50679.2407407
Subtracting 2268 from 2400 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 16:
When dividing 1320 by 324, we get 4 with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 50679.24074074
Subtract 1296 from 1320 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 50679.24074074 with a remainder of 2.4e-08.
