We're dividing 52907521 by 324 
We want to figure out the number of times 52907521 can be divided by 324.

Let's proceed to step 1:
When dividing 5 by 324, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 324

Going ahead to step 2:
The number 324 fits into 52 0 times, leaving a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 52 after subtracting 0 from 52.
Bring next digit (9) of the dividend behind the 52 and repeat the process: 529 / 324

Let's proceed to step 3:
The number 324 fits into 529 1 times, leaving a remainder of 205.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 324 from 529 to get 205.
Append the next digit (0) from the dividend to 205 and continue with: 2050 / 324

On to step 4:
324 goes into 2050 6 times with a remainder of 106.
Use 6 as the next digit of our solution. 
Result so far: 16.0
The remainder is 106 after subtracting 1944 from 2050.
Append the next digit (7) from the dividend to 106 and continue with: 1067 / 324

On to step 5:
When dividing 1067 by 324, we get 3 with a remainder of 95.
Use 3 as the next digit of our solution. 
Result so far: 163.0
Subtracting 972 from 1067 leaves us with 95.
Append the next digit (5) from the dividend to 95 and continue with: 955 / 324

Moving on to step 6:
If we divide 955 by 324, we get 2 and a remainder of 307.
Write down 2 as next digit of the result. 
Result so far: 1632.0
Deduct 648 from 955 and we're left with 307.
Fetch the next digit (2) from the dividend, attach it to 307 and continue: 3072 / 324

On to step 7:
324 goes into 3072 9 times with a remainder of 156.
Put 9 as the next digit of the answer. 
Result so far: 16329.0
Deduct 2916 from 3072 and we're left with 156.
Bring next digit (1) of the dividend behind the 156 and repeat the process: 1561 / 324

On to step 8:
1561 divided by 324 is 4 with a remainder of 265.
Use 4 as the next digit of our solution. 
Result so far: 163294.0
Deduct 1296 from 1561 and we're left with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

On to step 9:
If we divide 2650 by 324, we get 8 and a remainder of 58.
The next digit of our result is 8. 
Result so far: 163294.8
Deduct 2592 from 2650 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 10:
If we divide 580 by 324, we get 1 and a remainder of 256.
The next digit of our result is 1. 
Result so far: 163294.81
If we take 324 away from 580, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 11:
If we divide 2560 by 324, we get 7 and a remainder of 292.
Put 7 as the next digit of the answer. 
Result so far: 163294.817
If we take 2268 away from 2560, we end up with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

On to step 12:
If we divide 2920 by 324, we get 9 and a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 163294.8179
Subtract 2916 from 2920 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
When dividing 40 by 324, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 163294.8179
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 14:
400 divided by 324 is 1 with a remainder of 76.
Use 1 as the next digit of our solution. 
Result so far: 163294.817901
Deduct 324 from 400 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 15:
324 goes into 760 2 times with a remainder of 112.
Write down 2 as next digit of the result. 
Result so far: 163294.8179012
If we subtract 648 from 760, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 16:
When dividing 1120 by 324, we get 3 with a remainder of 148.
Record the quotient 3 as the next digit in the result. 
Result so far: 163294.81790123
Deduct 972 from 1120 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

After the division, we end up with 163294.81790123 and a remainder of 1.48e-07.
