We look at the division of 3557985 by 324 
Our goal is to divide 3557985 by 324.

Step 1:
If we divide 3 by 324, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 324

Step 2:
The number 324 fits into 35 0 times, leaving a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Include the next digit (5) from the dividend after 35, then repeat: 355 / 324

On to step 3:
If we divide 355 by 324, we get 1 and a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 324 from 355, we get 31.
Bring next digit (7) of the dividend behind the 31 and repeat the process: 317 / 324

Step 4:
When dividing 317 by 324, we get 0 with a remainder of 317.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 317 leaves us with 317.
Take the next digit (9) from the dividend and append it to 317, then repeat: 3179 / 324

On to step 5:
3179 divided by 324 is 9 with a remainder of 263.
Use 9 as the next digit of our solution. 
Result so far: 109.0
Subtract 2916 from 3179 to get 263.
Append the next digit (8) from the dividend to 263 and continue with: 2638 / 324

Let's proceed to step 6:
324 can be fit into 2638 8 times, resulting in a remainder of 46.
Use 8 as the next digit of our solution. 
Result so far: 1098.0
The remainder is 46 after subtracting 2592 from 2638.
Fetch the next digit (5) from the dividend, attach it to 46 and continue: 465 / 324

Moving on to step 7:
If we divide 465 by 324, we get 1 and a remainder of 141.
The number 1 becomes the next digit in our result. 
Result so far: 10981.0
The remainder is 141 after subtracting 324 from 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

On to step 8:
If we divide 1410 by 324, we get 4 and a remainder of 114.
The next digit of our result is 4. 
Result so far: 10981.4
If we subtract 1296 from 1410, we get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Moving on to step 9:
1140 divided by 324 is 3 with a remainder of 168.
Put 3 as the next digit of the answer. 
Result so far: 10981.43
If we take 972 away from 1140, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Advancing to step 10:
1680 divided by 324 is 5 with a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 10981.435
If we subtract 1620 from 1680, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 11:
The number 324 fits into 600 1 times, leaving a remainder of 276.
Record the quotient 1 as the next digit in the result. 
Result so far: 10981.4351
Subtracting 324 from 600 leaves us with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Step 12:
324 can be fit into 2760 8 times, resulting in a remainder of 168.
Record the quotient 8 as the next digit in the result. 
Result so far: 10981.43518
The remainder is 168 after subtracting 2592 from 2760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

On to step 13:
1680 divided by 324 is 5 with a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 10981.435185
If we take 1620 away from 1680, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 14:
If we divide 600 by 324, we get 1 and a remainder of 276.
Put 1 as the next digit of the answer. 
Result so far: 10981.4351851
Subtract 324 from 600 to get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Advancing to step 15:
The number 324 fits into 2760 8 times, leaving a remainder of 168.
Put 8 as the next digit of the answer. 
Result so far: 10981.43518518
If we take 2592 away from 2760, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

After the division, we end up with 10981.43518518 and a remainder of 1.68e-07.
