Let's divide 53365635 by 321
We're looking to find how many times 321 goes into 53365635.

On to step 1:
The number 321 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 321

Moving on to step 2:
When dividing 53 by 321, we get 0 with a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Append the next digit (3) from the dividend to 53 and continue with: 533 / 321

Advancing to step 3:
The number 321 fits into 533 1 times, leaving a remainder of 212.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 321 from 533 and we're left with 212.
Append the next digit (6) from the dividend to 212 and continue with: 2126 / 321

Advancing to step 4:
If we divide 2126 by 321, we get 6 and a remainder of 200.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtracting 1926 from 2126 leaves us with 200.
Grab the next digit (5) from the dividend, add it to 200, then carry on: 2005 / 321

Step 5:
When dividing 2005 by 321, we get 6 with a remainder of 79.
Record the quotient 6 as the next digit in the result. 
Result so far: 166.0
If we take 1926 away from 2005, we end up with 79.
Append the next digit (6) from the dividend to 79 and continue with: 796 / 321

Let's proceed to step 6:
The number 321 fits into 796 2 times, leaving a remainder of 154.
Use 2 as the next digit of our solution. 
Result so far: 1662.0
Subtracting 642 from 796 leaves us with 154.
Append the next digit (3) from the dividend to 154 and continue with: 1543 / 321

Step 7:
1543 divided by 321 is 4 with a remainder of 259.
Record the quotient 4 as the next digit in the result. 
Result so far: 16624.0
If we subtract 1284 from 1543, we get 259.
Include the next digit (5) from the dividend after 259, then repeat: 2595 / 321

Let's proceed to step 8:
321 can be fit into 2595 8 times, resulting in a remainder of 27.
Record the quotient 8 as the next digit in the result. 
Result so far: 166248.0
If we take 2568 away from 2595, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 9:
270 divided by 321 is 0 with a remainder of 270.
The next digit of our result is 0. 
Result so far: 166248.0
If we take 0 away from 270, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Going ahead to step 10:
321 can be fit into 2700 8 times, resulting in a remainder of 132.
The next digit of our result is 8. 
Result so far: 166248.08
Subtract 2568 from 2700 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.

On to step 11:
321 can be fit into 1320 4 times, resulting in a remainder of 36.
The next digit of our result is 4. 
Result so far: 166248.084
Deduct 1284 from 1320 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 12:
360 divided by 321 is 1 with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 166248.0841
If we subtract 321 from 360, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 13:
321 can be fit into 390 1 times, resulting in a remainder of 69.
The next digit of our result is 1. 
Result so far: 166248.08411
The remainder is 69 after subtracting 321 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

The final outcome is 166248.08411, with a leftover of 6.9e-05.
