We're dividing 642455 by 53 
We want to figure out the number of times 642455 can be divided by 53.

Let's proceed to step 1:
When dividing 6 by 53, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 53

Step 2:
The number 53 fits into 64 1 times, leaving a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 53 from 64 and we're left with 11.
Take the next digit (2) from the dividend and append it to 11, then repeat: 112 / 53

Moving on to step 3:
When dividing 112 by 53, we get 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 106 from 112 leaves us with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 53

On to step 4:
53 goes into 64 1 times with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 121.0
If we take 53 away from 64, we end up with 11.
Bring next digit (5) of the dividend behind the 11 and repeat the process: 115 / 53

Going ahead to step 5:
115 divided by 53 is 2 with a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 1212.0
The remainder is 9 after subtracting 106 from 115.
Append the next digit (5) from the dividend to 9 and continue with: 95 / 53

Going ahead to step 6:
If we divide 95 by 53, we get 1 and a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 12121.0
If we subtract 53 from 95, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 7:
53 goes into 420 7 times with a remainder of 49.
The next digit of our result is 7. 
Result so far: 12121.7
The remainder is 49 after subtracting 371 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 8:
If we divide 490 by 53, we get 9 and a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 12121.79
If we take 477 away from 490, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 9:
When dividing 130 by 53, we get 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 12121.792
The remainder is 24 after subtracting 106 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 10:
When dividing 240 by 53, we get 4 with a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 12121.7924
Deduct 212 from 240 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 11:
The number 53 fits into 280 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 12121.79245
If we subtract 265 from 280, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 12:
When dividing 150 by 53, we get 2 with a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 12121.792452
Deduct 106 from 150 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 13:
53 can be fit into 440 8 times, resulting in a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 12121.7924528
If we take 424 away from 440, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 14:
If we divide 160 by 53, we get 3 and a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 12121.79245283
If we subtract 159 from 160, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 12121.79245283 and a remainder of 1e-09.
