Let's divide 66342421 by 53
We're looking to find how many times 53 goes into 66342421.

On to step 1:
6 divided by 53 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 53

Let's proceed to step 2:
The number 53 fits into 66 1 times, leaving a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 53 from 66 to get 13.
Bring next digit (3) of the dividend behind the 13 and repeat the process: 133 / 53

Step 3:
53 goes into 133 2 times with a remainder of 27.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 106 away from 133, we end up with 27.
Take the next digit (4) from the dividend and append it to 27, then repeat: 274 / 53

On to step 4:
The number 53 fits into 274 5 times, leaving a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
Subtract 265 from 274 to get 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 53

Let's proceed to step 5:
53 can be fit into 92 1 times, resulting in a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 1251.0
If we subtract 53 from 92, we get 39.
Bring next digit (4) of the dividend behind the 39 and repeat the process: 394 / 53

On to step 6:
394 divided by 53 is 7 with a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 12517.0
Subtracting 371 from 394 leaves us with 23.
Append the next digit (2) from the dividend to 23 and continue with: 232 / 53

Advancing to step 7:
53 goes into 232 4 times with a remainder of 20.
The next digit of our result is 4. 
Result so far: 125174.0
Deduct 212 from 232 and we're left with 20.
Fetch the next digit (1) from the dividend, attach it to 20 and continue: 201 / 53

Step 8:
201 divided by 53 is 3 with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 1251743.0
Deduct 159 from 201 and we're left with 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 9:
53 goes into 420 7 times with a remainder of 49.
The next digit of our result is 7. 
Result so far: 1251743.7
Subtracting 371 from 420 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 10:
490 divided by 53 is 9 with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 1251743.79
Subtract 477 from 490 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 11:
If we divide 130 by 53, we get 2 and a remainder of 24.
The next digit of our result is 2. 
Result so far: 1251743.792
If we subtract 106 from 130, we 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.

Moving on to step 12:
240 divided by 53 is 4 with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 1251743.7924
Subtracting 212 from 240 leaves us 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.

Moving on to step 13:
If we divide 280 by 53, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 1251743.79245
Deduct 265 from 280 and we're left with 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 14:
53 can be fit into 150 2 times, resulting in a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 1251743.792452
If we subtract 106 from 150, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 15:
When dividing 440 by 53, we get 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 1251743.7924528
Subtracting 424 from 440 leaves us 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.

Going ahead to step 16:
When dividing 160 by 53, we get 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 1251743.79245283
If we take 159 away from 160, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final outcome is 1251743.79245283, with a leftover of 1e-09.
