669448 ÷ 53 
We want to figure out the number of times 669448 can be divided by 53.

Going ahead to step 1:
53 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 53

Let's proceed to step 2:
When dividing 66 by 53, we get 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 53 away from 66, we end up with 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 53

Going ahead to step 3:
53 can be fit into 139 2 times, resulting in a remainder of 33.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 106 from 139 and we're left with 33.
Take the next digit (4) from the dividend and append it to 33, then repeat: 334 / 53

Let's proceed to step 4:
53 goes into 334 6 times with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 126.0
If we take 318 away from 334, we end up with 16.
Append the next digit (4) from the dividend to 16 and continue with: 164 / 53

Moving on to step 5:
When dividing 164 by 53, we get 3 with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 1263.0
If we take 159 away from 164, we end up with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 53

Moving on to step 6:
If we divide 58 by 53, we get 1 and a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 12631.0
If we subtract 53 from 58, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
The number 53 fits into 50 0 times, leaving a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 12631.0
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
If we divide 500 by 53, we get 9 and a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 12631.09
Deduct 477 from 500 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 9:
The number 53 fits into 230 4 times, leaving a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 12631.094
Subtract 212 from 230 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 10:
The number 53 fits into 180 3 times, leaving a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 12631.0943
If we subtract 159 from 180, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 11:
210 divided by 53 is 3 with a remainder of 51.
The next digit of our result is 3. 
Result so far: 12631.09433
If we subtract 159 from 210, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The final outcome is 12631.09433, with a leftover of 5.1e-05.
