668793 ÷ 53 
We want to figure out the number of times 668793 can be divided by 53.

Step 1:
The number 53 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 53

Moving on to step 2:
When dividing 66 by 53, we get 1 with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 53 from 66 leaves us with 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 53

Let's proceed to step 3:
The number 53 fits into 138 2 times, leaving a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Deduct 106 from 138 and we're left with 32.
Fetch the next digit (7) from the dividend, attach it to 32 and continue: 327 / 53

Moving on to step 4:
53 can be fit into 327 6 times, resulting in a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 126.0
Subtract 318 from 327 to get 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 53

Let's proceed to step 5:
53 goes into 99 1 times with a remainder of 46.
The next digit of our result is 1. 
Result so far: 1261.0
Deduct 53 from 99 and we're left with 46.
Take the next digit (3) from the dividend and append it to 46, then repeat: 463 / 53

Let's proceed to step 6:
If we divide 463 by 53, we get 8 and a remainder of 39.
The next digit of our result is 8. 
Result so far: 12618.0
Subtract 424 from 463 to 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.

On to step 7:
If we divide 390 by 53, we get 7 and a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 12618.7
Subtracting 371 from 390 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 8:
The number 53 fits into 190 3 times, leaving a remainder of 31.
Put 3 as the next digit of the answer. 
Result so far: 12618.73
If we subtract 159 from 190, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 9:
When dividing 310 by 53, we get 5 with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 12618.735
The remainder is 45 after subtracting 265 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 10:
If we divide 450 by 53, we get 8 and a remainder of 26.
The next digit of our result is 8. 
Result so far: 12618.7358
Subtract 424 from 450 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 11:
53 can be fit into 260 4 times, resulting in a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 12618.73584
Subtracting 212 from 260 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 12:
480 divided by 53 is 9 with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 12618.735849
If we take 477 away from 480, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 13:
If we divide 30 by 53, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 12618.735849
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 14:
The number 53 fits into 300 5 times, leaving a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 12618.73584905
If we subtract 265 from 300, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

After the division, we end up with 12618.73584905 and a remainder of 3.5e-08.
