53170216 ÷ 704 
We want to figure out the number of times 53170216 can be divided by 704.

Let's proceed to step 1:
704 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 704

On to step 2:
53 divided by 704 is 0 with a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Include the next digit (1) from the dividend after 53, then repeat: 531 / 704

On to step 3:
531 divided by 704 is 0 with a remainder of 531.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 531 leaves us with 531.
Append the next digit (7) from the dividend to 531 and continue with: 5317 / 704

Going ahead to step 4:
The number 704 fits into 5317 7 times, leaving a remainder of 389.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 4928 from 5317, we get 389.
Take the next digit (0) from the dividend and append it to 389, then repeat: 3890 / 704

Moving on to step 5:
704 can be fit into 3890 5 times, resulting in a remainder of 370.
Write down 5 as next digit of the result. 
Result so far: 75.0
Subtracting 3520 from 3890 leaves us with 370.
Take the next digit (2) from the dividend and append it to 370, then repeat: 3702 / 704

Advancing to step 6:
The number 704 fits into 3702 5 times, leaving a remainder of 182.
Put 5 as the next digit of the answer. 
Result so far: 755.0
Subtract 3520 from 3702 to get 182.
Bring next digit (1) of the dividend behind the 182 and repeat the process: 1821 / 704

Advancing to step 7:
If we divide 1821 by 704, we get 2 and a remainder of 413.
Use 2 as the next digit of our solution. 
Result so far: 7552.0
Subtracting 1408 from 1821 leaves us with 413.
Append the next digit (6) from the dividend to 413 and continue with: 4136 / 704

Going ahead to step 8:
When dividing 4136 by 704, we get 5 with a remainder of 616.
The next digit of our result is 5. 
Result so far: 75525.0
If we take 3520 away from 4136, we end up with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Let's proceed to step 9:
704 goes into 6160 8 times with a remainder of 528.
Put 8 as the next digit of the answer. 
Result so far: 75525.8
The remainder is 528 after subtracting 5632 from 6160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Step 10:
When dividing 5280 by 704, we get 7 with a remainder of 352.
Write down 7 as next digit of the result. 
Result so far: 75525.87
If we subtract 4928 from 5280, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Moving on to step 11:
704 goes into 3520 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 75525.875
Subtracting 3520 from 3520 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
When dividing 0 by 704, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 75525.875
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 13:
When dividing 0 by 704, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 75525.875
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 75525.875 with a remainder of 0.0.
