We look at the division of 770486 by 53 
We're looking to find how many times 53 goes into 770486.

Moving on to step 1:
53 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 53

Moving on to step 2:
If we divide 77 by 53, we get 1 and a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 53 from 77, we get 24.
Append the next digit (0) from the dividend to 24 and continue with: 240 / 53

Let's proceed to step 3:
53 can be fit into 240 4 times, resulting in a remainder of 28.
The next digit of our result is 4. 
Result so far: 14.0
Subtracting 212 from 240 leaves us with 28.
Append the next digit (4) from the dividend to 28 and continue with: 284 / 53

Advancing to step 4:
284 divided by 53 is 5 with a remainder of 19.
Write down 5 as next digit of the result. 
Result so far: 145.0
If we take 265 away from 284, we end up with 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 53

Going ahead to step 5:
The number 53 fits into 198 3 times, leaving a remainder of 39.
Write down 3 as next digit of the result. 
Result so far: 1453.0
The remainder is 39 after subtracting 159 from 198.
Take the next digit (6) from the dividend and append it to 39, then repeat: 396 / 53

Moving on to step 6:
396 divided by 53 is 7 with a remainder of 25.
The number 7 becomes the next digit in our result. 
Result so far: 14537.0
If we take 371 away from 396, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 7:
53 can be fit into 250 4 times, resulting in a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 14537.4
Subtracting 212 from 250 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 8:
The number 53 fits into 380 7 times, leaving a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 14537.47
If we take 371 away from 380, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 9:
53 can be fit into 90 1 times, resulting in a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 14537.471
Deduct 53 from 90 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 10:
53 goes into 370 6 times with a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 14537.4716
Subtracting 318 from 370 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 11:
When dividing 520 by 53, we get 9 with a remainder of 43.
Record the quotient 9 as the next digit in the result. 
Result so far: 14537.47169
Subtracting 477 from 520 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 12:
53 can be fit into 430 8 times, resulting in a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 14537.471698
Deduct 424 from 430 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 13:
60 divided by 53 is 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 14537.4716981
Deduct 53 from 60 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 14:
53 goes into 70 1 times with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 14537.47169811
If we subtract 53 from 70, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

After the division, we end up with 14537.47169811 and a remainder of 1.7e-08.
