We look at the division of 45830303 by 53 
Let's see how many times 53 fits into 45830303.

Step 1:
53 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 53

Moving on to step 2:
45 divided by 53 is 0 with a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Grab the next digit (8) from the dividend, add it to 45, then carry on: 458 / 53

Going ahead to step 3:
53 can be fit into 458 8 times, resulting in a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 34 after subtracting 424 from 458.
Append the next digit (3) from the dividend to 34 and continue with: 343 / 53

On to step 4:
53 can be fit into 343 6 times, resulting in a remainder of 25.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
If we subtract 318 from 343, we get 25.
Fetch the next digit (0) from the dividend, attach it to 25 and continue: 250 / 53

Moving on to step 5:
53 goes into 250 4 times with a remainder of 38.
Write down 4 as next digit of the result. 
Result so far: 864.0
Subtracting 212 from 250 leaves us with 38.
Take the next digit (3) from the dividend and append it to 38, then repeat: 383 / 53

Step 6:
383 divided by 53 is 7 with a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 8647.0
Subtract 371 from 383 to get 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 53

Advancing to step 7:
120 divided by 53 is 2 with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 86472.0
The remainder is 14 after subtracting 106 from 120.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 53

Advancing to step 8:
When dividing 143 by 53, we get 2 with a remainder of 37.
The next digit of our result is 2. 
Result so far: 864722.0
Subtracting 106 from 143 leaves us 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.

Going ahead to step 9:
370 divided by 53 is 6 with a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 864722.6
If we take 318 away from 370, we end up 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.

Advancing to step 10:
53 goes into 520 9 times with a remainder of 43.
Write down 9 as next digit of the result. 
Result so far: 864722.69
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.

On to step 11:
53 can be fit into 430 8 times, resulting in a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 864722.698
If we take 424 away from 430, we end up 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.

Going ahead to step 12:
When dividing 60 by 53, we get 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 864722.6981
Subtracting 53 from 60 leaves us 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.

On to step 13:
The number 53 fits into 70 1 times, leaving a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 864722.69811
Subtract 53 from 70 to 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.

Our division results in 864722.69811 with a remaining 1.7e-05.
