We're dividing 645888 by 52 
We're looking to find how many times 52 goes into 645888.

Advancing to step 1:
If we divide 6 by 52, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 52

Going ahead to step 2:
The number 52 fits into 64 1 times, leaving a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 52 from 64 leaves us with 12.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 52

Let's proceed to step 3:
52 can be fit into 125 2 times, resulting in a remainder of 21.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 104 from 125 leaves us with 21.
Fetch the next digit (8) from the dividend, attach it to 21 and continue: 218 / 52

Going ahead to step 4:
When dividing 218 by 52, we get 4 with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 124.0
Subtracting 208 from 218 leaves us with 10.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 52

Step 5:
52 goes into 108 2 times with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 1242.0
If we take 104 away from 108, we end up with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 52

On to step 6:
When dividing 48 by 52, we get 0 with a remainder of 48.
Write down 0 as next digit of the result. 
Result so far: 12420.0
Deduct 0 from 48 and we're left 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.

Going ahead to step 7:
52 goes into 480 9 times with a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 12420.9
The remainder is 12 after subtracting 468 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
52 goes into 120 2 times with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 12420.92
If we subtract 104 from 120, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
The number 52 fits into 160 3 times, leaving a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 12420.923
If we take 156 away from 160, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
52 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 12420.923
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
The number 52 fits into 400 7 times, leaving a remainder of 36.
The number 7 becomes the next digit in our result. 
Result so far: 12420.92307
If we subtract 364 from 400, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 12:
The number 52 fits into 360 6 times, leaving a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 12420.923076
If we subtract 312 from 360, we get 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 13:
If we divide 480 by 52, we get 9 and a remainder of 12.
The next digit of our result is 9. 
Result so far: 12420.9230769
Subtracting 468 from 480 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 14:
If we divide 120 by 52, we get 2 and a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 12420.92307692
Subtract 104 from 120 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 12420.92307692 and a remainder of 1.6e-08.
