623900 ÷ 52 
We want to figure out the number of times 623900 can be divided by 52.

On to step 1:
52 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 52

Moving on to step 2:
The number 52 fits into 62 1 times, leaving a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 52 from 62 and we're left with 10.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 52

Step 3:
The number 52 fits into 103 1 times, leaving a remainder of 51.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 52 away from 103, we end up with 51.
Take the next digit (9) from the dividend and append it to 51, then repeat: 519 / 52

On to step 4:
52 goes into 519 9 times with a remainder of 51.
Record the quotient 9 as the next digit in the result. 
Result so far: 119.0
Subtract 468 from 519 to get 51.
Include the next digit (0) from the dividend after 51, then repeat: 510 / 52

Step 5:
If we divide 510 by 52, we get 9 and a remainder of 42.
The next digit of our result is 9. 
Result so far: 1199.0
If we take 468 away from 510, we end up with 42.
Take the next digit (0) from the dividend and append it to 42, then repeat: 420 / 52

Advancing to step 6:
If we divide 420 by 52, we get 8 and a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 11998.0
Subtracting 416 from 420 leaves us 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.

Step 7:
52 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 11998.0
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
If we divide 400 by 52, we get 7 and a remainder of 36.
The next digit of our result is 7. 
Result so far: 11998.07
Deduct 364 from 400 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 9:
When dividing 360 by 52, we get 6 with a remainder of 48.
The next digit of our result is 6. 
Result so far: 11998.076
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 10:
52 can be fit into 480 9 times, resulting in a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 11998.0769
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.

Advancing to step 11:
When dividing 120 by 52, we get 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 11998.07692
The remainder is 16 after subtracting 104 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 12:
The number 52 fits into 160 3 times, leaving a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 11998.076923
Subtract 156 from 160 to get 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 13:
40 divided by 52 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 11998.076923
If we take 0 away from 40, we end up with 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 14:
If we divide 400 by 52, we get 7 and a remainder of 36.
Write down 7 as next digit of the result. 
Result so far: 11998.07692307
Deduct 364 from 400 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Our division results in 11998.07692307 with a remaining 3.6e-08.
