We look at the division of 643644 by 52 
Let's see how many times 52 fits into 643644.

Advancing to step 1:
52 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 52

Let's proceed 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
Subtract 52 from 64 to get 12.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 52

Advancing to step 3:
52 can be fit into 123 2 times, resulting in a remainder of 19.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 104 away from 123, we end up with 19.
Take the next digit (6) from the dividend and append it to 19, then repeat: 196 / 52

Step 4:
When dividing 196 by 52, we get 3 with a remainder of 40.
Put 3 as the next digit of the answer. 
Result so far: 123.0
Deduct 156 from 196 and we're left with 40.
Fetch the next digit (4) from the dividend, attach it to 40 and continue: 404 / 52

Moving on to step 5:
404 divided by 52 is 7 with a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 1237.0
If we take 364 away from 404, we end up with 40.
Grab the next digit (4) from the dividend, add it to 40, then carry on: 404 / 52

Step 6:
52 goes into 404 7 times with a remainder of 40.
The next digit of our result is 7. 
Result so far: 12377.0
Deduct 364 from 404 and we're left 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 7:
400 divided by 52 is 7 with a remainder of 36.
The next digit of our result is 7. 
Result so far: 12377.7
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.

Step 8:
52 goes into 360 6 times with a remainder of 48.
The next digit of our result is 6. 
Result so far: 12377.76
The remainder is 48 after subtracting 312 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 9:
If we divide 480 by 52, we get 9 and a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 12377.769
Deduct 468 from 480 and we're left 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 10:
The number 52 fits into 120 2 times, leaving a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 12377.7692
Deduct 104 from 120 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
160 divided by 52 is 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 12377.76923
The remainder is 4 after subtracting 156 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 12:
When dividing 40 by 52, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 12377.76923
Deduct 0 from 40 and we're left 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.

Advancing to step 13:
400 divided by 52 is 7 with a remainder of 36.
Put 7 as the next digit of the answer. 
Result so far: 12377.7692307
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.

Moving on to step 14:
The number 52 fits into 360 6 times, leaving a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 12377.76923076
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.

In conclusion, the division gives 12377.76923076 with a balance of 4.8e-08.
