Let's divide 640493 by 52
We want to figure out the number of times 640493 can be divided by 52.

Let's proceed to step 1:
When dividing 6 by 52, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 52

Moving on to step 2:
The number 52 fits into 64 1 times, leaving a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 52 from 64, we get 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 52

Step 3:
If we divide 120 by 52, we get 2 and a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 16 after subtracting 104 from 120.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 52

Let's proceed to step 4:
52 goes into 164 3 times with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 123.0
If we subtract 156 from 164, we get 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 52

Moving on to step 5:
The number 52 fits into 89 1 times, leaving a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 1231.0
Subtract 52 from 89 to get 37.
Bring next digit (3) of the dividend behind the 37 and repeat the process: 373 / 52

Moving on to step 6:
The number 52 fits into 373 7 times, leaving a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 12317.0
Subtracting 364 from 373 leaves us 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.

Moving on to step 7:
If we divide 90 by 52, we get 1 and a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 12317.1
If we subtract 52 from 90, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 8:
380 divided by 52 is 7 with a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 12317.17
Subtract 364 from 380 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.

Going ahead to step 9:
When dividing 160 by 52, we get 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 12317.173
Deduct 156 from 160 and we're left 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 10:
40 divided by 52 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 12317.173
Subtracting 0 from 40 leaves us 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.

Let's proceed 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: 12317.17307
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 12:
52 can be fit into 360 6 times, resulting in a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 12317.173076
Subtract 312 from 360 to 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.

Advancing to step 13:
52 can be fit into 480 9 times, resulting in a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 12317.1730769
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.

Advancing to step 14:
If we divide 120 by 52, we get 2 and a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 12317.17307692
If we take 104 away from 120, we end up 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.

The final outcome is 12317.17307692, with a leftover of 1.6e-08.
