We're dividing 638463 by 52 
Let's see how many times 52 fits into 638463.

Step 1:
If we divide 6 by 52, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 52

Going ahead to step 2:
The number 52 fits into 63 1 times, leaving a remainder of 11.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 52 from 63 and we're left with 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 52

Step 3:
118 divided by 52 is 2 with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 14 after subtracting 104 from 118.
Bring next digit (4) of the dividend behind the 14 and repeat the process: 144 / 52

Moving on to step 4:
When dividing 144 by 52, we get 2 with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 122.0
Subtracting 104 from 144 leaves us with 40.
Append the next digit (6) from the dividend to 40 and continue with: 406 / 52

Step 5:
52 can be fit into 406 7 times, resulting in a remainder of 42.
Put 7 as the next digit of the answer. 
Result so far: 1227.0
If we take 364 away from 406, we end up with 42.
Append the next digit (3) from the dividend to 42 and continue with: 423 / 52

Let's proceed to step 6:
52 goes into 423 8 times with a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 12278.0
Deduct 416 from 423 and we're left 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.

Let's proceed to step 7:
When dividing 70 by 52, we get 1 with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 12278.1
Subtracting 52 from 70 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 8:
The number 52 fits into 180 3 times, leaving a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 12278.13
The remainder is 24 after subtracting 156 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
240 divided by 52 is 4 with a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 12278.134
The remainder is 32 after subtracting 208 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 10:
52 can be fit into 320 6 times, resulting in a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 12278.1346
If we take 312 away from 320, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
The number 52 fits into 80 1 times, leaving a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 12278.13461
Deduct 52 from 80 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 12:
280 divided by 52 is 5 with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 12278.134615
Deduct 260 from 280 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 13:
When dividing 200 by 52, we get 3 with a remainder of 44.
Put 3 as the next digit of the answer. 
Result so far: 12278.1346153
The remainder is 44 after subtracting 156 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 14:
If we divide 440 by 52, we get 8 and a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 12278.13461538
Subtract 416 from 440 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 12278.13461538 with a remainder of 2.4e-08.
