Let's divide 63102386 by 431
Our goal is to divide 63102386 by 431.

Let's proceed to step 1:
If we divide 6 by 431, 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.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 431

Let's proceed to step 2:
63 divided by 431 is 0 with a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Take the next digit (1) from the dividend and append it to 63, then repeat: 631 / 431

Moving on to step 3:
431 goes into 631 1 times with a remainder of 200.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 431 from 631 leaves us with 200.
Include the next digit (0) from the dividend after 200, then repeat: 2000 / 431

Going ahead to step 4:
431 can be fit into 2000 4 times, resulting in a remainder of 276.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtract 1724 from 2000 to get 276.
Bring next digit (2) of the dividend behind the 276 and repeat the process: 2762 / 431

Step 5:
The number 431 fits into 2762 6 times, leaving a remainder of 176.
Put 6 as the next digit of the answer. 
Result so far: 146.0
Subtracting 2586 from 2762 leaves us with 176.
Take the next digit (3) from the dividend and append it to 176, then repeat: 1763 / 431

Let's proceed to step 6:
431 goes into 1763 4 times with a remainder of 39.
Record the quotient 4 as the next digit in the result. 
Result so far: 1464.0
Deduct 1724 from 1763 and we're left with 39.
Bring next digit (8) of the dividend behind the 39 and repeat the process: 398 / 431

Going ahead to step 7:
398 divided by 431 is 0 with a remainder of 398.
The next digit of our result is 0. 
Result so far: 14640.0
Deduct 0 from 398 and we're left with 398.
Include the next digit (6) from the dividend after 398, then repeat: 3986 / 431

Step 8:
If we divide 3986 by 431, we get 9 and a remainder of 107.
Record the quotient 9 as the next digit in the result. 
Result so far: 146409.0
The remainder is 107 after subtracting 3879 from 3986.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Let's proceed to step 9:
431 can be fit into 1070 2 times, resulting in a remainder of 208.
Record the quotient 2 as the next digit in the result. 
Result so far: 146409.2
If we take 862 away from 1070, we end up with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 10:
2080 divided by 431 is 4 with a remainder of 356.
Use 4 as the next digit of our solution. 
Result so far: 146409.24
Subtracting 1724 from 2080 leaves us with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Advancing to step 11:
If we divide 3560 by 431, we get 8 and a remainder of 112.
Use 8 as the next digit of our solution. 
Result so far: 146409.248
Subtract 3448 from 3560 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 12:
431 goes into 1120 2 times with a remainder of 258.
The number 2 becomes the next digit in our result. 
Result so far: 146409.2482
Deduct 862 from 1120 and we're left with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Let's proceed to step 13:
When dividing 2580 by 431, we get 5 with a remainder of 425.
Record the quotient 5 as the next digit in the result. 
Result so far: 146409.24825
Subtracting 2155 from 2580 leaves us with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Going ahead to step 14:
The number 431 fits into 4250 9 times, leaving a remainder of 371.
The number 9 becomes the next digit in our result. 
Result so far: 146409.248259
Subtract 3879 from 4250 to get 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

On to step 15:
431 goes into 3710 8 times with a remainder of 262.
Write down 8 as next digit of the result. 
Result so far: 146409.2482598
The remainder is 262 after subtracting 3448 from 3710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Let's proceed to step 16:
The number 431 fits into 2620 6 times, leaving a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 146409.24825986
The remainder is 34 after subtracting 2586 from 2620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

After the division, we end up with 146409.24825986 and a remainder of 3.4e-08.
