63839421 ÷ 115 
Our goal is to divide 63839421 by 115.

Advancing to step 1:
When dividing 6 by 115, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 115

Moving on to step 2:
If we divide 63 by 115, we get 0 and a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Grab the next digit (8) from the dividend, add it to 63, then carry on: 638 / 115

Let's proceed to step 3:
115 can be fit into 638 5 times, resulting in a remainder of 63.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 575 from 638 to get 63.
Fetch the next digit (3) from the dividend, attach it to 63 and continue: 633 / 115

Advancing to step 4:
The number 115 fits into 633 5 times, leaving a remainder of 58.
The next digit of our result is 5. 
Result so far: 55.0
Subtracting 575 from 633 leaves us with 58.
Append the next digit (9) from the dividend to 58 and continue with: 589 / 115

Let's proceed to step 5:
When dividing 589 by 115, we get 5 with a remainder of 14.
The next digit of our result is 5. 
Result so far: 555.0
If we take 575 away from 589, we end up with 14.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 115

Let's proceed to step 6:
The number 115 fits into 144 1 times, leaving a remainder of 29.
The next digit of our result is 1. 
Result so far: 5551.0
If we take 115 away from 144, we end up with 29.
Fetch the next digit (2) from the dividend, attach it to 29 and continue: 292 / 115

On to step 7:
115 goes into 292 2 times with a remainder of 62.
Record the quotient 2 as the next digit in the result. 
Result so far: 55512.0
The remainder is 62 after subtracting 230 from 292.
Include the next digit (1) from the dividend after 62, then repeat: 621 / 115

Going ahead to step 8:
The number 115 fits into 621 5 times, leaving a remainder of 46.
Record the quotient 5 as the next digit in the result. 
Result so far: 555125.0
If we take 575 away from 621, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 9:
If we divide 460 by 115, we get 4 and a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 555125.4
The remainder is 0 after subtracting 460 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
If we divide 0 by 115, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 555125.4
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
When dividing 0 by 115, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 555125.4
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 555125.4 with a balance of 0.0.
