63937597 ÷ 3 
We want to divide 63937597 by 3.

On to step 1:
If we divide 6 by 3, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 6 from 6 and we're left with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 3

Let's proceed to step 2:
3 can be fit into 3 1 times, resulting in a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we subtract 3 from 3, we get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 3

Step 3:
3 can be fit into 9 3 times, resulting in a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 213.0
Subtracting 9 from 9 leaves us with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 3

Let's proceed to step 4:
3 goes into 3 1 times with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 2131.0
Subtract 3 from 3 to get 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 3

Step 5:
7 divided by 3 is 2 with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 21312.0
The remainder is 1 after subtracting 6 from 7.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 3

Let's proceed to step 6:
3 goes into 15 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 213125.0
If we take 15 away from 15, we end up with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 3

Moving on to step 7:
9 divided by 3 is 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 2131253.0
The remainder is 0 after subtracting 9 from 9.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 3

Advancing to step 8:
When dividing 7 by 3, we get 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 21312532.0
Subtract 6 from 7 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 9:
If we divide 10 by 3, we get 3 and a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 21312532.3
Deduct 9 from 10 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 10:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 21312532.33
Deduct 9 from 10 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 21312532.33 with a balance of 0.001.
