We look at the division of 639111 by 64 
Let's see how many times 64 fits into 639111.

Let's proceed to step 1:
6 divided by 64 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 64

Let's proceed to step 2:
64 goes into 63 0 times with a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Take the next digit (9) from the dividend and append it to 63, then repeat: 639 / 64

Going ahead to step 3:
64 goes into 639 9 times with a remainder of 63.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 576 from 639 and we're left with 63.
Take the next digit (1) from the dividend and append it to 63, then repeat: 631 / 64

Advancing to step 4:
64 can be fit into 631 9 times, resulting in a remainder of 55.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
Subtracting 576 from 631 leaves us with 55.
Append the next digit (1) from the dividend to 55 and continue with: 551 / 64

Moving on to step 5:
If we divide 551 by 64, we get 8 and a remainder of 39.
Put 8 as the next digit of the answer. 
Result so far: 998.0
Subtracting 512 from 551 leaves us with 39.
Include the next digit (1) from the dividend after 39, then repeat: 391 / 64

Advancing to step 6:
64 can be fit into 391 6 times, resulting in a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 9986.0
Subtracting 384 from 391 leaves us 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.

On to step 7:
The number 64 fits into 70 1 times, leaving a remainder of 6.
The next digit of our result is 1. 
Result so far: 9986.1
Subtract 64 from 70 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
If we divide 60 by 64, we get 0 and a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 9986.1
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
When dividing 600 by 64, we get 9 with a remainder of 24.
The next digit of our result is 9. 
Result so far: 9986.109
If we subtract 576 from 600, we 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.

Let's proceed to step 10:
240 divided by 64 is 3 with a remainder of 48.
Put 3 as the next digit of the answer. 
Result so far: 9986.1093
If we subtract 192 from 240, we 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.

Step 11:
When dividing 480 by 64, we get 7 with a remainder of 32.
The next digit of our result is 7. 
Result so far: 9986.10937
Deduct 448 from 480 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 12:
If we divide 320 by 64, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 9986.109375
Deduct 320 from 320 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.

Advancing to step 13:
When dividing 0 by 64, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 9986.109375
If we take 0 away from 0, we end up 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.

Step 14:
64 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9986.109375
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 9986.109375 with a balance of 0.0.
