We divide 64251127 by 639
We want to divide 64251127 by 639.

Moving on to step 1:
639 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 639

Advancing to step 2:
When dividing 64 by 639, we get 0 with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Append the next digit (2) from the dividend to 64 and continue with: 642 / 639

Advancing to step 3:
When dividing 642 by 639, we get 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 639 away from 642, we end up with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 639

Let's proceed to step 4:
639 can be fit into 35 0 times, resulting in a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 35, we get 35.
Append the next digit (1) from the dividend to 35 and continue with: 351 / 639

Advancing to step 5:
The number 639 fits into 351 0 times, leaving a remainder of 351.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
If we subtract 0 from 351, we get 351.
Take the next digit (1) from the dividend and append it to 351, then repeat: 3511 / 639

Going ahead to step 6:
639 can be fit into 3511 5 times, resulting in a remainder of 316.
Use 5 as the next digit of our solution. 
Result so far: 1005.0
Deduct 3195 from 3511 and we're left with 316.
Fetch the next digit (2) from the dividend, attach it to 316 and continue: 3162 / 639

On to step 7:
639 can be fit into 3162 4 times, resulting in a remainder of 606.
Write down 4 as next digit of the result. 
Result so far: 10054.0
If we subtract 2556 from 3162, we get 606.
Bring next digit (7) of the dividend behind the 606 and repeat the process: 6067 / 639

Advancing to step 8:
6067 divided by 639 is 9 with a remainder of 316.
The number 9 becomes the next digit in our result. 
Result so far: 100549.0
If we take 5751 away from 6067, we end up with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Let's proceed to step 9:
3160 divided by 639 is 4 with a remainder of 604.
Use 4 as the next digit of our solution. 
Result so far: 100549.4
The remainder is 604 after subtracting 2556 from 3160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Let's proceed to step 10:
639 can be fit into 6040 9 times, resulting in a remainder of 289.
The next digit of our result is 9. 
Result so far: 100549.49
If we subtract 5751 from 6040, we get 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Advancing to step 11:
If we divide 2890 by 639, we get 4 and a remainder of 334.
Put 4 as the next digit of the answer. 
Result so far: 100549.494
Subtract 2556 from 2890 to get 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

On to step 12:
639 can be fit into 3340 5 times, resulting in a remainder of 145.
Use 5 as the next digit of our solution. 
Result so far: 100549.4945
If we subtract 3195 from 3340, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Going ahead to step 13:
When dividing 1450 by 639, we get 2 with a remainder of 172.
The number 2 becomes the next digit in our result. 
Result so far: 100549.49452
If we subtract 1278 from 1450, we get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Let's proceed to step 14:
639 can be fit into 1720 2 times, resulting in a remainder of 442.
Write down 2 as next digit of the result. 
Result so far: 100549.494522
If we take 1278 away from 1720, we end up with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

In conclusion, the division gives 100549.494522 with a balance of 4.42e-05.
