We look at the division of 64002064 by 139 
Our goal is to divide 64002064 by 139.

Advancing to step 1:
When dividing 6 by 139, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 139

Step 2:
The number 139 fits into 64 0 times, leaving a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Bring next digit (0) of the dividend behind the 64 and repeat the process: 640 / 139

On to step 3:
If we divide 640 by 139, we get 4 and a remainder of 84.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 556 from 640, we get 84.
Bring next digit (0) of the dividend behind the 84 and repeat the process: 840 / 139

Step 4:
840 divided by 139 is 6 with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 46.0
Subtract 834 from 840 to get 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 139

Step 5:
When dividing 62 by 139, we get 0 with a remainder of 62.
The number 0 becomes the next digit in our result. 
Result so far: 460.0
Subtracting 0 from 62 leaves us with 62.
Take the next digit (0) from the dividend and append it to 62, then repeat: 620 / 139

On to step 6:
The number 139 fits into 620 4 times, leaving a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 4604.0
If we take 556 away from 620, we end up with 64.
Include the next digit (6) from the dividend after 64, then repeat: 646 / 139

Going ahead to step 7:
If we divide 646 by 139, we get 4 and a remainder of 90.
Write down 4 as next digit of the result. 
Result so far: 46044.0
If we take 556 away from 646, we end up with 90.
Include the next digit (4) from the dividend after 90, then repeat: 904 / 139

Moving on to step 8:
904 divided by 139 is 6 with a remainder of 70.
Record the quotient 6 as the next digit in the result. 
Result so far: 460446.0
Subtract 834 from 904 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 9:
When dividing 700 by 139, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 460446.5
Deduct 695 from 700 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 10:
139 can be fit into 50 0 times, resulting in a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 460446.5
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
If we divide 500 by 139, we get 3 and a remainder of 83.
Put 3 as the next digit of the answer. 
Result so far: 460446.503
Deduct 417 from 500 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 12:
830 divided by 139 is 5 with a remainder of 135.
Record the quotient 5 as the next digit in the result. 
Result so far: 460446.5035
If we subtract 695 from 830, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

On to step 13:
The number 139 fits into 1350 9 times, leaving a remainder of 99.
The next digit of our result is 9. 
Result so far: 460446.50359
The remainder is 99 after subtracting 1251 from 1350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Going ahead to step 14:
139 can be fit into 990 7 times, resulting in a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 460446.503597
Deduct 973 from 990 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 15:
When dividing 170 by 139, we get 1 with a remainder of 31.
The next digit of our result is 1. 
Result so far: 460446.5035971
If we take 139 away from 170, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 16:
The number 139 fits into 310 2 times, leaving a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 460446.50359712
The remainder is 32 after subtracting 278 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 460446.50359712 and a remainder of 3.2e-08.
