We're dividing 64570872 by 139 
We want to divide 64570872 by 139.

Going ahead to step 1:
139 can be fit into 6 0 times, resulting in 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.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 139

Advancing to step 2:
The number 139 fits into 64 0 times, leaving a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Bring next digit (5) of the dividend behind the 64 and repeat the process: 645 / 139

Let's proceed to step 3:
139 can be fit into 645 4 times, resulting in a remainder of 89.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 89 after subtracting 556 from 645.
Fetch the next digit (7) from the dividend, attach it to 89 and continue: 897 / 139

On to step 4:
139 goes into 897 6 times with a remainder of 63.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
Subtracting 834 from 897 leaves us with 63.
Bring next digit (0) of the dividend behind the 63 and repeat the process: 630 / 139

Going ahead to step 5:
The number 139 fits into 630 4 times, leaving a remainder of 74.
The number 4 becomes the next digit in our result. 
Result so far: 464.0
Subtract 556 from 630 to get 74.
Include the next digit (8) from the dividend after 74, then repeat: 748 / 139

On to step 6:
139 can be fit into 748 5 times, resulting in a remainder of 53.
Use 5 as the next digit of our solution. 
Result so far: 4645.0
If we take 695 away from 748, we end up with 53.
Grab the next digit (7) from the dividend, add it to 53, then carry on: 537 / 139

Going ahead to step 7:
The number 139 fits into 537 3 times, leaving a remainder of 120.
Write down 3 as next digit of the result. 
Result so far: 46453.0
If we subtract 417 from 537, we get 120.
Include the next digit (2) from the dividend after 120, then repeat: 1202 / 139

Advancing to step 8:
139 can be fit into 1202 8 times, resulting in a remainder of 90.
Record the quotient 8 as the next digit in the result. 
Result so far: 464538.0
The remainder is 90 after subtracting 1112 from 1202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 9:
139 can be fit into 900 6 times, resulting in a remainder of 66.
Record the quotient 6 as the next digit in the result. 
Result so far: 464538.6
If we take 834 away from 900, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 10:
139 can be fit into 660 4 times, resulting in a remainder of 104.
Put 4 as the next digit of the answer. 
Result so far: 464538.64
If we subtract 556 from 660, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 11:
139 goes into 1040 7 times with a remainder of 67.
The number 7 becomes the next digit in our result. 
Result so far: 464538.647
Subtract 973 from 1040 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 12:
If we divide 670 by 139, we get 4 and a remainder of 114.
Record the quotient 4 as the next digit in the result. 
Result so far: 464538.6474
Subtracting 556 from 670 leaves us with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Step 13:
1140 divided by 139 is 8 with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 464538.64748
Subtracting 1112 from 1140 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 14:
280 divided by 139 is 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 464538.647482
If we take 278 away from 280, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 15:
If we divide 20 by 139, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 464538.647482
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 16:
The number 139 fits into 200 1 times, leaving a remainder of 61.
The number 1 becomes the next digit in our result. 
Result so far: 464538.64748201
If we take 139 away from 200, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Our division results in 464538.64748201 with a remaining 6.1e-08.
