64989859 divided by 140 
We want to divide 64989859 by 140.

Step 1:
6 divided by 140 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 140

Let's proceed to step 2:
140 goes into 64 0 times with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Bring next digit (9) of the dividend behind the 64 and repeat the process: 649 / 140

Advancing to step 3:
If we divide 649 by 140, we get 4 and a remainder of 89.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 560 from 649, we get 89.
Append the next digit (8) from the dividend to 89 and continue with: 898 / 140

Step 4:
898 divided by 140 is 6 with a remainder of 58.
Put 6 as the next digit of the answer. 
Result so far: 46.0
Deduct 840 from 898 and we're left with 58.
Take the next digit (9) from the dividend and append it to 58, then repeat: 589 / 140

Going ahead to step 5:
140 goes into 589 4 times with a remainder of 29.
Write down 4 as next digit of the result. 
Result so far: 464.0
If we take 560 away from 589, we end up with 29.
Bring next digit (8) of the dividend behind the 29 and repeat the process: 298 / 140

Let's proceed to step 6:
298 divided by 140 is 2 with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 4642.0
If we subtract 280 from 298, we get 18.
Include the next digit (5) from the dividend after 18, then repeat: 185 / 140

Let's proceed to step 7:
If we divide 185 by 140, we get 1 and a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 46421.0
Subtracting 140 from 185 leaves us with 45.
Append the next digit (9) from the dividend to 45 and continue with: 459 / 140

Let's proceed to step 8:
If we divide 459 by 140, we get 3 and a remainder of 39.
The next digit of our result is 3. 
Result so far: 464213.0
If we take 420 away from 459, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 9:
When dividing 390 by 140, we get 2 with a remainder of 110.
Put 2 as the next digit of the answer. 
Result so far: 464213.2
The remainder is 110 after subtracting 280 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 10:
1100 divided by 140 is 7 with a remainder of 120.
Use 7 as the next digit of our solution. 
Result so far: 464213.27
If we subtract 980 from 1100, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 11:
When dividing 1200 by 140, we get 8 with a remainder of 80.
Put 8 as the next digit of the answer. 
Result so far: 464213.278
If we take 1120 away from 1200, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 12:
800 divided by 140 is 5 with a remainder of 100.
The next digit of our result is 5. 
Result so far: 464213.2785
If we subtract 700 from 800, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 13:
The number 140 fits into 1000 7 times, leaving a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 464213.27857
The remainder is 20 after subtracting 980 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
The number 140 fits into 200 1 times, leaving a remainder of 60.
The number 1 becomes the next digit in our result. 
Result so far: 464213.278571
If we take 140 away from 200, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 15:
The number 140 fits into 600 4 times, leaving a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 464213.2785714
If we subtract 560 from 600, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 16:
If we divide 400 by 140, we get 2 and a remainder of 120.
The next digit of our result is 2. 
Result so far: 464213.27857142
If we subtract 280 from 400, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The final result is 464213.27857142 with a remainder of 1.2e-07.
