64849598 divided by 640 
Our goal is to divide 64849598 by 640.

Step 1:
6 divided by 640 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 640

Advancing to step 2:
640 can be fit into 64 0 times, resulting in a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Fetch the next digit (8) from the dividend, attach it to 64 and continue: 648 / 640

Advancing to step 3:
The number 640 fits into 648 1 times, leaving a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 8 after subtracting 640 from 648.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 640

Step 4:
84 divided by 640 is 0 with a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 84 leaves us with 84.
Include the next digit (9) from the dividend after 84, then repeat: 849 / 640

On to step 5:
640 can be fit into 849 1 times, resulting in a remainder of 209.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
If we subtract 640 from 849, we get 209.
Append the next digit (5) from the dividend to 209 and continue with: 2095 / 640

Let's proceed to step 6:
When dividing 2095 by 640, we get 3 with a remainder of 175.
Write down 3 as next digit of the result. 
Result so far: 1013.0
Subtracting 1920 from 2095 leaves us with 175.
Grab the next digit (9) from the dividend, add it to 175, then carry on: 1759 / 640

Moving on to step 7:
1759 divided by 640 is 2 with a remainder of 479.
The next digit of our result is 2. 
Result so far: 10132.0
Deduct 1280 from 1759 and we're left with 479.
Include the next digit (8) from the dividend after 479, then repeat: 4798 / 640

Going ahead to step 8:
When dividing 4798 by 640, we get 7 with a remainder of 318.
The number 7 becomes the next digit in our result. 
Result so far: 101327.0
Subtracting 4480 from 4798 leaves us with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Step 9:
The number 640 fits into 3180 4 times, leaving a remainder of 620.
The number 4 becomes the next digit in our result. 
Result so far: 101327.4
Subtract 2560 from 3180 to get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Going ahead to step 10:
6200 divided by 640 is 9 with a remainder of 440.
The number 9 becomes the next digit in our result. 
Result so far: 101327.49
Subtracting 5760 from 6200 leaves us with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Step 11:
If we divide 4400 by 640, we get 6 and a remainder of 560.
The next digit of our result is 6. 
Result so far: 101327.496
The remainder is 560 after subtracting 3840 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Advancing to step 12:
5600 divided by 640 is 8 with a remainder of 480.
Write down 8 as next digit of the result. 
Result so far: 101327.4968
Deduct 5120 from 5600 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 13:
The number 640 fits into 4800 7 times, leaving a remainder of 320.
The next digit of our result is 7. 
Result so far: 101327.49687
Deduct 4480 from 4800 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 14:
640 goes into 3200 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 101327.496875
Deduct 3200 from 3200 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.

Going ahead to step 15:
If we divide 0 by 640, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 101327.496875
If we subtract 0 from 0, we get 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 16:
0 divided by 640 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 101327.496875
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 101327.496875, and the remainder is 0.0.
