We divide 64740997 by 640
Our goal is to divide 64740997 by 640.

Step 1:
640 goes into 6 0 times 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.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 640

Advancing to step 2:
The number 640 fits into 64 0 times, leaving a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Take the next digit (7) from the dividend and append it to 64, then repeat: 647 / 640

Moving on to step 3:
640 goes into 647 1 times with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 640 from 647 and we're left with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 640

Advancing to step 4:
640 can be fit into 74 0 times, resulting in a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 74, we get 74.
Fetch the next digit (0) from the dividend, attach it to 74 and continue: 740 / 640

Let's proceed to step 5:
The number 640 fits into 740 1 times, leaving a remainder of 100.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
Subtract 640 from 740 to get 100.
Append the next digit (9) from the dividend to 100 and continue with: 1009 / 640

On to step 6:
If we divide 1009 by 640, we get 1 and a remainder of 369.
Put 1 as the next digit of the answer. 
Result so far: 1011.0
Deduct 640 from 1009 and we're left with 369.
Fetch the next digit (9) from the dividend, attach it to 369 and continue: 3699 / 640

Going ahead to step 7:
The number 640 fits into 3699 5 times, leaving a remainder of 499.
Put 5 as the next digit of the answer. 
Result so far: 10115.0
Subtract 3200 from 3699 to get 499.
Take the next digit (7) from the dividend and append it to 499, then repeat: 4997 / 640

Going ahead to step 8:
640 can be fit into 4997 7 times, resulting in a remainder of 517.
Record the quotient 7 as the next digit in the result. 
Result so far: 101157.0
Subtracting 4480 from 4997 leaves us with 517.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

Advancing to step 9:
If we divide 5170 by 640, we get 8 and a remainder of 50.
Put 8 as the next digit of the answer. 
Result so far: 101157.8
Subtracting 5120 from 5170 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 10:
640 can be fit into 500 0 times, resulting in a remainder of 500.
The number 0 becomes the next digit in our result. 
Result so far: 101157.8
Subtract 0 from 500 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Step 11:
If we divide 5000 by 640, we get 7 and a remainder of 520.
The number 7 becomes the next digit in our result. 
Result so far: 101157.807
The remainder is 520 after subtracting 4480 from 5000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 12:
When dividing 5200 by 640, we get 8 with a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 101157.8078
Subtract 5120 from 5200 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 13:
800 divided by 640 is 1 with a remainder of 160.
Write down 1 as next digit of the result. 
Result so far: 101157.80781
Subtract 640 from 800 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 14:
640 goes into 1600 2 times with a remainder of 320.
Use 2 as the next digit of our solution. 
Result so far: 101157.807812
The remainder is 320 after subtracting 1280 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 15:
When dividing 3200 by 640, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 101157.8078125
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.

Step 16:
The number 640 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 101157.8078125
Deduct 0 from 0 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.

The final result is 101157.8078125 with a remainder of 0.0.
