97765374 divided by 640 
We want to divide 97765374 by 640.

Going ahead to step 1:
If we divide 9 by 640, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 640

On to step 2:
When dividing 97 by 640, we get 0 with a remainder of 97.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 97, we end up with 97.
Bring next digit (7) of the dividend behind the 97 and repeat the process: 977 / 640

Let's proceed to step 3:
640 can be fit into 977 1 times, resulting in a remainder of 337.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 640 from 977 and we're left with 337.
Take the next digit (6) from the dividend and append it to 337, then repeat: 3376 / 640

Moving on to step 4:
3376 divided by 640 is 5 with a remainder of 176.
The next digit of our result is 5. 
Result so far: 15.0
Subtracting 3200 from 3376 leaves us with 176.
Take the next digit (5) from the dividend and append it to 176, then repeat: 1765 / 640

Step 5:
640 can be fit into 1765 2 times, resulting in a remainder of 485.
Use 2 as the next digit of our solution. 
Result so far: 152.0
Subtracting 1280 from 1765 leaves us with 485.
Take the next digit (3) from the dividend and append it to 485, then repeat: 4853 / 640

Going ahead to step 6:
When dividing 4853 by 640, we get 7 with a remainder of 373.
Record the quotient 7 as the next digit in the result. 
Result so far: 1527.0
Subtract 4480 from 4853 to get 373.
Fetch the next digit (7) from the dividend, attach it to 373 and continue: 3737 / 640

Going ahead to step 7:
If we divide 3737 by 640, we get 5 and a remainder of 537.
The next digit of our result is 5. 
Result so far: 15275.0
Subtract 3200 from 3737 to get 537.
Grab the next digit (4) from the dividend, add it to 537, then carry on: 5374 / 640

Step 8:
640 can be fit into 5374 8 times, resulting in a remainder of 254.
Record the quotient 8 as the next digit in the result. 
Result so far: 152758.0
If we subtract 5120 from 5374, we get 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

On to step 9:
When dividing 2540 by 640, we get 3 with a remainder of 620.
Record the quotient 3 as the next digit in the result. 
Result so far: 152758.3
Deduct 1920 from 2540 and we're left with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Let's proceed to step 10:
640 can be fit into 6200 9 times, resulting in a remainder of 440.
The next digit of our result is 9. 
Result so far: 152758.39
Subtract 5760 from 6200 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 11:
The number 640 fits into 4400 6 times, leaving a remainder of 560.
The number 6 becomes the next digit in our result. 
Result so far: 152758.396
If we subtract 3840 from 4400, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 12:
If we divide 5600 by 640, we get 8 and a remainder of 480.
Write down 8 as next digit of the result. 
Result so far: 152758.3968
The remainder is 480 after subtracting 5120 from 5600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 13:
640 goes into 4800 7 times with a remainder of 320.
The number 7 becomes the next digit in our result. 
Result so far: 152758.39687
If we subtract 4480 from 4800, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 14:
640 can be fit into 3200 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 152758.396875
Subtracting 3200 from 3200 leaves us 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.

Advancing to step 15:
If we divide 0 by 640, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 152758.396875
If we take 0 away from 0, we end up 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:
If we divide 0 by 640, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 152758.396875
Subtracting 0 from 0 leaves us 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.

After the division, we end up with 152758.396875 and a remainder of 0.0.
