We divide 53710044 by 640
We're looking to find how many times 640 goes into 53710044.

Going ahead to step 1:
640 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 640

On to step 2:
When dividing 53 by 640, we get 0 with a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Grab the next digit (7) from the dividend, add it to 53, then carry on: 537 / 640

Advancing to step 3:
If we divide 537 by 640, we get 0 and a remainder of 537.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 537 and we're left with 537.
Include the next digit (1) from the dividend after 537, then repeat: 5371 / 640

Advancing to step 4:
The number 640 fits into 5371 8 times, leaving a remainder of 251.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 251 after subtracting 5120 from 5371.
Fetch the next digit (0) from the dividend, attach it to 251 and continue: 2510 / 640

Step 5:
2510 divided by 640 is 3 with a remainder of 590.
The next digit of our result is 3. 
Result so far: 83.0
Subtracting 1920 from 2510 leaves us with 590.
Append the next digit (0) from the dividend to 590 and continue with: 5900 / 640

On to step 6:
5900 divided by 640 is 9 with a remainder of 140.
Put 9 as the next digit of the answer. 
Result so far: 839.0
Deduct 5760 from 5900 and we're left with 140.
Take the next digit (4) from the dividend and append it to 140, then repeat: 1404 / 640

Let's proceed to step 7:
640 can be fit into 1404 2 times, resulting in a remainder of 124.
The next digit of our result is 2. 
Result so far: 8392.0
If we take 1280 away from 1404, we end up with 124.
Fetch the next digit (4) from the dividend, attach it to 124 and continue: 1244 / 640

Advancing to step 8:
640 goes into 1244 1 times with a remainder of 604.
The next digit of our result is 1. 
Result so far: 83921.0
If we take 640 away from 1244, we end up with 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Let's proceed to step 9:
The number 640 fits into 6040 9 times, leaving a remainder of 280.
Use 9 as the next digit of our solution. 
Result so far: 83921.9
Subtract 5760 from 6040 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 10:
If we divide 2800 by 640, we get 4 and a remainder of 240.
Put 4 as the next digit of the answer. 
Result so far: 83921.94
The remainder is 240 after subtracting 2560 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 11:
If we divide 2400 by 640, we get 3 and a remainder of 480.
Put 3 as the next digit of the answer. 
Result so far: 83921.943
Deduct 1920 from 2400 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.

Step 12:
The number 640 fits into 4800 7 times, leaving a remainder of 320.
The next digit of our result is 7. 
Result so far: 83921.9437
If we take 4480 away from 4800, we end up 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.

Moving on to step 13:
If we divide 3200 by 640, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 83921.94375
If we take 3200 away from 3200, 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.

Moving on to step 14:
640 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 83921.94375
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 15:
640 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 83921.94375
Subtract 0 from 0 to 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 final result is 83921.94375 with a remainder of 0.0.
