52780523 divided by 640 
We're looking to find how many times 640 goes into 52780523.

Going ahead to step 1:
The number 640 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 640

Step 2:
The number 640 fits into 52 0 times, leaving a remainder of 52.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 52, we end up with 52.
Bring next digit (7) of the dividend behind the 52 and repeat the process: 527 / 640

Step 3:
527 divided by 640 is 0 with a remainder of 527.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 527 to get 527.
Bring next digit (8) of the dividend behind the 527 and repeat the process: 5278 / 640

Step 4:
640 goes into 5278 8 times with a remainder of 158.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 5120 from 5278 leaves us with 158.
Grab the next digit (0) from the dividend, add it to 158, then carry on: 1580 / 640

On to step 5:
1580 divided by 640 is 2 with a remainder of 300.
Write down 2 as next digit of the result. 
Result so far: 82.0
The remainder is 300 after subtracting 1280 from 1580.
Grab the next digit (5) from the dividend, add it to 300, then carry on: 3005 / 640

Moving on to step 6:
640 can be fit into 3005 4 times, resulting in a remainder of 445.
Use 4 as the next digit of our solution. 
Result so far: 824.0
Subtract 2560 from 3005 to get 445.
Bring next digit (2) of the dividend behind the 445 and repeat the process: 4452 / 640

Advancing to step 7:
4452 divided by 640 is 6 with a remainder of 612.
The number 6 becomes the next digit in our result. 
Result so far: 8246.0
If we subtract 3840 from 4452, we get 612.
Fetch the next digit (3) from the dividend, attach it to 612 and continue: 6123 / 640

Moving on to step 8:
If we divide 6123 by 640, we get 9 and a remainder of 363.
The number 9 becomes the next digit in our result. 
Result so far: 82469.0
Deduct 5760 from 6123 and we're left with 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Step 9:
When dividing 3630 by 640, we get 5 with a remainder of 430.
The number 5 becomes the next digit in our result. 
Result so far: 82469.5
The remainder is 430 after subtracting 3200 from 3630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Moving on to step 10:
4300 divided by 640 is 6 with a remainder of 460.
Use 6 as the next digit of our solution. 
Result so far: 82469.56
Subtract 3840 from 4300 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 11:
When dividing 4600 by 640, we get 7 with a remainder of 120.
Record the quotient 7 as the next digit in the result. 
Result so far: 82469.567
Deduct 4480 from 4600 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 12:
640 goes into 1200 1 times with a remainder of 560.
The next digit of our result is 1. 
Result so far: 82469.5671
If we subtract 640 from 1200, 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.

Advancing to step 13:
640 can be fit into 5600 8 times, resulting in a remainder of 480.
Record the quotient 8 as the next digit in the result. 
Result so far: 82469.56718
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 14:
640 goes into 4800 7 times with a remainder of 320.
Write down 7 as next digit of the result. 
Result so far: 82469.567187
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.

Let's proceed to step 15:
3200 divided by 640 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 82469.5671875
Subtract 3200 from 3200 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.

On to step 16:
The number 640 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 82469.5671875
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 quotient of the division is 82469.5671875, and the remainder is 0.0.
