782797 divided by 645 
We want to divide 782797 by 645.

Moving on to step 1:
If we divide 7 by 645, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 645

Moving on to step 2:
If we divide 78 by 645, we get 0 and a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Grab the next digit (2) from the dividend, add it to 78, then carry on: 782 / 645

Let's proceed to step 3:
When dividing 782 by 645, we get 1 with a remainder of 137.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 645 from 782 to get 137.
Bring next digit (7) of the dividend behind the 137 and repeat the process: 1377 / 645

Moving on to step 4:
1377 divided by 645 is 2 with a remainder of 87.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 1290 away from 1377, we end up with 87.
Fetch the next digit (9) from the dividend, attach it to 87 and continue: 879 / 645

Moving on to step 5:
If we divide 879 by 645, we get 1 and a remainder of 234.
Record the quotient 1 as the next digit in the result. 
Result so far: 121.0
Subtract 645 from 879 to get 234.
Take the next digit (7) from the dividend and append it to 234, then repeat: 2347 / 645

Let's proceed to step 6:
When dividing 2347 by 645, we get 3 with a remainder of 412.
Write down 3 as next digit of the result. 
Result so far: 1213.0
Deduct 1935 from 2347 and we're left with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Let's proceed to step 7:
The number 645 fits into 4120 6 times, leaving a remainder of 250.
The number 6 becomes the next digit in our result. 
Result so far: 1213.6
If we take 3870 away from 4120, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 8:
If we divide 2500 by 645, we get 3 and a remainder of 565.
Put 3 as the next digit of the answer. 
Result so far: 1213.63
Subtracting 1935 from 2500 leaves us with 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Step 9:
When dividing 5650 by 645, we get 8 with a remainder of 490.
Record the quotient 8 as the next digit in the result. 
Result so far: 1213.638
The remainder is 490 after subtracting 5160 from 5650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Advancing to step 10:
645 goes into 4900 7 times with a remainder of 385.
Put 7 as the next digit of the answer. 
Result so far: 1213.6387
Deduct 4515 from 4900 and we're left with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Step 11:
645 goes into 3850 5 times with a remainder of 625.
Record the quotient 5 as the next digit in the result. 
Result so far: 1213.63875
Deduct 3225 from 3850 and we're left with 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Going ahead to step 12:
645 goes into 6250 9 times with a remainder of 445.
The number 9 becomes the next digit in our result. 
Result so far: 1213.638759
Deduct 5805 from 6250 and we're left with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

On to step 13:
When dividing 4450 by 645, we get 6 with a remainder of 580.
Record the quotient 6 as the next digit in the result. 
Result so far: 1213.6387596
Deduct 3870 from 4450 and we're left with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Going ahead to step 14:
645 can be fit into 5800 8 times, resulting in a remainder of 640.
Record the quotient 8 as the next digit in the result. 
Result so far: 1213.63875968
Subtract 5160 from 5800 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

After the division, we end up with 1213.63875968 and a remainder of 6.4e-07.
