Let's divide 38520597 by 649
We want to divide 38520597 by 649.

Advancing to step 1:
649 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 649

On to step 2:
If we divide 38 by 649, we get 0 and a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Grab the next digit (5) from the dividend, add it to 38, then carry on: 385 / 649

Step 3:
649 can be fit into 385 0 times, resulting in a remainder of 385.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 385 and we're left with 385.
Include the next digit (2) from the dividend after 385, then repeat: 3852 / 649

On to step 4:
When dividing 3852 by 649, we get 5 with a remainder of 607.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 3245 from 3852 to get 607.
Bring next digit (0) of the dividend behind the 607 and repeat the process: 6070 / 649

Advancing to step 5:
When dividing 6070 by 649, we get 9 with a remainder of 229.
The next digit of our result is 9. 
Result so far: 59.0
If we take 5841 away from 6070, we end up with 229.
Take the next digit (5) from the dividend and append it to 229, then repeat: 2295 / 649

Advancing to step 6:
If we divide 2295 by 649, we get 3 and a remainder of 348.
The number 3 becomes the next digit in our result. 
Result so far: 593.0
Subtract 1947 from 2295 to get 348.
Fetch the next digit (9) from the dividend, attach it to 348 and continue: 3489 / 649

Advancing to step 7:
649 goes into 3489 5 times with a remainder of 244.
The next digit of our result is 5. 
Result so far: 5935.0
If we take 3245 away from 3489, we end up with 244.
Fetch the next digit (7) from the dividend, attach it to 244 and continue: 2447 / 649

Going ahead to step 8:
The number 649 fits into 2447 3 times, leaving a remainder of 500.
Use 3 as the next digit of our solution. 
Result so far: 59353.0
If we subtract 1947 from 2447, we 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.

Moving on to step 9:
649 can be fit into 5000 7 times, resulting in a remainder of 457.
Record the quotient 7 as the next digit in the result. 
Result so far: 59353.7
Subtract 4543 from 5000 to get 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Going ahead to step 10:
649 can be fit into 4570 7 times, resulting in a remainder of 27.
The next digit of our result is 7. 
Result so far: 59353.77
Subtract 4543 from 4570 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The final result is 59353.77 with a remainder of 0.027.
