75749977 ÷ 649 
We're looking to find how many times 649 goes into 75749977.

Moving on to step 1:
If we divide 7 by 649, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 649

On to step 2:
75 divided by 649 is 0 with a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 75, we end up with 75.
Fetch the next digit (7) from the dividend, attach it to 75 and continue: 757 / 649

Step 3:
The number 649 fits into 757 1 times, leaving a remainder of 108.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 649 from 757 to get 108.
Append the next digit (4) from the dividend to 108 and continue with: 1084 / 649

Step 4:
The number 649 fits into 1084 1 times, leaving a remainder of 435.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we take 649 away from 1084, we end up with 435.
Bring next digit (9) of the dividend behind the 435 and repeat the process: 4359 / 649

Going ahead to step 5:
4359 divided by 649 is 6 with a remainder of 465.
Use 6 as the next digit of our solution. 
Result so far: 116.0
If we take 3894 away from 4359, we end up with 465.
Bring next digit (9) of the dividend behind the 465 and repeat the process: 4659 / 649

Going ahead to step 6:
The number 649 fits into 4659 7 times, leaving a remainder of 116.
Put 7 as the next digit of the answer. 
Result so far: 1167.0
If we subtract 4543 from 4659, we get 116.
Append the next digit (7) from the dividend to 116 and continue with: 1167 / 649

Advancing to step 7:
649 goes into 1167 1 times with a remainder of 518.
The number 1 becomes the next digit in our result. 
Result so far: 11671.0
If we subtract 649 from 1167, we get 518.
Grab the next digit (7) from the dividend, add it to 518, then carry on: 5187 / 649

Advancing to step 8:
649 can be fit into 5187 7 times, resulting in a remainder of 644.
The next digit of our result is 7. 
Result so far: 116717.0
Subtracting 4543 from 5187 leaves us with 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Advancing to step 9:
6440 divided by 649 is 9 with a remainder of 599.
The next digit of our result is 9. 
Result so far: 116717.9
Subtract 5841 from 6440 to get 599.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

Let's proceed to step 10:
649 goes into 5990 9 times with a remainder of 149.
Write down 9 as next digit of the result. 
Result so far: 116717.99
Deduct 5841 from 5990 and we're left with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

After the division, we end up with 116717.99 and a remainder of 0.149.
