64945674 ÷ 734 
We want to figure out the number of times 64945674 can be divided by 734.

Going ahead to step 1:
The number 734 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 734

Step 2:
64 divided by 734 is 0 with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Include the next digit (9) from the dividend after 64, then repeat: 649 / 734

Moving on to step 3:
649 divided by 734 is 0 with a remainder of 649.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 649, we get 649.
Bring next digit (4) of the dividend behind the 649 and repeat the process: 6494 / 734

On to step 4:
734 goes into 6494 8 times with a remainder of 622.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 5872 from 6494, we get 622.
Include the next digit (5) from the dividend after 622, then repeat: 6225 / 734

Going ahead to step 5:
734 can be fit into 6225 8 times, resulting in a remainder of 353.
Use 8 as the next digit of our solution. 
Result so far: 88.0
The remainder is 353 after subtracting 5872 from 6225.
Append the next digit (6) from the dividend to 353 and continue with: 3536 / 734

Advancing to step 6:
734 can be fit into 3536 4 times, resulting in a remainder of 600.
Record the quotient 4 as the next digit in the result. 
Result so far: 884.0
If we subtract 2936 from 3536, we get 600.
Include the next digit (7) from the dividend after 600, then repeat: 6007 / 734

Going ahead to step 7:
734 can be fit into 6007 8 times, resulting in a remainder of 135.
Write down 8 as next digit of the result. 
Result so far: 8848.0
Subtracting 5872 from 6007 leaves us with 135.
Fetch the next digit (4) from the dividend, attach it to 135 and continue: 1354 / 734

Advancing to step 8:
The number 734 fits into 1354 1 times, leaving a remainder of 620.
Record the quotient 1 as the next digit in the result. 
Result so far: 88481.0
Deduct 734 from 1354 and we're left with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Let's proceed to step 9:
734 goes into 6200 8 times with a remainder of 328.
Put 8 as the next digit of the answer. 
Result so far: 88481.8
If we subtract 5872 from 6200, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Step 10:
The number 734 fits into 3280 4 times, leaving a remainder of 344.
The number 4 becomes the next digit in our result. 
Result so far: 88481.84
If we take 2936 away from 3280, we end up with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Advancing to step 11:
734 goes into 3440 4 times with a remainder of 504.
Use 4 as the next digit of our solution. 
Result so far: 88481.844
Deduct 2936 from 3440 and we're left with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

The final result is 88481.844 with a remainder of 0.0504.
