307090 ÷ 64 
We want to figure out the number of times 307090 can be divided by 64.

Step 1:
When dividing 3 by 64, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 64

Let's proceed to step 2:
64 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Fetch the next digit (7) from the dividend, attach it to 30 and continue: 307 / 64

On to step 3:
If we divide 307 by 64, we get 4 and a remainder of 51.
The next digit of our result is 4. 
Result so far: 4.0
If we take 256 away from 307, we end up with 51.
Fetch the next digit (0) from the dividend, attach it to 51 and continue: 510 / 64

On to step 4:
64 goes into 510 7 times with a remainder of 62.
Put 7 as the next digit of the answer. 
Result so far: 47.0
If we take 448 away from 510, we end up with 62.
Grab the next digit (9) from the dividend, add it to 62, then carry on: 629 / 64

Moving on to step 5:
If we divide 629 by 64, we get 9 and a remainder of 53.
Use 9 as the next digit of our solution. 
Result so far: 479.0
If we subtract 576 from 629, we get 53.
Include the next digit (0) from the dividend after 53, then repeat: 530 / 64

Moving on to step 6:
When dividing 530 by 64, we get 8 with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 4798.0
If we take 512 away from 530, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
When dividing 180 by 64, we get 2 with a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 4798.2
Deduct 128 from 180 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 8:
520 divided by 64 is 8 with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 4798.28
If we subtract 512 from 520, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
The number 64 fits into 80 1 times, leaving a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 4798.281
Deduct 64 from 80 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
64 can be fit into 160 2 times, resulting in a remainder of 32.
The next digit of our result is 2. 
Result so far: 4798.2812
Deduct 128 from 160 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 11:
320 divided by 64 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 4798.28125
The remainder is 0 after subtracting 320 from 320.
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 12:
64 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4798.28125
If we take 0 away from 0, we end up 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.

Let's proceed to step 13:
0 divided by 64 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4798.28125
If we take 0 away from 0, we end up 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 4798.28125, and the remainder is 0.0.
