We're dividing 90936124 by 640 
We want to figure out the number of times 90936124 can be divided by 640.

Step 1:
640 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 640

Moving on to step 2:
If we divide 90 by 640, we get 0 and a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Bring next digit (9) of the dividend behind the 90 and repeat the process: 909 / 640

Step 3:
The number 640 fits into 909 1 times, leaving a remainder of 269.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 640 from 909 and we're left with 269.
Include the next digit (3) from the dividend after 269, then repeat: 2693 / 640

Let's proceed to step 4:
640 can be fit into 2693 4 times, resulting in a remainder of 133.
Put 4 as the next digit of the answer. 
Result so far: 14.0
The remainder is 133 after subtracting 2560 from 2693.
Append the next digit (6) from the dividend to 133 and continue with: 1336 / 640

Let's proceed to step 5:
When dividing 1336 by 640, we get 2 with a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 142.0
The remainder is 56 after subtracting 1280 from 1336.
Take the next digit (1) from the dividend and append it to 56, then repeat: 561 / 640

On to step 6:
640 can be fit into 561 0 times, resulting in a remainder of 561.
Use 0 as the next digit of our solution. 
Result so far: 1420.0
Subtract 0 from 561 to get 561.
Include the next digit (2) from the dividend after 561, then repeat: 5612 / 640

Moving on to step 7:
5612 divided by 640 is 8 with a remainder of 492.
The next digit of our result is 8. 
Result so far: 14208.0
The remainder is 492 after subtracting 5120 from 5612.
Bring next digit (4) of the dividend behind the 492 and repeat the process: 4924 / 640

Going ahead to step 8:
640 can be fit into 4924 7 times, resulting in a remainder of 444.
Use 7 as the next digit of our solution. 
Result so far: 142087.0
Subtract 4480 from 4924 to get 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Going ahead to step 9:
When dividing 4440 by 640, we get 6 with a remainder of 600.
The number 6 becomes the next digit in our result. 
Result so far: 142087.6
Deduct 3840 from 4440 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Step 10:
640 goes into 6000 9 times with a remainder of 240.
The next digit of our result is 9. 
Result so far: 142087.69
If we subtract 5760 from 6000, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 11:
640 can be fit into 2400 3 times, resulting in a remainder of 480.
Put 3 as the next digit of the answer. 
Result so far: 142087.693
The remainder is 480 after subtracting 1920 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 12:
When dividing 4800 by 640, we get 7 with a remainder of 320.
Put 7 as the next digit of the answer. 
Result so far: 142087.6937
If we take 4480 away from 4800, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 13:
640 can be fit into 3200 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 142087.69375
Subtract 3200 from 3200 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 14:
640 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 142087.69375
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.

Step 15:
0 divided by 640 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 142087.69375
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.

In conclusion, the division gives 142087.69375 with a balance of 0.0.
